Nolan invested $5,300 in an account paying an interest rate of 3.8% compounded
annually. Assuming no deposits or withdrawals are made, how long would it take, to
the nearest tenth of a year, for the value of the account to reach $6,880?
HELP
Answer:
7
Step-by-step explanation:
did the question
The amount of money would be $6,880 in the account after 7 years.
What is Compound interest?Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.
A = P(1+r/100)ⁿ
Where:
A = the future value of the investment or loan
P = the principal investment or loan amount
r = the interest rate (decimal)
n = the number of compound periods
Given data as follows:
p = $5,300
r = 3.8%
A = $6,880
A = P(1+r/100)ⁿ
Substitute the values of p,r, and A in the formula,
6,880 = 5,300(1 + 3.8/100)ⁿ
6,880/5,300 = (1 + 0.038)ⁿ
1.2981 = (1.038)ⁿ
n = 6.9954
Rounded to the nearest digit, and we get
n = 7
Therefore, the amount of money would be $6,880 in the account after 7 years.

The pie chart below represents the vehicle types owned by families. If the total number of people surveyed is 1000, approximately how many own a van?
Answer:
500 families
Step-by-step explanation:
We want to estimate the size of the dark blue section of the chart. The chart looks like the left of the pie chart is split evenly with the dark blue section. So we estimate that each of those must represent 12 or 50% of the total number of families. Therefore,
0.50⋅1000=500
About 500 families own a van.
A researcher in sports equipment is investigating the design of racing swimsuits for women. The researcher selected a samp The difference in the sample mean swim times will be calculated. Which of the following is the appropriate inference procedure for analyzing the results?
a) A two-sample t-interval for a difference between sample means
b) A two-sample t-interval for a difference between population means
c) A one-sample t-interval for a sample mean
d) A one-sample t-interval for a population mean
e) A matched pairs t-interval for a mean difference
Answer: B. A two sample t-interval for a difference between population means.
Step-by-step explanation:
The appropriate inference procedure for analyzing the results is the two sample t-interval for a difference between population means.
The two-sample T-interval is simply used in the estimation of the difference that occurs in two population means. Since two independent groups mean are being considered, the appropriate test will then be two sample t-interval for a difference between population means

Step-by-step explanation:
Two sides are the same length, so the angles opposite them are the same size.
The sum of the angles = 180°. One angle is 100°, so the sum of the remaining two angles is 80°.
Since the remaining two angles are congruent, each is 40°.

whats 4 x 2/3 as a multiple of a unit fraction
The expression 4 x 2/3 as a multiple of a unit fraction is 8/3, which is equal to (1/3) x 8.
What is an expression?Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication, and division.
To express 4 x 2/3 as a multiple of a unit fraction, we need to find a fraction that can be multiplied by a whole number to give us 4 x 2/3.
First, we can simplify 2/3 by dividing both the numerator and denominator by their greatest common factor, which is 1. This gives us:
2/3 = 2 ÷ 1 / 3 ÷ 1 = 2/3
Next, we can multiply 4 by 2/3 to get:
4 x 2/3 = 8/3
To express 8/3 as a multiple of a unit fraction, we can use the fact that any fraction can be expressed as a sum of unit fractions. We can start by expressing 1/3 as a unit fraction:
1/3 = 1 ÷ 3
Next, we can multiply both the numerator and denominator of 1/3 by 3 to get:
1/3 = 3 ÷ 9
Now we can express 8/3 as a sum of unit fractions:
8/3 = (3/9) x 8 = (1/3) x 8 = 8 ÷ 3
Therefore, 4 x 2/3 as a multiple of a unit fraction is 8/3, which is equal to (1/3) x 8.
