Which question best describes the diagram above? Answer the question. 120 is 25% of what? 25% of 120 is what? 6 is what percent of 120? 120 is what percent of 25?
Answer:
1. 480
2. 30
3. 5
4. 480%
Step-by-step explanation:
1.
25% = 120
100% = 120 x 4 = 480
2.
100% = 120
25% = 120 : 4 = 25
3.
120 = 100%
6 = 6/120 x 100 = 5%
4.
25 = 100%
120 = 120/25 x 100 = 480%
use your answer in part (a) to find the two values of m for which (m-2)2 -4(m-2)+2=0
Answer:
Step-by-step explanation:
Replace m - 2 with x. Then we have x^2 - 4x + 2 = 0.
Completing the square, we get x^2 - 4x + 4 - 4 + 2 = 0, or
x^2 - 4x + 4 - 2 = 0, or
(x - 2)^2 - 2 = 0, or (x - 2)^2 = 2
Solve for x: Take the square root of both sides. Then:
x - 2 = ±√2 and x = 2 + √2 and x = 2 - √2
But x = m - 2; therefore, x = m - 2 = 2 - √2. Solving for m, we get
m = 4 - √2.
Also: m - 2 = 2 + √2 leads to m = 4 + √2.
The given equation is true for these two values of m.

Work out the size angle BCD
By using the fact that the interior angles should add up to 360°, we will see that:
C = 142°
How to find the missing angle?We know that for any polygon of N sides, the sum of the interior angles is equal to:
S = (N - 2)*180°
In this case, the polygon has 4 sides, then:
S = (4 -2)*180° = 360°
Then we can write the equation:
A + B + C + D = 360°
Replacing the known angles we get:
68° + 43° + C + 107° = 360°
And now we can solve this for C.
C = 360° - 107° - 43° - 68°
C = 142°
That is the measure of the angle BCD.

For 1-4, write "yes" or "no" to describe whether or not the line is a good trend line. Explain.
On solving the provided question we can say that - and a lines need only two points to drawn; so, yes we can draw a line
what is a line?A line is an endlessly long object without breadth, depth, or curvature in geometry. Consequently, a line is a one-dimensional entity, while it may also exist in two-, three-, and more-dimensional regions. In common use, a line segment with two points serving as its ends is referred to as a line. A line is a single-dimensional, straight form with no thickness that can go on forever in both directions. To indicate that a line has no "wobble" anywhere along its length, it is frequently referred to as a straight line or an ancient accurate line (Casey 1893)

A beehive contains 5 gallons of honey. A beekeeper removes 4 gallons, 1 pint, and 2 ounces. How much honey remains in the beehive?
how many quarts_____ and how many ounces_____
Answer:
3 quarts and 14 ounces of honey remain in the beehive.
Step-by-step explanation:
Pint = 16 ounces
Gallon = 128 ounces
Quart = 32 ounces
So, we start with a total of 640 ounces of honey. The beekeeper removes 530 ounces, leaving 110 behind. 32 ounces in a quart means that there are 3 full quarts in the hive as well as 14 ounces.
Christopher has 95 toy cars. He arranges his cars in 5 equal rows. Write numbers in the boxes to complete the partial quotient model and the equation to find the number of cars in each row. 95 + 5 = cars
The number of boxes to complete the partial quotient model is found to be as 19 cars .
On dividing 95 from 5 we will get 19 as the quotient.
95 / 5 = 19
The quotient is the number that is produced when two integers are divided. It is the outcome of the division process , when we divide a number from another the result is known as quotient.
In arithmetic division, four primary terms are used which are divisor, dividend, quotient, and remainder. In this post, each phrase will be defined and shown using examples.
Dividend = Divisor + Quotient + Remainder
If the divisor is not able to completely divide the dividend then it leaves a remainder.

