Answer:

y = 2x - 8

Step-by-step explanation:

Since you have the slope of the line and point that the line passes through, you can use "point-slope form", hence the name.

Point-slope form is: $y-y_1=m(x-x_1)$

Substitute the slope (2) into m, and substitute the x-value of the point into $x_1$ and the the y-value of the point into $y_1$ .

$y-(-4)=2(x-(2))$

Simplify this equation.

$y+4=2(x-2)$

Distribute 2 inside the parentheses.

$y+4=2x-4$

Subtract 4 from both sides.

$y=2x-8$ is the final answer.

Answer:

43. I'm not really sure about this one but here's what I got:

The average height of a 4th grader is 58 inches. (Maybe that'll help) Also if it's by the number of kids in the class....I would assume that there are at most 33 kids in the class....I'm not sure what it's asking...sorry :(

46. There are 8 total marbles so if you were selecting a green marble the probability of getting a green marble would be 3/8. If there are 2 blue marbles then the probability would be 2/8 or 1/4

48. In a deck of cards there are 26 black cards and 26 red cards. Number of event occurrences. Total number of trials. For example, if a dice is rolled 6000 times and the number '5' occurs 990 times, then the experimental probability that '5' shows up on the dice is 990/6000 = 0.165. That should help with this one

49. Since there are 6 sides and each side is a number 1-6, the probability of rolling a six is 1:6

50. This one is easy if you read the question right. There are no pink marbles....

I'm not that great with graphs

I hope this helped a little....some of the questions I didn't understand.

Suppose the claim size of an auto collision insurance, X, is uniformly distributed on the interval $1,000 to $10,000. What is th

timurjin [86]

Answer:

35.35%

Step-by-step explanation:

If there were no deductibles, the expected claim payment would be:

$E(X) = \frac{10,000 +1,000}{2} \\E(X) =\$5,500$

If the collision insurance claim is under $2,000, then the insurer would not pay anything, but if X > $2,000, then the insurer would pay X - $2,000. The new expected value is:

$E_2(X)=\frac{2,000-1,000}{10,000-1,000} *0+\frac{10,000-2,000}{10,000-1,000}*\frac{(2,000-2,000)+(10,000-2,000)}{2} \\E_2(X)=\frac{8}{9}*\frac{0+8,000}{2}\\ E_2(X)=\$3,555.56$

The percentage reduction on the claim payment is:

$P=(1-\frac{E_2(X)}{E(X)})*100 \\P=(1-\frac{3,555.56}{5,500})*100\\P=35.35\%$

There was a 35.35% reduction.

frutty [35]

Answer:

18 Feet

Step-by-step explanation:

For every 1 inch, the building is 2 feet

There are 9 inches in the building

The equation would be 9 * 2 = 18
