Answer:
(B) -8
Step-by-step explanation:
Given the 2-column table below:
[tex]\left|\begin{array}{c|c}x&y\\--&--\\-3&14\\-1&10\\1&6\\4&0\\8&?\\10&-12\end{array}\right|[/tex]
Taking the pair (-3,14) and (-1,10)
[tex]Slope, m=\dfrac{10-14}{-1-(-3)} =\dfrac{-4}{2} =-2[/tex]
Taking the pair (1,6) and (4,0)
Slope, [tex]m=\dfrac{0-6}{4-1} =\dfrac{-6}{3} =-2[/tex]
Since the slope is constant, the table represents a linear function whose slope is -2. Therefore:
Taking the pair (8,y) and (4,0)
Slope, [tex]m=\dfrac{0-y}{4-8} =-2[/tex]
[tex]\dfrac{-y}{-4} =-2\\y=-2*4=-8[/tex]
Therefore, the value of ? on the y-column is -8.

The solution is, the 30th term of the sequence a_30 = 96.
What is Arithmetic progression?An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.
For instance, the sequence 5, 7, 9, 11, 13, 15.. . is an arithmetic progression with a common difference of 2.
The nth term of AP : a_n = a + (n – 1) × d
here, we have,
the given sequence is,
-20,-16, -12,-8,-4, ...
so, here, we have,
a = -20
d = 4
so, the 30th term of the sequence is,
a_30 = a + (30-1) d
= -20 + 29*4
= 96
Hence, The solution is, the 30th term of the sequence a_30 = 96.

Answer: 42/11 = 21/5.5
Step-by-step explanation:
1) Since the hypotenuse is 42 for one of the triangles it must be similar to the other triangles hypotenuse, 11.
2) Therefore, the ratio is 42/11.
3)The adjacent sides to the right angle are 21 and 5.5.
4)Therefore, the ratio is 21/5.5

There are 1800 students in a school. 53.5% of them are male. How many are female?
Answer:
Step-by-step explanation:
837 are females as 52.5 percent of 1800 equals 837.
Answer:
Females = 100 - percent of males = 100 - 53.5 = 46.5%
Number of females = 46.5/100 × 1800 = 837

LeAnn wants to giftwrap a present she got for her little brother. How many square inches of giftwrap will be needed to cover a box that is 4in x 6in x 2in? In your final answer, include all of your calculations.
Answer: 88 square inches
If we want to wrap the box, we need to work out its surface area - the area that will need to be covered by the giftwrap.
This box is a cuboid, so there will be six faces, with only three different areas (each face has an identical pair).
Let's say the height is 2 in, the length is 6 in and the depth 4 in.
height = 2
length = 6
depth = 4
Let's find the area of the faces that measure height x length:
2 x 6 = 12 square in
Now let's do the same thing for height x depth:
2 x 4 = 8 square in
And finally for length x depth:
6 x 4 = 24
There are two of each of these faces, so let's multiply each result by two.
12 x 2 = 24
8 x 2 = 16
24 x 2 = 48
Finally, all that's left to do is add these numbers together to find the total surface area of the cuboid.
24 + 16 + 48 =
88 square inches

There are 7 red 3 green 2 blue and 8 purple marbles in a bag if a marble is randomly chosen 250 times predict how many times it should be red or green
Answer:
It should be red or green 125 times
Step-by-step explanation:
The first thing to do here is to calculate the probability of selecting a red or a green marble
Total number of marbles = 7 + 3 + 2 + 8 = 20
Probability of selecting a red marble is 7/20
Probability of selecting a green marble is 3/20
The probability of selecting a red or a green marble = Probability of selecting a red marble + Probability of selecting a green marble = 7/20 + 3/20 = 10/20 = 1/2
Now our selection spans 250 times, the number of times it should have been a green or a red marble = The probability of selecting a green or a red marble * number of selection times = 1/2 * 250 = 125 times

