What can Slope be???????
Answer:
Slope = -5
Step-by-step explanation:
(x,y) ⇒ (13,11), (14,6), (15,1), (16,-4)
Pick any two points:
(x₁, y₁) and (x₂, y₂) ⇒ (15, 1) and (16, -4)
Use the slope formula:
⇒ y₂ - y₁/x₂ - x₁
⇒ -4 - 1/16 - 15
⇒ -5/1 = -5
Thus, the slope is -5.

the selling price of a product is $20 and the markup is $4 What percentage of the selling price does the markup represent
Answer:
20%
Step-by-step explanation:
The ratio of 20 to 4 can be simplified to 5:1, by switching it around, we get 1/5. 1/5 as a percentage can be expressed as 20%
Answer:
20%
Step-by-step explanation:
Given the following question:
20% of 20
To find the answer we will use the formula to calculate percentages.
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{20\times20}{100}[/tex]
[tex]20\times20=400[/tex]
[tex]400\div100=4[/tex]
[tex]=4[/tex]
20% of 20 is 4, which means your answer is "20%."

The average amount of time to finish this quiz is 26 minutes with a standard deviation of 1.2 minutes. What is the probability that you will finish this quiz in 23.84 minutes or less? Write your answer as a percentage with 2 decimals.
Answer:
What is the probability that you will finish this quiz in 23.84 minutes or less?
0.03593
Write your answer as a percentage with 2 decimals
= 3.59%
Step-by-step explanation:
The z score formula is given as:
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
Mean = 26 minutes
Standard deviation = 1.2 minutes.
The probability that you will finish this quiz in 23.84 minutes or less(≤) is calculated as:
z = (x-μ)/σ
z = 23.84 - 26/1.2
z = -1.8
Probability value from Z-Table:
P(x ≤ 23.84) = 0.03593
Converting to percentage
0.03593 × 100
= 3.593
Approximately to 2 decimal places = 3.59%
The following histogram shows the relative frequencies of the hieight recorded to the nearest inch of population of women the mean of the population is 64.97 inches and the standard deviation is 2.66 inches
The following histogram shows the relative frequencies of the height recorded to the nearest inch of population of women the mean of the population is 64.97 inches and the standard deviation is 2.66 inches
(a) Based on the histogram, what is the probability that the selected woman will have a height of at least 67 inches? Show your work
Answer:
0.22268
Step-by-step explanation:
z-score is z = (x-μ)/σ,
where x is the raw score
μ is the population mean
σ is the population standard deviation.
(a) Based on the histogram, what is the probability that the selected woman will have a height of at least 67 inches? Show your work
At least means equal to or greater than 67 inches
z = 67 - 64.97/2.66
z = 0.76316
P-value from Z-Table:
P(x<67) = 0.77732
P(x>67) = 1 - P(x<67) = 0.22268
The probability that the selected woman will have a height of at least 67 inches is 0.22268

75 less than four times a number is equal to the number. what is the number
Answer:
number = 25
Step-by-step explanation:
❖ First, let's set up the equation.
"75 less than four times a number" means 4x - 75"is equal to the number" means = n (n = number)n = 4n - 75Solving
Step 1: Subtract 4n from both sides
[tex]n-4n=4n-75-4n[/tex] [tex]-3n=-75[/tex]Step 2: Divide both sides by -3.
[tex]-3n/-3=-75/-3[/tex] [tex]n = 25[/tex]Step 3: Check if solution is correct.
[tex]25=4(25)-75[/tex] [tex]25=100-75[/tex] [tex]25=25[/tex]Therefore, the number is 25.

what percent of 20 is 18?
Answer:
90%
Step-by-step explanation:
A fraction consists of two numbers and a fraction bar:
18/20
The number above the bar is the numerator: 18
The number below the bar is the denominator: 20
Divide the numerator by the denominator to get fraction's value:
Val = 18 ÷ 20

How do you do this question?
This series diverges by the limit test (some books may call it the nth term test).
Recall the limit test is the idea if the sequence doesn't converge to 0, then the series diverges.
In this case, the sequence converges to n/(7n) = 1/7 since all we are about are the leading terms when n gets very large.
After some very large n value, we're effectively adding on 1/7 or very close to it, each time. The infinite sum does not approach a fixed value. It keeps growing forever.

