Pre image ABCD was dilated to produce image A’B’C’D why is the scale factor from the pre image? Enter your answer in the box as a fraction
The scale factor of the dilation from ABCD to A′B′C′D′ is 3.
Step-by-step explanation:
Step 1:
In the pre-image ABCD, the length of one of the sides is given as 14 units.
For the other shape A′B′C′D′, the same side as the previous shape is given as 8 units.
Step 2:
To determine the scale factor, we divide the measurement after scaling by the same measurement before scaling.
In this case, it is the given length of the sides CD and C′D′.
So the scale factor = [tex]\frac{C^{1} D^{1} }{CD} = \frac{8}{14} = \frac{4}{7} .[/tex]
So the shape ABCD is dilated by a scale factor of [tex]\frac{4}{7}[/tex] to produce the shape A′B′C′D′.

James has 4 test scores of 82, 77, 75 and 84. What score does James need on the next test to
have an average of 80? State what x represents, state the equation, and then state the answer.
Answer:
average = sum of observations/number
80=400/5
Therefore, the sum of the scores has to equal 400.
Step-by-step explanation:
400-(82+77+75+84)=x
400-(318)=x
x=82
That is the minimum score needed.

(May someone help me?)A store sold 6 and 1/5 cases of juice on Friday and 4 and 4/5 cases of juice on Saturday. How many more cases of juice did the store sell on Friday then on Saturday?
Final answer:
The store sold 1 and 2/5 more cases of juice on Friday than on Saturday.
Explanation:
To determine how many more cases of juice the store sold on Friday than on Saturday, we need to subtract the number of cases sold on Saturday from the number of cases sold on Friday.
Friday's sales: 6 and 1/5 cases
Saturday's sales: 4 and 4/5 cases
We convert these mixed numbers to improper fractions to make the subtraction easier:
6 and 1/5 = (6 × 5 + 1)/5 = 31/5 cases4 and 4/5 = (4 × 5 + 4)/5 = 24/5 casesNow we subtract the two fractions:
(31/5) – (24/5) = 7/5 cases
Convert the improper fraction back to a mixed number:
7/5 = 1 and 2/5 cases
So, the store sold 1 and 2/5 more cases of juice on Friday than on Saturday.

y=mx+b can someone break this down for me and help me understand it?
Answer:
y=mx+b broken down is in the step by step explanation.
Step-by-step explanation:
y=mx+b is the y intercept formula.it is mostly used for slopes.
y is usually equal to the total,or final answer.it is the start.
m is equal to the slope.in the formula.it can also be used as the rise over run,which means the top number is the amount of units you go up for rise,and run is the bottom number which is the amount of units you move to the right.if it is negative,you move the opposite ways.if it is a single number,the bottom number can be 1.
x is equal to the number you multiply m,or the slope by.
b is equal to where you start on the vertical line in the graph.a way to remember it is horizontal is like a horizon,it’s flat.
Which of the following lines is perpendicular
to the equation given below?
y=-2x+8
The equation of the line perpendicular to y = -2x + 8 is y = 1/2x + 8.
A line is perpendicular to another line if their slopes are negative reciprocals of each other. The slope of the line y = -2x + 8 is -2, so the slope of a line perpendicular to it would be 1/2.
Of the above choices, only line (C) has a slope of 1/2. Therefore, the equation of the line perpendicular to y = -2x + 8 is y = 1/2x + b, where b is the y-intercept.
To find the value of b, we can substitute a point on the line y = -2x + 8 into the equation y = 1/2x + b. For example, the point (0, 8) lies on the line y = -2x + 8. Substituting this point into the equation y = 1/2x + b, we get:
8 = 1/2 * 0 + b
b = 8
Therefore, the equation of the line perpendicular to y = -2x + 8 is y = 1/2x + 8.

