Answer:
Its actually one solution it is solvable and only has one solution
Step-by-step explanation:
Answer:
7.4
Step-by-step explanation:
just divide it by 3.2
Answer: The answer is G
Step-by-step explanation:
If you don't see the stars, then the sky is not clear. This statement is equivalent to saying "If the sky is not clear, then you don't see the stars", because if you rearrange both statements you will find out that they are equivalent to each other.
Mark out all the words in each statement, you will discover that at the end you will have no word left on both side, its just as good as saying 1 - 1 = 0.
Using the normal distribution, there is a 0.2148 = 21.48% probability that the sum of the 40 values is less than 7,100.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
- By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation
.
For this problem, these parameters are given as follows:

A sum of 7100 is equivalent to a sample mean of 7100/40 = 177.5, which means that the probability is the <u>p-value of Z when X = 177.5</u>, hence:

By the Central Limit Theorem:


Z = -0.79
Z = -0.79 has a p-value of 0.2148.
There is a 0.2148 = 21.48% probability that the sum of the 40 values is less than 7,100.

Answer:
(DONT INCLUDE THE LETTERS, IT JUST TRIES TO CONFUSE)
So, -1/4 is more than 3 (which you should know) and 3-12 is -9, then it says -9 is more than 12, which is not true. You should show your work as a model explaining what I explained earlier. So you would answer non-equal. Thanks for helping run my brain (lol)
