A manufacturer knows that their items have a normally distributed lifespan, with a mean of 5.8 years, and standard deviation of
fenix001 [56]

Answer:

3.6 years

Step-by-step explanation:

Using the standard normal probability distribution table, we obtain the Zscore which is 10% to left of the distribution.

The Zscore gives, - 1.282

To obtain the number of years, let this be x ;

Recall, the Zscore formula :

Zscore = (x - μ) / σ

x = number of years

μ = 5.8

σ = 1.7

Zscore = (x - μ) / σ

-1.282 = (x - 5.8) / 1.7

-1.282 * 1.7 = x - 5.8

-2.1794 = x - 5.8

-2.1794 + 5.8 = x

x = 3.6206

x = 3.6 years

Veseljchak [2.6K]

Answer:

1.05 cm = 75 cm

Step-by-step explanation:

First, convert 45 meters into centimeters. You will get 4500 centimeters. Then, convert the numbers into a fraction form (126/4500). Divide the numerator and denominator by 15 to get 4.2/300. If you then divide them both by 4 you will get 1.05/75. This means that every 1.05 cm on the paper represents 75 cm of the real life lot.
