It is known that for all tests administered last year, the distribution of scores was approximately normal with mean 74 and sta

Lunna [17]

Answer: 19.77%

Step-by-step explanation:

Given: Mean : $\mu=74$

Standard deviation : $\sigma = 7.1$

The formula to calculate z-score is given by :_

$z=\dfrac{x-\mu}{\sigma}$

For x= 80, we have

$z=\dfrac{80-74}{7.1}\approx0.85$

The P-value = $P(z>0.85)=1-P(z$

In percent , $0.1976626\times100=19.76626\%\approx19.77\%$

Hence, the approximate percentage of the test scores during the past year exceeded 80 =19.77%

Matt was given the problem: "16 is 80% of what?"

irga5000 [103]

Answer:

$\frac{16}{x} = \frac{80}{100}$

Step-by-step explanation:

To set up this proportion, we know that 16 must correspond with 80% and the x, the number we're looking for must correspond with 100%

$\frac{16}{x} = \frac{80}{100}$

This would be the correct proportion, and you could simplify it to equal

$\frac{16*100}{80}$

You need to subtract the largest number and the smallest, so it would be 12-0, getting an answer of 12.
