Find the degree measure of each angle in the triangle.

Answer:

Non-response bias also known as Participation Bias

Step-by-step explanation:

The type of bias being demonstrated in this scenario is known as Non-response bias also known as Participation Bias. This is happening in this scenario because the individuals being surveyed have gone through the trauma of a car accident and survived it. To them they are stating that seat belts would not have helped since they do not want to believe that they could have done something to prevent their injuries. This causes them to say nothing or provide false information which ultimately ruins the results of the study.

Answer:

she had 4 donuts!

Step-by-step explanation:

her total was $11.72 minus the drink so $8.60 and divided by the cost of donuts $2.15 you get 4.

Answer:

(11.72 - 3.12) ÷ 2.15 = 4

Step-by-step explanation:

You can double check by doing (2.15 x 4) + 3.12 = 11.72

Answer:

z = 7.5

Step-by-step explanation:

Polygon ABCD and polygon EFGH are similar, therefore, their sides would be proportional to each other. This means the ratio of their corresponding sides would be equal to each other.

BC corresponds to FG

CD corresponds to GH

Therefore:

8/6 = 10/z

4/3 = 10/z

Cross multiply

4*z = 10*3

4z = 30

4z/4 = 30/4

z = 7.5

Answer:

r=5

Step-by-step explanation:

25^3 = 15626

-5^3 = -125

5^3 = 125

15^3 = 3375

Answer:

R=5

Step-by-step explanation:

You first have to find the cube root

The cube root of 125 is 5

r=5

Answer:

1. 1/8 ÷ 3/4 = 1/6

2. 3/5 ÷ 3/2 = 2/5

3. 4/1 ÷ 2/3 = 6

4.9/4 ÷ 6/5 = 15/8

5.22/4 ÷ 2/5 = 261/80

Answer:

33/130

Step-by-step explanation:

3/4 - 1/5 = 11/20

5/2 - 1/3 = 2 and 1/6

11/20 divided by 13/6 = 33/130

Answer:

$2.10

Step-by-step explanation:

first we want to find for one kg. one kg is $0.30.

Multiply that by 7 and you get $2.10

Answer:

$23.10

Step-by-step explanation:

8.25 ÷ 2.5 = 3.3

7 x 3.3 = 23.10

you have to find out how much money you pay per kg

you pay $3.30 per kg

therefore you have to multiply the kg (7) by the price (3.30) and that's why you get $23.10

hope this helps :)

Answer:The answer is  pride 5

Step-by-step explanation:

Answer:

part A:

1/12 on day 1

1/4 or 3/12 on day 2

5/12 on day 3

Missy read 2/12 or 1/6 every day

Part B:

if day 1 is 1/12 and Friday is day 5 and she reads 2/12 per day

2/12 * 4 = 8/12

so 1/12 + 8/12 = 9/12 or 3/4 by Friday

Answer:

Monday: 1/12

Answer:

20

Step-by-step explanation:

It is mentioned that Jolyn made $340 in 17 hours last week. In order to evaluate this, you'll have to divide the money earned by the hours worked.

[tex]\frac{340}{17} =20[/tex]

Therefore, Jolyn makes $20 an hour as 20 x 17 = 340 which is correct,

Answer:

Step-by-step explanation:

→ Given angles of triangle = 45° + 45° + 90° {from <3>}

→ x = y {because of <1>}

→ H² = P² + B² (Pythagoras Theorem) {from <2>}

→ (12)² = x² + y²

→ 144 = x² + x² [x = y]

→ 144 = 2x²

→ 144/2 = x²

→ 72 = x²

→ √(72) = x

→ 6√2 = x

→ x = y

so,

x = 6√2 = y

The correlation Coefficient, R shows the degree or level of relationship between the dependent and independent variable. A positive R value denotes a positive correlation while a negative R value denotes a negative relationship. R values should range between - 1 to +1 with values close to 1 and - 1 depicting strength while value of zero means no relationship exist.

Hence, R value of -0.90 depicts a strong negative relationship. Hence, higher speed are related to lower miles per gallon and vice versa.
