Answer:
56
Step-by-step explanation:
So you just need to find 7 + what is equal to 63. To find this we have to do inverse operation, which means the opposite operation. So, we do 63-7 which is equal to 56. Therefore, the solution to the equation, or x is equal to 56 (C).

In a recent sample of 84 used car sales costs, the sample mean was $6,425 with a standard deviation of $3,156. Assume the underlying distribution is approximately normal.a. Which distribution should you use for this problem
Answer:
By the Central Limit Theorem, an approximately normal distribution, with mean $6425 and standard deviation $344.35.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Sample mean was $6,425 with a standard deviation of $3,156
This means that [tex]\mu = 6425, \sigma = 3156[/tex]
Sample of 84:
This means that [tex]n = 84, s = \frac{3156}{\sqrt{84}} = 344.35[/tex]
a. Which distribution should you use for this problem?
By the Central Limit Theorem, an approximately normal distribution, with mean $6425 and standard deviation $344.35.

What is the value of x?
x = [ ? 10
9514 1404 393
Answer:
30
Step-by-step explanation:
The triangle inside the circle is an equilateral triangle, so the central angle is 60°. That angle is one of the acute angles in the right triangle formed by the tangent line. The other acute angle (x°) in that right triangle is the complement of 60°.
x° = 90° -60° = 30°
x = 30
What is the value of f[g(3)] for the functions f(x) =x+2 and g(x) = 5x - 1

Step-by-step explanation:
In this case we know the composition of f and g is
[tex]f(g(x))=f(5x-1)=5x-1+2=5x+1[/tex]
Thus if we change x by 3 we get

Figures A and b are similar. Figure A has an area of 18 square feet. Figure b has an area of 98 square feet and one of the sides lengths is 14 feet find the corresponding side length
Answer:
6 ft
Step-by-step explanation:
The ratio of the square of the sides of two similar figures = the ratio of their area
Let x represent the missing side corresponding side length
Therefore,
Area of figure B/area of figure A = square of side length of figure B/square of the side length of figure A
Thus:
98/18 = 14²/x²
98/18 = 196/x²
Cross multiply
98*x² = 196*18
98x² = 3,528
Divide both sides by 98
x² = 3,528/98
x² = 36
x = √36
x = 6
Therefore, missing corresponding side length = 6 ft
The corresponding side length is 2.57 feet
Similar shapesGiven that figures A and b are, hence the ratio of the area to the length is equal to a constant as shown:
[tex]\frac{A}{L} = \frac{a}{l}[/tex]Substitute the given parameters into the formula to have:
A = 98 square feet
L = 14 square feet
a 18 square feet
[tex]\frac{98}{14} = \frac{18}{l}\\98l=252\\l = 2.57 feet[/tex]
Hence the corresponding side length is 2.57 feet

Answer:
x = 1
Step-by-step explanation:
2x + 3 = 5
=> 2x = 5-3
=> 2x = 2
=> x = 2/2
=> x = 1
Therefore, the value of x is 1
Hope it helps :)
Answer:
x=1
Step-by-step explanation:
Hi there!
2x+3=5
Our goal is to isolate x on one side of the equal sign, and we can do this using inverse operations. For example, the inverse operation of addition is subtraction. Subtract both sides of the equation by 3 to isolate 2x:
2x+3-3=5-3
2x=2
The inverse of multiplication is division. Divide both sides by 2:
2x÷2=2÷2
x=1

A sailor cut a 40 foot length of rope in two pieces. If the longer piece is five feet less than twice the shorter piece of rope, then how long is the longer piece.
Answer:
23ft longer
Step-by-step explanation:
The shorter piece is 15 feet, while the longer piece is 25 feet
Let the longer piece be y, and the shorter piece be x.
So, we have:
[tex]x + y = 40[/tex] --- the length of the rope
[tex]y =2x - 5[/tex] --- the relationship between the short and the long piece
Substitute 2x - 5 for y in [tex]x + y = 40[/tex]
[tex]x + 2x - 5 =40[/tex]
[tex]3x - 5 =40[/tex]
Add 5 to both sides
[tex]3x =45[/tex]
Divide both sides by 3
[tex]x =15[/tex]
Substitute 15 for x in [tex]y =2x - 5[/tex]
[tex]y =2 \times 15 -5[/tex]
[tex]y =30 -5[/tex]
[tex]y =25[/tex]
Hence, the shorter piece is 15 feet, while the longer piece is 25 feet

Suppose that 2 balls are chosen without replacement from an urn containing 5 white and 8 red balls. Let X1 equal 1 if the 1st ball selected is red, and let it equal 0 otherwise. Let X2 equal 1 if the 2nd ball selected is red, and let it equal 0 otherwise. (i) Give the joint probability mass function of X1 and X2. (ii) Are X1 and X2 independent
Answer:
The probability mass function :
P(X1 = 1, X2 = 1) = 5/13 * 4/12 = 5/39
P(X1 = 1, X2 = 0) = 5/13 * 8/12 = 10/39
P(X1 = 0, X2 = 1) = 8/13 * 5/12 = 10/39
P(X1 = 0, X2 = 0) = 8/13 * 7/12 = 14/39
Step-by-step explanation:
Given :
Number of white balls = 5
Number of red balls = 8
Total number of balls = (5 + 8) = 13
P(X1 = 1, X2 = 1) = 5/13 * 4/12 = (5/13 * 1/3) = 5/39
P(X1 = 1, X2 = 0) = 5/13 * 8/12 = (5/13 * 2/3) =10/39
P(X1 = 0, X2 = 1) = 8/13 * 5/12 = (2/13 * 5/3) =10/39
P(X1 = 0, X2 = 0) = 8/13 * 7/12 =(2/13 * 7/3) = 14/39
