You'll need to calculate the surface area to be painted. The room has two ends, 2 sides and 1 ceiling. The area of the ceiling is 18*20. The area of the two ends of the room is 2(8*18). The area of the two long walls is 2(8*20)
Add these areas together: 18*20 + 2*8*18 + 2*8*20, or 968.
That's 968 square feet. Since each can contains enough paint for 400 square feet of coverage, divide 968 by 400:
968
----- = 2.42. This means having to purchase 2.5 (gallons)
400 This answer is accurate to the nearest 0.5.
Answer:
Step-by-step explanation:
The center is at (1,-2) from the graph.
The radius is 2 [3 - 1 on the horizontal]
The equation of the circle is
(x - 1)^2 + (y + 2)^2 = 2^2
(x - 1)^2 + (y + 2)^2 = 4
A binomial probability density function should be used to represent the probability
<h3>How to determine the type of
probability density?</h3>
The given parameters are:
- Proportion that plays sport, p = 32%
- Number of students selected, p = 50
- The probability, P = (x ≤ 15)
The proportion that plays sport indicates that
68% of the students do not play sport
So, we have two events, which are
- Play sport
- Do not play sport
When there are two possible events, then the binomial probability density function should be used

Answer:
x=1
y=-3
(1,-3)
Step-by-step explanation:
3x+2y=-3
3x-y=6 then y=3x-6
substitute for y
3x+2(3x-6)=-3
3x+6x-12=-3
reduce
9x=9
x=1
substitute for x
y=3(1)-6
y=-3
Answer:
d. 8°
Step-by-step explanation:
It appears as though you intend ∠ECF and ∠ACB to be vertical angles, hence the same measure, 47°. The angle of interest, ∠BCD, is added to that to make ∠ACD, which is 55°. The added angle must be 55° -47° = 8°.
