To find out how many students voted, you just add the 2 numbers up and you'll get 98. So 98 students voted.

Write an equation that you can use to solve for the height of the triangle (x). Notice that the perimeter is 48 feet.

MArishka [77]

A. 48 = 12 + 20 + x

If you use this equation then you can do 12 + 20 = 32 and then you can do 48 - 32 = 16 so x = 16

Please help I'm desperate :(

Answer:

$x=5$

Step-by-step explanation:

<u>Similar Triangles</u>

By looking at the construction of the figure, we can safely assume both triangles are similar, i.e. their internal angles are equal and their sides are proportional. Following the proportion of the heights and bases of both triangles we can set this relationship:

$\displaystyle \frac{45}{36}=\frac{5x}{20}$

Simplifying both fractions

$\displaystyle \frac{5}{4}=\frac{x}{4}$

Solving for x

$x=5$

Dvinal [7]

Answer:

b. Do not reject H0. We do not have convincing evidence that the mean weekly time spent using the Internet by Canadians is greater than 12.7 hours.

Step-by-step explanation:

Given that in a study of computer use, 1000 randomly selected Canadian Internet users were asked how much time they spend using the Internet in a typical week. The mean of the sample observations was 12.9 hours.

$H_0: \bar x =12.7\\H_a: \bar x >12,7$

(Right tailed test at 5% level)

Mean difference = 0.2

Std error = $\frac{6}{\sqrt{1000} } \\=0.1897$

Z statistic = 1.0540

p value = 0.145941

since p >alpha we do not reject H0.

b. Do not reject H0. We do not have convincing evidence that the mean weekly time spent using the Internet by Canadians is greater than 12.7 hours.

Solve these arithmetic: 2.75+0.003+0.158 =

olganol [36]

First, let's add 2.75 + 0.158. First, we add the thousandths places. Now, we have 2.758 + 0.15. Next, let's add the hundredths place. This is equal to 2.808+0.1. Finally, we have the tenths place. Now, our number is 2.908.

To finish this problem, we add 0.003. 2.908 + 0.003 = 2.911, so 2.911 is the answer to this problem.
