Write the linear inequality shown in the graph. The gray area represents the shaded region. y ≤ –x + 4 y ≤ –x – 4 y ≥ –x – 4 y ≥ –x + 4
For Example:
Write the linear inequality shown in the graph. The gray area represents the shaded region.
A. y ≤ 3x + 4
B. y ≤ 3x – 4
C. y ≥ 3x + 4
D. y ≥ 3x – 4
Answer: C
Step-by-step explanation:
1. The graph indicates that the line intersect the y-axis at -4.
2. Then, you must choose any point that are located within the region and replace them to see if the inequality is satisfied. Therefore, you have:
Point (0,2)

Solve and explain. Sue orders pictures from her photographer. Each picture costs $8. A one-time shipping fee of $7 is added to the cost of every order. The total cost of Sue’s order is $31. How many pictures did Sue order?
Answer:
3 pictures
Step-by-step explanation:
Please see the attached pictures for the full solution.
☆ Since the shipping fee is a one-time fee, for an order, Sue only pays $7 once and the rest of the cost would be due to the number of pictures she ordered.

What is the surface area of the prism?
Answer:
Step-by-step explanation:
Since we know the total surface area of a prism is equal to the sum of all its faces, i.e., the floor, walls, and roof of a prism. Therefore, the surface area of a prism formula is given as: Total surface area of a prism = 2 x area of the base + perimeter of the base x Height.

Point S is between points R and T. Given that
RS ST and RS = 16, what is RT?
Answer:
32
Step-by-step explanation:
Reason: point S is between points are and t
Meaning that Line RS≅ST
So if RS=16 then ST=16
To find RT we just add ST and RS
16+16=32
Therefore RT=32

The Heat (H) required to melt copper is proportional to the copper’s mass in grams (g). Suppose the number of calories to melt 1 gram of copper is represented by c . Which statements are true for this situation
Answer:
H = cg The number of calories to melt one gram is the constant of proportionality. Heat = calories(mass) Write as y = kx, where k is the constant of proportionality → H = cg → c is the constant of proportionality

Trapezoid A B C D is shown. An altitude with length 5 is drawn from point B to side A D. The length of B C is 14, the length of C D is 6, and the length of base A D is 16. Use the formula A = One-halfh(b1 + b2). What is the area of the trapezoid? 32, 60, 75, 560, square units
Answer:
C. 75 square unitsStep-by-step explanation:
From the question we see that:
b1 = AD = 16 , b2 = BC = 14 , h = 5Use the formula for the area:
A = 1/2(b1 + b2)hA = 1/2(16 +14)(5) = 1/2(30)(5) = 75Correct choice is
C. 75 square unitsAnswer:
75 is correct on edge

Using the diagram below, identify the relationship of the pair of angles and find the value of x.
Answer:
The angles are supplementary to each other (their sum is 180 degrees)
x = 62°
Step-by-step explanation:
(2x+10) + 46 = 180
subtract 56 from each side
2x = 124
divide both sides by 2
x = 62°

Answer:
The normal distribution is explained for the solution of this question.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Mean = 25, Standard Deviation = 3.8
This means that [tex]\mu = 25, \sigma = 3.8[/tex]
So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{X - 25}{3.8}[/tex]
If P(X > k) = a
We have to find [tex]X = k[/tex] when Z has a pvalue of 1 - a.
If P(X < k) = a
We have to find [tex]X = k[/tex] when Z has a pvalue of a.
