Answer:
The value is 14
Step-by-step explanation:
six less than (next quotient -6) the quotient of a number and two (n/2), increased by ten (+10) when n = 20.
(<u>n</u>/2)+10-6; <u>n=20</u>
<em>Substitute 20 in for n.</em>
(<u>20/2</u>)+<u>10-6</u>
<em>Divide and subtract.</em>
<u>10+4</u>
<em>Add.</em>
14
Answer:
A reflection over the x axis
Step-by-step explanation:
With the x axis you flip it down or up
With the y you flip it to the left or to the right
Answer:
A
Step-by-step explanation:
because it's subtracting the xaxis by -2 so subtracting it will cause the linear equations to shift left by 2 untis
Answer:
r>7
Step-by-step explanation:
Subtract 2.92.9 from both sides
-1.3-2.9>-0.6r−1.3−2.9>−0.6r
Simplify -1.3-2.9−1.3−2.9 to -4.2−4.2
-4.2>-0.6r−4.2>−0.6r
Divide both sides by -0.6−0.6
\frac{-4.2}{-0.6}<r
−0.6
−4.2
<r
Simplify \frac{-4.2}{-0.6}
−0.6 −4.2 to 77
7<r
Switch sides
r>7
Mean Absolute Deviation is a quantity of measurement that gives you an idea how far, on average, are the data points deviating from the mean. Its equation is
MAD = ∑|x - μ| / N, where
x is a single data point
μ is the mean of the data set
N is the total number of data points
Suppose, a data set consist of the following: 4, 7, 5, 9, 6, 7, 7, 4. Let's solve first for the mean:
μ = (4+7+5+9+6+7+7+4)/8 = 6.125
Then, the MAD is equal to:
MAD = (|4 - 6.125| + |7 - 6.125| +|5 - 6.125| +|9 - 6.125| +|6 - 6.125| +|7 - 6.125| +|7 - 6.125| +|4 - 6.125|) ÷ 8
MAD = 11/8
MAD = 1.375
