Answer:

The area is 176.6

Step-by-step explanation:

The formula for the area of a circle is "πr²"

This means you square the radius, and multiply it by pi.

Our diameter is 15, and the radius is half of the diameter.

15 ÷ 2 = 7.5

Next, we square the radius. (7.5)

Let's fill it into the formula.

π7.5²

After squaring, it's this:

π56.25

In your question, pi is 3.14, so let's replace that.

(3.14)56.25

After multiplying we get 176.625, after we round, we get 176.6

176.6 is the area.

a man deposits 45 into an account the next day he makes 3 deposits of 20 $ each a week later he withdraws 105$
zheka24 [161]

Answer:

The amount available in account at last is $0  

Step-by-step explanation:

Given as :

The withdrawal amount from the account at the end = $105

The first deposit amount = $45

The next three deposit amount = $20 each

I.e The second deposit amount = 3 × $20

Or, The second deposit amount = $60

Let The amount available in account at last = $A

<u>Now, According to question</u>

The amount available in account at last = (first deposit amount  + second deposit amount) - withdrawal amount from the account at the end

i.e A = ($45 + $60) - $105

Or, A = $105 - $105

∴  A = $0

So, The amount available in account at last = A = $0

Hence, The amount available in account at last is $0   . Answer

The national weather service keeps records of rainfall in valleys. Records indicate that in a certain valley the annual rainfall
Setler79 [48]

Answer:

The mean is 95 and the standard deviation is 2

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this question:

Population:

Mean 95, Standard deviation 12

Samples of size 36:

By the Central Limit Theorem,

Mean 95

Standard deviation s = \frac{12}{\sqrt{36}} = 2
