[tex]\text{center}=(\frac{3}{2},-\frac{1}{2})[/tex]STEP-BY-STEP EXPLANATION:
The center of the circle would be the mean value between the end points, and we can calculate it like this:
[tex]\begin{gathered} (M_1,M_2)=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}) \\ \text{replacing} \\ (M_1,M_2)=(\frac{-2+5_{}}{2},\frac{-4+3_{}}{2}) \\ (M_1,M_2)=(\frac{3_{}}{2},-\frac{1_{}}{2}) \end{gathered}[/tex](a) Approximate the population mean and standard deviation of age for males And For females.
1) Since we have a table for grouped data, we need to place into that table another column with the middle point of each interval to get the mean.
2) Setting that table with another column we've got:
Age Middlepoint Male Female Male*freq Female*fr
0-9 (0+9)/2 =4.5 10 9 10*4.5=45 9*4.5=40.5
10-19 (10+19)/2=14.5 11 5 159.5 72.5
20-29 (20+29)/2= 24.5 12 13 294 318.5
30-39 (30+39)/2= 34.5 16 19 552 655.5
40-49 (40+49)/2= 44.5 25 21 1112.5 934.5
50-59 (50+59)/2= 54.5 20 24 1090 1308
60-69 (60+69)/2=64.5 18 18 1161 1161
70-79 (70+79)/2= 74.5 15 14 117.5 1043
Now, we can pick the absolute frequency of males and females and multiply by the middle point.
Now we can add the number of males multiplied by the frequency and divide them by the sum of the frequencies, this way:
[tex]\mu=\frac{45+159.5+294+552+1112.5+1090+1161+117.5}{10+11+12+16+25+20+18+15}\approx38.68[/tex]3) Now to find the standard deviation of this population, we can write out the following:
[tex]\begin{gathered} \sigma=\frac{\sqrt[]{(45-38.68)^2+(159.5-38.68)^2+(294-38.68)^2+(552-38.68)^2+(1112.5-38.68)^2+(1090-38.68)^2+(1161-38.68)^2+(117.5-38.68)^2}}{8} \\ \\ \sigma=452.6694 \end{gathered}[/tex]Nanny using using an app that shows him how many kilometers he has to run to prepare for a Marathon.

Find the area, to the nearest thousandth, of the standard normal distribution between the given z-scores.z = 1 and z = 1.81
Since this is a normal distribution, the area between the z-scores z₁ = 1 and z₂ = 1.81 is just the probability that the random variable Z is between z₁ and z₂:
[tex]P(z_1\leq Z\leq z_2)=P(z_1\leq Z)-P(z_2\leq Z_{})=P(1\leq Z)-P(1.81\leq Z)[/tex]Using the values reported on tables for the standardized normal distribution, we know that:

Question 8 of 10What should you multiply the first equation (top equation) by in order toeliminate the variable x when the two equations are added together?(3x-y-14-12x+y - 7dar hereISUBMIT
You can multiply the first equation by 4:
3x - y = 1 (*4)
12x-4y=4
Adding both equations:
12x - 4y = 4
+
-12x + y = 7
__________
0x - 3y = 11
so, you eliminate the X.
In order to eliminate the variable x when the two equations are added together, we needed to multiply the first equation by 4.
To eliminate the variable x when adding the two equations:
First, let's write the equations in a form where the x and y terms have opposite coefficients:
3x - y = 1 (Equation 1)
-12x + y = 7 (Equation 2)
To eliminate the x term, we can multiply Equation 1 by 4:
4 (3x - y) = 4 × 1
12x - 4y = 4 (Equation 3)
Now, we can add Equation 2 and Equation 3 together:
(-12x + y) + (12x - 4y) = 7 + 4
-12x + 12x + y - 4y = 11x - 3y = 11
The x term has been eliminated, and we are left with the equation 11x - 3y = 11.

