Find the balance in the account. $800 principal earning 7%, compounded annually, after 4 years

1 answer:

Arturiano [62]2 years ago

5 0

Formula for amount, A, in Compound Interest:

A = P(1 + r)ⁿ

Where P = Principal = $800, r = rate per year = 7% = 0.07, n = number of years = 4

A = P(1 + r)ⁿ

A = 800(1 + 0.07)⁴

A = 800(1.07)⁴ Use your calculator

A ≈ 1048.6368

A ≈ $1048.64

I hope this helped.

Which of the following describes how to translate the graph y = |x| to obtain the graph of y = |x + 7|? 7 units up 7 units down

sergij07 [2.7K]

ANSWER

7 units left.

EXPLANATION

The parent function is

$y = |x|$

The transformation

$y = |x + a|$

shifts the graph of the function, a units to the left.

Therefore the transformation that describes how to translate the graph of

y=|x| to obtain y=|x+7| is 7 units left.

The third choice is correct

Solve Please. No Links. Links = Report.

AfilCa [17]

Answer:

Step-by-step explanation:

The easiest way to start is to do this problem is to start changing the 3/4 cup to a decimal

3/4 = 0.75

Now divide that into 11. What you are interested in is the remainder.

11/0.75 = 14.66667

He can make 14 whole pizzas.

He has 0.66667 of a cup left over which is less than 3/4 (or 0.75) so he does not have enough for another pizza.

So the answer is 0.66667 which is 2/3 of a cup is left over.

One sample has Aa Aa One sample has n 10 scores and a variance of s2 20, and a second sample has n 15 scores and a variance of s

siniylev [52]

Answer:

option (a) It will be closer to 30 than to 20

Step-by-step explanation:

Data provided in the question:

For sample 1:

n₁ = 10

variance, s₁² = 20

For sample 2:

n₂ = 15

variance, s₂² = 30

Now,

The pooled variance is calculated using the formula,

$S^{2}_{p} = \frac{(n_{1}-1)\times s^{2}_{1} +(n_{2}-1)\times s^{2}_{2}}{n_{1}+n_{2}-2}$

on substituting the given respective values, we get

$S^{2}_{p} = \frac{(10-1)\times 20 +(15-1)\times 30}{10+15-2}$

or

$S^{2}_{p}$ = 26.0869

Hence,

the pooled variance will be closer to 30 than to 20

Therefore,

The correct answer is option (a) It will be closer to 30 than to 20
