A. 90
B. 80°
C. 100°
D. 180°
Answer:
C. 100°
Step-by-step explanation:
Line n || Line p and line t is their transversal.
Therefore,
[tex]m \angle 8 = 100 \degree \\ (corresponding \: \angle s)[/tex]
The measure of the angle ∠8 will be 100°. Then the correct option is C.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Two parallel lines are cut by a transversal.
Alternate angle - If two lines are parallel then the third line will make z -angle and z-angles are equal angles with the parallel lines.
The angle 4 and angle 5 are alternate angles.
∠5 = ∠4
∠5 = 100°
Vertically opposite angle - When two lines intersect, then their opposite angles are equal.
The angle 8 and angle 5 are vertically opposite angles.
∠8 = ∠5
∠8 = 100°
Thus, the measure of the angle ∠8 will be 100°.
Then the correct option is C.

What is the Pythagorean triple generator and how does it work?
Answer:
Step-by-step explanation:
The Pythagorean Theorem states that
[tex]a^2+b^2=c^2[/tex]
or that the two legs added together squared equal the hypotenuse squared
not: this only works with right triangles
Now Pythagorean triples are the set of sides that follow that rule
an example would be 3,4,5
why is it a Pythagorean triple?
well because it follows
[tex]a^2+b^2=c^2[/tex]
[tex]3^2=9\\4^2=16\\16+9=25\\5^2=25[/tex]
25=25
a. Create a real world scenario of a study with a population mean and a population standard deviation. Include the information that a random sample of a given size (greater than 30) was selected from the population.
b. Check the conditions for the assumptions about the sampling distribution.
c. Draw, label and describe the sampling distribution in context.
Answer:
The t-score has the same interpretation as the z-score. It measures how far in standard deviation units \stackrel{-}{x} is from its mean μ. For each sample size n, there is a different Student’s t-distribution. The degrees of freedom, n – 1, come from the calculation of the sample standard deviation s. Remember when we first calculated a sample standard deviation we divided the sum of the squared deviations by n − 1, but we used n deviations \left(x-\stackrel{-}{x}\text{values}\right) to calculate s. Because the sum of the deviations is zero, we can find the last deviation once we know the other n – 1 deviations. The other n – 1 deviations can change or vary freely. We call the number n – 1 the degrees of freedom (df) in recognition that one is lost in the calculations. The effect of losing a degree of freedom is that the t-value increases and the confidence interval increases in width.
Properties of the Student’s t- Distribution 0.05, 95% level of confidence, we find the t-value of 1.96 at infinite degrees of freedom.

Answer:
£ 559.39
Step-by-step explanation:
To know the actual cost of replacing the flooring with new laminate, we must first obtain the total area of the floor. This can be obtained as follow:
1. Determination of the area of class room
Length (L) = 8.8 m
Breadth (B) = 220 cm
Area of class (A₁) =?
Next, we shall convert 220 cm to m. This can be obtained as follow:
100 cm = 1 m
Therefore,
220 cm = 220 cm × 1 m / 100 cm
220 cm = 2.2 m
Finally, we shall determine the area of the class as follow:
Length (L) = 8.8 m
Breadth (B) = 2.2 m
Area of class (A₁) =?
A₁ = L × B
A₁ = 8.8 × 2.2
A₁ = 19.36 m²
Therefore, the area of the class room is 19.36 m²
2. Determination of the area of storage cupboard
Length (L) = 2.3 m
Breadth (B) = 2.1 m
Area of cupboard (A₂) =?
A₂ = L × B
A₂ = 2.3 × 2.1
A₂ = 4.83 m²
Thus, the area of the cupboard is 4.83 m²
3. Determination of the total area of the floor.
Area of class (A₁) = 19.36 m²
Area of cupboard (A₂) = 4.83 m²
Total area (A) =?
A = A₁ + A₂
A = 19.36 + 4.83
A = 24.19 m²
The total area of the floor is 24.19 m²
4. Determination of the cost.
1.6 m² = £ 37
Therefore,
24.19 m² = 24.19 m² × £ 37 / 1.6 m²
24.19 m² = £ 559.39
Therefore, it will cost £ 559.39 to replace the flooring with new laminate.

On Saturday and Sunday jarrod went running and burned a total of 6475 calories he burned 320 of those calories on Saturday which addition equation could be used to find the number of calories c jarrod burned on Sunday
A 647.5+c=320
B. 320 + c = 647.5
C. 320 + 647.5=c
D. 647.5 + 320 =c
Answer:
The answer is B.
Step-by-step explanation:
It is saying that 647.5 calories is the total amount and 320 is a part of it. so when you do 647.5-320, it becomes 327.5 and that is c. You can only do this with the equation that letter B is saying.

What happens to a 44-degree angle if you rotate it 90 degrees counterclockwise? Explain your answer.
Answer:
it would melt
Step-by-step explanation:
at 40 degrees, the angle will stay in its natural shape. if increased to 90 degrees on the counter, and with the wisdom of mr. clock, the angle will start to warp, and lose its shape. evidently, if the angle is heated at a steady 90 degrees, the melting process will occur, and it will make a mess on your counter. thats why, when melting angles, I recommend putting it in a container, so as to not make too big of a mess.

The object above is made up of 1-inch cubes. What is the surface area of the object?
A.
52 inches2
B.
63 inches2
C.
48 inches2
D.
54 inches2
Answer:
52 inches2
Step-by-step explanation:
The figure is a rectangular solid with length (L) = 4 in., width (W) = 3 in. and height (H) = 2 in. To find the surface area, first find the area of each side and then add them together.
Sides 1 & 2 will have an area equal to L × W = 12 inches2.
Sides 3 & 4 will have an area equal to L × H = 8 inches2.
Sides 5 & 6 will have an area equal to W × H = 6 inches2.
The total surface area is
(2 × 12 in.2) + (2 × 8 in.2) + (2 × 6 in.2)
= 24 in.2 + 16 in.2 + 12 in.2
= 52 inches2.

A large software development firm recently relocated its facilities. Top management is interested in fostering good relations with their new local community and has encouraged their professional employees to engage in local service activities. They believe that the firm's professionals volunteer an average of more than 21 hours per month. If this is not the case, they will institute an incentive program to increase community involvement. A random sample of 24 professionals yields a mean of 22 hours and a standard deviation of 2.22 hours.
12 13 14 14 15 15 15 16 16 16 16 16
17 17 17 18 18 18 18 19 19 19 20 21
The sample has a mean of 16.6 hours and a standard deviation of 2.22 credit hours.
At α = 0.05,
I. we reject the null hypothesis.
II. we fail to reject the null hypothesis.
III. the firm shouldn't need to institute an incentive program because the evidence indicates that professional employees volunteer an average of more than 15 hours per month in their local community.
a. II and III
b. I and III
c. II only
d. I only
e. III only
Answer:
B. i and iii
Step-by-step explanation:
There are mistakes in your question. But I solve this problem using the average mean of 15 because that is what is contained in the solution
Hypothesis
H0: u <= 15
H1: u > 15
Mean of x = 16.6
S = 2.22
Test statistic used is t test
16.6 - 15 / 2.22/√24
= 3.531
We find the critical value
Degree of freedom = 24-1 = 23
This is a one tailed test
Critical value = 1.714
We find p value using Ms excel T distribution function
= 0.000894
To make the decision
3.531 > 1.714 so we conclude that
I.) Reject null hypothesis
Iii) conclude an average if more than 15 hours is volunteered per month. So no need to institute the program.
The answer option Is B
