42580 miles
Step-by-step explanation:
Mean = 

The manufacturer does not want to replace more than 5% of the tires


By using normal table values :



Hence the approximate number of miles for the warranty is 42580 miles
345/8 is the another one yes
Answer:
x=0
Step-by-step explanation:
4 ( 2.5) ^x = 4
Divide each side by 4
4/4 ( 2.5) ^x = 4/4
( 2.5) ^x = 1
Take the log of each side
log ( 2.5) ^x = log (1)
x log ( 2.5) = log 1
x log (2.5) = 0
Divide each side by log (2.5)
x = 0
Answer: The height of the rectangle is 8 centimeters (cm)
How?
A(rea) = B(ase) × H(eight)
Since the question gives us the formula (A = B × H), area (120 cm), and base (15 cm), it fills in some parts of the equation.
So really:
120 = 15 × H <-- This is the formula, but some parts are filled in
Which can be rearranged as:
H = 120 ÷ 15 <-- Solve this
H = 8
Hope this helps.
