Answer:
0.245
Step-by-step explanation:
In order to find find the probability that the mean of the groups age is between 90 and 100 months, we have to find z for each value
Z = (x – mean)/standard deviation
Le x be the average age of a vehicle
Z1 = (90 – 96)/16 = -0.375
Z2 = (100 – 96)/16 = 0.25
Then we use the z table to find the area under the curve.
Area for Z1 = 0.354
Area for Z2 = 0.599
The probability that the mean of the groups age is between 90 and 100 months can be found as follows:
0.599 – 0.354 = 0.245
Answer:
5/7 hours per birdhouse
Step-by-step explanation:
If you want "hours per birdhouse", divide the number of hours by the number of birdhouses. ("Per" essentially means "divided by" in this context.)
(5 hours)/(7 birdhouses) = (5/7) hours/birdhouse
Answer:
<u>The correct answer is D. h(x) = 7x – 4x2 – 11x – 17</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
f(x) = 7x – 8x – 2
g(x) = 4x2 + 3x + 15
2. Which of the following answers shows the difference in the amounts of water released, h(x) = f(x) – g(x)?
h(x) = f(x) - g(x)
h(x) = 7x – 8x – 2 - (4x2 + 3x + 15)
h(x) = 7x – 8x – 2 - 4x2 - 3x - 15
h(x) = 7x – 11x – 17 - 4x2
<u>The correct answer is D. h(x) = 7x – 4x2 – 11x – 17</u>
