Answer:
If Joseph was going to buy a large number of phones, and he bought the warranty on each phone, he should expect to lose value from the warranties.
Step-by-step explanation:
Given - Joseph just bought a brand new cell phone and a warranty for the cell phone. The warranty cost 300 euros and is worth 800 euros if his phone breaks. Joseph estimates that there is a 20% chance of his phone breaking.
Joseph calculates the expected value of buying the warranty to be -140.
To find - Which of the following statements are true?
Joseph will certainly lose value from the warranty.
Joseph will certainly gain value from the warranty.
If Joseph was going to buy a large number of phones, and he bought the warranty on each phone, he should expect to lose value from the warranties.
Proof -
Given that , expected value = -140
⇒It means Joseph lose 140
(negative represents loss )
Now,
Given the expected values, it means we have given the probability so we can not be sure about loosing money
So,
The 1st and 2nd option is wrong because certain means sure because in the question we are not sure that Joseph phone will break or not.
Now,
The 3rd option says that if Joseph buy large amount of phone then he expect to lose value from from warranties .
This is the correct option because if we buy phones and warranty on phone then the expected value will divide on each phone.
So, the chance of impact on loss will decrease.
The correct option is - If Joseph was going to buy a large number of phones, and he bought the warranty on each phone, he should expect to lose value from the warranties.

f(2)=−14 and g(2)=13 Find (f+g)(2).
Answer: The value of (f+g)(2) = -1
Step-by-step explanation:
Given: f(2)=-14 and g(2)=13
To find: (f+g)(2)
Addition of two functions:
(f+g)(x) = f(x)+g(x)
Then, (f+g)(2) = f(2)+g(2)
(f+g)(2) = -14+13 [given]
(f+g)(2) = -1
Therefore , the value of (f+g)(2) = -1

A regular hexagon is shown below. Find the value of x.
(11x + 21)°
Answer:
x=9
Step-by-step explanation:
The expression is for the interior angle of the hexagon; one interior angle is equal to .
Since an interior angle of a hexagon measures 120°, we have the equality
.
Now it is just a matter of solving for
11x=120-21
11x=99
x=99/11
x=9
The value of {x} for the hexagon shown is 9.
What is Hexagon?A hexagon is a polygon with 6 equal sides. The perimeter of a hexagon is the sum of all the six lengths. The measure of the interior angle of a hexagon is 120 degrees.
Given is to find the value of {x} in the Hexagon shown below.
The measure of the internal angle of a hexagon is 120 degrees. So, we can write -
(11x + 21) = 120
11x = 120 - 21
11x = 99
x = 9
Therefore, the value of {x} for the hexagon shown is 9.

7.511 155/20 8.3%
Answer:
155/20
Step-by-step explanation:
155/20 in decimal form is 7.75, which is only 0.25 off of 8
7.511 is 0.489 off of 8
8.3% is technically not anywhere near 8 because a percentage needs to be a percentage of something in order to make sense.
Which graph represents the solution to (x – 3)2 + (y + 4)2 > 36?
Answer:
second choice
Step-by-step explanation:
edge
The region outside the circle is under the consideration. Then the correct option is B.
What is an equation of a circle?A circle can be characterized by its center's location and its radius's length.
Let the center of the considered circle be at the (h,k) coordinate.
Let the radius of the circle be 'r' units.
Then, the equation of that circle would be:
(x – h)² + (y – k)² = r²
The inequality equation of the graph is given below.
(x – 3)² + (y + 4)² > 36
(x – 3)² + (y + 4)² > 6²
From the equation, the radius of the circle will be 6 units and the center of the circle will be (3, –4).
The region outside the circle is under the consideration.
Then the correct option is B.
The graph is given below.

Answer: [tex]y = \frac{1}{2}x+3[/tex]
This is the same as writing y = (1/2)x + 3
========================================================
Explanation:
Two points on the blue line are (0,3) and (2,4)
To go from the left point to the right, we go up 1 and over to the right 2.
Slope = rise/run = 1/2
Or we can use the slope formula to get the same value
m = (y2-y1)/(x2-x1)
m = (4-3)/(2-0)
m = 1/2
The y intercept is b = 3 because this is the location on the vertical y axis where the blue line crosses. This is the location (0,3).
With m = 1/2 and b = 3, we go from y = mx+b to y = (1/2)x + 3
On a piece of paper, that would look like the equation [tex]y = \frac{1}{2}x + 3[/tex]

-2a+7-3(-9-4a)
Answer: a=-3.4
Step-by-step explanation: you mean solve for a:)
-2a+7-3(-9-4a)=0 We would have to equal this equation to 0
-2a+7+27+12a=0 We multiply the -3 with the parentheses
10a+34=0 Add the like terms, and subtract 34 from both sides
10a=-34 Then divide both sides by 10
a=-3.4

From the attached image:
The parallel sides are 4m and 6m respectively while the height is 2,5m

The uncovered area
First, calculate the area of the rectangle
[tex]Area = Length * Width[/tex]
From the attachment
[tex]Length = 25m[/tex] and [tex]Width = 20m[/tex]

[tex]Area = 25m * 20m[/tex]
[tex]Area = 500m^2[/tex]
The area of the triangle is:
[tex]Area = \frac{1}{2} * Base * Height[/tex]
From the attachment
[tex]Base = 8m[/tex]
[tex]Height = 6m[/tex]
So:
[tex]Area = \frac{1}{2} * 8m * 6m[/tex]
[tex]Area = \frac{1}{2} * 48m^2[/tex]
[tex]Area = 24m^2[/tex]

For the function f(x) = -3sin(x) + 2, the distance between the maximum and minimum values is 6. Which statement must be true about this function? HINT: It's not B.
A. The amplitude is 3.
B. The midline is y = 3.
C. The period of the function is 3pi.
D. The range is [-3, 3].
Answer: A. The amplitude is 3.
Step-by-step explanation:
Given function : [tex]f(x) = -3sin(x) + 2[/tex]
Period of a sine function is [tex]2\pi.[/tex]
Since [tex]-1\leq \sin x \leq 1[/tex]
[tex]\Rightarrow\ -3\leq -3\sin x\leq 3\\\\\Rightarrow\ -3+2\leq -3\sin x+2\leq 3+2\\\\\Rightarrow\ -1\leq -3\sin x+2\leq 5[/tex]
i.e. Range is [-1,5]
Amplitude = 3 [coefficient of sin x]
Only option A. is correct.
