A tire company finds that the lifespan for one brand of its tires is normally distributed with a mean of 47,500 miles and a stan
Illusion [34]

Answer:

42580 miles

Step-by-step explanation:

Mean = \mu = 47500

\sigma = 3000

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

P(X\leq x)=5\%

P(\frac{x-\mu}{\sigma}\leq \frac{x-47500}{3000})=0.05

By using normal table values :

\frac{x-47500}{3000}=-1.64

x=(-1.64 \times 3000)+47500

x=42580

Hence the approximate number of miles for the warranty is 42580 miles

What Value of X satisfies this equation?
Salsk061 [2.6K]

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 to this question
Darina [25.2K]

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.
