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:
4x - 3y = 36
Step-by-step explanation:
2/3x - 1/2y = 6
Multiply each side by 6 to get rid of the fractions
6* (2/3x - 1/2y) = 6*6
Distribute the 6
12/3 x - 6/2y = 36
4x -3y = 36
Answer:
<em>8 jars</em>
Step-by-step explanation:
Divide 2/3 by 1/12.
(2/3) / (1/12) = 2/3 * 12/1 = 24/3 = 8
