Answer:
6 pieces
Step-by-step explanation:
The equation is
4x + 10 = 34
If she had 34 pieces, and kept 10, you can subtract the 10 because she divided the rest of the remaining candy after taking 10.
You now have 24 pieces left to divide, which she does between 4 kids, so you divide it by 4.
Answer:
The mean is usual
Step-by-step explanation:
We have that the mean (m) is equal to 21, the standard deviation (sd) = 1.31 and the sample size (n) = 64
They ask us for P (x <20.5)
For this, the first thing is to calculate z, which is given by the following equation:
z = (x - m) / (sd / (n ^ 1/2))
We have all these values, replacing we have:
z = (20.5 - 21) / (1.31 / (64 ^ 1/2))
z = -3.05
With the normal distribution table (attached), we have that at that value, the probability is:
P (z <-3.05) = 0.0002
The mean is usual because P (x> 20.5) = 1 - P (x <20.5) = 1 - 0.0002 = 0.9998 is a fairly high probability.
Answer:
1 2/6
Step-by-step explanation:
multiply 1 1/2 by 3 to get 3 3/6 then subtract thay from 4 5/6
The answer is 24 + 0.057
