Answer:
first choice
Step-by-step explanation:
There are 34 composite numbers between 1 to 50 which are as follows: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50.
The surface area is A≈96ft²
Y = 50x
Since every minute he jumps 50 times, we multiply 50 by the amount of minutes (x)
it would be 10/5 or 2
y2-y1/x2-x1
17-7/9-4
10/5 simplify
2
0.321 is the probability that their mean printing speed of the sample is greater than 17.99 ppm.
We are given the following information in the question:
Mean, μ = 17.39 ppm
Standard Deviation, σ = 4.25 ppm
Sample size = 11
We are given that the distribution of printing speed is a bell shaped distribution that is a normal distribution.
Formula:
P(printing speed of the sample is greater than 17.99 ppm.)
P(x > 17.99)
Calculating the value from the standard normal table we have,
Thus, 0.321 is the probability that their mean printing speed of the sample is greater than 17.99 ppm.
