Answer:
<h2>E</h2>
Step-by-step explanation:
E is correct!!
- See in A the first option -2 will become equal so it will be wrong
- and in B one option that is 0 is missing
- and in c again -2 will be equal to -2
- in d 7 is greater than 6
But in E all are correct!!
So answet is option e

dont murder me if my math is wrong....
Given:
The function is
Domain = {-4, -2, 0, 2}
To find:
The range of the given function for the given domain.
Solution:
We know that domain is the set of input values and range is the set of output values.
We have, and domain = {-4, -2, 0, 2}.
Putting x=-4 in the given function, we get
Putting x=-2 in the given function, we get
Putting x=0 in the given function, we get
Putting x=2 in the given function, we get
The output values are -7, 1, 9, 17. So, the range of the function f(x) for the given domain is {-7, 1, 9, 17}.
Therefore, the correct option is D.
Answer:
4.5
Step-by-step explanation:
Given:
Sample size, n = 40
Sample mean, xb = $6.88
Population std. deviation, σ = $1.92 (known)
Confidence interval = 90%
Assume normal distribution for the population.
The confidence interval is
(xb + 1.645*(σ/√n), xb - 1.645*(σ/√n)
= (6.88 + (1.645*1.92)/√40, 6.88 - (1.645*1.92)/√40)
= (7.38, 6.38)
Answer: The 90% confidence interval is (7.38, 6.38)
