The question is worded weirdly, but the mean (average) is 3.3. The median is 4. The median would probably represent this better.
Step-by-step explanation:
The median is found by adding all of the numbers in the data set and then dividing by how many numbers there are.
The median is the middle number, which you find by alternately crossing out the biggest and smallest numbers.

The table shows the change in the water level (in centimeters) of a reservoir for three months. Find the total change in the water level for the three-month period. Write your answer as a fraction or mixed number in simplest form.
The total change in the water level for the three-month period is (BLANK) centimeters.
Answer:
The total change in the water level is [tex]-\frac{33}{28}[/tex]
Step-by-step explanation:
In order to get the total change in something is to add all the numbers together. So, over that three month period, you add -1 3/4-1/28-15/28. SInce you are adding fractions, it helps to have all the denominators the same. Change -1 3/4 into -49/28. (all I did was turn the fraction into an improper fraction then did [tex]\frac{7*7}{7*4}=\frac{49}{28}[/tex] )
Now that we have all the same denominators, just add them/combine them.
[tex]-\frac{49}{28} -\frac{1}{28} -\frac{15}{28}[/tex] = [tex]-\frac{33}{28}[/tex]

Original Price:
Decrease by 85%
Final Price $12.99
Solve for the original price.
Answer:
$86.60
Step-by-step explanation:
Method 1: 12.99 ÷ 15 × 100 = 86.6
Method 2: 12.99 ÷ 15% = 86.6
Using (15 × 100) or 15% because 100% - 85% = 15%

Answer:
option B
Step-by-step explanation:
we first subtract 4 by both sides to get:
3x < -15
now we just divide by 3 on both sides to get
x < -5
the answer is B
Answer:
see below
Step-by-step explanation:
3x+4 less than or equal to -11
Subtract 4 to get 3x isolated
3x < -15
Because x still has something attached to it, you divide by 3
x is less than or equal to -5

Help please!!!! finding the mean/mean absolute value(MAD)
PLease and thank you!!!!
94,86,95,99,88,90
A. mean is 92
B. mean absolute deviation is 4
C. values differ from the mean by an average of 4
A.
94+86+95+99+88+90=552
552 divided by 6 = 92
mean = 92
C.
94-92=2
92-86=6
95-92=3
99-92=7
92-88=4
92-90=2
2+6+3+7+4+2=24
24 divided by 6 = 4
Simplify the expression. Write your answer using decimals.
Answer:
2.4h+2.2
Step-by-step explanation:
4.5h-7.7+9.9-2.1h
To solve this problem, we need to combine like terms.
Because 2.1h is negative, we can subtract it from 4.5h and get 2.4h.
2.4h-7.7+9.9.
We can do the same thing with -7.7 and 9.9. 9.9-7.7=2.2. We have to stop there because constants, numbers without variables, can't be added or subtracted to coefficients, numbers with variables.
Therefore, the simplified equation is 2.4h+2.2.

Answer:
[tex]\boxed{\sf{24\ units\ ^3}}[/tex]Step-by-step explanation:
In order to solve this, you must use the volume of the cube.
[tex]\underline{\textbf{VOLUME OF THE CUBE FORMULA:}}[/tex]
[tex]\Longrightarrow: \sf{V=L*W*H}[/tex]
L: (length) = 3W: (width) = 2H: (height) = 4Multiply.
Use the order of operations.
PEMDAS stands for:
ParenthesesExponentsMultiplyDivideAddSubtract[tex]\Longrightarrow: \sf{3*2*4}[/tex]
First, do multiply.
[tex]\Rightarrow: \sf{3*2=6}\\\\\\\Rightarrow: \sf{6*4=\boxed{\sf{24}}[/tex]
Therefore, the volume of the cube is 24 units³, which is our answer.I hope this helps. Let me know if you have any questions.

Answer: 4/50 equals 2/25
Step-by-step explanation:4/50 and 2/25 equal.08. To get it I did 2×2=4 and 25×2=50 to get 4/50 which equals 2/25 or .08
Answer:
.08 or 8/100
Step-by-step explanation:
First I'd change the fraction to an equivalent fraction with 100 as the denominator since we want the number in hundredths.
If you multiply 25 by 4 you get 100, so that would be the denominator.
Since you multiplied the denominator by 4 you'd also have to multiply the numerator, 2. 2 times 4 is 8.
Now your fraction is 8/100, and if you change this into decimal form, you get .08

599 cm2
217 cm2
307 cm2
689 cm2
Answer:
11. 3,396
Step-by-step explanation:
Given:
Circumference of Mars = 10,664 km
Determine the diameter of Mars.
D = 2r
C=2πr
Solution:
Since we do not have the value of r, we will solve for r in terms of C.
C=2πr
10,644 = 2πr
r = 10644/ 2π
r = 1694.04 km
Now that we know the value of r, we can solve for d.
D = 2r
D = 2( 1694.04km)
D = 3,388.09 km
The nearest value is 3,396 km on the choices, but the answer rounded to the nearest km is 3,388 km
Which term best describes the graph of y = x – 1?
1)increasing
2)decreasing
3)constant
4)positive
Answer:
mark brainliest please!!! <33
Step-by-step explanation:
Since the slope is a positive slope, hence the term that best describes the graph of y = x – 1 is increasing
The standard equation of a line in slope-intercept form is expressed as:
y = mx + b
where:
m is the slope of the lineb is the y-intercept of the lineThe nature of the graph is determined by the slope value.
If the slope is positive, the graph is increasing while if the slope is negative, the graph is decreasing.
Given the function y = x - 1, compared with the general equation;
mx = 1x
m = 1
Since the slope is a positive slope, hence the term that best describes the graph of y = x – 1 is increasing

Solve for x:
3x + 2 = 7x - 6
Answer:
[tex]\sf D.\;\;x=2[/tex]
Step-by-step explanation:
[tex]\sf 3x + 2 = 7x - 6[/tex]
Subtract 2 from both sides:-
[tex]\sf 3x+2-2=7x-6-2[/tex]
Simplify:-
[tex]\sf 3x=7x-8[/tex]
Subtract 7x from both sides:-
[tex]\sf 3x-7x=7x-8-7x[/tex]
Simplify:-
[tex]\sf -4x=-8[/tex]
Divide both sides by -4:-
[tex]\sf \dfrac{-4x}{-4}=\dfrac{-8}{-4}[/tex]
Simplify:-
[tex]\sf x=2[/tex]
