Answer:
D) P - 3
Step-by-step explanation:
"fewer than" a number means "less than" a number. So "3 fewer than" means "subtract 3" from the number.
⇒ P - 3
The table shows the number of gallons of gas used and the number of miles driven. Gallons of Gas Used 12 15 18 12 14 16 Miles Driven 300 400 450 350 400 450 Is the resulting data set a function? Explain your reasoning. A The table is a function. The function can have more than one input value paired with the same output value. B The table is a function. The function can have more than one output value paired with the same input value. C The table is not a function. The function cannot have different input values paired with the same output value. D The table is not a function. The function cannot have the same input value paired with different output values.
There is one input being mapped into two different outputs, so this is not a function. The correct option is D.
What is a function?A function is a relation that maps elements from one set (the domain) into elements from another set (the range). Such that each element from the domain can be mapped into only one element from the range.
In this case, the table is:
Gallons of Gas Used: 12 15 18 12 14 16Miles Driven: 300 400 450 350 400 450So, the input "12" appears twice, the first time is mapped into 300 miles, and the second time is mapped into 350.
So the same value from the domain is being mapped into two different values of the range, meaning that this is not a function. So the correct option is D.

Two cars leave New York at the same time traveling in opposite directions. One travels at an average speed of 59mph and the other at 58mph. In how many hours will they be 468 miles apart?
Answer: In 4 HOURS they will be 468 miles apart.
Step-by-step explanation:
1st car DATA:
rate = 59 mph ; time = x hrs. ; distance = 59x miles
2nd car DATA:
rate = 58 mph ; time = x hrs. ; distance = 58x miles
EQUATION:
distance + distance = 385
59x + 58x = 468
117x = 468
x = 4 hours.

Answer:
828 in²
Step-by-step explanation:
To find the surface area of a triangular prism, you find the area of each side and add them together.
Find the area of each rectangular side:
Side 1 : 9 × 20 = 180 in²
Side 2 : 15 × 20 = 300 in²
Side 3 : 12 × 20 = 240 in²
Find the area of the triangular sides:
Area of a Triangle = [tex]\frac{1}{2}[/tex]bh
As you can see, 9 and 12 both work as the height/base for the triangular sides, so
Δ Side 1 = [tex]\frac{1}{2}[/tex]bh = [tex]\frac{1}{2}[/tex](9)(12) = 54
Δ Side 2 is also 54.
Add the areas of all the sides together:
180 + 300 + 240 + 54 + 54 = 828 in²

The continuous random variable N has a normal distribution with mean 7.5 and standard deviation 2.5. For which of the following is the probability equal to 0 ?
P(N=8)
P(N>8)
P(N<8)
P(7 8)
Using the normal distribution, it is found that P(X = 8) is equals to zero.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It 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, which is the percentile of X.As in any continuous distribution, the probability of an exact value, that is, P(X = x), is of 0.Hence, from the last bullet point, it is found that P(X = 8) is equals to zero.

If the radius of a circle is decreased by 20%, find the percentage decrease in its area.
Answer:
36%
Step-by-step explanation:
Area of circle is
[tex]\pi {r}^{2} [/tex]
If the radius is decreased by 20%. Then the radius will be
80% of the original radius.
So our radius is 0.8.
So our area is
[tex]\pi(0.8r) {}^{2} [/tex]
[tex]\pi(0.64 {r}^{2} )[/tex]
Since pi is constant, the radius only really matters.
We went from
[tex]1 {r}^{2} [/tex]
to
[tex]0.64 {r}^{2} [/tex]
So our area will decrease by 36%
Proof: Let the radius be 10.
So the area of circle will be
[tex]\pi(10) {}^{2} = 100\pi[/tex]
Let our other radius is 8 because 8 is a 20% decrease of the orginal radius
[tex]\pi(8) {}^{2} = 64\pi[/tex]
Next, we subtract the area to find decrease in area
[tex]100\pi - 64\pi = 36\pi[/tex]
Since pi is constant, we can ignore it so our decrease in area is 36%

Increase 400 by 10% and then decrease the answer by 10%
Answer:80
Assume the number to be 400 for instance,
10% of 400 increased = 400 + ( 10/100 × 400 )
= 400 + 40 = 440
The resulting number decreased by its 10% = 400 - (10/100 × 400)
= 400 - 40 = 360
Now, net decrease = 440 - 360 = 80
Answer:
400.
10% of 400 is 40 (Simply reduce the hundreds place to the tens place)
So now we have 440.
Decrease it by 10% again, and that brings you right back to 400.
The length of a rectangle is 6 inches more than the width. If the perimeter is 68 inches, what are the length and the width?
Answer: The length of the rectangle would be 20 inches and the width would be 14 inches.
Step-by-step explanation:
If the length is 20, first, it’s 6 more than 14, and second it would add up to 40. If the width is 14, it’s 6 less than 20, and adds up to 28. If you add those two together, you’d get your total of 68 inches for the perimeter!

Problem 3
Answer: Not possible to solveA triangle cannot be constructed with these parameters.
----------------------------
Explanation:
Use the Law of Sines to find angle B
sin(A)/a = sin(B)/b
sin(120)/12 = sin(B)/13
sin(B) = 13*sin(120)/12
sin(B) = 0.93819419
B = arcsin(0.93819419) or B = 180 - arcsin(0.93819419)
B = 69.75047247 or B = 180 - 69.75047247
B = 69.75047247 or B = 110.24952753
These angle values are approximate.
-----------
If B = 69.75047247, then,
A+B+C = 180
C = 180 - (A+B)
C = 180 - (120 + 69.75047247)
C = -9.75047247000001
We get a negative result which isn't valid.
This means B = 69.75047247 isn't valid either.
-----------
If B = 110.24952753, then,
A+B+C = 180
C = 180 - (A+B)
C = 180 - (120 + 110.24952753)
C = -50.24952753
We get a similar conclusion here as well.
-----------
No matter what value of B we go with, we end up with a negative value for angle C.
Negative angles are not allowed.
Therefore, we cannot construct a triangle with sides a = 12, b = 13 and angleA = 120 degrees.
This is one example of an SSA triangle leading to no possible solutions. Refer to the SSA ambiguous case for more info.
-----------
Check out the diagram below. Imagine that point B can be anywhere on the dotted circle. Imagine it can rotate around as in an animation. This circle is centered at point C and has radius a = 12. No matter where point B is placed, we cannot get it to land on the horizontal line to therefore form a triangle. Simply put: side a = 12 is too short.
I used GeoGebra to make the diagram and make sure it's to scale. This is to visually verify that we cannot construct such a triangle with these parameters.

A rhombus is a quadrilateral where all four sides are equal and the opposite angles are equal.
3x - 4 = 3y + 8 = -2x - 9 = 39
The value of x is 43/3
The value of y is 31/3
The value of z is -24
What is a rhombus?A rhombus is a quadrilateral where all four sides are equal and the opposite angles are equal.
We have,
Rhombus:
All four sides are equal.
So,
3x - 4 = 3y + 8 = -2x - 9 = 39
Now,
3x - 4 = 39
3x = 39 + 4 = 43
3x = 43
x = 43/3
3y + 8 = 39
3y = 39 - 8
3y = 31
y = 31/3
-2z - 9 = 39
-2z = 39 + 9
-2z = 48
z = -24
Thus,
The value of x is 43/3
The value of y is 31/3
The value of z is -24
