It a popular math theorem, that any natural number can be factored out into prime numbers. For example the number 24 is factored as 2³*3, so its prime factors are 2 and 3.
In this case, we want to factor 124. We start by noticing that 124 is an even number, therefore, the first prime factor we try is 2. Next, we divide 124 by 2. We get
[tex]\frac{124}{2}=62[/tex]which is again an even number. This means that we can again divide by 2. We do so
[tex]\frac{62}{2}=31[/tex]Note that 31 is a prime number. So we can't continue dividing. Then
[tex]124=2\cdot2\cdot31=2^2\cdot31[/tex]So it has 2 different prime factors
Felipe is a software salesman. His base salary is $2100, and he makes an additional $70 for every copy of math is fun he sells. Let P represent his total pay in dollars, and let N represent the number of copies of math is fun he sells. Write an equation relating P to N then use this equation to find his total pay if he sells 27 copies of math is fun.
Based on the given information, we can determine the constant and the variable payment.
• He gets $2100 as based salary (never changes, constant).
,• The additional $70 depends on ,N ,(variable).
This information can help us build the equation:
[tex]P=70N+2100[/tex]Therefore, if he sells 27 copies, then the total payment is:
[tex]P=70\cdot27+2100[/tex][tex]P=1890+2100[/tex][tex]P=3990[/tex]Answer:
[tex]P=70N+2100[/tex]P( 27 ) = $3990
In ABC, A = 68°, a = 14 and c = 17. Which of these statements best describes the triangle?
Given for the triangle ABC:
[tex]\begin{gathered} \angle A=68\degree \\ a=14,c=17 \end{gathered}[/tex]Using the sine rule, we will solve the triangle by finding the missing angles
So,
[tex]\frac{a}{\sin A}=\frac{c}{\sin C}[/tex]substitute with the given data:
[tex]\begin{gathered} \frac{14}{\sin68}=\frac{17}{\sin C} \\ \\ \sin C=\frac{17}{14}\cdot\sin 68=1.125866 \end{gathered}[/tex]The value of (sin C) must be 1 or less than 1
So, the triangle ABC cannot be constructed
The answer will be the last option
How to graph inequalities y + 6 < 10 or 2y - 3 > 9
We need to graph on the number line the solution to the compounded inequality
[tex]\begin{gathered} y+6<10 \\ \text{or } \\ 2y-3>9 \end{gathered}[/tex]In order to do so, let's work with each inequality separately. The final solution will be the union of the two solutions since it can be one "or" the other.
Step 1
Subtract 6 from both sides of the first inequality:
[tex]\begin{gathered} y+6<10 \\ \\ y+6-6<10-6 \\ \\ y<4 \end{gathered}[/tex]So, the solution to the first inequality is all real numbers less than 4 (not included). Therefore, we graph this solution using an empty circle:
Step 2
Add 3 to both sides of the second inequality, and then divide both sides by 2:
[tex]\begin{gathered} 2y-3+3>9+3 \\ \\ 2y>12 \\ \\ \frac{2y}{2}>\frac{12}{2} \\ \\ y>6 \end{gathered}[/tex]Thus, the solution to this inequality is all the real numbers greater than 6 (not included: empty circle):
Answer
Therefore, the solution to the compounded inequalities is the union of both solutions:

hello
the function given is
Hello. I need help with this practice problem. I will include a picture. Thank you soo much
Firstly, we need to compare the information ew have from both sides of the equation, the denominators.
The different between the denominator is that the right side has the factor (w + 6), while the lest side does not.
So, sstarting from the expression on the left side, we can introduce the factor (w + 6) into the denominator by multiplying both the numerator and the denominator by this factor:
[tex]\frac{2}{w+7}=\frac{2}{w+7}\cdot\frac{w+6}{w+6}=\frac{2(w+6)}{(w+7)(w+6)}[/tex]The order of the factor dont change the result, so we can switch the factors on the denominator to get:
[tex]\frac{2}{w+7}=\frac{2(w+6)}{(w+6)(w+7)}[/tex]Now, by comparison, we can see that the blank part is the following:
[tex]2(w+6)[/tex]The fox population in a certain region has a continuous growth rate of 9 percent per year.
SOLUTION
The function can be derived from the model
[tex]\begin{gathered} P=P_oe^{(\ln r)t^{}} \\ \\ r\text{ here represents 1 + 9 percent growth rate } \end{gathered}[/tex]So the function becomes
[tex]P(t)=2000_{}e^{(\ln 1.09)t}[/tex]So the fox population in 2008
2008 - 2000 = 8
So our t becomes 8
The population becomes
[tex]\begin{gathered} P=2000_{}e^{(\ln 1.09)t} \\ P=2000_{}e^{(\ln 1.09)\times8} \\ P=\text{ }2000_{}e^{0.086177\times8} \\ =2000_{}e^{0.6894} \\ =\text{ 3985.04} \end{gathered}[/tex]So the Population = 3985

