A drawbridge rises at a rate of 3 2/3 feet per minute. The drawbridge rises to a height of 50 feet. How long does it take the dr
k0ka [10]

Answer: Third option.

Step-by-step explanation:

You know that the drawbridge rises at a rate of 3\ \frac{2}{3} feet per minute. This means that the drawbridge rises  3\ \frac{2}{3} in a minutes.

Convert from mixed fraction to decimal number:

 3\ \frac{2}{3}\ ft=(3+0.66)\ ft=3.6\ ft

Since the drawbridge rises to a height of 50 feet, you need to apply this procedure in order to find the time the drawbridge takes to completely rise:

time=\frac{(1\ min)(50\ ft)}{3.66\ ft}=13.6\ min or 13\ \frac{7}{11}\ min

Find the​ P-value for the indicated hypothesis test with the given standardized test​ statistic, z. Decide whether to reject H0
Leviafan [203]

Answer: We do not reject the null hypothesis.

Step-by-step explanation:

  • When the p-value is greater than the significance level , then we do not reject the null hypothesis or if p-value is smaller than the significance level , then we reject the null hypothesis.

Given : Test statistic : z = -2.28

Significance level : \alpha=0.02

By using the standard normal distribution table ,

The p-value corresponds to the given test statistic ( two tailed ):-

2P(Z>|z|)=2P(Z>2.28)=0.0226

Since the p-value is greater than the significance level of 0.02.

Then , we do not reject the null hypothesis.
