Answer:
Step-by-step explanation:
Let X be the diameter of bolts produced in a machine shop
X is normal with mean = 6.46 mm and std dev = 0.05 mm.
We are to find the two diameters that separate the top 9% and the bottom 9%.
We can use std normal distribution value for this and from Z we can calculate X values
P(Z<z) = 0.09 and P(Z<z1) = 0.91
z=-1.341 and z1 = +1.341
Corresponding X values would be
for bottom 9%
X = 6.46-1.341*0.05 = 6.39295
X = 6.46+1.341*0.05=6.52305
H= 13
This is because -117/ -9 equals 13
Answer:
Given:
- A shopper buys a $100 coat on sale for 20% off.
- An additional $5 is taken off the sale price by using a discount coupon.
- A sales tax of 8% is paid on the final selling price.
To find:
- The total amount the shopper pays for the coat.
The formula used to calculate percentage is:(value/total value)*100%.
Step-by-step explanation:
Step 1 of 2
After the 20% sale, the coat costs
100*0.8 = 80 dollars.
Then 5 dollars are taken off for a cost of
80-5 = 75
Step 2 of 2
Now adding on the sales tax,
the final amount is 75(0.8) = 81 dollars
-28+28=0, and you add 38. 38 degrees.
