8 0

Answer:

There were 120 questions on the test.

Step-by-step explanation:

It is given that:

Number of questions answered = 54

Grade percent = 45%

Let,

x be the total number of questions

45% of x = 54

\frac{45}{100}x=54\\0.45x = 54

Dividing both sides by 0.45

\frac{0.45x}{0.45}=\frac{54}{0.45}\\x=120

Therefore,

There were 120 questions on the test.

Answer:

Less than 264.44 days would be for the shortest 20%

Step-by-step explanation:

Given that X, the length of a human pregnancy is normally distributed with a mean of 272 days with a standard deviation of 9 days (Bhat & Kushtagi, 2006).

X is N(272, 9)

Corresponding Z score would be for any x

z=\frac{x-272}{9}

We have to find out the shortest 20%

Corresponding z score i.e. z score 20th percentile is given by

-0.84

corresponding x score is

272-0.84*9\\= 264.44

Less than 264.44 days would be for the shortest 20%