Suppose that a recent poll found that 47% of adults believe that the overall state of moral values is poor. For 350 randomly selected adults, compute the mean and standard deviation of the random variable X, the number of adults who believe that the overall state of moral values is poor. What is the mean of X and the standard deviation of X?
Answer:
The mean of X is 164.5 and the standard deviation is 9.34.
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they believe that the overall state of moral values is poor, or they do not. The probability of an adult believing this is independent of any other adult, which means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
The standard deviation of the binomial distribution is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
Suppose that a recent poll found that 47% of adults believe that the overall state of moral values is poor.
This means that [tex]p = 0.47[/tex]
350 randomly selected adults
This means that [tex]n = 350[/tex]
What is the mean of X and the standard deviation of X?
Mean:
[tex]E(X) = np = 350*0.47 = 164.5[/tex]
Standard deviation:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{350*0.47*0.53} = 9.34[/tex]
The mean of X is 164.5 and the standard deviation is 9.34.

What is a formula for the nth term of the given sequence?
20,50, 125...
Answer:
a(n) = 20*2.5^(n - 1)
Step-by-step explanation:
Note that 50 is 2.5 times 20, and that 125 is 2.5 times 50. Thus the common factor is 2.5. The formula for the nth term is
a(n) = a(1)*r^(n - 1) => a(n) = 20*2.5^(n - 1)

Evaluate each expression when a = -4 and b = 3
1.) ab
2.) 2a + 3b
2.) 2(a - b)
1) -12
ab is a times b. We plug in the numbers (-4)*(3) which equals -12.
2) 1
We plug in -4 for a, and 3 for b into the equation.
We get 2(-4) + 3(3)
2*-4 is -8. 3*3 is 9. We add them both, and -8+9 equals 1.
3) -14
We plug in -4 for a, and 3 for b into the equation.
2(-4-3)
-4-3 is -7. -7*2 equals -14.

The trigonometric ratios for the triangle in this problem are given as follows:
sin(A) = a/c.cos(A) = b/c.tan(A) = a/b.sin(B) = b/c.cos(B) = a/c.tan(B) = b/a.What are the trigonometric ratios?The three trigonometric ratios are defined as follows:
Sine of angle = length of opposite side divided by the length of the hypotenuse.Cosine of angle = length of adjacent side divided by the length of the hypotenuse.Tangent of angle = length of opposite side divided by the length of the opposite side.The sides are connect by the right angle, of 90 degrees, while the hypotenuse is the straight line segment that connects the endpoints of each of the sides.

What does y 3x 3 look like on a graph?
On a graph, y 3x 3 would be a line that is 3 units below the line y = 3x. It would have the same slope but lower y-intercept.
To graph y 3x 3, we can first graph y = 3x. To do this, we can pick any two points along the line and plot them. For example, if we choose (0,0) and (1,3), the line would look like this:
(0,0) -------------------------- (1,3)
Now, to graph y 3x 3, we want to move the line 3 units down. Therefore, the new points that we plot should be (0,-3) and (1,0). The graph should look like this:
(0,-3) -------------------------- (1,0)
This line is 3 units below the line y = 3x. It has the same slope, but a lower y-intercept.

7. The terminal side of theta, and angle in standard position, intersects the unit circle at
P(-) What is the value of csc?
Complete question is;
The terminal side of angle θ in standard position, intersects the unit circle at P(-10/26, -24/26). What is the value of csc θ?
Answer:
csc θ = -13/12
Step-by-step explanation:
We know that in a unit circle;
(x, y) = (cos θ, sin θ)
Since the the terminal sides intersects P at the coordinates P(-10/26, -24/26), we can say that;
cos θ = -10/26
sin θ = -24/26
Now we want to find csc θ.
From trigonometric ratios, csc θ = 1/sin θ
Thus;
csc θ = 1/(-24/26)
csc θ = -26/24
csc θ = -13/12

What range of values is not a possible scale factor (k)?
A) k 1
D) all are possible
A range of values which is not a possible for scale factor (k): k = 0
We know that the scale factor is the number (also called the conversion factor) which is used to change the size of a figure without changing its shape.
It is used to expand or compress the size of an object.
The scale factor formula is:
Scale factor = Dimensions of the transformed shape ÷ Dimensions of the original shape
If the scale factor k > 1, the object is enlarged.
If the scale factor is 0< k <1, the object is compressed.
If the scale factor is k = 1, the shape of object remains the same.
And the scale factor cannot be zero.
