The mean absolute deviation of the given data set is 1.2.
How to calculate the mean absolute deviation of a data set?Mean absolute deviation (MAD) is a measure of the average absolute distance between each data value and the mean of a data set. The formula for MAD is:
MAD =∑|x-m| / n
∑ is known as Sigma and means to sum up
| | are vertical bars that mean absolute value
x is each value
m is the mean
n is the total number of data points in your data set
Given: 2, 3, 1, 5, 4
n = 5
m = 2 + 3 + 1 + 5 + 4 = 15/5 = 3
∑|x-m| = |2-3| + |3-3| + |1-3| + |5-3| + |4-3| = 6
MAD =∑|x-m|/n = 6/5 = 1.2
Therefore, the mean absolute deviation of the set data is 1.2

Mr Jones bought a snowboard. The 6% sales tax on the snowboard was $32.50. What was the total cost including the sales tax? (rounded to nearest cent)
Answer: $574
Step-by-step explanation:
First we need to calculate the price of the snowboard before the addition of the tax. This will be represented by x. Therefore,
6% of x = $32.50
0.06 × x = $32.50
0.06x = $32.50
x = $32.50 / 0.06
x = $541.67
Therefore, the total cost including the sales tax will be:
= $541.67 + $32.50
= $574.17
= $574

Write and solve a proportion to answer the question. 36 is 0.9% of what number w? 36/w = .9/100 what is w? w = ?
Answer:
4000
Step-by-step explanation:
To solve :
36 = 0.9% of w ; solve for w
36 = 0.9/100 * w
36 = 0.009w
Divide both sides by 0.009
36/0.009 = 0.009w / 0.009
4000 = w
Hence, the number, w equals 4000

find the surface area of the prism. 3in , 8in ,5in.
Answer:
158 in.
Step-by-step explanation:
Surface area of a prism = Area of all the faces added together
So, Face 1 & 2 = 5 x 80 = 40 x 2 = 80
Face 3 & 4 = 8 x 3 = 24 x 2 = 48
Face 5 & 6 = 5 x 3 = 15 x 2 = 30
Therefore, adding them together makes:
80 + 48 + 30 = 158 in.

From the set {5, 9, 12}, use substitution to determine which value of x makes the equation true. 12(x - 4) = 96
Answer:
12
Step-by-step explanation:
12(5-4)=96
60-48=12 means it's not five
12(9-4)=96
108-48=60 means it's not 9
12(12-4)=60
144-48=96 so answer is 12

Which best proves why the expressions 4 (x + 3) + 2 x and 6 (x + 2) must be equivalent expressions? When x = 3, both expressions have a value of 30. When x = 5, both expressions have a value of 42.
Answer:
The answer is choice first which is "When x = 3, both expressions have a value of 30".
Step-by-step explanation:
Given:
First expression: [tex]4(x+3)+2x[/tex]
Second expression: [tex]6(x+2)[/tex]
Through the question when we substitute x=3 into its first equation so we get:
[tex]\to 4(3+3)+2(3) \\\\ \to 4\times (6)+6\\\\ \to 24+6\\\\ \to 30[/tex]
The value will be substituted by x=3 into its second expression:
[tex]\to 6(3+2)\\\\ \to 6(5)\\\\ \to 30[/tex]
So, it will prove that both the two expressions are equivalent.

Please help me with this !
Answer:
a. 4 (or maybe like 3.5)
b. 6
Step-by-step explanation:
a. Going from x = 0 to x = 8, it is obvious that y goes down 4 or 4.5 units during this stretch. This gives an approximate slope of -3/8. With this in mind, it can be easily calculated that going the remaining distance from x = 8 to x = 10, the value of y will be approximately 4 or so.
b. A dot literally is right next to (6, 6).
Чx-2(x+4)=22
How do I do this
Answer:
x = 7
Step-by-step explanation:
4x - 2(x + 4) = 22

Combine like terms:
2x - 8 = 22
Simplify and solve:
2x = 14
x = 7
Answer:
4x-2x-8=22
2x-8=22
2x=30
x=15

Karl is comparing the interest rates for accounts at two different banks. He will deposit $600 into an account and will not make any additional deposits or withdrawals. Bank Q offers 1% interest compounded annually. Bank R offers 1.5% simple interest.
Answer: bank R for 1 year
Step-by-step explanation:
Given
Principal deposit is [tex]P=\$600[/tex]
Bank Q offers 1% interest compounded annually
Bank R offers 1.5% simple interest annually
For Bank Q, Compound interest is given by
[tex]\Rightarrow P[1\frac{R}{100}]^t-P[/tex]
for 1 year it is
[tex]\Rightarrow 600[1+\frac{1}{100}]-600=\$6[/tex]
For bank R, simple interest is
[tex]S.I.=\dfrac{P\times R\times T}{100}[/tex]
for 1 year it is
[tex]\Rightarrow S.I.=\dfrac{600\times 1.5\times 1}{100}=\$9[/tex]
Clearly, bank R offers more interest for 1 year
