Answer:
Step-by-step explanation:
Internal dimensions of the box will be smaller considering the thickness of the wood:
- 21 - 1 = 20 cm
- 11 - 1 = 10 cm
- 7 - 0.5 = 6.5 cm (open top)
<u>The volume is now:</u>
Answer:
A
Step-by-step explanation:
there cannot be 2 different points on the same x coordinate
Answer:
99% confidence interval will be wider because as the level of confidence increase the width increases as well and the standard error decreases
Step-by-step explanation:
The confidence interval is directly proportional to the sample size hence the 99% confidence interval will be wider than the 95% confidence interval of the sample of 120 college students
using a 99% confidence interval gives a more accurate result than a 95% confidence because the standard error decreases with increase in confidence interval

23
Step-by-step explanation:
(g-f)(x)=g(x)-f(x)
=6x-(4-X(2))
=x(2)+6x-4
to evaluate (g-f) (#) substitute x=3 into (g-f)(x)
(g-f)=(9)+(6 x 3) -4=23
Answer:
The height is 2 units
Step-by-step explanation:
Find the area of the base of the square pyramid
we know that
The volume of the square pyramid is equal to
where
B is the area of the base and H is the height of the pyramid
we have
substitute in the formula and solve for B
step 2
Find the height of the square prism
we know that
The volume of the square prism is equal to
where
B is the area of the base and h is the height of the prism
we have
substitute in the formula and solve for h
