Hello there! The missing y-values are 12, 14, and 16.

Given all our x-values and two additional y-values, we can see that multiplying the x-value by 2 gives us the y-value. This is shown when x is 5 and 9, because multiplying 5 by 2 gave us 10, and multiplying 9 by 2 gave us 18. Because of this rule, we can multiply each given x-value by 2 to receive our y-value. Once solving, we also notice that the y-values all add by 2 to get the next factor as the data number increases. Hope this helps!

densk [106]

Hey there! :) So first of all, I got 31.67 per second. The way I got my answer is first, I knew that 1 KM is 1000 Meters. So now, I multiplied 114 x 1000 which equals 114,000 Meters. Then, I figured out that 1 Hour has 3600 Seconds. Then I did 114,000 ÷ 3,600 and got 31.67 Seconds. And that is how I got the answer!

Hope it helps and it's the right answer & it's understandable! :D

Monica [59]

Answer:

0.3085,0.2417,0.0045

Step-by-step explanation:

Given that X, the amount of money spent at shopping centers between 4 P.M. and 6 P.M. on Sundays has a normal distribution with mean $85 and with a standard deviation of $20.

X is N(85, 20)

To convert into std normal variate we use the following formula

Z=\frac{x-85}{20}

a) the probability that he has spent more than $95 at the mall

=P(X>95) = P(Z>0.5)=\\0.5-0.1915\\=0.3085

b.  the probability that he has spent between $95 and $115 at the mall

=P(95

c. If two shoppers are randomly selected, what is the probability that both shoppers have spent more than $115 at the mall

=product of two probabilities since independent

= {P(X>115)}^2\\= P(Z>1.5)*P(Z>1,5)\\= 0.0668^2\\=0.0045

Write the standard form of the line that contains a y-intercept of -3 and passes through the point (3,0). Include your
Ymorist [56]

Answer:

y = -3x + 9 is your answer.

Step-by-step explanation:

So your y-intercept is the slope. Here is the equation we are going to use:

y - y_1 = m(x - x_1)

y_1 = 0

x_1 = 3

m = -3.

y - 0 = -3(x - 3)

y - 0 = -3x + 9

y = -3x + 9 is your answer.
