Answer
Step-by-step explanation:
Answer:
No, this result is not surprising. It is a little bit more than one standard deviation above 20%
Step-by-step explanation:
Proportion of each color in the population (p) = 0.20
Sample size (n) = 20 Skittles
The standard deviation of a sampling distribution is determined by:
The difference between the observed proportion of 0.30, and the mean proportion of 0.20 is 0.10, which is just a little bit more than one standard deviation of 0.089. Therefore, this result is not surprising since it is a little bit more than one standard deviation above 20%.
12x7x3=Volume recipe, the dirt they have to remove is within that volume so just do that formula and bam you got your answer
Answer:
Hey I think it is C. Symmetry but im no all the way sure
Step-by-step explanation:
Answer:
Square=5
Triangle=17
Circle=8
Step-by-step explanation:
s=square, c=circle, t=triangle
What each column tells us:
2t+2c=50
3s+t=32
c+2s+t=35
What each row tells us:
2t+c=42
c+2s=18
t+2s=27
c+s+t=30
Solve for s and t:
We will use 3s+t=32 and t+2s=27 to find s and t.
3s+t=32
t=32-3s
Plug in 32-3s for t and solve for s.
(32-3s)+2s=27
32-s=27
-s=27-32
s=5
Square=5
Plug in 5 for s and solve for t.
t+2(5)=27
t+10=27
t=17
Triangle=17
Use c+s+t=30 to find c:
Plug in 5 for s and 17 for t.
c+5+17=30
c+22=30
c=8
Circle=8