FGHI is a parallelogram. Find the measure of angle I.
*show your work please*
Answer:
I = 130
Step-by-step explanation:
The sum of all four angles in a four-sided closed shape will ALWAYS be equivalent to 360 degrees. Also, the opposite angles of a parallelogram will ALWAYS be equivalent. This means F = H.
To begin, the measure of F, y + 7, and the measure of H, 3y - 79, are equal. This equation looks like: y + 7 = 3y - 79
Now subtract y from both sides: 7 = 2y - 79
Add 79 to both sides: 86 = 2y
And divide both sides by 2: 43 = y
Now that you have the value of y, plug 43 into y and solve for both equations:
43 + 7 = 3(43) - 79
50 = 129 - 79
50 = 50
So now we know that the measure of angles F and H are 50. 50 + 50 is 100.
Since we know that the sum of all four sides must be equivalent to 360. subtract 100 from 360 to get the sum of the measures of angles I and G:
360 - 100 = 260
So now 260 must equal I + G. Since I and G must be equivalent, just divide 260 by 2 and you have your answer: 260/2 = 130

What must be the length of ZY in order for ZY to be tangent to circle X at point Y?
14 units
15 units
16 units
17 units
Answer:
15 unitsStep-by-step explanation:
In the image attached you can notice that line ZY is tangent at point Y.
Remember that the radius is always perpendicular to tangents, by definition, that means [tex]XY \perp ZY[/tex].
That means [tex]\triangle XYZ[/tex] is a right triangle where [tex]\angle Y = 90\°[/tex].
All these facts are deducted form having ZY as a tangent.
We know by given that
[tex]XZ=8+9=17[/tex]
[tex]XY=8[/tex], becaus it's the radius.
Using Pythagorean Theorem
[tex]17^{2} =8^{2}+ZY^{2}[/tex]
Solving for [tex]ZY[/tex]
[tex]ZY=\sqrt{17^{2} -8^{2} } \\ZY=\sqrt{289-64}\\ ZY=\sqrt{225}\\ ZY=15[/tex]
Therefore, the length of ZY must be 15 units to be tangent to circle X.

The total rainfall in March was 3.6 inches. In April, the total rainfall was as 1.4 times as much. What was the total rainfall in April?
Answer:
5.04 inches
Step-by-step explanation:
because the total rainfall in March was 3.6 inches and if the total rainfall in April was 1.4 times as much then you would take the total rainfall in March which was 3.6 inches and multiply that by 1.4 because it says the amount in April was 1.4 times as much.
The total rainfall in March was 3.6 inches. In April, the total rainfall was 1.4 times as much. The total rainfall in April is calculated by multiplying the March rainfall of 3.6 inches by 1.4, resulting in a total April rainfall of 5.04 inches.
Explanation:The total rainfall in March was 3.6 inches. In April, the total rainfall was 1.4 times as much. To calculate the total rainfall in April, you multiply the March rainfall by 1.4. So, the calculation you'd do is 3.6 inches (March rain) times 1.4. This gives you 5.04 inches of rainfall in April. So, the total rainfall in April was 5.04 inches.

A pack of 100 recordable DVDs contains 5 defective disks. You select four disks . What is the probability of selecting at least three non-defective disks
Answer: 3% (3/100), 4% (1/25), and 5% (1/20)
Step-by-step explanation:
So, there are 100 recordable DVDs, and 5 are defective. The way you find the answer is by dividing 100 by 100, which equals one. That means you have a one percent chance to select one random DVD. But, since you need to find the probability of selecting at least three non-defective DVDs, you would need to multiply 1 by 3, 4 or 5 to get the percentages for you probability.
Final answer:
The probability of selecting at least three non-defective disks from a pack with 5 defective ones among a total of 100 is found by summing the probabilities of selecting exactly three non-defective disks plus the probability of selecting all four non-defective disks.
Explanation:
The question asks for the probability of selecting at least three non-defective disks from a pack that contains 100 recordable DVDs, with 5 being defective. To solve this, we consider the scenarios where 3 or 4 non-defective disks are chosen out of the 4 disks we pick. We will calculate these probabilities using the hypergeometric distribution, which is apt for scenarios where we have a finite population without replacement.
Calculating the Probability:
Let X represent the number of non-defective disks selected.
There are two outcomes where at least three disks are non-defective: when exactly 3 are non-defective (one is defective) or when all 4 are non-defective.
Probability of selecting 3 non-defective disks and 1 defective disk (X = 3):
P(X = 3) = [number of ways to choose 3 non-defective from 95]
imes [number of ways to choose 1 defective from 5] / [number of ways to choose 4 from 100].
Probability of selecting 4 non-defective disks (X = 4):
P(X = 4) = [number of ways to choose 4 non-defective from 95] / [number of ways to choose 4 from 100].
The total probability of selecting at least three non-defective disks is the sum of these two probabilities: P(X = 3) + P(X = 4).
