Answer:
[tex] {eb}^{2} = {ab}^{2} + {ea}^{2} \\ {ab}^{2} = {eb}^{2} - {ea}^{2} \\ {ab}^{2} = {20}^{2} - {12}^{2} \\ ab = 16 \\ \\ {db}^{2} = {bc}^{2} + {dc}^{2} \\ {bc}^{2} = {db}^{2} - {dc}^{2} \\ {bc}^{2} = {20}^{2} - {16}^{2} \\ bc = 12 \\ \\ so \: ac = ab + bc \\ ac = 28[/tex]

The conditional relative frequency table below was generated by column using frequency table data comparing the number of calories in a meal to whether the meal was prepared at home or at a restaurant.
A 4-column table with 3 rows titled number of calories and location of meal preparation. The first column has no label with entries greater than or equal to 500 calories, less than 500 calories, total. The second column is labeled home with entries 0.15, 0.85,1.0. The third column is labeled restaurant with entries 0.55, 0.45, 1.0. The fourth column is labeled total with entries 0.28, 0.72, 1.0.
A nutritionist attempts to determine an association between where food is prepared and the number of calories the food contains. Which is most likely true?
An association cannot be determined because the value 0.55 is similar to the value 0.45.
There is an association because the value 0.15 is not similar to the value 0.55.
There is an association because the sum of each column is 1.0.
An association cannot be determined because the sum of the rows going across is not 1.0.
Answers
There is an association because the value 0.15 is not similar to the value 0.55
For the nutritionist to determine whether there is an association between where food is prepared and the number of calories the food contains, there must be an association between two categorical variables.
The conditions that satisfy whether there exists an association between conditional relative frequencies are:
1. When there is a bigger difference in the conditional relative frequencies, the stronger the association between the variables.
2. When the conditional relative frequencies are nearly equal for all categories, there may be no association between the variables.
For the given conditional relative frequency, we can see that there exists a significant difference between the columns of the table in the picture because 0.15 is significantly different from 0.55 and 0.85 is significantly different from 0.45
We can conclude that there is an association because the value 0.15 is not similar to the value 0.55

Answer:
66 cm (Option B)
Step-by-step explanation:
The formula for the circumference of a circle is C = 2πr, so plug the values into the formula. The radius, (r) of a circle is one half of the diameter, so split 21 is half to get a radius of 10.5. Use 3.14 for π.
C = 2πr
C = 2(3.14)(10.5)
C = 6.28 × 10.5
C = 65.94
Rounded to the nearest unit, you get a answer of 66 cm.

Find the number that is exactly half way between -4 and 10
Answers
Answer:
7 as a halfway of a line
3 if you were using points on a graph
Step-by-step explanation:
10--4/2=7
use midpoint formula for 3
The number that is exactly halfway between -4 and 10 is 3
The distance between two point is the amount of length between the two points.
Midpoint of -4 and 10 is 10 - (-4) gives 10 + 4
The distance between -4 and 10 is 14 units
Halfway of the length between -4 and 10 is 14 /2 (7)
The number that is exactly halfway between -4 and 10 = -4 + 7 or 10 - 7 = 3
The number that is exactly halfway between -4 and 10 is 3

Answers
Answer:
= 1 0
Step-by-step explanation:
Solve
1. Combine like terms
2 + 2 0 + 2 = 6 0
4 + 2 0 = 6 0
2. Subtract 20 from both sides of the equation
4 + 2 0 = 6 0
4 + 2 0 − 2 0 = 6 0 − 2 0
3. Simplify
Subtract the numbers4 + 2 0 − 2 0 = 6 0 − 2 0
4 = 6 0 − 2 0
Subtract the numbers4 = 6 0 − 2 0
4 = 4 0
4. Divide both sides of the equation by the same term
4x = 40
4x/4 = 40/4
5. Simplify
Cancel terms that are in both the numerator and denominator4x/4 = 40/4
x = 40/4
Divide the numbersx = 40/4
x = 10

Answers
Answer:
she had a perfect score in 1/8 of all tests
she had a perfect score in 4 tests
Step-by-step explanation:
Tamara earned an A in 5/8 of all the tests she took.
In 1/5 of the those tests she got an A, she had a perfect score.
1/5 of 5/8 is 1/5 * 5/8 which equals 5/40 which can be reduced to 1/8.
That means that in 1/8 of all tests she took she got a perfect score.
She took a total of 32 spelling tests.
1/8 of 32 = 1/8 * 32 = 32/8 = 4
Answer:
she had a perfect score in 1/8 of all tests
she had a perfect score in 4 tests
