(11x-28)(7x-8) find x
After solving (11x-28)=(7x-8) the value of x is 5
Given:
(11x-28) = (7x-8)
11x - 28 - 7x + 8 = 0
(11x - 7x) - 28 + 8 = 0
4x - 28 + 8 = 0
4x - 20 = 0
4x = 20
Dividing by 4 on both sides we get,
4x/4 = 20/4
x = 20/4
x = 5
Therefore after solving (11x-28)=(7x-8) the value of x is 5.

At a convenience store, you have a choice of five diet drinks, 10 regular drinks, six bags of fat-free chips, and 10 bags of regular chips. What is the probability that you will buy a regular drink and a regular bag of chips?
Answer:
I guess that the purchase is at random, then let's see the possible options:
5 diet drinks.
10 regular drinks.
Total drinks = 15
6 bags of fat-free chips
10 bags of regular chips.
Total chips = 16.
Probability of buying at random, a regular drink is equal to the number of regular drinks divided the total number of drinks:
p1 = 5/15 = 1/3
Probability of buying at random a regular bag of chips, we use the same reasoning as before.
p2 = 6/16 = 3/8
The joint probability will be equal to the product of the individual probabilities:
P = p1*p2 = (1/3)*(3/8) = 1/8.

A company currently has an advertisement that covers a bill board that is 30 ft wide by 70 ft high. The company wants to reduce the same advertisement to fit on a new billboard that is 25ft wide by 40 ft high. What are the dimensions of the largest advertisement that will fix on the billboard without cropping the advertisement
Given :
A company currently has an advertisement that covers a bill board that is 30 ft wide by 70 ft high. The company wants to reduce the same advertisement to fit on a new billboard that is 25 ft wide by 40 ft high.
To Find :
The dimensions of the largest advertisement that will fix on the billboard without cropping the advertisement.
Solution :
Area of original bill board :
[tex]A_i=30\times 70 = 2100\ ft^2[/tex]
Area of new bill board :
[tex]A_f=25\times 40 = 1000\ ft^2[/tex]
Since, new bill board can be completely fitted in original bill board as its length and breadth both are smaller than that.
So, the dimensions of the largest advertisement that will fix on the billboard without cropping the advertisement is equal to 1000 ft².
Hence, this is the required solution.

A right triangle with angle measures of 45, 45, 90 degrees undergoes a reflection, rotation, and translation. Determine whether the angle measure of the image of the triangle are 45, 45 and 90 degrees after each transformation. Choose yes or no.
Answer:
Reflection - Yes
Rotation - Yes
Translation - Yes
Step-by-step explanation:
After all 3 different transformations, the angle measures of the triangle will stay the same, at 45, 45, and 90 degrees.
This is because these 3 transformations do not change the shape of the triangle. They only change the orientation and placement of the triangle.
So, the angle measures will still be 45, 45, and 90 degrees after each transformation.
Answer:
Yes, the correct answer to this question is Yes.

