Answer:Decreasing
Step-by-step explanation:
The line is going down.
The given graph is decreasing. The correct option is A.
Increasing graph: A graph is considered increasing if it moves upwards as you move from left to right along the x-axis. In other words, the y-values increase as the x-values increase. This is often represented by a positive slope, where the line or curve ascends as it extends to the right.
Decreasing graph: A graph is considered decreasing if it moves downwards as you move from left to right along the x-axis. In this case, the y-values decrease as the x-values increase. It is represented by a negative slope, where the line or curve descends as it extends to the right.
Constant graph: A graph is considered constant if it remains flat and does not rise or fall as you move along the x-axis. The y-values do not change with increasing x-values, and this is represented by a horizontal line.
In given figure the line goes to downwards and the vales of y is decreasing for the increasing values of x.
Hence, the given graph is decreasing. The correct option is A.

Suppose the true proportion of high school juniors who skateboard is 0.18. If many random samples of 250 high school juniors are taken, by how much would their sample proportions typically vary from the true proportion?
0
0.0006
0.024
0.148
6.07
Answers
Answer:
0.024
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes 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.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
Suppose the true proportion of high school juniors who skateboard is 0.18.
This means that [tex]p = 0.18[/tex]
Samples of 250 high school juniors are taken
This means that [tex]n = 250[/tex]
By how much would their sample proportions typically vary from the true proportion?
This is the standard error, so:
[tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
[tex]s = \sqrt{\frac{0.18*0.82}{250}}[/tex]
[tex]s = 0.024[/tex]
So 0.024 is the answer.
Given 15=3(2x+4)−3
Prove x=1
Complete the proof. Provide reasons for 1-6 below. Make sure to number your answers.
Answers
we start with the inside of the para thesis so multiply 2•1 which gives us 2 and we add 4 which gives us 6
now we have 15=3(6)-3
we multiply the 3 and 6 and we get 18
Now we have 15=18-3 so we subtract 18-3 and we get 15
15=15 is the product
The value of x in the expression 15 = 3(2x + 4) - 3 is 1.
What is expression?A number, a variable, or a combination of numbers and variables and operation symbols is called expression.
According to the given question.
We have an expression
[tex]15 = 3(2x+ 4) -3[/tex]
Solve the above expression for x.
Step 1: open the parentheses
[tex]15 = 3(2x + 4) -3[/tex]
⇒ [tex]15 = 6x + 12 -3[/tex]
Step 2: simplify the above expression.
[tex]15 = 6x + 9[/tex]
Step 3: subtract 9 to the both the sides
[tex]15 - 9 = 6x + 9 -9[/tex]
⇒[tex]6 = 6x[/tex]
Step 4: Divide both the sides by 4
⇒ [tex]\frac{6}{6} =\frac{6x}{6}[/tex]
⇒ [tex]x = 1[/tex]
Hence, we proved that x = 1 for the above expression.

During a sale, a store offered 35% discount on a particular couch that was originally priced at $390. After the sale, the discount price of the camera was increased by 35%. What was the price of the couch after this increase? Round to the nearest cent.
Answers
Answer:
$342.23
Step-by-step explanation:
35/100 x $390 = $136.50
Price of couch after 35% discount
= $390 - $136.50
= $253.50
35/100 x $253.50 = $88.725
Price of couch after the 35% increase
= $253.50 + $88.725
= $342.225
= $342.23 (round off to nearest cents)

so the other angle is
52
so we just use the formulas
and
Side a = 26.56371
Side b = 43.14662
Side c = 34
so the side with a x on it is 26.6
so know we have to do the same thing but not including the top part
ok so the side with x on it is 18.8
so 26.6-18.8=7.8

