Answer:

The number rounded to the nearest tenth is 15.1

Step-by-step explanation:

<u>Step 1:  Make an equation</u>

When a number is decreased by 27%, the result is 11.

x * (1 - 0.27) = 11

<u>Step 2:  Solve inside the parenthesis</u>

x * (1 - 0.27) = 11

x * 0.73 = 11

<u>Step 3:  Divide both sides by 0.73</u>

0.73x / 0.73 = 11 / 0.73

x = 15.1

Answer:  The number rounded to the nearest tenth is 15.1

Answer:

15.1

Step-by-step explanation:

Decreased by 27%

100 - 27 = 73% of the original

73/100 × X = 11

X = 1100/73 = 15.06849315

University graduates have a mean job search time of 38.1 weeks, with a standard deviation of 10.1 weeks. The distribution of job
Lera25 [3.4K]

Answer:

7.1 weeks to 68.4 weeks

Step-by-step explanation:

Chebyshev's Theorem states that:

75% of the measures are within 2 standard deviations of the mean.

89% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 38.1

Standard deviation = 10.1

Between what two search times does Chebyshev's Theorem guarantee that we will find at least 89% of the graduates

Between 3 standard deviations of the mean.

So from 38.1 - 3*10.1 = 7.8 weeks to 38.1 + 3*10.1 = 68.4 weeks
