Answer:
-563
Step-by-step explanation:
a = -7 , b = 9 , c = 4
9ab +C
9 × -7 × 9 + 4
81 × -7 + 4
-567 + 4
-563
Ratio of the radii = sqrt16 / sqrt81 = 4/9
so radius of circle Q is found by solving 4/9 = 8/x where x = radius of Q
x = 2*9 = 18
radius of circle Q = 18.
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:
1) 12
2) Yes, there could be 16 people
3) 1/2 of one segment which is 1 block or 2 skinny blocks
4) 1/12
5) 1 of 4 people -> This means that each person gets 1.5/6 pieces which is greater than 0.66/12 piece
1.5/6 = 3/12 which is greater than 0.66/12 piece
