Answer: The number of different combinations of 2 vegetables are possible = 15 .

Step-by-step explanation:

In Mathematics , the number of combinations of selecting r values out of n values = $^nC_r=\dfrac{n!}{r!(n-r)!}$

Given : Number of available vegetables = 6

Then, the number of different combinations of 2 vegetables are possible will be :

$^6C_2=\dfrac{6!}{2!(6-2)!}=\dfrac{6\times5\times4!}{2\times4!}=15$

Hence , the number of different combinations of 2 vegetables are possible = 15 .

The time at which the mailman delivers the mail to ace bike shop follows a normal distribution with mean 2:00 pm and standard de

ivolga24 [154]

There are three questions related to this problem.

First, the probability of the mail will arrive after 2:30 PM

Find the z-score of 2:30 which is 30 minutes after 2:00.

z(2:30) = (2:30 – 2:00)/15 = -30/15 = -2

P(x < 2:30) = P(z<-2) = 0.0228

Second, the probability of the mail will arrive at 1:36 PM

Find the z-score of 1:36 which is 24 minutes before 2:00.

z(1:36) = (1:36 – 2:00)/15 = -24/15 = -1.6

P(x < 1:36) = P(z<-1.6) = 0.0548

Lastly, the probability of the mail will arrive between 1:48 PM and 2:09 PM

Find the z-score of 1:46 and 2:09 PM which will result to a z value of 0.034599

P(1:48 < x < 2:09) = P(z<0.034599) = 0.5138

Toyota advertises that their Toyota Highlander Hybrid provide 28 MPG. To test this, an experiment involving a sample of 20 Toyot

klemol [59]

Answer:

We accept the null hypothesis.

Step-by-step explanation:

We are given the following in the question:

Sample mean, $\bar{x}$ = 28.8 miles per gallon

Sample size, n = 120

Alpha, α = 0.01

Sample standard deviation, σ = 6.89 miles per gallon

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 28\text{ miles per gallon.}\\H_A: \mu \neq 28\text{ miles per gallon.}$

We use Two-tailed t test to perform this hypothesis.

Formula:

$t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n-1}} }$

Putting all the values, we have

$t_{stat} = \displaystyle\frac{28.8 - 28}{\frac{6.89}{\sqrt{19}} } = 0.5061$

Now, $t_{critical} \text{ at 0.01 level of significance, 19 degree of freedom } =\pm 2.8609$ Since,

$-2.609 < t_{stat} < 2.8609$

We fail to reject the null hypothesis and accept it.

We accept the null hypothesis and the population mean MPG of Toyota Highlander Hybrid vehicles is equal to 28 miles per gallon.
