Answer:
4/9 and 8/9
Step-by-step explanation:
[tex]\frac{2}{3}[/tex] and [tex]\frac{2}{9}[/tex] you have to have a common denominator so you take 3 and 9 and find what they both go into and that number is 9 so take 2/3 and times the top and bottom by 3 to get 6/9 and 2/9 by 1 to get 2/9 once you have those subtract them to get 4/9 and that's your first answer then take them and add so you get 8/9 which is your second answer.

Step-by-step explanation:
Elena would like to know the average height of seventh graders in her school district. She measures the heights of everyone in a random sample of 20 students. The mean height of Elena's sample is 62 inches, and the MAD (mean absolute deviation) is 2 inches. SELECT ALL TRUE STATEMENTS.
a. The median height of the sample must be between 59 and 63 inches.
b. Another random sample of 20 students is likely to have a mean between 57 and 65 inches
c. The mean height of these 20 students is likely to be the same as the mean height of all students in the district.
d. The mean height of these 20 students is likely to be the same as the mean height of a second random sample of 20 students.
e. Elena would be more likely to get an accurate estimate of the mean height of the population by sampling 40 people instead of sampling 20 people.
The statements that are true are:
- Another random sample of 20 students is likely to have a mean between 57 and 65 inches
- Elena would be more likely to get an accurate estimate of the mean height of the population by sampling 40 people instead of sampling 20 people.
Options B and E are the correct answer.
What is a mean?It is the average value of the set given.
It is calculated as:
Mean = Sum of all the values of the set given / Number of values in the set
We have,
a.
The median height of the sample must be between 59 and 63 inches.
This statement cannot be determined based on the given information.
The MAD provides information about the variability of the data, but not necessarily about the location of the median.
b.
Another random sample of 20 students is likely to have a mean between 57 and 65 inches.
This statement is likely to be true.
Since the sample mean is 62 inches and the MAD is 2 inches, it is reasonable to expect that another random sample of the same size would have a similar mean, within a few inches.
c.
The mean height of these 20 students is likely to be the same as the mean height of all students in the district.
This statement is uncertain.
The sample mean can be a good estimate of the population mean if the sample is representative, but we cannot be certain without more information about the sampling method.
d.
The mean height of these 20 students is likely to be the same as the mean height of a second random sample of 20 students.
This statement is uncertain.
The mean of a second random sample of the same size could be different due to random sampling variation.
e.
Elena would be more likely to get an accurate estimate of the mean height of the population by sampling 40 people instead of sampling 20 people.
This statement is likely to be true.
Generally, larger sample sizes tend to provide more accurate estimates of population parameters, as they are less affected by random sampling variation.
Thus,
The statements that are true are:
- Another random sample of 20 students is likely to have a mean between 57 and 65 inches
- Elena would be more likely to get an accurate estimate of the mean height of the population by sampling 40 people instead of sampling 20 people.

Karl needs to build a stage that has an area of 84 square feet. The length of the stage should be longer than the width. What are the possible whole number measurements for the length and width of the stage?
Complete the table with possible measurements of the stage.
Answer:
84 = L x w
84 = 84 x 1
84 = 42 x 2
84 = 28 x 3
84 = 21 x 4
84 = 14 x 6
84 = 12 x 7

c = cream cheese
Given
b = 30
c = 2
Work:
0.85b+2.5c
0.85(30) + 2.5(2)

What is the radius, in centimeters, of a circle that has a circumference of 16π?
8
16
32
64
Answer: The radius equals 8cm
Answer:
8
Step-by-step explanation:
The circumference of a circle is equal to π , which is a number ≈ 3.14 , multiplied by the diameter of the circle.
Therefore, C = π d .
We know that the circumference, C , is 16 π , so we can say that:
16 π = π d
We can divide both sides by π to see that 16 = d .
We now know that the diameter of the circle is 16 .
We also know that the diameter has twice the length of the radius.
In equation form: 2 r = d
2 r = 16
r = 8
Note that since 2 r = d , the equation C = 2 π r holds and can be used in place of C = π d .

An art teacher makes a batch of purple paint by mixing 3/4 cup red paint with 3/4 cup of blue paint. If she mikes 13 batches, how many cups of purple paint will she have?
Answer:
She will have 19 ¹/₂ batches of purple paint
Step-by-step explanation:
r + b = 1 bp
³/₄ r + ³/₄ b = 1 bp
(³/₄ + ³/₄) * 13 = x bp
⁶/₄ = 1 ¹/₂
1 ¹/₂ * 13 = 13 ¹³/₂ = 19 ¹/₂ batches
VARIABLE KEY:
r = red
b = blue
bp = batches of purple
x = total number of bp
