On>5
On <5
The inequality represents a number no more than 5 is n < 5.
What is inequality?
In mathematics, inequalities describe the relationship between two values that are not equal. Equal means to be equal, not. The "not equal symbol (≠)" is typically used to indicate that two values are not equal. But different inequalities are used to compare the values to determine whether they are less than or greater than.
We have to find which inequality represents a number no more than 5.
Consider, the first inequality n ≤ 5.
This inequality contain 5 and less numbers.
Consider the second inequality n ≥ 25
This inequality contain numbers 5 and more
For n > 5
This inequality contain numbers more than 5.
For n < 5
This inequality does not contain number more than 5.
Hence, the inequality represents a number no more than 5 is n < 5.

emily has gotten c's on her first three accounting exams. each exam is worth 25% of her final grade. even though she wants an a in the class, she is not planning to study harder for the fourth (and last) exam. which part of expectancy theory might explain why?
Emily can't get an A in the class, even if she gets an A on the last exam. This expectancy theory might explain.
Expectancy theory suggests that indivisuals are motivated to perform if they know that their extra performance is recognized and rewarded. Consequently companies using performance-based pay can expect improvements.
Expectancy theory explains the process of why someone chooses one behavior over another. In making this conclusion choice, there are three elements considered: expectancy, instrumentality and valence.
Expectancy is the belief that your effort will lead to better performance.
Instrumentality is the trust that if you perform well you will achieve the outcome you expect.
Valence is the how important you feel the outcome, and any related reward is to you personally.

Whitney wants to save up some money to buy a new smartphone, so she babysits on the weekends.
There is a proportional relationship between the time Whitney spends babysitting (in hours), x, and the amount of money she earns babysitting (in dollars), y
Given the proportional relationship between the time Whitney spends babysitting (in hours), x, and the amount of money she earns babysitting (in dollars), y, she needs to babysit for 2 hours to earn $12.
What is a proportional relationship?A proportional relationship refers to the relationship between two or more values with equal ratios.
Proportions are relative values or ratios, depicted in fractions, percentages, or decimals.
Equation, y = 6x
Where y = the amount of money Whitney earns babysitting (in dollars)
And x = the hours of babysitting
If y = $12, the number of hours that Whitney needs to babysit is 2 hours ($12/$6)
y = 6x
6x = y
x = y ÷ 6
x = 12 ÷ 6
x = 2
Check:
12 = 6x
12 = 6(2)
12 = 12
Thus, based on the equation modeling the proportional relationship, Whitney should work 2 hours.

Find the line of fit (1960, 23) and (2000, 32)
The line of fit for the coordinate points (1960, 23) and (2000, 32) is y=9/40 x+418.
The given coordinates are (1960, 23) and (2000, 32).
What is line of fit?The line of best fit calculates a straight line that minimises the separation between itself and the locations of the observations in a given data collection. A trend or correlation between the dependent variable and the independent variable is depicted using the line of best fit (s). It can be expressed mathematically or graphically.
In the coordinate points (1960, 23) and (2000, 32)
In (1960, 23), 1960 is x-coordinate and 23 is y-coordinate
In ((2000, 32), 2000 is x-coordinate and 32 is y-coordinate
Here, Slope =(y2-y1)/(x2-x1)
= (32-23)/(2000-1960)
= 9/40
Substitute m=9/40 and (x, y)=(1960, 23) in y=mx+c, we get
23= 9/40 (1960)+c
23= 9×49+c
c=23-441=418
Substitute m=9/40 and c=418 in y=mx+c, we get
y=9/40 x+418
Hence, the line of fit for the coordinate points (1960, 23) and (2000, 32) is y=9/40 x+418.

