Answer:
37) -1/3
38) 8/5
39) 0
40) -2/3
Step-by-step explanation:
Answer:
almost -.4
Step-by-step explanation:
The way I would answer these when I was in school, just divide -3/7.
that gives you -.428 so it is pretty close to .-4, but not exactly on it.
B. the difference between 6 and 4 is doubled ,why? becuz 6-4 is 2 and 2 is doubled by 2 and u get 4 basically 2 times 2 is 4 ..hope this helps!
Answer:
By the Central Limit Theorem, the distribution of the sample means is approximately normal with mean 41 and standard deviation 2.92, in thousands of dollars.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes 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.
Mean of 41, standard deviation of 28:
This means that 
Sample of 92:
This means that 
Distribution of the sample means:
By the Central Limit Theorem, the distribution of the sample means is approximately normal with mean 41 and standard deviation 2.92, in thousands of dollars.
The representation of √14 on number line is shown below.
<h3>What is Number line?</h3>
A visual representation of numbers on a straight line is known as a number line. A number line's numerals are arranged in a sequential manner at equal intervals along its length. It is typically represented horizontally and can extend indefinitely in any direction.
On a number line, the numbers rise as you move from left to right and fall as you move backwards from right to left.
Given:
For drawing number line of root number we will use spiral method.
So, Using Pythagoras theorem
H² = P² + B²
H² = (√13)² + 1²
H² = 14
H = √14
So, we will take Perpendicular 1 unit and base of √13 unit.
