Kyung works 5 hours at a restaurant each Wednesday. He also earns $37 a week delivering newspapers. Kyung makes a total of $79.5

0 each week. If m represents the amount he makes per hour at the restaurant, which equation can be used to find the value of m?
5 m + 37 = 79.50
5 m = 79.50
37 m = 79.50
37 m + 5 = 79.50

Answer:

The answer is 5 m + 37 = 79.50

Step-by-step explanation:

You want to multiply 5 and m because m represents the amount he makes each hour and he works 5 hours each Wednesday. Then you add that to 37 to get $79.50.

A probability distribution for a random variable Y is given by P(Y=y)=cy, for y=1,2,4,5 and c is a constant. Find E(Y), the expe
Dahasolnce [82]

Answer:

c(1+2+4+5) =1

c =\frac{1}{12}

Now we can find the expected value with this formula:

E(Y) =\sum_{i=1}^n Y_i P(Y_i) =\sum_{i=1}^n cy_i *y_i = cy^2_i

And replacing we got:

E(Y) = \frac{1}{12} (1^2 + 2^2 + 4^2 +5^2) = \frac{46}{12}= \frac{23}{6}

Step-by-step explanation:

For this case we know the following probability mass function given:

P(y) = cy , y= 1,2,4,5

For this case we need to satisfy the following condition in order to have a probability distribution function:

\sum_{i=1}^n P(y_i) =1

And we have this:

c(1+2+4+5) =1

c =\frac{1}{12}

Now we can find the expected value with this formula:

E(Y) =\sum_{i=1}^n Y_i P(Y_i) =\sum_{i=1}^n cy_i *y_i = cy^2_i

And replacing we got:

E(Y) = \frac{1}{12} (1^2 + 2^2 + 4^2 +5^2) = \frac{46}{12}= \frac{23}{6}
