Answer:
Answer is 5
Step-by-step explanation:
Okay hun so let me tell u what's up here
They give us this equation and ask for the 'roots'
(x+5)^3(x-9)(x+1)
Now lemme tell you the roots of this one
-5, 9, -1
you get this from making each of them 0
The answer to this would be "3" because there are 3 roots, buT wait theRe'S mOre
(x+5) goes 3 times
So thy must recount it
-5, -5, -5, 9, -1 <-- These are the roots
that's 5 roots in total
....also I did this on edgen, got it right with 5
Answer:
By the Central Limit Theorem, it is approximately normal with mean 0.29 and standard deviation 0.0596
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean and standard deviation
According to the U.S. Census Bureau, 29% of Americans age 25 years or older have already earned a bachelor's or more advanced degree.
This means that
You decide to randomly select 58 adults over the age of 25 to ask if they have earned at least a bachelor's degree.
This means that
Describe the sampling distribution of the proportion of respondents who have earned at least a bachelor's degree.
By the Central Limit Theorem, it is approximately normal with mean and the standard deviation is
Answer:
25% of 1000 is 250
Step-by-step explanation:
(<u>25 ÷ 100</u>) × 1000
Divide the numbers
<u>0.25</u> × 1000
<u>0.25 × 1000</u>
Multiply the numbers
<u>250</u>
250
B is definitely between those decimals