[tex]y=\frac{3}{4}x[/tex]sunscreen is priced at $10 per bottle, +8% tax. If Tonya purchases a bottle of sunscreen with a $20 bill, then what is her change
Solution
For this case we know that the price is 10$ per bottle with 8% of tax
We can find the tax using this:
[tex]\frac{10}{100}=\frac{x}{8}[/tex]With x= tax value, solving for x we got:
[tex]x=8\cdot\frac{10}{100}=0.8[/tex]Then the total price is: 10+0.8 = 10.8
Then we can find the change like this:
20-10.8= 9.2
30.4. The figure below is going to be enlarged so that the area of the new, similar shape will be 400 cm?. What will the perimeter of the new, enlarged shape be?5 cm24. Perimeter of enlarged shape=cmicm10 cmArea = 100 cm2
Q. 4:
We are asked to find the perimeter of the enlarged shape.
The perimeter of the enlarged shape can be found by multiplying the scale factor with the perimeter of the original shape.
The scale factor is the ratio of the area of the enlarged shape to the area of the original shape.
[tex]SF=\frac{400\;cm^2}{100\;cm^2}=4[/tex]So, the scale factor is 4.
The perimeter of the original shape can be found by adding all the side lengths.
[tex]P=5+4+10+6+3+2=25\;cm[/tex]So, the perimeter of the original shape is 25 cm
Finally, the perimeter of the enlarged shape is
[tex]P=4\times25=100\;cm[/tex]Therefore, the perimeter of the enlarged shape is 100 cm
Two Step problem:STEP 1: 7x^2 = -4using the standard form ax^2 +bx + c =0 of the given quadratic equation, factor the left hand side of the equation into two linear factors. STEP 2: 7x^2 = -4xsolve the quadratic equation by factoring. Write your answer in reduced fraction form, if necessary. PICTURE OF ANSWER BOX ATTACHED: is for step #2
Step 1
x(7x+4)
Step2
x_1=0, x_2 =-4/7
Step 1)
1) Let's factor that incomplete quadratic equation (since c=0):
7x² = -4x Add 4x to both sides
7x² + 4x = 0 Place outside the parenthese the common factor: x
x(7x+4) = 0
Step 2)
Now we can solve that:
x(7x+4)=0 Which number multiplied by x yields 0?
Then we can state that x_1 = 0
Solving that Linear Factor:
(7x +4) = 0 Removing the Parentheses
7x +4 = 0 Subtract 4 from both sides
7x = -4 Divide both sides by 7
x = -4/7
3) Hence, the answers are:
Step 1
x(7x+4)
Step2
x_1=0, x_2 =-4/7

compare a=0.432, b=0.437
So we need to compare two numbers. This means telling which is smaller and which is greater or if they are equal. In this case we have decimal numbers but it's more comfortable to work with integers so I'm going to multiply both by the same number in order to make them integers:
[tex]\begin{gathered} A=0.432\cdot1000=432 \\ B=0.437\cdot1000=437 \end{gathered}[/tex]Since both a and b where multiplied by the same number then the result of the comparison between A and B is the same as that between a and b. So we have 432 and 437. Let's make a substraction:
[tex]A-B=432-437=-5[/tex]The result is a negative number which means that:
[tex]A-B<0[/tex]Then we add B at both sides of this inequality:
[tex]\begin{gathered} A-B+B<0+B \\ AAs I said before the comparison between A and B is the same as that between a and b which means that:[tex]aAnd that last inequality is the answer.Which set of graphs can be used to find the solution to the equation?

The associative property states that the way the factors are grouped in a multiplication does not change the result.
Grouping 7 and 4
13 * (4*7) = 13 *(28 ) = 364
13 and 7
(13*7)*4 = 91*4= 364
13 and 4
(13*4)*7 = 52*7 = 364
So, the correct options are a and b ( the first 2 options)

On any particular Saturday evening, the probability that Hannah will go 1 to the movies and go for a coffee is The probability that she will go
In one deck we have Spades, Clubs, Hearts, and Diamonds. Each one has 13 cards and 3 face cards. So the let's do this step by step. The probability to get a diamond card is:
[tex]P(diamond)\text{ = }\frac{13}{52}[/tex](13 diamond cards in a total of 52). Then the probability to get a face card is:
[tex]P(facecard)\text{ = }\frac{12}{52}[/tex](12 face cards in a total of 52). We have to sum these probabilities but also we have to subtract the possibilities that include a card that is a face card and diamond (because if we don't do that we are going to count these cards two times). This probability is:
[tex]P(DiamondandFaceCard)\text{ = }\frac{3}{52}[/tex](We have only 3 cards in the deck that are diamond and face cards). Therefore, the probability will be:
[tex]\text{Probability = P(diamond) + P(facecard) - P(Diamond and Face Card)}[/tex][tex]\text{Probability = }\frac{13}{52}\text{ + }\frac{12}{52}\text{ - }\frac{3}{52}[/tex][tex]\text{Probability = }0.423[/tex]A rectangle's length is 6 inches greater than its width. If the perimeter of the rectangle is 36 inches, find the length.
We will have the following:
First, we are given the following expressions for the rectangle's length and width respectively:
[tex]l=w+6[/tex]&
[tex]w=w[/tex]Now, we calculate the length and width using the perimeter:
[tex]P=2(l+w)\Rightarrow P=2(w+6+w)\Rightarrow P=2(2w+6)\Rightarrow P=4(w+3)[/tex]So:
[tex]36=4(w+3)\Rightarrow w+3=9\Rightarrow w=6[/tex]Then:
[tex]l=(6)+6\Rightarrow l=12[/tex]So, the measurements of the length and the width are respectively 12 units and 6 units.
