Nadia's grades on four quizzes were 95, 75, 85, and 95. Find the mean, median, and mode for Nadia's grades.
Answer:
mean: 87.5
median: 80
mode: 95
What is mean? : the sum of a collection of numbers divided by the number of numbers in the collection so for this is:
95+75+85+95= 350 divided by 4 because there's 4 numbers = 87.5 which is the mean
What is median?: The median is the value separating the higher half of a data sample so for this think of crossing each number at the opposite sides: 95 and 95 cancel now your left with 75 an 85 add them up and divide by 2 because there's 2 numbers **for median you are either left with 1 number or 2 if the case is 2 you ADD first then divide by 2 ALWAYS**: 75+85= 160/2= 80 for median
What is mode?: The mode is the value that appears most often in a set of data. So as we know 95 repeats the most

Step-by-step explanation:
Scott's gas tank is 1/3 full. After he buys 12 gallons of gas, it is 7/9 full. How many gallons can Scott's tank hold?
Answer: We start with the variable "x". Let's call "x" Dan's full tank.
So we know that right now he has 1/3x or 1/3 of a full tank.
After adding 12 gallons, at the end, he has 7/9x, or 7/9 of a full tank
So we start with
(1/3)x + 12 = 7/9x
Let's subtract 1/3x from both sides
12 = 7/9x - 1/3x
Remember, we need to use common denominators to subtract, so 1/3 becomes 3/9
12 = 7/9x - 3/9x
Now we simplify to get
12 = 4/9x
Multiply the reciprocal of 4/9 to both sides which is 9/4
12 * 9/4 = x
Answer is 27 gallons.

Answer:
1.) The height of the cone is 10 and the volume is 2355
2a.) Height 5= Volume 1177.5.
2b.) Height 30= Volume 7065
3.) (I'm not exactly sure because I haven't done this in a while.)
I guess 30= diameter
4.) 1 unit of height = 235.5 units of volume
Sorry if i messed up 3 or 4. I haven't calculated this stuff in a while.
Step-by-step explanation:
1.) It says the height of the cone on the horizontal ray and volume of the cone of the vertical ray.
2.) Divide 10 by 2 to get 5 height - Divide 2355 by 2= 1177.5
2b.) Multiply 10 by 3= 30 height - Multiply 2355 by 3= 7065
3.) r= √3× (V ÷ h) subtitute: r= √3× (2355 ÷ 3.14× 10)
simplify: r= 14.99... Diameter = 2 radius so about 30
4.) Divide 2355 by 10 to get the unit ratio. 1 unit of height is 235.5 volume.
Use either the commutative property or combine like terms to create an equivalent expression
from the expression 9(2j + 5j).
Answer:
9(7j)/63j
Step-by-step explanation:
9(2j+5j)
= 9(7j)
= 63j
A 12-sided die is numbered 1-12. What is P(rolling a number less than 7)
Answer:
1/2
Step-by-step explanation:
This 12-sided die has 6 surfaces (sides) numbered less than 7. Thus,
P(rolling a number less than 7) = 6/12 = 1/2

Consider the data below.
2, 2, 2, 3, 5, 6, 8, 30
The mean decreases by ? when the outlier is removed.
Answer:
It is decreased by 3.25
Step-by-step explanation:
When you add all 8 numbers you'll get 58 then you divide them by 8 you will get 7.25 which is the mean. To find out what is the decrease we need to take out the 30 and add all the other numbers and we get 28. After that you divide 28 by 7 and you get 4. Subtract 4 from 7.25 and you get 3.25.
2+2+2+3+5+6+8+30=58
58/8=7.25
2+2+2+3+5+6+8=28
28/7 = 4
7.25-4=3.25

A. does 24 ft = 2in ?
No, your answer should be,
[tex]\Huge\boxed{288}[/tex]
To convert feet into inches, you multiply the length value by 12. Your mistake is you got it mixed-up. 24ft doesn't equal 2in, but 24in equals 2ft, because instead of multiplying 12, you divide by 12.
24ft → 288in
24 × 12 = 288
24in → 2ft
24 ÷ 12 = 2
Hence, 24ft doesn't equal 2in.

How many pounds of cashew nuts worth 75 cents a pound must be mixed with 10 pounds of pecans worth $1.50 a pound to make a mixture worth $1.00 a pound? Which of the equations could be used to solve for p, the pounds of cashew nuts?
75 p + 150(10) = 100( p + 10)
75 p + 150 = 100( p + 10)
75( p + 10) + 150(10) = 100( p + 10)
Answer:
75p+150(10)=100(p+10)

leven purple marbles, seven orange marbles and two pink marbles are in a bag. What is the probability of selecting a purple marble, not replacing it, and then selecting an orange marble?
Question 4 options:
19%
20%
21%
22%
Answer:
The probability of picking a purple marble, and then, not replacing picking an orange marble is approximately 20%
Step-by-step explanation:
First we know that there are 20 marbles in the bag, so the probability of picking a purple marble is 11/20. If we take a purple marble out, there will only be 19 marbles remaining in the bag. So the probability of picking an orange marble would be 7/19. Now, all we need to do is multiply the 2 fractions, and we will get 77/380 which equals to which is approximately 20% .
