Answer:
C. 7x+10
Step-by-step explanation:
First, distribute the 2
2(x+5) +5x
2*x+2*5 +5x
2x+10+5x
Combine like terms
2x+5x+10
7x+10
So, C is the correct answer
Hope this helps! :)
Answer:
FAIL TO REJECT
NOT ENOUGH
Step-by-step explanation:
Given a Pvalue of 0.32
Decision region :
When Pvalue < α ; Reject the Null and conclude that there is significant or enough evidence to accept the alternative hypothesis.
Otherwise, fail to reject reject the null and conclude that, there is not enough evidence to accept the alternative hypothesis
Therefore, for the scenario above, where Pvalue = 0.32
Possible α values are ; 0.1, 0.05, 0.01
For all α - values listed, the Pvalue is greater than α
Pvalue > α ; Hence, FAIL TO REJECT the Null.
Conclusion :
There is NOT ENOUGH evidence to support the alternative that the proportion of students who have ear infection at one school and the other is different.
Answer:
The answer to your question is w = 1.2
Step-by-step explanation:
Data
Equation 7(w + 2) + 0.5w = 5
Expand 7w + 14 + 0.5w = 5
Simplify like terms (7w + 0.5w) + 14 = 5
7.5w + 14 = 5
Subtract 14 in both sides
7.5w + 14 - 14 = 4 - 15
Simplify
7.5w = - 9
Divide both side by 7.5 7.5/7.5w = 9/7.5
Simplify
w = 1.2
N = first integer
n + 1 = second integer
n + 2 = third
n + 3 = fourth
the sum is 114 so:
n + (n + 1) + (n + 2) + (n + 3) = 114
solve:
4n + 6 = 114
4n = 108
n = 27
so 27 is your first.
27 + 1 is your second (remember n +1 n +2 and n +3)
so your first four integers are: 27 28 29 and 30
(I'll also help with one)
week one: x
week two: x + 5
week three: 2(x+5) or 2x + 10
week1 + 2 + 3 = 431
so its:
x + (x+5) + (2x + 10)
4x + 15 = 431
4x = 416
x = 104
its then:
week one: 104 sold
week two: 109 sold (x + 5)
<span>week three: 218 (2x + 10)