Kathy plans to purchase a car that depreciates
(loses value) at a rate of 14% per year. The initial
cost of the car is $21,000. Which equation
represents the value, v, of the car after 3 years?
1) v = 21,000(0.14)
2) v = 21,000(0.86)
3) v= 21,000(1.14)
4) v= 21,000(0.86)(3)
Answers
Answer:
Step-by-step explanation:
The standard form equation for this type of problem is
[tex]y=a(b)^x[/tex] where a is the initial value, b is the rate of depreciation, and x is the number of years in question. Because the value of the car is going down, b can also be written as (1 - r) where r is the rate of depreciation. For us, then, the equation will look like this:
[tex]y=a(1-r)^x[/tex] and filling in:
[tex]y=21000(1-.14)^3[/tex] which in simplified form is
[tex]y=21000(.86)^3[/tex] which I'm assuming is how choice 4 should look.
What is the value of x in the diagram?
Answers
Answer:
x=5
Step-by-step explanation:
Since this is a right triangle, we can use the pythagorean theorem
a^2 + b^2 = c^2
x^2+ ( 2x+2)^2 = (2x+3)^2
FOIL the squared terms
x^2 +(4x^2 + 4x+4x+4) = 4x^2 + 6x+6x +9
Combine like terms
5x^2+8x +4 = 4x^2 +12x +9
Subtract 4x^2 +12x +9 from each side
5x^2+8x +4 -4x^2 -12x -9= 4x^2 +12x +9-4x^2 -12x -9
x^2 -4x -5 =0

Answers
Answer:
Option A
Step-by-step explanation:
Angular velocity of an object is defined by,
Angular velocity (w) = [tex]\frac{\triangle \theta}{\triangle t}[/tex]
Here, Δθ = Change in angle of rotation
Δt = Duration or time
In this question Δθ = [tex]\frac{7\pi }{2}[/tex] radians and Δt = 24 seconds
Therefore, angular velocity = [tex]\frac{\frac{7\pi }{2} }{24}[/tex]

A car owner decides to upgrade from tires with a diameter of 24.3 in to tires with a diameter of 26.1 in. If she doesn't update the onboard
computer, how fast will she actually be traveling when the speedometer reads 65 mph?
Although we want to solve for the linear speed of the upgraded tires, we do not have enough information for that. To fill up the formula v = rw, we only have the upgraded tires
r. but we do not know yet their w. However, since the speedometer counts rotations per hour and uses that to get the v of older tires, we can use that information to find the w
of the upgraded tires. Thus, let us solve first for w using the radius of the old tires and the reading of the speedometer.
Note: Do not forget that you are given the diameter and must still use that to get the radius. Also, do not forget that the diameter is given in inches, and you must convert that to miles, in order to be able to
cancel the time units. (1 mi = 63, 360 in)

[tex](x^{2} +x-3): (x^{2} -4)\geq 1[/tex]
Answers
Answer:
[tex]x>2[/tex]
Step-by-step explanation:
When given the following inequality;
[tex](x^2+x-3):(x^2-4)\geq1[/tex]
Rewrite in a fractional form so that it is easier to work with. Remember, a ratio is another way of expressing a fraction where the first term is the numerator (value over the fraction) and the second is the denominator(value under the fraction);
[tex]\frac{x^2+x-3}{x^2-4}\geq1[/tex]
Now bring all of the terms to one side so that the other side is just a zero, use the idea of inverse operations to achieve this:
[tex]\frac{x^2+x-3}{x^2-4}-1\geq0[/tex]
Convert the (1) to have the like denominator as the other term on the left side. Keep in mind, any term over itself is equal to (1);
[tex]\frac{x^2+x-3}{x^2-4}-\frac{x^2-4}{x^2-4}\geq0[/tex]
Perform the operation on the other side distribute the negative sign and combine like terms;
[tex]\frac{(x^2+x-3)-(x^2-4)}{x^2-4}\geq0\\\\\frac{x^2+x-3-x^2+4}{x^2-4}\geq0\\\\\frac{x+1}{x^2-4}\geq0[/tex]
Factor the equation so that one can find the intervales where the inequality is true;
[tex]\frac{x+1}{(x-2)(x+2)}\geq0[/tex]
Solve to find the intervales when the equation is true. These intervales are the spaces between the zeros. The zeros of the inequality can be found using the zero product property (which states that any number times zero equals zero), these zeros are as follows;
[tex]-1, 2, -2[/tex]
Therefore the intervales are the following, remember, the denominator cannot be zero, therefore some zeros are not included in the domain
[tex]x\leq-2\\-2<x\leq-1\\-1\leq x<2\\x>2[/tex]
Substitute a value in these intervales to find out if the inequality is positive or negative, if it is positive then the interval is a solution, if it is negative then it is not a solution. This is because the inequality is greater than or equal to zero;
[tex]x\leq-2[/tex] -> negative
[tex]-2<x\leq-1[/tex] -> neagtive
[tex]-1\leq x <2[/tex] -> neagtive
[tex]x>2[/tex] -> positive
Therefore, the solution to the inequality is the following;
[tex]x>2[/tex]
