The owner of a video game store creates the expression −2x2 + 24x + 174 to represent the store's weekly profit in dollars, where

Semmy [17]

Answer:

$-2(x-6)^2+246$ , x = $6

Step-by-step explanation:

The expression $-2x^2+24x+174$ to represent the store's weekly profit in dollars, where x represents the price of a new video game.

Let $f(x)=-2x^2+24x+174$

We need to rewrite this quadratic function in the vertex form.

$f(x)=-2(x^2-12x)+174$

$f(x)=-2(x^2-12x+36)--2(36)+174$

$f(x)=-2(x^2-12x+36)+72+174$

$f(x)=-2(x-6)^2+246$

The equivalent expression that reveals the video game price that produces the highest weekly profit is $-2(x-6)^2+246$

and the price is $6

How to solve this for x

timama [110]

the answer is x= 10.

the steps would go like this.

4 + 3/5 × (15 + 2x) = 25

4 + 9 + 6/5x = 25

13 + 6/5x = 25

65 + 6x = 125

6x = 125 -65

6x = 60

x = 10

hope this helps

cluponka [151]

Answer:

The mean of X is 1.17.

The standard deviation of X is 1.009.

Step-by-step explanation:

The question is incomplete: 1ean and Standard Deviation of Senior Citizens In the 2010 US Census, we learn that of all people in the US 13% are senior citizens. Let the random variable X represent the number of senior citizens in a random sample of 9 people. Find the mean and standard deviation of this random variable. Enter the exact answer for the mean, and round your answer for the standard deviation to three decimal places.

This variable X can be modeled as a binomial random variable, with n=9 and p=0.13.

The mean of X is:

$\mu=np=9*0.13=1.17$

The standard deviation of X is:

$\sigma=\sqrt{npq}=\sqrt{9*0.13*0.87}=\sqrt{1.0179}=1.009$
