What's the value of x
(3x-5) and (x+10)

Answers

3x-5+x+10+x=180 (property of a triangle (angles add up to 180°))
5x+5=180 (simplify)
5x=175 (subtraction property of equality)
x=35 (division property of equality)

Therefore, x is equal to 35.

What is the median of this set of data?

362, 187, 211, 298, 331, 250, 347, 199

Answers

Answer:

274

Step-by-step explanation:

Hey There!

So if you didnt know the median is the middle number ( in value) of the set

So first we would like to arrange the numbers in order from least to greatest

187 , 199 , 211 , 250 , 298 , 331 , 347 , 362

Then we take the middle number(s)

if there is just one then that is the answer but if there is two than we add them together and divide that by 2

In this case there are two which would be 250 and 298

So we add them together

250+298=548

Then we just divide that by 2

[tex]\frac{548}{2} =274[/tex]

Therefore the median is 274

If YV = 28 in, find the length of the major arc VYX. Round to the nearest tenth ( one decimal place).

Answers

Answer:

[tex]VYX=84.3in[/tex]

Step-by-step explanation:

Given

[tex]YV = 28in[/tex]

[tex]\angle WZX = 15^\circ[/tex]

See attachment

Required

Determine the length of [tex]VYX[/tex]

First, calculate the major angle VZX

[tex]\theta = \angle VZX = 360 - \angle WZX[/tex]

[tex]\theta = \angle VZX = 360 - 15[/tex]

[tex]\theta = \angle VZX = 345[/tex]

[tex]\theta = 345[/tex]

The length of arc VYX, is:

[tex]L=\frac{\theta}{360} * 2\pi r[/tex]

Where

[tex]r = \frac{1}{2} * Diameter[/tex]

[tex]r = \frac{1}{2} * YV[/tex]

[tex]r = \frac{1}{2} * 28[/tex]

[tex]r = 14[/tex]

So:

[tex]L=\frac{\theta}{360} * 2\pi r[/tex]

[tex]L=\frac{345}{360} * 2 * \frac{22}{7} *14[/tex]

[tex]L=\frac{345}{360} * 2 * 22 *2[/tex]

[tex]L=\frac{345* 2 * 22 *2}{360}[/tex]

[tex]L=\frac{30360}{360}[/tex]

[tex]L=84.3in[/tex]

Hence, the length of VYX is:

[tex]VYX=84.3in[/tex]

Compare the areas. What is the ratio of the areas? SHOW YOUR WORK

Answers

Answer:

Ratio of the area of MIKE to TEAM = 9 : 1

Step-by-step explanation:

Ratio of similar shapes = square of the ratio of their corresponding sides

Since TEAM ~ MIKE, therefore the ratio of their areas = square of the height of MIKE : square of the height of TEAM

Ratio = 33² : 11²

Ratio = 1089 : 121

Ratio = 9 : 1

B)

0: =0.50

C)

0: =0.55

: ≠0.55

D)

: >0.55

Answer is:
B

Answers

Answer:

[tex]H_{0} = 0.5[/tex]

[tex]H_{a} > 0.5[/tex]

Option b

Step-by-step explanation:

Researchers conducted a study to determine whether the majority of community college students plan to vote in the next presidential election.

The null hypothesis is always an equalityu related to the expected, or tested value. In this question, the tested value is half of the students, a proportion of 0.5, that is: [tex]H_{0} = 0.5[/tex]

The alternate hypothesis is related to the test we are taking. In this question, we are testing if the majority of the students plan to vote, that is, if the proportion of the students that plan to vote is higher than 0.5. So [tex]H_{a} > 0.5[/tex]

So the correct answer is given by option B.

b) No

Answers

Answer:

a) Yes

Step-by-step explanation:

Because, 3+7=10

Answer: yes

Explanation: In this problem, to determine whether c = 3

is a solution to the equation, we substitute 3 in for c.

So we have (3) + 7 = 10.

Simplifying the left side of the equation, (3) + 7 is 10.

So we have 10 = 10 which is a true statement so our answer is yes.

Answer:

#8 - 52°, #9 - 29°

Step-by-step explanation:

8. The two angles added together are a straight line, so they sum up to 180 degrees.

x + (2x + 24°) = 3x + 24° = 180°

3x + 24° = 180°

3x = 156°

x = 52°

9. Similar to #8. "Supplementary" means they add up to 180° (whether they are actually next to each other or not).

So,     4x + (2x + 6°) = 180°

                 6x + 6° = 180°

                     6x = 174°

                        x = 29°
