Answer:
<h2>
66 different ways </h2>
Step-by-step explanation:
This is a combination question. Combination has to do with selection. For example if r objects are to be selected from n pool of oblects, this can be done in nCr number of ways.
nCr = n!/(n-r)r!
According to the question, if a radio show can only play 10 records out of 12 records available, this can be done in 12C10 number of ways.
12C10 = 12!/(12-10)!10!
= 12!/2!10!
= 12*11*10!/2*10!
= 12*11/2
= 6*11
= 66 different ways
Each friend would get 3/4 of a sandwich.
We take the 8 sandwiches and decide them by six. Then we get 0.75. Then we change it to fractions.
0.75. 75
——- x 100 ——- Then we simplify.
1. 100. And get 3/4
Answer:
x=9
Step-by-step explanation:
Add similar elements: -5x+3x=-2x
-2x+15=-3
Subtract 15 from both sides
-2x + 15-15=-3-15
Simplify
-2x=-18
Divide both sides by -2
-21/-2 = -18/-2
Simplify
x=9
Answer: The first option with sss as part of the proof
Step-by-step explanation:
The lengths of the arcs drawn in the constructions are the same, so when the line is drawn, the lengths of the sides will all be the same. SSS is proof of congruence.
CPCTC is an acronym for "corresponding parts of congruent triangles are congruent."
Answer:
c. 20
Step-by-step explanation:
Calculation to determine Which of the following is the resulting MAD value that can be computed from this data
Using this formula
MAD= [ABS( Year 1 actual unit demand - Forecast) + ABS (Year 2 actual unit demand - Forecast) + ABS (Year 3 actual unit demand - Forecast) + ABS (Year 4 actual unit demand - Forecast)]/ Number of years
Let plug in the formula
MAD = [ABS(100 - 120) + ABS (105 - 120) + ABS (135 - 120) + ABS (150 - 120)]/4
MAD =(ABS 20) + (ABS 15) + (ABS 15) + (ABS 30)/4
MAD= 80/4
MAD=20
Therefore the resulting MAD value that can be computed from this data is 20
