Answer:
0.018 is the required probability.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 60,000 miles
Standard Deviation, σ = 1500 miles
We are given that the distribution of tread life is a bell shaped distribution that is a normal distribution.
Formula:
P(brand will last between 56,850 miles and 57,300 miles)
0.018 is the probability a certain tire of this brand will last between 56,850 miles and 57,300 miles.
Because the unit rate for a pound of grapes is 1.99, the expression would be:

Step-by-step explanation:
if u times them all up first u get 60 times 11 witch = 660 and then i times 660 and 8 to get 5280
The cost of the printer is $309 and cost of the computer is $618.
Step-by-step explanation:
Let x denote the cost of computer
Let y denote the cost of printer
Total cost of printer and computer OR
x + y = $927
<u>To find the cost of x and y,</u>
Cost of computer = 2 x cost of the planet
x = 2y
x+y = 927
2y+y = 927
3y = 927
y = 309
x = 2y
x = 2(309)
x = 618
Therefore, the cost of the printer is $309 and cost of the computer is $618.
