Answer:
A) the probability model for the insurance company's profit:
<u>x 100 -9,900 -2,900</u>
P(X = x) 0.9975 0.0005 0.002
There is a 0.05% chance that there will be a major injury and a 0.2% chance of a minor injury, the chance of no injury happening is 99.75%.
B) the company's expected profit = ($100 x 0.9975) + (-$9,900 x 0.0005) + (-$2,900 x 0.002) = $99.75 - $4.95 - $5.80 = $89
C) the standard deviation is the square root of the variance, and the variance =
σ² = ∑(x - μ)² P(x) = (11² x 0.9975) + (9989² x 0.0005) + (2989² x 0.002) = 121 + 49,890 + 17,868 = 67,879
standard deviation = √σ² = √67,879 = 260.54
Answer:
B
Step-by-step explanation:
1) "number multiplied by -6" = number times -6 (x is the number)
-6 * x = -6x
2) "subtracted from the sum of (8 and two times the number)"
sum is addition
two times x(the number) plus 8
2x + 8
3) -6x is being subtracted from 2x + 8
2x + 8 - (-6x) =
2x + 8 + 6x =
8x + 8
B. 8x + 8
Answer: Legs
Plan: Place the right triangle in the coordinate plane with the vertex of the (a) __________ at the origin and the (b) __________ along each axis.
Question says place the right angle in the coordinate plane.
It is a right angle triangle. If we place a right angle vertex at the origin then other two sides will be along x axis and y axis.
Place the right triangle in the coordinate plane with the vertex of the right angle at the origin and the legs along each axis.
Answer:
10.368
Step-by-step explanation:
12 exponent of 4 divided by 2
Answer:
9 weeks
Step-by-step explanation:
Knowing that the "q" is the total number of quizzes, you can set the equation equal to 12, and solve for w.
12 = w + 3 Subtract 3 both sides
9 = w
