Answer:
20
21.75
27.85
29.5
Step-by-step explanation:
Arranging the values in ascending order we get
16 21 24 24 27 28 30 35
n = Number of values = 8
Rank is given by
[tex]\dfrac{\text{Percentile}}{100}\times (n+1)[/tex]
[tex]=\dfrac{20}{100}(8+1)=1.8[/tex]
Taking the fraction of the rank i.e., 0.8 and work out the weighted mean
[tex]0.8\times (21-16)+16=20[/tex]
The 20th percentile is 20
[tex]\dfrac{25}{100}(8+1)=2.25[/tex]
[tex]0.25(24-21)+21=21.75[/tex]
The 25th percentile is 21.75
[tex]\dfrac{65}{100}(8+1)=5.85[/tex]
[tex]0.85(28-27)+27=27.85[/tex]
The 65th percentile is 27.85
[tex]\dfrac{75}{100}(8+1)=6.75[/tex]
[tex]0.75(30-28)+28=29.5[/tex]
The 75th percentile is 29.5
Suppose the average wait time for a sandwich at a local deli is 55 min with a standard deviation of 33 min. Is it unusual to wait over 1212 minutes to get a sandwich?
Answer:
The wait time is unusual because the probability value obtained is less than 2 standard deviation above the mean
Step-by-step explanation:
From the question we are told that
The average wait time is [tex]\mu = 55 \ min[/tex]
The standard deviation is [tex]\sigma = 33 \ min[/tex]
Generally the probability of waiting over 1212 minutes is
[tex]P(X > 1212) = P(\frac{X - \mu}{ \sigma } > \frac{ 1212 - 55}{ 33} )[/tex]
[tex]P(X > 1212) = P(\frac{X - \mu}{ \sigma } > \frac{ 1212 - 55}{ 33} )[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
So
[tex]P(X > 1212) = P(Z > 35 )[/tex]
From z table the probability of (Z > 35 ) is
[tex]P(Z > 35 ) = 0[/tex]
Hence
[tex]P(X > 1212) = 0[/tex]
The time is unusual because the probability value obtained is less than 2 standard deviation above the mean

Factor this polynomial completely.
x2 - 6x + 9
O A. (x+3)(x + 3)
OB. (x+3)(x-3)
O C. Does not factor
O D. (x - 3)(x-3)
==========================================================
Explanation:
The last term is 9 and the middle coefficient is -6.
We need to find two numbers that multiply to the last term, and also add to the middle coefficient.
Through trial and error, you should find the two numbers -3 and -3
-3 plus -3 = -6
-3 times -3 = 9
Those two values directly lead to the factorization (x-3)(x-3)
We can FOIL out (x-3)(x-3) to get x^2-6x+9 to help confirm the answer. Distribution works as well. The box method is a visual way to do it also.

A chef uses 1/2 cup of tomatoes for every 1/8 cup of onions to make salsa. How
many cups of onions will the chef need for 1 cup of tomatoes?
Answer:
he or she will need to use 2/8 cups of onions for 1 cup of tomatoes to be used
Step-by-step explanation:
The chef need 1/4 cups of onion for 1 cup of tomato.
What is fraction?Fractions are used to represent smaller pieces (or parts) of a whole.
Given that, a chef uses 1/2 cup of tomatoes for every 1/8 cup of onions to make salsa
So, for 1/2 → 1/8
Multiplying each side by 2 to get 1 cup of tomato,
1 → 2/8 = 1/4
Hence, the chef need 1/4 cups of onion for 1 cup of tomato.

State the x-values where the limit does not exist.
9514 1404 393
Answer:
x = -2x = 2Step-by-step explanation:
There are vertical discontinuities in the function at x=-2, x=2, and x=4. When looking at limits, we find the function values to be different either side of those discontinuities at x = -2 and at x = 2. Thus, limits do not exist at those points (x = {-2, 2}).
At x=4, the discontinuity is in the function definition, not in the values left or right of that point. Hence the limit does exist at x=4, but the function is not continuous there.
What is the slope
A. slope=1/3
B. slope= -3
C. slope = 3
Answer:
3
Step-by-step explanation:
slope = rise/run
Start at an easy to read point, such as (0, -2).
Go up 3 and right 1.
That is a rise of 3 and a run of 1.
slope = rise/run = 3/1 = 3
Answer: 3
Answer:
3
Step-by-step explanation:
Count how many points it goes up and then over to cross a square through the corner. In this case it goes up 3 over one. That simplifies to be just 3. Hope that made sense.

Joe has 5 shirts, 3 pairs of pants and 4 pairs of shoes. He needs to make an outfit containing one of each item. How many different outfits are possible?
Answer:
60 outfits
Step-by-step explanation:
5 shirts x 3 pants x 4 shoes = 60 outfits (containing 1 shirt, 1 pant, 1 shoe)
This is pretty difficult to explain, but this is basically how you do it when you want to see how many combinations of something there are for multiple different things. Basically, for each of the 5 shirts, there are 3 different pants, and for each of the pants there are 4 shoes. So each pant has 4 shoes, then multiply that by 3 for the 3 pants for each shirt. After that, multiply by 5 for each shirt in the outfits.
What is the equation of a line that is passing through the point (2, 11)
and is parallel to the line y = 4x – 5?
Answer:
y=4x+3
Step-by-step explanation:
since its parallel they have the same slope
y=mx+b
(11)=(4)(2)+b
11=8+b
then subtract 8 on both sides
11=8+b
-8=-8+b
3=b
then y=4x+3