f(x) = 2x-3 and g(x)=2x+1
Find (f+g) (x)
Answer:
(f + g)(x) = 4x - 2
Step-by-step explanation:
This problem is asking us to find the value of (f + g)(x).
This means that we will need to add the values of f(x) and g(x) together.
Therefore, the values that are defined for these two functions will simply be conjoined by addition.
Steps
Step 1: Place the value of f(x) in parentheses ⇒ (2x - 3). Then, do the same for g(x) ⇒ (2x + 1).
Step 2: Combine any like terms. Start with the terms that are not constants (variables with coefficients) and then combine constants.
Step 3: Simplify as much as possible.
Work Shown
[tex]$\tex$ f(x) = 2x - 3, g(x) = 2x + 1\\\\(f + g)(x) \ $\rightarrow$ \ f(x) + g(x)\\\\(2x - 3) + (2x + 1)\\\\\boxed{(4x - 2)}[/tex]
Therefore, (f + g)(x) = 4x - 2.

Two balls are placed in a box according to the following process: 1. A fair coin is tossed. A white ball is placed in the box if a head occurs, otherwise a red ball is placed in the box. 2. The fair coin is tossed again. A red ball is placed in the box if a tail occurs, otherwise a white ball is placed in the box. Balls are drawn from the box three times in succession (always with replacing the drawn ball back in the box). On all three occasions a red ball is drawn from the box. There are two pieces of information available: the process by which balls are placed in the box and the 3 observations of a ball drawn from the box. Making use of all relevant available information, what is the probability that both balls in the box are red
Answer:
The probability that both balls in the box are red given that all three occasions a red ball is drawn from the box is [tex]\frac{4}{5}[/tex]
Step-by-step explanation:
Let RRR be the event in which red Balls are drawn from the box three times in succession
Let rr be the event that two red balls are placed in a box
Let rw be the event the first red ball was placed and then white ball was placed
Let wr be the event the first white ball was placed and then red ball was placed
Let ww be the event that two white balls are placed in a box
Now we know that :
[tex]P(rr)=P(rw)=P(wr)=P(ww)=\frac{1}{4}[/tex]
Probability of getting red Balls three times in succession given that both are placed red balls in box:
[tex]P(RRR|rr)=1[/tex]
Probability of getting red Balls three times in succession given that one ball is red and another is white in a box
[tex]P(RRR|wr)=P(RRR|rw)=\frac{1}{2^3}=\frac{1}{8}[/tex]
Probability of getting red Balls three times in succession given that both are placed white balls in box:
[tex]P(RRR|ww)=0[/tex]
Now we are supposed to find the probability that both balls in the box are red given that all three occasions a red ball is drawn from the box i.e. P(rr|RRR)
So, we will use bayes theorem
[tex]P(rr|RRR)=\frac{P(RRR|rr) P(rr)}{P(RRR|rr) P(rr)+P(RRR|rw) P(rw)+P(RRR|wr) P(wr)+P(RRR|ww) P(ww)}\\P(rr|RRR)=\frac{1 \times \frac{1}{4}}{1 \times \frac{1}{4}+\frac{1}{8} \times \frac{1}{4}+\frac{1}{8} \times \frac{1}{4}+0 \times \frac{1}{4}}\\\\P(rr|RRR)=\frac{\frac{1}{4}}{\frac{5}{16}}\\\\P(rr|RRR)=\frac{4}{5}[/tex]
Hence the probability that both balls in the box are red given that all three occasions a red ball is drawn from the box is [tex]\frac{4}{5}[/tex]

Answer:
The first answer is D
the second answer is B
Step-by-step explanation:
The reason why the first answer is D is because in the problem it says at least twice as many seniors is travelling compared to the juniors and D is the only one that shows at least twice than as many juniors and it also it true in the equation 230>2y+x
The reason why the second answer is B is because both of the lines touch at the points (-2,1) which is the same points as B
