Option a: multiply \frac{2}{5} by 4.

Explanation:

The expression is \frac{2}{5} \div \frac{1}{4}

Dividing the two fractions which is the same as multiplying the first fraction by the reciprocal value of the second fraction.

Hence, it can be written as

\frac{2}{5} \times \frac{4}{1}=\frac{8}{5}

Hence, \frac{8}{5} is the quotient.

Option a: multiply \frac{2}{5} by 4.

To determine the quotient, let us multiply the term \frac{2}{5} by 4, we get,

\frac{2}{5} \times 4=\frac{8}{5}

Hence,  \frac{8}{5} is the quotient.

Thus, Option a is the correct answer.

Option b: multiply \frac{2}{5} by \frac{1}{4}

To determine the quotient, let us multiply the term \frac{2}{5} by 4, we get,

\frac{2}{5} \times \frac{1}{4}=\frac{1}{10}

\frac{1}{10} is not the quotient. Since, the quotient is \frac{1}{10} which is not equivalent to \frac{8}{5} and hence we cannot multiply \frac{2}{5} by \frac{1}{4}

Hence, Option b is not the correct answer.

Option c: multiply \frac{5}{2} by \frac{1}{4}

To determine the quotient, let us multiply the term \frac{5}{2} by \frac{1}{4}, we get,

\frac{5}{2} \times\frac{1}{4}=\frac{5}{8}

\frac{5}{8} is not the quotient. Since, the quotient is \frac{5}{8} which is not equivalent to \frac{8}{5} and hence we cannot multiply \frac{5}{2} by \frac{1}{4}

Hence, Option c is not the correct answer.

Option d: multiply \frac{5}{2} by 4

To determine the quotient, let us multiply the term \frac{5}{2} by 4, we get,

\frac{5}{2} \times4=10

10 is not the quotient. Since, the quotient 10 which is not equivalent to \frac{8}{5} and hence we cannot multiply \frac{5}{2} by 4.

Hence, Option d is not the correct answer.

A rental car company claims the mean time to rent a car on their website is 60 seconds with a standard deviation of 22 seconds.
Gelneren [198K]

Answer:

Since the calculated value of Z does not fall in the critical region we accept our null hypothesis that mean = 60 seconds

Step-by-step explanation:

State the null hypothesis

H0: u = 60against the claim

Ha u≠   60   (this is a two tailed test)

Sample size n= 36

Sample mean=X`= 55

Population mean = u= 60

The significance level α = 0.05

Standard deviation= Sd = 22 seconds

Z= X`- u / Sd /√n

Z= 55- 60 / 22/√6

z= - 5/22/6

Z= -1.3635

The value of z from the table is Z∝/2= ±1.96

The critical region is less than - 1.96 and greater than 1.96.

Since the calculated value of Z does not fall in the critical region we accept our null hypothesis that mean = 60 seconds
