The gas mileage for a certain model of car is known to have a standard deviation of 6 mi/gallon. A simple random sample of 49 ca
lord [1]

Answer:

The answer is "(27.030,29.770)"

Step-by-step explanation:

(\bar{x}) = 28.4

(n)= 49

(\sigma) = 6

(CI) = \bar{x}\pm z^*_{\frac{\alpha}{2}} \frac{\sigma}{\sqrt{n}}

z^*_{\frac{\alpha}{2}}\ for \ 89\%\ confidence = 1.598 \\\\\text{Using z table }\\\\ NORM.S.INV(1-\frac{(1-0.89)}{2})

CI = 28.4 \pm 1.598 \times  \frac{6}{\sqrt{49}}=(27.030,29.770)

Answer:

the 1st, 2nd and 6th statements are true.

and probably the 3rd statement is true.

I am not sure about the 3rd statement, as I cannot read the original in your screenshot, and your transcribed description is probably not correct and contains typos.

but all you need is in the explanation below to decide, if the actual 3rd statement is true or not.

if "58 + 79 = 1268" actually means "5s + 7g = 1268" then it is true. otherwise it is false.

Step-by-step explanation:

g = number of general tickets sold

s = number of student tickets sold

so, in total

g + s = 234

tickets were sold.

and the revenue was

7g + 5s = $1,268

out of these 2 basic equating we get

g = 234 - s

and then

7(234 - s) + 5s = 1,268

1,638 - 7s + 5s = 1,268

-2s = -370

s = 185

g = 234 - s = 234 - 185 = 49

so, we know

185 student tickets were sold for 5×185 = $925

49 general tickets were sold for 7×49 = $343

Write <br> 9/12<br> in simplest form.
Yuri [45]
9/12 in simplest form would be 3/4 because you divide bothe 9 and 12 dived by three because what you do to the denominator you do to the nominator so after you divide 9/12 by 3 you would have 3/4 which 3/4 is 9/12 in simplest form
