Standard Deviation: 3.5637059362411 Mean:(Average) 9.8 Mad:(Mean Absolute Deviation) 2.4 So the answer is 2.4
Answer:
/A = 30°
/B = 150°
Step-by-step explanation:
Given that the lines are parellel.
Then /A+/B = 180° ( Consecutive interior angles)
Putting given values of angles
6x-18+ 14x+38 = 180
20x + 20 =180
20x = 160
x = 8
/A = 6x-18 = 6×8-18 = 30°
/B = 14x+38 = 14 × 8 +38 = 150°
Answer:
Initially, Anglea has $6*w in total.
Then she buys N books, at $17 each, then the total cost of the books is: N*$17
After that, she had left $w.
a) This means that:
$6*w - N*$17 = $w
Now we can isolate the variable N in one side of the equation:
N*$17 = $6*w - $w = $5*w
N = ($5/$17)*w
N = (5/17)*w
That is the equation that tells the number of books Angela bought in terms of w.
b) Now we just need to replace the w by 34 in the above equation:
N = (5/17)*34 = 10
If w = 34, Angela bought 10 books.
Answer:
13 degrees
Step-by-step explanation:
Let x be the degree measure of the angle's complement
Then we have the other angle is x + 64
Because the 2 angles complement each other so the sum of the 2 angles is 90
So we have the equation: 2x + 64 = 90
<=> 2x = 26
<=> x = 13
7*5*4 is the volume of the package, =140
140/0.5=280.
