Answer:

$4.75

Step-by-step explanation:

The expression given for then average cost is :

(3n + 7 / n)

If the number of games, n = 4

The average cost becomes :

(3n + 7) / n

Put n = 4 in the equation

(3(4) + 7) / 4

(12 + 7) / 4

19 / 4

= 4 3/4

= $4.75

A regular hexagon rotates counterclockwise about its center. It turns through angles greater than 0° and less than or equal to 3
Bogdan [553]
Hey there Caleb!

To start of, the sentence was clear on that it said . . . 

\boxed{A \ regular \ hexagon \ rotates \ counterclockwise \ about \ its 
 \ center }

The statement listed above is the (key) point. We need to keep this in mind.

So, now that we know this.

We would use the mathematic (Ф)

So,sense we know that a (hexagon) had it's (6) shapes, we would do . . . 

Ф = 360° : 6 = 60°

Your correct answer to this question would be . . . 

\boxed{\boxed{60}}

Hope this helps.

Hello! Can you please help me on these two problems? =)
poizon [28]

Yeah, I gotta read the questions better.

Perimeter not area.

diagonal length = √((28 - 12)² + (24 - 10)²) = 21.26

P = 12 + 10 + 28 + 24 + 21.26 = 95.26 units

sphere surface area = 4πR²

R = √(379.94 / 4(3.14) = 5.5 in

D = 2R = 11 inch

The mean per capita income is 15,451 dollars per annum with a variance of 298,116. What is the probability that the sample mean
docker41 [41]

Answer: 0.5467

Step-by-step explanation:

Let X be the random variable that represents the income (in dollars) of a randomly selected person.

Given : \mu=15451

\sigma^2=298116\\\\\Rightarrow\ \sigma=\sqrt{298116}=546

Sample size : n=350

z-score : \dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}

To find the probability that the sample mean would differ from the true mean by less than 22 dollars, the interval will be

\mu-22,\ \mu+22\\\\=15,451 -22,\ 15,451 +22\\\\=15429,\ 15473

For x=15429

z=\dfrac{15429-15451}{\dfrac{546}{\sqrt{350}}}\approx-0.75

For x=15473

z=\dfrac{15473-15451}{\dfrac{546}{\sqrt{350}}}\approx0.75

The required probability :-

P(15429

Hence, the required probability is 0.5467.