Ron is cooking a meal for some friends. A package of corn contains 8 cups and a serving size is 1 cup. Ron wants to allow 2 servings for each of 11 people.
Answer:
See Explanation
Step-by-step explanation:
The text of the question is incomplete. However, the likely question that can be asked may imply that; "what number of corn package did she use?"
Given that
1 package of corn = 8 cups
1 serving = 1 cup
Total individual = 11
Servings per individual = 2
If there are 2 servings per individual then 1 package of corn will serve the following number of people.
1 package of corn = 8 / 2 individuals
1 package of corn = 4 individuals
Divide both sides by 4.
1 package of corn / 4 = 4 individuals / 4
¼ package of corn = 1 individual.
Re-arrange
1 individual = ¼ package of corn.
So, this means that 11 individuals will get;
[Multiply both sides by 11]
11 * 1 individual = ¼ * 11 package of corn
11 individuals = 11/4 package of corn
11 individuals = 2.75 packages of corn.
Hence, Ron will need 2.75 packages of corn for 11 individuals
A restaurant advertises that its burritos weigh 250 g 250 g250, start text, space, g, end text. A consumer advocacy group doubts this claim, and they obtain a random sample of these burritos to test if the mean weight is significantly lower than 250 g 250 g250, start text, space, g, end text.
Answer: C) H0 : μ = 250 , Ha: μ < 250
Step-by-step explanation:
The questions is incomplete. The correct question is
A restaurant advertises that its burritos weigh 250 g. A consumer advocacy group doubts this claim, and they obtain a random sample of these burritos to test if the mean weight is significantly lower than 250 g. Let u be the mean weight of the burritos at this restaurant and ĉ be the mean weight of the burritos in the sample. Which of the following is an appropriate set of hypotheses for their significance test? Choose 1 answer:
A) H0 : x = 250 , Ha : x < 250
B) H0 : x = 250 , Ha : x > 250
C) H0 : μ = 250 , Ha: μ < 250
C) H0 : μ = 250 , Ha: μ > 250
Solution:
The null hypothesis is the hypothesis that is assumed to be true. The restaurant advertises that its burritos weigh 250. This is the null hypothesis. 250 is the population mean,μ . Thus, the null hypothesis is
H0 : μ = 250
The alternative hypothesis is what the researcher expects or predicts. The consumer advocacy group tests if the mean weight is significantly lower than 250g. This is the alternative hypothesis. It is expressed as
H0 : μ < 250

A gift box is in the shape of a trapezoidal prism with base lengths of7 inches and 5 inches and a height of 4 inches. The height of the gift box is 8 inches. What is the volume of the gift box?
Answer:
192 in³
Step-by-step explanation:
A trapezoidal prism is a three dimensional solid that has two similar trapezoids at its top and base.The two similar trapezoids are connected by four rectangles connecting the corresponding sides of the two bases.
The Area of the trapezoid at the top or base = 1/2 (a + b)h
Where a and b are the lengths = 7 inches and 5 inches and the height (h) = 4 inches.
Therefore Area of the trapezoid at the top or base = 1/2 (a + b)h = 1/2(7 + 5)4 = 24 in²
The volume of gift box = Area of the trapezoid at the top or base × height of gift box = 24 × 8 = 192 in³
Bartolo is running a race. He determines that if he runs at an average speed of 15 feet/second, he can finish the race in 6 seconds. If he runs at an average speed of 18 feet/second, he can finish the race in 5 seconds. Which equation represents this inverse variation?
Answer:
The Equation that represents these inverse variation is:
Speed is inversely proportional to Time
Speed (S) ∝ 1/ Time(T)
And the constant of proportionality = Distance(D)
Therefore, Speed = Distance/ Time
Step-by-step explanation:
For an inverse variation, one element increases while the other element decreases. In this question, the element or variable that increases is the speed while the element or variable that decreases is the time.
We can see from the question that
a) If he runs at an average speed of 15 feet/second, he can finish the race in 6 seconds.
b) If he runs at an average speed of 18 feet/second, he can finish the race in 5 seconds
Speed is inversely proportional to Time because the higher the speed, the lesser the time it takes to go or move in a particular direction or to go in a particular distance.
Hence, the Equation that represents these inverse variation is:
Speed is inversely proportional to Time
Speed (S) ∝ 1/ Time(T)
For inverse variation or proportionality, a constant is always needed
And the constant of variation or proportionality = Distance(D)
Therefore, Speed = Distance/ Time