Larry Mitchell invested part of his $22,000 advance at 2% annual simple interest and the rest at 6% annual simple interest if his total yearly interest from both accounts was $760 find the amount invested at each rate The amount invested at 2%The amount invested at 6%( please don’t need an detailed explanation just the answer)
Larry Mitchell invested part of his $22,000 advance at 2% annual simple interest and the rest at 6% annual simple interest if his total yearly interest from both accounts was $760 find the amount invested at each rate
The amount invested at 2%
The amount invested at 6%
Let
x -----> amount invested at 2%
(22,000-x) -----> amount invested at 6%
we have that
x(0.02)+(22,000-x)(0.06)=760
solve for x
0.02x+1,320-0.06x=760
0.06x-0.02x=1,320-760
0.04x=560
x=14,000
(22,000-14,000)=8,000
therefore
amount invested at 2% -----> $14,000amount invested at 6% -----> $8,000751 body temperature measurements were taken. The sample data resulted in a sample mean of 98.1 F and a sample standard deviation of 0.7 F. Use the traditional method and a 0.05 significance level to test the claim that the mean body temperature is less than 98.6 F.
The mean value of the sample is 98.1 F and its standard deviation is 0.7 F.
The margin of error of the mean value is given by 0.7/sqrt(751) = 0.7/27.4 = 0.026 (rounded to the nearest thousandth)
Using the Z test, we got: Z = (98.6 - 98.1)/(0.026) = 0.5/0.026 = 196
Therefore, the mean value of the sample is incompatible with 98.6 and we can claim that the mean body temperature is less than it.
is 13/4 and 21/4 equivalent an equivalent fraction?
To determine if they are equivalent we equal them and if when simplified they do not show the same values, they are not. That is:
[tex]\frac{13}{4}=\frac{21}{4}\Rightarrow3.25\ne5.25[/tex]From that, we can see that they are not equivalent fractions.

Is the solution to this equation viable in this context?
The solution
viable because she
From the given data , the required equation to find the number of popsicles 'p' which Miriam can buy is given by 1.75p +5 = 1.80p + 4.39 is equal to p =12 .
Solution is viable as we can take the nearest round off value to find the number of popsicles.
As given in the question,
Two different companies where Miriam want to spend same amount of her money.
Equation of Food Hub sells is:
1.75p + $5.00
Equation of Foodie eat sells:
1.80p + $4.39
Where p is the number of popsicles
Required relation to get the value of p we have,
1.75p + 5.00 = 1.80p + 4.39
Take like terms on same side we get,
1.80p - 1.75p = 5.00 -4.39
⇒ 0.05p = 0.61
⇒ p = 12.2
⇒ p = 12 (round off number)
Number of popsicles cannot be in decimals.
Solution is viable as we can take the nearest round off value to find the number of popsicles.
Therefore, from the required equation to find the number of popsicles 'p' which Miriam can buy is given by 1.75p +5 = 1.80p + 4.39 is equal to p =12
Solution is viable as we can take the nearest round off value to find the number of popsicles.

Write an equation for the line parallel to the given line that contains B. B(3, 8) ; y = - 4x + 7
You have to write an equation parallel to the line: y=-4x+7 that crosses the point (3,8)
One characteristic that two parallel lines share is that they have the same slope.
The slope for the known line corresponds to the coefficient multiplying the x-term and is m=-4
The line you have to find must have the same slope.
Using the point-slope form you can determine said line. The general structure is:
[tex]y-y_1=m(x-x_1)[/tex]Where
m is the slope
x₁, y₁ are the coordinates of a point crossed by the line.
Using (3, 8) and m=-4
[tex]y-8=-4(x-3)[/tex]Now you have to solve it and write it in slope-intercept form. First step is to solve the term in parentheses by applying the distributive propperties of multiplication:
[tex]\begin{gathered} y-8=-4x-3\cdot(-4) \\ y-8=-4x+12 \end{gathered}[/tex]Next pass "-8" to the other side of the equal sign:
[tex]\begin{gathered} y-8+8=-4x+12+8 \\ y=-4x+20 \end{gathered}[/tex]The equation for the line parallel to y=-4+7 is y=-4x+20

