Math question.......................................
ValentinkaMS [17]
Question 1:

The answer is A: Sam.

His table is the only one that follows the conditions set in the question. 

Question 2:

Choosing two points; (0, 14) and (4, 10)

Slope (m) = \frac{10 - 14}{4 - 0} =  \frac{-4}{4} = -1

Thus, equation, 

y -  y_{1} = m(x -  x_{1})  

y - 10 = -1(x - 4)

y = -x + 14

I'm getting that for my equation of the line, so my best guess is that the answer is C.

The reason I got my answer is probably because I made a calculation mistake somewhere. If you use my methods, you should arrive at the correct answer.

The answer is C. ( I believe )

cluponka [151]

Answer:

  • y = - (x - h - 3)² - k + 7

Step-by-step explanation:

<u>Let the patent function be:</u>

  • y = (x - h)² + k in the vertex form

<u>Then transformation steps are:</u>

1. Reflection over x- axis, y' = -y

  • y' = - (x - h)² - k

2. Translation 7 units up and 3 units to the right, y'' = y' + 7, x' = x - 3

  • y'' = - (x - h - 3)² - k + 7

The prices of three t-shirts styles are $24, $30 and $36. the probability of choosing a $24 t-shirt is 1/6. the probability of c
Slav-nsk [51]

\text{Answer} : \text{The expected value of a t-shirt is \$31.}

Explanation:

Since we have given that

The prices of three t-shirts styles  i.e $24, $30, $36 with their probability is given by

\frac{1}{6}, \frac{1}{2},\frac{1}{3}

As we know that,

E(X)= \sum_{1}^{3}x_iP(x_i)

\text{where} x_i \text{ is the prices of t- shirts styles}

Now,

x_1= \$24 , x_2=\$30 , x_3=$36

and

P(x_1)=\frac{1}{6},P(x_2)=\frac{1}{2}, P(x_3)=\frac{1}{3}

So,

E(X)= 24\times \frac{1}{6}+30\times\frac{1}{2}+36\times \frac{1}{3}\\=4+15+12\\=31

So, the expected value of a t-shirt = $31.
