Answer:
2,400
Step-by-step explanation:
The number in the ten's place (5) is closer to 10 than 0, therefore the hundred's place increases to the next hundred's place.
You just add all of it. You can use a calculator.
$19.36 + $21.75 + $32.26 =
$41.11 + $32.26 =
$73.37
The answer is B. $73.37
Answer:
x = 1 and y = 4
Step-by-step explanation:
2 * 1 + 2y = 10
2 + 2y = 10
2y = 10-2
2y = 8
y = 4
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
