Answer:

20 days

Step-by-step explanation:

Subtract 1.5 gallons from 14 gallons to obtain the number of days the car will run without the warning light going on:  12.5 gallons.

Dividing this result by 0.6 gallons/day, we get

 12.5 gal

------------------- = 20.82 days.  Round this down to 20 days.  (We're not

 0.6 gal/day                                dealing in partial days.)

Triangles= 180°

Add the 3 angles to equal 180°


17x + (10x - 5) + 50= 180
combine like terms

27x + 45= 180
subtract 45 from both sides

27x= 135
divide both sides by 27

x= 5


ANSWER: x= 5

Hope this helps! :)

Can the three angles 25 65 and 90 create one unique triangle
Serhud [2]

Answer:

Yes, it can. Triangles [in order for them to be one] must equal 180. If you add all of these angles together, since a triangle only has three angles anyway, it equals to 180, so you know it's a triangle.

If this was confusing, I am happy to help further!

miskamm [114]

Answer:

D. We are 95% confident that between about 22% and 28% of ESPN Viewers thought the Eagles would still win the division.

Step-by-step explanation:

We have to calculate a 95% confidence interval for the population proportion.  The population is made up of ESPN viewers.

The sample proportion is p=0.25.

The standard error of the proportion is:

\sigma_p=\sqrt{\dfrac{p(1-p)}{n}}=\sqrt{\dfrac{0.25*0.75}{914}}\\\\\\ \sigma_p=\sqrt{0.00021}=0.014

The critical z-value for a 95% confidence interval is z=1.96.

The margin of error (MOE) can be calculated as:

MOE=z\cdot \sigma_p=1.96 \cdot 0.014=0.028

Then, the lower and upper bounds of the confidence interval are:

LL=p-z \cdot \sigma_p = 0.25-0.028=0.222\\\\UL=p+z \cdot \sigma_p = 0.25+0.028=0.278

The 95% confidence interval for the proportion of ESPN viewers  is (0.222, 0.278) or (22.2%, 27.8%).
