Let the random variable X represent the number of orders placed until the first daily special is ordered. The distribution of X is geometric and has an expected value of approximately 2.86. Which of the following is the best interpretation of the expected value?
A. Each day, 3 customers will order the daily special.
B. Over many days, the average number of customers ordering the daily special is approximately 2.86.
C. Over many days, it takes about 2.86 orders, on average, to be placed until the first daily special is ordered.
D. For a random sample of the days, the average number of orders of the daily special will be 2.86.
E. Each day, the ratio of the number of orders of the daily special to the number of orders of other menu items is about 2.86 to 1.
Answer:
C. Over many days, it takes about 2.86 orders, on average, to be placed until the first daily special is ordered.

Option C. Over many days, It takes about 2.86 orders, on average, to be placed until the first daily special is ordered.
What Is a Random Variable?A random variable is a variable whose value is unknown or a function that assigns values to each of an experiment's outcomes. Random variables are often designated by letters and can be classified as discrete, which are variables that have specific values, or continuous, which are variables that can have any values within a continuous range.
Given here: The distribution of X is geometric and has an expected value of approximately 2.86. And 35 percent of the customers order the daily special each day. Thus clearly the correct and precise interpretation of the statement is Over many days, It takes about 2.86 orders, on average, to be placed until the first daily special is ordered.
Hence, Option C is the correct answer.

Select all of the descriptions which describe a transformation of the graph of f(x)=x that could result in
the graph of g(x) = 2x.
A. The graph is translated 2 units to the right.
B. The graph is rotated about (0,0), becoming steeper.
C. The graph is vertically stretched.
D. The graph is translated 2 units up.
E. The graph is vertically shrunk.
F. The graph is reflected across the x-axis.
Answer:
The descriptions that apply are E and F.
Step-by-step explanation:
Let's graph both functions, attached the result:
A: No. The graph is not reflected across x-axis. For this to happen, there should be a negative sign: g(x) = -x, for example
B: No, the graph doesn't translate. The graph only translates if there is: g(x) = a(x-c)+b, where b defines the vertical translation, and c the horizontal one.
C: No. This would happen for g(x)=x/2, for example.
D: No. Check the explanation of B.
E: Yes. The graph rotates due to the factor of 10. This rotation only applies for straight lines.
F: Yes. It stretched.

To find the area of a rectangle, multiply the length and the width.
The length of a rectangle is (X - 6) and the width of the rectangle is (x - 10). What is the area of the rectangle?
Answer:
Step-by-step explanation:
area = length * width
area = (x - 6) (x - 10)
area = x (x - 10) - 6 (x - 10)
area = x^2 -10x -6x -10
area = x^2 -16x -10

Enter a range of values for x:
A

D
35°
20°
B
4X4
С
1
Answer:
The correct answer to the question is;
1 < x < 4
Step-by-step explanation:
The give parameters are;
ΔABC is an isosceles triangle, with the vertex angle = 35° + 20° = 55°
Therefore, the two base angles are 62.5° each by definition of isosceles triangle
Given that the angle subtended by 4·x - 4 which is 25° is lesser than the angle subtended by the 12 unit side length which is 35° we have;
4·x - 4 < 12
4·x < 12 + 4
∴ 4·x < 16
x < 16/4
x < 4
Therefore, the range is 1 < x < 4
Write an equation in slope-intercept form for the line with slope 7 and y-intercept -8.
Answer:
y = 7x - 8
Step-by-step explanation:
The equation of a line in slope-intercept form is: y = mx + b, where m is the slope and b is the y-intercept.
The problem already gives us both of these values:
m = 7
b = -8
All we have to do is plug them in:
y = mx + b
y = 7x + -8
y = 7x - 8
Thus, the answer is y = 7x - 8.
The local newspaper has letters to the editor from 10 people. If this number represents 4% of all of the newspaper's readers, how many readers does the newspaper have?
Answer:
The local newspaper has 250 readers in total
Step-by-step explanation:
Given that
Letter to the editor = 10
Also it is given that 10 is the 4% of total readers of the newspaper.
Let x be the number of readers of the newspaper
It can be written as:
[tex]10 = 4\%\ of\ x[/tex]
Converting the percentage into decimal
[tex]10 = 0.04x\\\frac{10}{0.04} = \frac{0.04x}{0.04}\\x = 250[/tex]
The newspaper has 250 readers.
Hence,
The local newspaper has 250 readers in total
Mary is going to have an outdoor party in 10 days. She wants to have her backyard pond covered in water lilies before the party, so she goes to the nursery to buy some water lilies. Mary gives the clerk the dimensions of her pond, and the clerk, knowing the growth rate of the water lilies that he stocks, calculates that if she purchases a single water lily, it will produce a population of ten thousand lilies that will completely cover the surface of the pond in 20 days. Mary reasons that if she buys two water lilies instead of one, she can meet her goal of having the pond surface covered in 10 days. Is there anything wrong with Mary's reasoning? How many water lilies will Mary need to buy to meet her goal?
Answer:
a. There is nothing wrong with Mary's reasoning b. 2 water lilies.
Step-by-step explanation:
a. This is because, she reasons that if she doubles the amount of water lilies she buys, it would take half the time it takes to produce 10,000 lilies. So, there is nothing wrong with Mary's reasoning.
b. Since it takes 1 water lily to produce 10000 lilies in 20 days, 1 water lily will produce x lilies in 10 days.
So, x = 10000 × 10/20 = 5000 lilies
So, 1 water lily produces 5000 lilies in 10 days.
So, x water lilies will produces 10000 lilies in 10 days.
So x = 10000 × 1/5000 = 2 water lilies
So, 2 water lilies will produce 10000 lilies in 10 days.
So, Mary needs 2 water lilies so she can meet her goal of having the pond surface covered in 10 days.

Which of the following additional statements would you need to prove these two triangles are similar by SAS similarity?
1. ∠A ≅ ∠D
2. ∠B ≅ ∠E
3. ∠B ≅ ∠F
4. ∠C ≅ ∠F
Answer:
option 1
as the sides were already given, A and D are the only way that the triangle can have SAS.
The option 1 . ∠A ≅ ∠D is correct and needed to apply SAS similarity theorem in this given condition.
What is SAS (side angle side ) similarity theorem for two triangles?The SAS theorem states that if two triangles have a congruent angles and the sides that define the angle are proportional, the two triangles are similar.
Given are two triangles ΔABC and ΔDEF and their sides AB =7 , AC = 12, DE =14, DF = 24
Then AB/ DE = 7/14 = 1/2
and AC / DF = 12/24 = 1/2
∴ AB / DE = AC/ DF
Therefore the sides AB and AC are proportional to DE and DF
And for the application of SAS the angle defined by these pairs must be congruent.
AB and AC defines ∠A and DE and DF defines ∠D
Thus, ∠A must be congruent to ∠D so that SAS can be to applied to make the given triangles similar.
Therefore, option 1. ∠A ≅ ∠D is correct option

Answer:
∠KYR = 43 degrees
Step-by-step explanation:
1. We know that the entire angle equals to 90 degrees because it is a right angle.
First you have to find the value of c and to do this, you add the values of both angles and make it equal to 90
3c + 64 + 5c + 82 = 90]
8c + 146 = 90
- 146 -146
8c = -56
c = -7
Now we have to find the value of angle KYR so just plug in -7 for c
3(-7) + 64 = 43
