Answer:
Step-by-step explanation:
Given that in a study of a weight loss program, 4 subjects lost an average of 48 lbs.
It is found that there is about a 32% chance of getting such results with a diet that has no effect.
The results do not appear to have statistical significance. The reasons are
1) Sample size of 4 is very small not even meeting the bare minimum
2) Sample of 4 cannot be taken to represent the population
3) Whether bias was there in the selection of sample is not known.
4) Std deviation is not considered which is very important while concluding results.
Answer:
σX = 3161
Step-by-step explanation:
The standard deviation is the square root of the multiplication of each probability multiplied by the squared difference between the values and the mean.
In this question:

Rounding to the nearest dollar, σX = 3161
Answer: B
Step-by-step explanation:
The only labeled angle is 111
We can conclude that angle 3 is also 111
1 and 2 are both less than 90
Therefore, 1 is 69, 2 is 69, and 3 is 111
Answer:
NO, this is not prime factorization.
The correct prime factorization is = 
Step-by-step explanation:
Prime factorization means, writing the given number as product of prime numbers.
In the above case, in the prime factorization,<em> the number 8 is present which is not a prime number.</em>
8 can be further represented as product of prime numbers as,

Now the prime factorization reduces to,
= 
= 
Answer:
Step-by-step explanation:
Part 1: x represents her bank account
Part2: 135-x=y
Part 3: I'm not sure how long she's worked there, but it would look like: 7.85x=y. X representing number of hours
