Select the correct answer from each drop-down menu.
A number is 5 more than 3 times another number. The sum of the two numbers is 33. As an equation, this is written x + 3x + 5 = 33, where x represents the smaller number. Plug in the numbers from the set {3, 5, 7, 9} to find the value of x.
The value of x that holds true for the equation is BLANK 1. So, the smaller number is BLANK 2 and the larger number is BLANK 3.
Blank 1:
3, 5, 7, 9
Blank 2:
3, 5, 7, 9
Blank 3:
24, 26, 28, 30
Answer:
look below. brainliest pls :)
Step-by-step explanation:
Blank 1: 7
Blank 2: 7
Blank 3: 26
To find the value of x, we need to substitute each number from the set {3, 5, 7, 9} into the equation x + 3x + 5 = 33 and see which value satisfies the equation.
Let's try each number one by one:
For x = 3, the equation becomes 3 + 3(3) + 5 = 3 + 9 + 5 = 17, which is not equal to 33.
For x = 5, the equation becomes 5 + 3(5) + 5 = 5 + 15 + 5 = 25, which is not equal to 33.
For x = 7, the equation becomes 7 + 3(7) + 5 = 7 + 21 + 5 = 33, which satisfies the equation.
For x = 9, the equation becomes 9 + 3(9) + 5 = 9 + 27 + 5 = 41, which is not equal to 33.
Therefore, the value of x that holds true for the equation is 7. So, the smaller number is 7 and the larger number can be calculated by adding 5 to it, resulting in 7 + 5 = 12.

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.
