Answer:
As p-value = 0.0.68 > 0.05 the null hypothesis could not be rejected
Step-by-step explanation:
The computation of the p-value is shown below:
Given that
Average life = 
= 88.5
Standard deviation = 
= 9
Sample = n = 80
Based on the above information
Null and alternative hypothesis is
Now for the level of significance 
= 0.05 and the critical value for a right talied test is 
Now the test statistic is
= 1.491
Now it is observed that
Z = 1.49≤z_ c = 1.64
So by this the null hypothesis could not be rejected
So,
P -value = 1 - P(z<1.491)
P-value = 0.068
As p-value = 0.0.68 > 0.05 the null hypothesis could not be rejected
Your answer would be -0.6 cm.
just take -2.4/4
= -0.6
It is -2.4 because his height decreased each year.

Answer:
d
Step-by-step explanation:
A segment joining the midpoints of a triangle is
• Parallel to the third side
• Half the length of the third side
The segment DF joins the midpoints of 2 sides of Δ ABC , then
BC = 2 × DF = 2 × 4 = 8
The cross section is a rectangle, which is a type of square.
Since you did not give the picture of the problems so it is difficult to solve the problem. but i think this problem is about similar triangles, similar triangle are triangles that have corresponding angles are congruent and their sides are in proportion.
( x / 24) = 30 /18
x = 24 ( 30 / 18 )
x = 40 ft
