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

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.

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

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.

a family of four went out to dinner. the cost of their meal was $75.99. Tax on the meal is 6.75% and they left a 19% tip on the cost of the meal. what is the total amount they will pay
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

Work out the area of the tapezium ABDE.
The area of the trapezium, if CD = 8 cm, BD = 6 cm, AE = 9 cm, is 30 cm².
What is area?The measurement that expresses the size of a region on a plane or curved surface is called an area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.
Given:
CD = 8 cm,
BD = 6 cm,
AE = 9 cm,
Here you can see that the triangle AEC and triangle BDC are similar, so the ratio of sides of a triangle are also equal,
BD / AE = CD / CE
6 / 9 = 8 / CE
CE = 9 × 8 / 6
CE = 12 cm
Thus, DE = CE - CD.
DE = 12 - 8 = 4 cm
Calculate the area as shown below,
[tex]Area = (BD+AE) / 2 \times DE[/tex]
Area = (6 + 9) / 2 × 4
Area = 15 / 2 × 4

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.
