Answer:
Step-by-step explanation:
C=$200
B=175 frisbees to sell
P=$5
$200-175=$25
25/5=$5
the profit is $5 because you're selling the fribees because you'll be gaining
$5 every sell.
and and you have 175 frisbees to sell so 5x175
$875 you'll gain when you sell them all!!
hope this helps. :D
Step-by-step explanation:
if 900 is increased by 20% then
120/100×900=1080
Decreasing it by 20% then
80/100×1080=864
Answer:
No
Step-by-step explanation:
All whole numbers, positive, negative, and 0 are integers.
In addition to mean and sample size you will need the individual scores.
The formula for standard deviation is:
S^2 = E(X-M)^2/N-1
Here's an example:
Data set: 4,4,3,1
Mean: 3
Sample size: 4
First, put the individual scores one after the other and subtract the mean from it.
4 - 3 = 1
4 - 3 = 1
3 - 3 = 0
1 - 3 = -2
Second, square the answers you got from step 1.
1^2 = 1
1^2 = 1
0^2 = 0
-2^2 = 4
Third, plug the values from step 2 into the formula.
S^2 = (1+1+0+4)/(4-1) = 6/3 = 2
Standard deviation = 2
18=3(x-1)
18=3x-3
18-3=3x
15=3x
15/3=x
x=5
