Answer:
3
Step-by-step explanation:
Same sides
You didn't supply any rules or constraints so.... 1 in., 1 in., and 1 in.
You can use the Pythagorean Theorem to check if the side lengths are appropriate.
–this is true.
Step-by-step explanation:
ATQ,
Let d be the number of kilograms of dark chocolate she buys and m be the number of kilograms of milk chocolate she buys.
She needs to buy 120 kg of chocolate in total for her next order, and her recipe calls for twice the amount of dark chocolate as milk chocolate.
So,
m = 2d .....(1)
m + d = 120 ...(2)
We can also solve the above equations,
Put m = 2d in equation (2)
2d + d = 120
3d=120
d = 40
Put d = 40 in equation (1)
m = 2(40)
m = 80
Hence, she will need 40 kg of dark chocolate and 80 kg of milk chocolate.
Answer:
e) The mean of the sampling distribution of sample mean is always the same as that of X, the distribution from which the sample is taken.
Step-by-step explanation:
The central limit theorem states that
"Given a population with a finite mean μ and a finite non-zero variance σ2, the sampling distribution of the mean approaches a normal distribution with a mean of μ and a variance of σ2/N as N, the sample size, increases."
This means that as the sample size increases, the sample mean of the sampling distribution of means approaches the population mean. This does not state that the sample mean will always be the same as the population mean.
Answer:
B. 11 2/3
Step-by-step explanation:
c = 5 5/6*2
Change the mixed number to an improper fraction
5 5/6 = (6*5+5)/6 = (30+5)/6 = 35/6
c = 35/6 *2
c = 35/6 *2/1
= 70/6
Now we change it back to a mixed number
6 goes into 70 11 times
11*6 = 66 with 4 left over
11 4/6
We can simplify 4/6 by dividing the top and bottom by 2
11 2/3
