The following statements are true.
A rhombus is a parallelogram with equal sides. In a parallelogram, opposite sides are equal. The area of a rhombus is found using the formula A = b × h. b and h represents the base and height of the rhombus respectively. The area is found the same way for both a rhombus and a parallelogram. The formula, area = base × height can be used for both rhombus and parallelogram.Step-by-step explanation:

The line of best fit for the graph above has the equation
y = -3x + 2. What value does the line predict when x = 9?
Answers
Answer:
y = -25
Step-by-step explanation:
The equation of line is given as :
y = -3x + 2
We need to find the value when x = 9.
Put x = 9 in the given equation. So,
y = -3(9)+ 2
= -27+2
= -25
So, the value of line is equal to -25.
A truck has 475 apples on it. It makes a delivery of 215 apples to the farmer's market. The rest of the apples on the truck are delivered to the grocery store. How many more apples were delivered to the grocery store than to the farmer's market?

Based on the survey results, there is a probability that a randomly selected person will feel guilty about wasting food and a probability that a randomly selected person will feel guilty about leaving lights on when not in a room. Moreover, there is a probability that a randomly selected person will feel guilty for both of these reasons.
Required:
a. What is the probability that a randomly selected person will feel guilty for either wasting food or leaving lights on when not in a room or both (to 2 decimals)?
b. What is the probability that a randomly selected person will not feel guilty for either of these reasons (to 2 decimals)?
Answers
This question is incomplete, the complete question is;
he Eco Pulse survey from the marketing communications firm Shelton Group asked individuals to indicate things they do that make them feel guilty (Los Angeles Times, August 15, 2012).
Based on the survey results, there is a 0.39 probability that a randomly selected person will feel guilty about wasting food and a 0.27 probability that a randomly selected person will feel guilty about leaving lights on when not in a room.
Moreover, there is a 0.12 probability that a randomly selected person will feel guilty for both of these reasons.
Required:
a. What is the probability that a randomly selected person will feel guilty for either wasting food or leaving lights on when not in a room or both (to 2 decimals)?
b. What is the probability that a randomly selected person will not feel guilty for either of these reasons (to 2 decimals)?
Answer:
a)
the probability that a randomly selected person will feel guilty for either wasting food or leaving lights on when not in a room or both is 0.54
b)
the probability that a randomly selected person will not feel guilty for either of these reasons is 0.46
Step-by-step explanation:
Given the data in the question;
lets A represent person feels guilty about wasting food and B represent leaving the light on when not in room;
probability; feel guilty about wasting food P(A) = 0.39
probability; feel guilty about leaving light on P(B) = 0.27
probability; feel guilty for both P(A ∩ B ) = 0.12
a)
probability that a randomly selected person will feel guilty for either wasting food or leaving lights on when not in a room or both
p( A ∪ B ) = P(A) + P(B) - P(A ∩ B )
we substitute
p( A ∪ B ) = 0.39 + 0.27 - 0.12
p( A ∪ B ) = 0.54
Therefore, the probability that a randomly selected person will feel guilty for either wasting food or leaving lights on when not in a room or both is 0.54
b)
probability that a randomly selected person will not feel guilty for either of these reasons;
p( A ∪ B )' = 1 - p( A ∪ B )
p( A ∪ B )' = 1 - 0.54
p( A ∪ B )' = 0.46
Therefore, the probability that a randomly selected person will not feel guilty for either of these reasons is 0.46

What is the solution of the equation z +8 = 21?
Answers
Answer: 13
Explanation:
21-8=13
z = 13 is the solution of the equation z +8 = 21.
What is simplification?When a mathematical expression is converted into an equivalent, typically shorter statement, it becomes simpler. Procedure simplification is one method to encourage uniformity in work effort, expense, and duration. It reduces diversity and variation that is detrimental, pointless, or unnecessary.
Given, an expression z + 8 = 21
Simplifying it,
z = 21 - 8
z = 13
Therefore, The answer to the equation z + 8 = 21 is z = 13.

2. What is the test statistic? Give your answer to four decimal places.
3. What is the critical value for the test? Give your answer to four decimal places.
4. What is the appropriate conclusion?
Answers
Answer:
H0 : μ = 10
H1 : μ < 10
Test statistic = - 2.0415
Critical value = -1.4051
There is significant evidence to conclude that the mean time a user stays on site is less than 10 minutes
Step-by-step explanation:
The null and alternative hypothesis :
H0 : μ = 10
H1 : μ < 10
The test statistic :
From the data Given, using calculator :
Sample mean, xbar = 6.3
Sample standard deviation, s = 7.90
Test statistic = (xbar - μ) ÷ (s/sqrt(n))
Number of samples given is 19 and not 17 as stated in the question.
Test statistic = (6.3 - 10) ÷ (7.90 / sqrt(19))
Test statistic = - 3.7 / 1.8123842
Test statistic = - 2.0415
The critical value for the test :
At α = 0.08 ;
Critical value = -1.4051
Since, Test statistic is < Critical value ;
-2.0415 < - 1.0451 ; we reject the Null
There is significant evidence to conclude that the mean time a user stays on site is less than 10 minutes

Heather paid $37.50 for a pizza to be delivered to her house. She had a coupon for 30% off and
there is a tax of 8%. What was the total cost of the pizza to be delivered?
Answers
Answer:
The original cost of the pizza before the discount coupon and the tax was $49.28.
Step-by-step explanation:
Given that Heather paid $ 37.50 for a pizza to be delivered to her house, and she had a coupon for 30% off and there is a tax of 8%, to determine what was the total cost of the pizza to be delivered, the following calculation has to be done:
100 - 8 = 92
100 = 37.50
92 = X
92 x 37.50 / 100 = X
34.50 = X
100 - 30 = 70
70 = 34.50
100 = X
100 x 34.50 / 70 = X
49.28 = X
Thus, the original cost of the pizza before the discount coupon and the tax was $ 49.28.
