how do I find "Z"? of possible can you do a step by step?
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
Determine the type of bias involved. In a study of the effectiveness of wearing seat belts, a group of people who had survived car accidents in which they had not worn seat belts reported that seat belts would not have helped them. The type of bias involved in the given information i
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.
Heres the picture, thank you!
Answer:
x = 6√(2)x = 6√(2)y = 6√(2)Step-by-step explanation:
Sides equal opposite to equal angles are always equal -----------<1>If one angle of triangle is 90°, then it is a right triangle, can find sides with the help of Pythagoras Theorem. -----------<2>The sum of all three sides of any triangle is 180°. -----------<3>→ 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
x = 6√(2)y = 6√(2)HOPE THIS HELPS YOU

Missy read 1/12 of a book by Monday 1/4 of the book by Tuesday and 5/12 of the book by Wed. if the pattern continues how much of the book will she have read by Fri. draw a chart or explain
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
Tuesday: 3/12
Wednesday: 5/12

Jolyn was paid $340 last week working 17 hours. What was Jolyn’s hourly pay? Do not include the units in your answer
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,
If 2.5 kg of tomatoes cost $8.25, how much will you pay for 7 kg?
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 :)

A department of transportation's study on driving speed and miles per gallon for midsize automobiles resulted in the following data. Speed (Miles per Hour) 30 50 40 55 30 25 60 25 50 55 Miles per Gallon 29 26 26 22 29 31 21 35 25 26 Compute the sample correlation coefficient. (Round your answer to two decimal places.) Interpret the sample correlation coefficient. There is a strong negative relationship between the driving speed and miles per gallon. For driving speed between 25 and 60 miles per hour, higher speeds are associated with lower miles per gallon.
Answer:
R = -0.90 (2 decimal places)
Step-by-step explanation:
Given the data :
Speed (Miles per Hour) :
30
50
40
55
30
25
60
25
50
55
Miles per Gallon :
29
26

22
29
31
21
35
25
26
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.