50%
1) Gathering the data
12 are 6th graders
18 7th graders
6 8th graders
2) Let's add them up at first to get the whole number of students who tutor:
12 +18 +6 = 24 +12 = 36
So we can say that
36 -------------- 100%
The 7th graders: 18 students
So we can write a proportion for that
36-------100%
18 ------- x
36x = 1800 Divide both sides by 36
x =50
3) So the answer is 50% of them are 7th graders.

[tex]M+P[/tex]For addition operation to be defined, the Order of the matrices must be the same
The order of matrix M is 4 x 2 while the order of matrix P is 2 x 2
Since the order of the matrices are not the same then the operation is not defined
For the operation
[tex]Q+P[/tex]For addition operation to be defined, the Order of the matrices must be the same
The order of matrix Q is 2 x 1 while the order of matrix P is 2 x 2
Since the order of the matrices are not the same then the operation is not defined
Find the mean with and without the outlier: 66, 55, 65, 44, 54, 10
Answer:
To calculate the mean of the set of values with the outlier, we will use the formula below
Concept:
An outlier is an observation that lies an abnormal distance from other values in a random sample of a population.
The mean with the outlier will be
[tex]mean=\frac{total\text{ addition of numbers}}{number\text{ of data}}[/tex]By substituting the value, we will have
[tex]\begin{gathered} mean=\frac{66+55+65+44+54+10}{6} \\ mean=\frac{294}{6} \\ mean=49 \end{gathered}[/tex]Hence,
The mean of the data with the outlier is = 49
the table shows the probability distrubution of a random variable Z.Z- -17, -16,-15,-14,-13 P(Z)- 0.02 , 0.73, 0.02, 0.08, 0.15what is the mean of the probability distrubution
In order to find the mean, we have to multiply each value with its probability and then add al the results:
Step 1- multiplying each value by its probabilityStep 2 - adding all the resultsNow, we add all the results we found on the previous step:
Mean = -0.34 - 11.68 - 0.30 - 1.12 - 1.95
Mean = -15.39
Answer: mean = -15.39
Which equation is correct? (6 points)Group of answer choicessec x° = opposite ÷ adjacentcot x° = opposite ÷ adjacentcosec x° = opposite ÷ adjacentsec x° = hypotenuse ÷ adjacent
Answer:
Concept:
To figure this question out, we will use the trigonometric ratios below
SOH CAH TOA
[tex]\begin{gathered} SOH \\ sin\theta=\frac{opposite}{hypotenus}=S=\frac{O}{H} \\ \cos\theta=\frac{adjacent}{hypotenus}=C=\frac{A}{H} \\ \tan\theta=\frac{opposite}{adjacent}=T=\frac{O}{A} \end{gathered}[/tex]Using the inverse trigonometric identity,
[tex]\begin{gathered} cosecx^0=\frac{1}{sinx^0} \\ secx^0=\frac{1}{cosx^0} \\ cotx^0=\frac{1}{tanx^0} \end{gathered}[/tex]By simplifying further, we will have that
[tex]\begin{gathered} cosecx^0=\frac{1}{s\imaginaryI nx^{0}} \\ cosecx^0=\frac{1}{\frac{opposite}{hypotenu}}=1\times\frac{hypotenus}{opposite} \\ cosecx^0=\frac{hypotenus}{opposite} \end{gathered}[/tex][tex]\begin{gathered} secx^{0}=\frac{1}{cosx^{0}} \\ secx^0=\frac{1}{\frac{adjacent}{hypotenus}}=1\times\frac{hypotenus}{adjacent} \\ secx^0=\frac{hypotenus}{adjacent} \end{gathered}[/tex][tex]\begin{gathered} cotx^{0}=\frac{1}{tanx^{0}} \\ cotx^0=\frac{1}{\frac{opposite}{adjacent}}=1\times\frac{adjacent}{opposite} \\ cotx^0=\frac{adjacent}{oppos\imaginaryI te} \end{gathered}[/tex]Hence,
The final answer is
[tex]\Rightarrow secx^0=\frac{hypotenus}{adjacent}[/tex]
