Answer:

\huge\boxed{\sf Option \ A\ and \ C}

Step-by-step explanation:

\sf (-7)^5

The power (5) tells how many times we have to multiply the number (-7) with itself.

<u>So, it becomes:</u>

\sf (-7)*(-7)*(-7)*(-7)*(-7)

Hope this helped!

1 pint= 1/8 gallon. How many pints are there in 2/3 gallon.
FrozenT [24]

gallon = pint *0.125

gallon = pint / 8
0.125+0.125+0.125+0.125+0.125+0.125+0.125+0.125+0.125+0.125+0.125+

0.125+0.125+0.125+0.125+0.125 = 2

16 would be the answer I believe, maybe I'm wrong, double check.

7. License Plate Laws The Chapter Problem involved passenger cars in Connecticut and passenger cars in New York, but here we con
sergejj [24]

Yes it is true that commercial truck owners violate laws requiring front license plates at a higher rate than owners of passenger cars because null hypothesis is rejected.

Given among 2049 Connecticut passenger cars, 239 had only rear license plates. Among 334 Connecticut trucks, 45 had only rear license plates.

let p_{1} be the probability that commercial cars have rear license plates and p_{2} be the probability that connected trucks have rear license plates.

                         Cars                     Trucks                         Total

Total                  2049                    334                             2383

x                          239                      45                                284

p                        0.1166                   0.1347                          0.1191

α=0.05

Hypothesis will be  :

H_{0}:p_{1} =p_{2}

H_{1} :p_{1} < p_{2}

It is a left tailed test at 0.05 significance.

Standard errors of p=\sqrt{p(1-p)/n}

=\sqrt{(0.1191*0.8809)/2383}

=\sqrt{0.1049/2383}        

=0.0066

Test statistic Z=p difference/standard error

=(0.1166-0.1347)/0.0066

=-0.0181/0.0061

=-2.967

p value=0.001505<5%

Since p is less than 5% we reject null hypothesis.

We cannot calculate standard deviation so  we cannot calculate confidence interval.

Hence there is statistical evidence at 5% significance level to support that commercial truck owners violate laws requiring front license plates at a higher rate than owners of passenger cars.

15(t+2)+9t=6 Please help!
yawa3891 [41]

Answer:

t = -1

Step-by-step explanation:

15(t+2)+9t=6

15t + 30 + 9t = 6

combine like terms

24t +30 = 6

subtract 30 both sides

24t = -24

t = -1

22-5(6v-1) = -63

22- 30v + 5 = -63

27 -30v = -63

subtract both sides by 27

-30v = -90

divide it by -30

v = 3