type your answer...
Answer:
[tex] \huge \: x = - 5417.33[/tex]
Step-by-step explanation:
[tex]0.75 (x + 200) = 150.5 (2 – 28) \\ [/tex]
Expand the terms and simplify
That's
[tex]0.75x + 150 = 301 - 4214 \\ 0.75x + 150 = - 3913[/tex]
Subtract 150 from both sides of the equation
[tex]0.75x + 150 - 150 = - 3913 - 150 \\ 0.75x = - 4063[/tex]
Divide both sides by 0.75
[tex] \frac{0.75x}{0.75} = - \frac{4063}{0.75} \\ x = - 5417.333333[/tex]
We have the final answer as
x = - 5417.33Hope this helps you
Items are inspected for flaws by two quality inspectors. Both inspectors inspect every item and the probability that an item has a flaw is 0.1. If a flaw is present,it will be detected by the first inspector with probability 0.92, and by the second inspector with probability 0.7. If an item does not have a flaw, it will be passed by the first inspector with probability 0.95 and by the second inspector with probability 0.8. Assume the inspectors function independently.
(a) If an item has a flaw, what is the probability that it will be found by at least one of the two inspectors?
(b) If an item is passed by the first inspector, what is the probability that it actually has a flaw?
(c) What is the probability that the two inspectors draw different conclusions on the same item?
(d) If an item is passed by both inspectors, what is the probability that it actually has a flaw?
Answer:
a)0.976
b)0.00926
c)0.2402
d)0.35
Step-by-step explanation:
Let [tex]X_i[/tex] be an item passed by inspector i
Let Y be the event that there is a fault in an item
The probability that an item has a flaw is 0.1 i.e. P(Y)=0.1
If a flaw is present ,it will be detected by the first inspector with probability 0.92 i.e.[tex]P(\bar{X_1}|Y)=0.92[/tex]
So, [tex]P(X_1|Y)=1-0.92=0.08[/tex]
If a flaw is present ,it will be detected by the second inspector with probability 0.7 i.e.[tex]P(\bar{X_2}|Y)=0.7[/tex]
So,[tex]P(X_2|Y)=1-0.7=0.3[/tex]
If an item does not have a flaw, it will be passed by the first inspector with probability 0.95 i.e. [tex]P(X_1|\bar{Y}) = 0.95[/tex]
So, [tex]P(\bar{X_1}|\bar{Y}) = 1-0.95=0.05[/tex]
If an item does not have a flaw, it will be passed by the second inspector with probability 0.8 i.e. [tex]P(X_2|\bar{Y}) = 0.8[/tex]
So, [tex]P(\bar{X_2}|\bar{Y}) = 1-0.8=0.2[/tex]
a)P(found by atleast one inspector | It has flaw )=1-P(found by none inspector | It has flow )
P(found by atleast one inspector | It has flaw )=[tex]1-P(X_1|Y) P(X_2|Y)[/tex]
P(found by atleast one inspector | It has flaw )=[tex]1-0.08 \times 0.3[/tex]
P(found by atleast one inspector | It has flaw )=0.976
Hence the probability that it will be found by at least one of the two inspectors if it has flaw is 0.976
b)[tex]P(Y|X_1)=\frac{P(X_1|Y) P(Y)}{P(X_1|Y) P(Y)+P(X_1|\bar{Y}) P(\bar{Y})}[/tex]
[tex]P(Y|X_1)=\frac{0.08 \times 0.1}{0.08 \times 0.1+0.95 \times 0.9}=0.00926[/tex]
C)P( two inspectors draw different conclusions on the same item)=[tex]P(X_1 \cap \bar{X_2} \cap Y)+P(\bar{X_1} \cap X_2 \cap Y)+P(X_1 \cap \bar{X_2} \cap \bar{Y})+P(\bar{X_1} \cap X_2 \cap \bar{Y})[/tex]
P( two inspectors draw different conclusions on the same item)=0.2402
D)
[tex]P(Y|(X_1 \cap X_2))=\frac{P(Y \cap X_1 \cap X_2)}{P(X_1 \cap X_2)}\\P(Y|(X_1 \cap X_2))=\frac{P(Y \cap X_1 \cap X_2)}{P(X_1 \cap X_2 \cap Y)+P(X_1 \cap X_2 \cap \bar{Y})}\\P(Y|(X_1 \cap X_2))=0.35[/tex]

The low temperatures in two cities are being compared. In City 1, the range in temperature is 20°F and the IQR is 7°F.
In City 2, the range in temperature is 15°F and the IQR is 7°F.
What might you conclude about the cities based on the ranges and interquartile ranges?
B.The weather pattern in City 2 is more consistent than the weather pattern in City 1
explanation:
Range and interquartile range (IQR) measures the spread of data. Range measure the overall spread and IQR measures spread in 50% of data.
Range is calculated by differencevof maximum and minimum value whereas IQR is calculated by difference of First quartile and third quartile.
Since, the range and IQR is less for City 2 as compared to City 1.
Thus ,weather pattern of City 2 is more consistent as compared to City 1.

Answer:
18-726;615+8876-9987The point (8, 12) was dilated to become point (2, 3). What was the scale factor?
Answer:
The scale factor is 1/4
Step-by-step explanation:
Here, we are interested in finding the scale factor that helped convert the first point to the second.
Hence, what turned (8,12) to (2,3)
What we shall do here is to simply divide term 2 by term i.e
That would be 2/8 or 3/12 = 1/4
The scale factor was 1/4.
Given that,
The point (8, 12) was dilated to become point (2, 3).
We have to determine,
What was the scale factor?
According to the question,
Scale factors are closely related to the concepts of ratio and proportions.
In ratio and proportions, we multiply or divide a given amount to form a new quantity.
The point (8, 12) was dilated to become point (2, 3).
Therefore,
The scale factor was,
[tex]\rm Scale\ factor = \dfrac{New \ point \ lies \ on \ axis}{Old \ point \ lies \ on \ axis}[/tex]
Substitute the points in the formula for the x-axis,
[tex]\rm \rm Scale\ factor = \dfrac{New \ point \ lies \ on \ x-axis}{Old \ point \ lies \ on \ x-axis}\\\\Scale\ factor = \dfrac{2}{8}\\\\Scale\ factor = \dfrac{1}{4}\\\\[/tex]
And substitute the points in the formula for the y-axis,
[tex]\rm \rm Scale\ factor = \dfrac{New \ point \ lies \ on \ y-axis}{Old \ point \ lies \ on \ y-axis}\\\\Scale\ factor = \dfrac{3}{12}\\\\Scale\ factor = \dfrac{1}{4}\\\\[/tex]
Hence, The scale factor was 1/4.
