Find the mean median and mode 15,3, 11, 15,1,14,7,2,1,1,2

Answers

Answer 1

Answer:

Answer: Median = 3, Mean = 6.45, Mode = 1.

Step-by-step explanation:

Since we have given that

15,3, 11, 15,1,14,7,2,1,1,2

As we know the formula for "Mean" :

$Mean=(15+3+11+15+1+14+7+2+1+1+2)/(11)\n\nMean=6.45$

Mean = 6.45

Similarly, we know the formula for "Median":

First we write it in ascending order:

1,1,1,2,2,3,7,11,14,15,15

$Me=((n+1)/(2))^(th)\nMe=(11+1)/(2)^{th]\nMe=(12)/(2)^{th]\nMe=6^(th)\nMe=3$

Median = 3

Mode is the number which has occurred mostly, has the highest frequency.

Mode = 1

Hence, Median = 3, Mean = 6.45, Mode = 1.

Answer 2

Answer: well, the mode is what's most often and that's:
1
the mean is:
6.5454545454545
the median is:
3

With Gillian taking oranges out of the sorter, it takes 25 minutes for Perry to fill the sorter.Which of the following can be used to determine the amount of time it takes for Gillian to empty the sorter if Perry does not add oranges? A) 1 over 10 minus 1 over x equals 1 over 25 B) 1 over 10 minus 1 over 25 equals 1 over x C) 1 over 25 minus 1 over x equals 1 over 10 D) 1 over 10 minus 1 over x equals x over 25

Dwayne is selling hamburgers and cheeseburgers. He has 100 burger buns. Each hamburger sells for $3, and each cheeseburger sells for $3.50. Which system of inequalities represents the number of hamburgers, h, and the number of cheeseburgers, c, he must sell to have sales of at least $80? h + c ≤ 80 3h + 3.5c ≤ 100 h + c ≤ 80 3h + 3.5c ≥ 100 h + c ≤ 100 3h + 3.5c ≤ 80 h + c ≤ 100 3h + 3.5c ≥ 80

Answers

Given:
hamburger = h ; sells for 3
cheeseburger = c ; sells for 3.50
100 burger buns

h + c = 100

3h + 3.5c > 80 last option.

Step-by-step explanation:

Talia wants to write the equation of the graphed line in point-slope form. These are the steps she plans to use: Step 1: Choose a point on the line, such as (2, 5).
Step 2: Choose another point on the line, such as (1, 3).
Step 3: Count units to determine the slope ratio. The line runs 1 unit to the right and rises 2 units up, so the slope is.
Step 4: Substitute those values into the point-slope form. y – y1 = m(x – x1) y – 3 = (x – 1) Which of Talia’s steps is incorrect? Step 1 is incorrect because it uses a point that is not on the line. Step 2 is incorrect because it uses a point that is not on the line. Step 3 is incorrect because it shows an incorrect ratio of the slope.
Step 4 is incorrect because it shows an incorrect substitution of (1, 3) into the point-slope form

Answers

From the steps Talia chooses to find the equation of the line, we shall evaluate the incorrect step as follows:
Step 1:
Choose a point in the line such as (2,5)
Step 2:
Choose another point on the line, such as (1, 3)
step 3:
Count units to determine the slope ratio. The line runs 1 unit to the right and rises 2 units up, so the slope is.
(5-3)/(2-1)=2/2=1
step 4:
Substitute those values into the point-slope form
y-y1=m(x-x1)
y-3=2(x-1)
y=2x+1
Thus the answer is:
Step 4 is incorrect because it shows an incorrect substitution of (1, 3) into the point-slope form

just took the test the right answer is step 3 is incorrect

60 is what percent of 72

Answers

If you would like to solve 60 is what percent of 72, you can calculate this using the following steps:

60 is what percent of 72
60 = x% of 72
60 = x% * 72
60 = x/100 * 72
60/72 = x/100
x = 60/72 * 100
x = 83.33%

The correct result would be 83.33%.

60 is 83% of 72.

60 divided by 12 is 5, and 72 divided by 12 is six.
5/6 equals 0.83
0.83 x 100 is 83, or 83%.

For the first 3 years of a horse's life, the weight, w (in kilograms), of the horse approximately fits the formula w(t)=30+170t, where t is the age of the horse in years. Which of the following is the most accurate interpretation of the slope of the line represented by this formula? A. The slope is 170. This means that the horse gains an average of 170 kilograms per year for the first 3 years of its life.
B. The slope is 30. This means that the horse gains a total of 30 kilograms in the first 3 years of its life.
C. The slope is 30. This means the horse gains on average 30 kilograms per use for the first 3years of its life.
D. The slope is 170. This means that the horse gains a total of 170 kilograms in the first 3 years of its life.
