Answer:
0.964
Step-by-step explanation:
It's easier to approach this problem if you find the prob. that z is less than -1.8 and then subtract your result from 1.00.
The prob. that z is less than -1.8 can be found using any calculator with probability and statistic functions.
The prob. that z is less than -1.8 = normcdf(-100,-8) = 0.036. Here "cdf" stands for "cumulative probability density function)," -100 is far to the left of z = -1.8, and the result (0.036) is the area under the standard normal probability density curve to the left of z = -1.8.
Finally, subtract this 0.036 from 1.000, obtaining 0.964. This is the probability that z is greater than -1.8.
You should ask your classmates for the answers
Simple....
you have:
5x+2=4x-9
5x+2=4x-9
-4x -4x
x+2=-9
x+2=-9
-2 -2
x=-11
Thus, your answer.
A scale model of this scooter would be 4 and 2/3 inches long.
