Answer:
c. One sided t-test
Step-by-step explanation:
One sided t test because we want to compare two means and alternative hypothesis is directional.
Answer:
4(3x+2)
Step-by-step explanation:
Just factor the expression.
Answer:
C) x ≥ 11 or x ≤ -3
Explanation:
Given following: |x − 4| ≥ 7
Apply absolute rule: If |u| ≥ 0 then u ≤ -a, u ≥ a
Solving stepwise:
⇒ x - 4 ≤ -7, x - 4 ≥ 7
<u>change sides</u>
⇒ x ≤ -7 + 4, x ≥ 7 + 4
<u>add/subtract integers</u>
⇒ x ≤ -3, x ≥ 11
Answer:
4x - 1 and x + 6 are the factors of given Trinomial
Step-by-step explanation:
The given Trinomial is:

We can factorize this trinomial by mid-term splitting. The mid-term(23x) can be split up in two terms (24x and -x) such that their sum is 23x and their product(-24x²) is equal to the product of other two terms (4x² and -6)
So, the above expression can be written as:

Therefore, 4x - 1 and x + 6 are the factors of given Trinomial
Answer:
x = 250,000
Step-by-step explanation:
A = P(1 + rt)
550,000 = x (1 +2% x 60)
550,000/(1 +2% x 60) = 250,000
x = 250,000
<u>Check your answer</u>
A = 250,000 (1+2%x60)
A = 550,000
