Help please!!! I don’t understand this question

Mathematics
1 answer:
Elenna [48]3 years ago

Answer:

C

Step-by-step explanation:

Let us first write an equation. Using the SOHCAHTOA rule, we should know that the tangent of an angle equals it's \frac{opposite}{adjacent}. The opposite of our given 20° angle is 9, and the adjacent side is <em>x</em>.

tan(20°)=\frac{9}{x}

0.364=\frac{9}{x} \\x=\frac{9}{0.364}\\x=24.7

<u>C</u>

I am having trouble solving for Y. I solved for X in the second equation, but I cannot seem to figure it out by substituting for
kumpel [21]
X - 2y = -10 -->   x = 2y -10

3x + 5y = 25 --> 3(2y-10) + 5y = 25 --> 11y - 30 = 25 --> 11y = 55 --> y = 5

x = 2y -10 --> x = 2(5) -10 --> x =10 -10 --> x =0

Hi!

1. Your answer should be the first option. (It looks the best to me)

2. it is the last option because it's the only one that's identical to the original picture.

3. It should be the third option since there are 10cm on the top of the shape.

4. a total of 39

Hope that helps, good luck! :)

Answer:

A.

Sample 1 mean: 6.375

Sample 2 mean: 6.375

Sample 3 mean: 6.625

B.

Range of sample means: 0.25

C.

The first and last boxes should be checked, as they are true.

Step-by-step explanation:

To calculate the mean you must add all of the numbers together and then divide the sum by the quantity of numbers. Ex: 3+7+8+3+7+9+6+8 = 51.

51/8 = 6.375.
