4/9 of students at a school are boys. If there are 2601 students at the school, how many are girls?

stira [4]

Answer:

1156

Step-by-step explanation:

First you get the answer you divide by 9 since it is the denominator and ultimately means how many "pieces" or parts the whole number or amount will be in. You divide by 9 and get 289. Now you have the 1/9 part of 2601. You now multiply this number by 4 to get the 4/9 of 2601. Whennyou multiply by four you get 1156. I hope this makes sense and that it helps you. Please mark brainliest if it did help. :)

A police officer claims that the proportion of accidents that occur in the daytime (versus nighttime) at a certain intersection

Roman55 [17]

Answer: -1.78

Step-by-step explanation:

As per given description, we have

Population proportion : $p=0.35$

Sample size : n= 500

Sample proportion : $\hat{p}=\dfrac{156}{500}=0.312$

Test statistic for population proportion :-

$z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}\\\\\\=\dfrac{0.312-0.35}{\sqrt{\dfrac{0.35(1-0.35)}{500}}}\\\\=-1.78146747757\ \ \text{(Simplified)}\\\\\approx-1.78$
