Answer:
30
Step-by-step explanation:
Solve for n: 0.22n = 6.6.
- 6.6/0.22 (because for example 3/3 and n/n= 1 so 0.22/0.22 = 1 so we have to divide 6.6 since it is part of the equation and we have to do it on both sides.)
- =30
Answer: 14
Explanation:
We can demote the smallest even number by
n1=2n
So, the next consecutive even integers would be
n2=2(n+1)=2n+2, and
n3=2(n+2)=2n+4
So, the sum is:
n1+n2+n3=(2n)+(2n+2)+(2n+4)
We are told that this sum is 48, thus:
(2n)+(2n+2)+(2n+4)=48
∴6n+6=48
∴6n=42
∴n=7
And with n=7, we have:
n1=14
n2=16
n3=18
Hope this helps!
If LMNO is a parallelogram:
6 x - 5 = 4 x + 17
6 x - 4 x = 17 + 5
2 x = 22
x = 22 : 2
x = 11
and:
5 y + 29 = y + 25
5 y - y = 25 - 29
4 y = -4
y = -4 : 4
y = -1

Step-by-step explanation:
Answer:
Mean 24, standard error 0.8
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , the sample means with size n of at least 30 can be approximated to a normal distribution with mean and standard deviation, also called standard error
In this problem, we have that:
What are the mean and the standard error of the sample mean?
By the Central Limit Theorem, mean 24 and standard error