A penny collection contains twelve 1967 pennies, seven 1968 pennies, and eleven 1971 pennies. If you are to pick some pennies without looking at the dates, how many must you pick to be sure of getting at least four pennies from the same year?.
Answer:
Pick at least four pennies to be sure of getting at least four pennies from the same year.
Step-by-step explanation:
To be sure of getting at least four pennies from the same year, you would need to pick at least four 1967 pennies, four 1968 pennies, or four 1971 pennies. Since these are the three smallest groups of pennies, you would need to pick at least four pennies to be sure of getting at least four pennies from the same year.
At intel, the thickness of processor chips has a mean of 1 mm with a standard deviation of 0. 2 mm. Multiple random samples, each consisting of 35 processor chips, are taken. The sample mean and standard deviation for each sample are recorded to form a sampling distribution. What is the mean and standard deviation of this sampling distribution?.
The mean of this sampling distribution is 1 cm, the standard deviation is 0.033, X-bar is called the sampling distribution of the sample mean
The square root of the variance is used to calculate the standard deviation, a statistic that expresses how widely distributed a dataset is in relation to its mean. By calculating the departure of each data point from the mean, the standard deviation may be determined as the square root of variance.
The bigger the deviation within the data collection, the more the data points deviate from the mean; hence, the higher the standard deviation, the more dispersed the data.
Processor chips = 35
Let the x-bar be the sample mean
x-bar = 1 mm
Size of the processor chips = 0.2 mm
n = 35
Standard deviation = Size of the processor chips/[tex]\sqrt{n}[/tex]
= 0.2/[tex]\sqrt{35}[/tex]
= 0.2/5.9160
= 0.033
Standard deviation = 0.033

Hope this helps!
Answer:
(i)The train takes 0625 hours to travel from Town A to Town B.
(ii)The distance between Town A and Town B is 693 km.
Step-by-step explanation:
(i)
Leaving time of the Train from Town A= 0845 hours.
Arriving time of the Train at Town B= 1510 hours.
Thus, the total time taken by the train to travel from Town A to Town B is:-
=> Arrival time at Town B - Departure time from Town B = (0845-1510)hours
= 0625 hours.
Therefore, the total time taken by the train to travel from Town A to Town B is 0625 hours.
(ii)
The average speed of the train is 108 km/h.
The total time taken by the train is 0625 hours, which can also be
expressed as
6 5/12 hours,

When aked her age,uan replied "if you take my age an quare it and then ubtract 22 time my age the reult i 75"how old i he?
After solving, she is 25 years old.
In the given question,
When he asked her age, She replied "If you take my age and square it and then subtract 22 time my age then the result is 75"
We have to find the age of she.
To find the age of she we we firstly simplify the given statement in the form of expression then we solve the expression.
To write the expression we clearly read then sentence and then write the expression.
Let the age of she is x.
So When we take the square of her age, it is x^2.
When we subtract 22 times her age then it is x^2-22x.
Then its is equal to the 75. Now the expression is;
x^2-22x=75
Subtract 75 on both side, we get
x^2-22x-75=0
Now we simplifying the equation by factoring it.
x^2-(25-3)x-75=0
x^2-25x+3x-75=0
x(x-25)+3(x-25)=0
(x+3)(x-25)=0
Now the factor of x is -3 and 25.

The total amount they will pay = $95.557
What is the percentage?
It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
The Latin word "per centum," which means "by the hundred," is where the word "percentage" originally came from. With 100 as the denominator, percentages are fractions. To put it another way, it's the relationship between a component and a whole in which the value of the whole is always assumed to be 100.
Cost of meal = $75.99
tax amount = 6.75% of 75.99
= ( 6.75/100 ) * 75.99
= $5.129
Tip amount = 19% of 75.99
= (19/100)*75.99
= $14.438
Total amount they will pay = $75.99 + $5.129 + $14.438 = $95.557

How do you find the domain and range of a square root graph?
Domain and range of a square root graph is [0, ∞) and [0, ∞) respectively.
Domain of a function:
The domain of a function is the set of input values (x) for which it produces an output value.
Range of a function:
The set of all output values of a function.
Like if we consider a function [tex]y = f(x)[/tex]
then input inside function that is x is know as domain of function
output of function that is y is known as range of function.
First we write square root function as y = [tex]\sqrt{x}[/tex]
So inside root negative numbers are not allowed so value of x should be positive numbers means x>=0.
So domain of square root function [0, ∞).
Output of square root function is always positive so range of square root function is also [0,∞).

