Answer:$192.50
Step-by-step explanation:
$11 ×17.5=182.50
Simplify by combining like terms to
-n+4=8n-5
subtract 8n from both sides
-n+4-8n=8n-5-8n
-9n+4=-5
subtract 4 from both sides
-9n+4-4=-5-4
-9n=-9
Divide both sides by -9
-9n/-9=-9/-9
n=1
hope this helps!
Answer:
(A)12-19
Step-by-step explanation:
To construct a frequency distribution, we follow the steps below.
1. Find the largest and smallest values.
91 and 12 respectively
Compute the Range = Maximum - Minimum=91-12=79
2. Determine the number of classes desired.
In this case, we desire 10 classes
3. Next, we find the class width by dividing the range by the number of classes and rounding up.
79÷10 = 7.9
Rounded Up, Class Width=8
4. Pick a suitable starting point less than or equal to the minimum value.
Since our minimum value is 12, we pick a class starting with 12 and give a class width of 8.
Therefore the upper and lower limits of the first class is given as:
12-19.
Answer:
1) 0.5
2)-2
3)-23
Step-by-step explanation:
1) -3×1=-3
-3+2.5= 0.5
2) -3×1.5=-4.5
-4.5+2.5= -2
3) -3×8.5=-25.5
-25.5+2.5=-23
