Answer:
4)P = $615.38. 5)P = $1,482.35
Step-by-step explanation:
<u>4)P = $615.38</u>
Equation:
P = A / (1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year.
Solving our equation:
P = 640 / ( 1 + (0.04 × 1)) = 615.38461538462
P = $615.38
The principal investment required to get a total amount, principal plus interest, of $640.00 from simple interest at a rate of 4% per year for 1 years is $615.38.
<u>2)P = $1,482.35</u>
Equation:
P = A / (1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 12%/100 = 0.12 per year.
Solving our equation:
P = 2016 / ( 1 + (0.12 × 3)) = 1482.3529411765
P = $1,482.35
The principal investment required to get a total amount, principal plus interest, of $2,016.00 from simple interest at a rate of 12% per year for 3 years is $1,482.35.
Answer:
Step-by-step explanation:
we are given equation as
Firstly, we will move all terms on left side
Subtract both sides by 20
Add both sides by 7x
now, we can compare it with quadratic equation
and we get
Given:
The following data set represents the scores (out of 100 points).
94 78 79 97 95 84 80
82 94 92 88 88 99 72
We will find the mean of the data as follows:
We will find the sum of the scores:
And the number of the dataset = 14
So, the mean will be as follows:
Rounding to the nearest tenth
So, the answer will be: The mean = 87.3
Answer:
Step-by-step explanation:
Answer:
$120
Step-by-step explanation:
40x2.00 = 80
80 + 40 = 120