Monica would like to save up $10,000. She is going to make monthly deposits for 5 years into an account that will get 2.05% compounded monthly. How much does she need to deposit in the account to reach her goal?
Answer: $91017.17865 / 12 = $7585.5987
Step-by-step explanation:
To solve this problem, we need to first determine the total interest that will be earned on the account over the 5-year period. We can do this by using the formula for compound interest, which is:
A = P (1 + r/n) ^ nt
where A is the total amount of money in the account after the interest has been compounded, P is the initial deposit, r is the interest rate, n is the number of times the interest is compounded per year, and t is the number of years the money is deposited.
In this case, the initial deposit is $10,000, the interest rate is 2.05%, the number of times the interest is compounded per year is 12 (because the interest is compounded monthly), and the number of years the money is deposited is 5. Plugging these values into the formula, we get:
A = 10000 (1 + 0.0205 / 12) ^ (12 * 5)
A = 10000 (1.001708333) ^ 60
A = 10000 (1.101717865)
A = 101017.17865
Therefore, the total amount of money in the account after 5 years will be $101017.17865.
Since Monica wants to save up $10,000, we can subtract this amount from the total amount in the account to find out how much she needs to deposit each month in order to reach her goal:
101017.17865 - 10000 = 91017.17865
Therefore, Monica needs to deposit $91017.17865 each month in order to save up $10,000 in 5 years. This means that she will need to deposit $91017.17865 / 12 = $7585.5987 per month in order to reach her goal.
How do you find the maximum value of a set?
The ven diagram from set theory must be used to determine the highest value and minimum value in a set.
We're using this as an illustration.
Let A and B represent two sets with 4 and 7 items, respectively. The maximum number of elements that A and B can have is then written.
So let's assume:
A's element count is equal to n. (A).
B's element count is equal to n. (B).
The sum of the elements of A and B is n (A and B).
Now, here is the equation for the components of A U B:
n(A∪B)=n(A)+n(B)−n(A∩B)
The answer to the question states that set A's element count is four, whereas set B's element count is seven. We can thus write:
The number of elements that are included in both sets A and B is represented by the numbers n (A) = 4 and n (B) = 7.
The maximum number of elements in n(A,B) must be determined. Therefore, when n(AB) is smallest and when n(AB) is zero, n(AB) is at its maximum.
n(A∪B)=n(A)+n(B)−n(A∩B)⇒n(A∪B)=4+7−0⇒n(A∪B)=11
Hence, the maximum number of elements in A∪B is 11.
You might be asking why n (AB) must be minimized in order to be maximized, and why the minimal value of n (AB) is 0.
In the formula for n (A∪B),
n(A∪B)=n(A)+n(B)−n(A∩B)
L.H.S will be maximized when in the R.H.S; the term after minus sign will be minimized. Hence, n (A∩B) must be minimized.
The fact that n (AB) can take on any value less than 0 indicates that there are no elements in sets A or B that are shared by both sets. Furthermore, it's possible that the two sets we have don't share any elements.
When no elements is common in both the sets, the n (A∩B) is ∅.
The set which has no element in it is called a null set or an empty set.
By this we can find maximum value in a set.

The minimum sample size is 11 needed to be 90% confident that the sample mean is within 1 point of the true population mean.
What is the mean?
Mean, in terms of math, is the total added values of all the data in a set divided by the number of data in the set.Given:
Standard deviation, σ = 2points
Confidence level = 90%
Sample mean, ε = 1 point
At 90% confidence level
1 - α = 0.90
α = 1 -0.90
α = 0.10
α/2 = 0.05
Zα / 2 = Z₀.₀₅
= 1.645
To find n
n = (Zα / 2 )*(σ)²
= (1.645)² * (2)² / (1)²
= (2.706) * 4
= 10.8241
n = 11

therefore, the smaller the divisor, the more often it fits into the dividend.
the quotient must be greater than 4. so, 4 itself is not a valid quotient for this problem.
but let's start with it :
16 / 4 = 4.
so, a = 4 (B) is not a valid solution.
to make the quotient larger (than 4), a must be smaller than 4.
the only valid solution is
A a = 2
except for C all other answer options are larger than 4 making the quotient smaller than 4.
and C is negative, which would make the quotient negative and therefore smaller than 4.
so, A is the only remaining valid answer.
16/2 = 8
perfect. the quotient (8) is larger than 4.
Which is a solution to the equation |10-5y|=20
y=2
ОУ-4
y-6
y=10
Answer:
y=6
Step-by-step explanation:
**THE ANSWER IS POSITIVE! WHAT I GOT WAS A NEGATIVE SINCE THE CLOSEST ANSWER WAS 6.**
Since 5 × -6 is -20, we would subtract that with the 10.
So, 10-5(-6) = -20.
