Find the slope of the line that passes through (-2 1) (1 10)

Mathematics

sweet-ann [11.9K]3 years ago

Answer:

3

Step-by-step explanation:

We can find the slope using the equation y2-y1/x2-x1=m. So first, we want to subtract 1 from 10, which is 9.

Then, we subtract -2 from 1, which turns into 1+2, or 3. Then divide 9 by 3, which is 3. The slope is 3.

Hope this helps!

In any​ year, the weather can inflict storm damage to a home. From year to​ year, the damage is random. Let Y denote the dollar
krok68 [10]

Answer:

a. mean = 1000

standard deviation = 4358.9

b. expected value of average damage bar Y = 1000

probability bar y exceeds 2000 = 0.011

Step-by-step explanation:

we have p1 = 95%, y1 = 0, p2 = 5%, y2 = 20000

Mean = (0.95 * 0) + (0.05 * 20000)

= 1000

var(y) = E(y²) - E(Y)²

= we solve for E(y)²

= 0²*0.95 + 20000²*0.05

= 0 + 20000000

then the variance of y = 20000000 - 1000²

=20000000-1000000

= $19000000

standard  deviation is the square root of variance

= √19000000

= 4358.9

2.

a. Expected value of average is also the mean = 1000

b. we are to find probability that barY exceeds 2000

z=\frac{2000-1000}{\sqrt{19000000/100} }

= 1000/435.889

= 2.29

1-p(z≤2.29)

= 1 - 0.989

= 0.011

so the probability that barY exceeds 2000 is 0.011
