Alenkasestr [34]2 years ago

Answer:

The  value is  1.75 \  and  \   -1.75

Step-by-step explanation:

From the question we are told that

     The null hypothesis is  H_1 :  \mu \ne 3.24

     The level of significance is  \alpha = 0.08

From the z table  the critical value of  \alpha considering the two tails of the normal  curve( This is because this a two tailed test ) is

       z= \pm  1.75

Hence the critical value is  

       1.75 \  and  \   -1.75

A.
1hr \: 15min = 75min

c = 0.22t = 0.22 \times 75 = 16.5

cost is $16.50

B.

26.40 = 0.22 \times t

rearrange to solve for t:

t = \frac{26.40}{0.22} = 120min

C. This is the same as part B, only the rate changed

t = \frac{26.40}{0.25} = 105.6min

they ask for the greatest number of minutes, so we round down (take the floor of the value).

the answer is 105 minutes.

Using these coordinates, find the slope. (0, -6), (3, -2)
seropon [69]

Answer:

The slope between the points (0, -6) and (3, -2) will be:

  • m=\frac{4}{3}

Step-by-step explanation:

Given the points

  • (0, -6)
  • (3, -2)

The slope between the points (0, -6) and (3, -2) will be:

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(0,\:-6\right),\:\left(x_2,\:y_2\right)=\left(3,\:-2\right)

m=\frac{-2-\left(-6\right)}{3-0}

m=\frac{4}{3}

Therefore, the slope between the points (0, -6) and (3, -2) will be:

  • m=\frac{4}{3}

Store A sells 12 juice bottles for $4 and store B sells 18 juice bottle for $6. Are the rates equivalent? explain your reasoning
mamaluj [8]

Answer:

Yes!

The rate can be expressed by the ratio 3:1

For every 3 bottles, its $1

For every 6 bottles, its $2

For every 12 bottles its $4

and for every 18 bottles its $6

The juice's are equivalent because the ratio of number to bottles to dollars is equal.
