What is the mean absolute deviation?
Answer:
the MAD to this set is 6.75
Step-by-step explanation:
The process is pretty long on how to find the MAD but here it goes.First you find the mean of the set( 70 )then you find the distances between all the numbers and the mean( 68 is 2 values away from being 70 so that would be 2) than you add all the distances together than divide that number by the amount of values are in the set.
hope that makes sense have a good day

if you spin the spinner below twice, what is P(vowel, then Q)?
Answer:
1/12
Step-by-step equation
Since your spinning a spinner twice which has a chance of landing on any number with a 1/6 chance spinning a number than q would give you a 1/12 chance. Another equation would be 1/6 * 2

Step-by-step explanation
Answer:
199.51$
Step-by-step explanation:
10 x 12 = 120$
25 x 5 = 125$
5 x 8 = 40¢
1 x 11 = 11¢
30 + 50 = 80$
120$ + 125$ + 40¢ + 11¢ + 80$ = 325.51$
325.51$ - 44$ = 281.51$ - 25$ = 256.51$ - 12$ = 244.51$ - 15$ = 229.51$ - 30$ = 199.51$
Help I need step by step answer To the ones circled ASAP!!!!
Answer:
4. Multiply both sides by -2 => x - 7 = -36, Add 7 to both sides -> x = -29
5. Add 12 to both sides => 28 = 1/4x, then multiply both sides by 4 => 112
x = 112
7. Multiply both sides by 3 => 5x - 2 = 63, add 2 to both sides => 5x = 65,
Divide both sides by 5 -> x = 13
10. Multiply both sides by 6 => 132 = 3x - 6, Add 6 to both sides => 138 = 3x,
Divide both sides by 3 => x = 46

What is the volume of the cone to the nearest cubic meter? (Use π = 3.14.) Refer to your STAAR 8th Grade Math Reference Sheet for the appropriate formula.
Height: 5 m
Radius: 4 m
Answer:
V≈83.78
Step-by-step explanation:
The formula to find the volume of a cone is V=πr(squared) h/3
Steps
V= π (4)^2 5/3
V= π (16) 1.66666666667
V = 50.2654824574 * 1.66666666667
v= 83.7758040958
Round
V = 83.78
Answer:
The volume of cone is 83.73m³.
Step-by-step explanation:
Given Parameters:Height of the cone = 5m Radius of the cone = 4mTo find:Volume of the coneSolution:To find the volume of the cone we use Formula:
[tex] \sf V = \frac{1}{3} \pi {r}^{2} h \\ \\ \implies \: \frac{1}{3} \times 3.14 \times {4}^{2} \times 5 \\ \\ \implies \frac{1}{3} \times 15.70\times 16 \\ \\ \implies \: \frac{1}{ \cancel3} \times \cancel{251.20} \\ \\ \implies \sf \pink{83.73 {m}^{3} }[/tex]
Hence, the volume of cone is 83.73m³.

Mode means the number that repeats the most. Out of all the numbers, 88 repeats itself three times in the set of data while all the numbers are there once or twice.
Today is Maria's birthday. She is 7 years old. How old is Maria in months?
Answer:
84 months
Step-by-step explanation:
Maria is 7 years old, there are 12 months in a year, multiply 12 by 7.
12 * 7 = 84
Maria is 84 months old
Answer:
Maria is 84 months old.
Multiply the years(y) by every 12 months that pass(m).
[tex]y * m = 84[/tex]
note that y is 7, and m is 12, because we count every 12 months that pass for 7 years.

Answer:
(b) y = 4x +15; y = 10x -2
Step-by-step explanation:
It is often sufficient to check for reasonableness in the offered answers. That is the case here.
__
The offered answer choices differ in the combinations of slope. The offered slopes (x-coefficients) are 4 or 1/4, 10 or 1/10, so it is sufficient to determine if the slope is greater than 1 in each case.
The slope is the ratio of the change in y to the change in x. It will be greater than 1 if y changes by a larger number than x does.
1st Tablex-values in this table change by 4-2 = 2. y-values change by 31 -23 = 8, which is more than 2. The slope is greater than 1 for the first equation. (It is 8/2 = 4.)
2nd TableThe first two x-values in this table differ by 0-(-1) = 1. The first two y-values differ by -2-(-12) = 10, which is more than 1. The slope is also greater than 1 for the second equation. (It is 10/1 = 10.)
Answer choicesThe x-coefficients in the answer choices are ...
a) 1/14, 1/10 . . . incorrect
b) 4, 10 . . . . correct
c) 1/4, 10 . . . . partly correct
d) 4, 1/10 . . . . partly correct
