An account with $600 earns 4% simple interest per year. The next year all the money is put into a new account that earns 4.5% simple interest per year. How much money does the account have at the end of the second year? Explain.
The amount of money the account has at the end of the second year will be $51.
What is simple interest?Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time.
Given that An account with $600 earns 4% simple interest per year. The next year all the money is put into a new account that earns 4.5% simple interest per year.
The amount for the first year will be:-
$600 x 0.04 • 1 year
600 x 0.04 = 24 • 1 = 24
The amount for the second year will be:-
$600 x 0.045 • 1 year
600 x 0.045 = 27 1 = 27
For the second year = 24 + 27 = $51
Therefore, the amount of money the account has at the end of the second year will be $51.

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.

Andre looks at a box of paper clips. He says: “I think the number of paper clips in the box is less than 1,000.”
Lin also looks at the box. She says: “I think the number of paper clips in the box is more than 500.”
Write an inequality to show Andre's statement, using p for the number of paper clips.
Write another inequality to show Lin's statement, also using p for the number of paper clips.
Do you think both Lin and Andre would agree that there could be 487 paperclips in the box? Explain your reasoning.
Do you think both Lin and Andre would agree that there could be 742 paperclips in the box? Explain your reasoning.
Answer:
andre: p<1000
Lin: p>500
they would not agree that there are 487 paperclips because both of there guesses are greater than that. they would both agree that there are 742 paperclips because 742 is greater than 500 but less than 1000.

Answer:
x is 23

3x=69
x=23
Answer:
x=23Step-by-step explanation:
in order to find x
(3x+18)° + 93°=180°
⇒3x+18=180-93
⇒3x=180-93-18
x=69/3
x=23
