A construction company has two divisions: ceilings and floors. The amount of revenue for the ceiling division, C, is approximately Normally distributed with a mean of $2.6 million per year and a standard deviation of $0.9 million per year. The amount of revenue for the flooring division, F, is approximately Normally distributed with a mean of $3.1 million per year and a standard deviation of $1.1 million per year. Assume C and F are independent random variables.
What is the probability that the ceiling division makes more revenue than the flooring division in a randomly selected year?

Find the value of x.
Answer:
11
Step-by-step explanation:
All angles on a triangle equal 180. 80+60=140.
Now to solve for x, we set it to equal 40 for 180-140.
40=3x+7. 40-7=33
33=3x 33/3=11
x=11

A food production company is choosing between two suppliers of grain. Supplier A sells grain for $5.25 per bushel plus
a
delivery fee of $3 per bushel. Supplier B sells the grain for $6.50 per bushel plus a flat delivery fee of $1,500 each week.
Which supplier would cost more if the production company bought 500 bushels of grain each week?
Answer:
Supplier A: 5.25 per bushel and deliver fee of 3 per bushel
Supplier B: 6.50 per busher and flat delivery fee of $1500 each week
500 bushels of grain each week.
Supplier A: 5.25x + 3x = 5.25(500) + 3(500) = 2,625 + 1,500 = 4,125
Supplier B: 6.50x + 1500 = 6.50(500) + 1500 = 3,250 + 1,500 = 4,750
Supplier B would cost more if the company buys 500 bushels of grain per week.

Answer:
Y = 28.31
Z = 13.29
Angle A = 28
Step-by-step explanation:
For Angle A:
Remember a triangle has a total of 180 degree angles. So set up your formula as
180 - 62 -90 = Angle A
For Y:
The sine of an angle is equal to the ratio of the opposite side to the hypotenuse.
sin (B) = opp/hyp or b/c or (y)
sinB = 62
b = 25
Rewrite as c=b/2SinB -> c=25/sin62 -> Y = 28.31
For Z:
Use the Pythagorean theorem to find the unknown side.
[tex]z^{2} = 28.31^{2} - 25^{2}[/tex]
z = 13.29
Someone please help! I’ll give brainliest!!
Answer:
The answer is 65.97 yd^3
Step-by-step explanation:
The volume of a cone is: v = [tex]\pi r^{2}\frac{h}{3}[/tex]
So, v = [tex]\pi[/tex](3^2)(7/3) = 65.97345 yd^3
The measures of the angles of a triangle are shown in the figure below. Solve for x.
Answer:
51 degrees
Step-by-step explanation:
All right angles are 90 degrees and all triangles interior angles add up to 180.
39+90=129
180-129=51
Please Help!!! What is x and do I find it?
TIMED TEST PLEASE HELP!!!!! Explain how you got the answer as well!
Answer:
Step-by-step explanation:
Perimeter= all sides added together
so in this case
3x+1 = 2x + 2x + x-1 + x+2 + x-1 + x + 2
now you may be wondering why i put two 2x's, two 2+x, and two x-1 , the far left side is 2x and has 2 lines and so does the bottom side which has 2 lines so theyre congruent ( the same case for the 2+x and x-1 ) so you need to account for all sides.
so lets simplify this huge equation!
3x+1 = 4x + 1x - 1 + 1x + 2 + 1x - 1 + 1x + 2
3x+1 = 8x - 1 + 2 - 1 + 2
3x + 1 = 8x + 2
-3x on both sides
1 = 5x + 2
-2 on each side
-1 = 5x
x = -1/5

Mark's father was putting in a new kitchen floor. The dimensions were 8 feet by 12 feet. If each tile was 1 square foot, how many tiles did he need?
Answer:
96 tiles
Step-by-step explanation:
The kitchen floor is rectangular on shape.
The dimensions of the kitchen floor were 8 feet by 12 feet.
Hence, Area of a rectangle = Length × Width
Length = 8ft
Width = 12ft
Hence:
Area = 8ft × 12ft
= 96 ft²
If each tile was 1 square foot, the number of tiles he would need is
1 ft² = 1 tile
96 ft² = x
Cross Multiply
1ft² × x = 96 ft² × 1 tile
x = 96 ft² × 1 tile/1 ft²
x = 96 tiles
Therefore, Mark's father would need 96 tiles

[tex]36[\cos{127^\circ}+i\sin{127^\circ}][/tex]
Step-by-step explanation:
Polar form: [tex]z=r(\cos(\theta)+i\sin(\theta)[/tex]
To multiply two complex numbers in polar form, multiply the r values and add the angles.
[tex]w_1w_2=36\left[\cos{(95^\circ+32^\circ)}+i\sin{(95^\circ+32^\circ)}\right]\\\\=36[\cos{127^\circ}+i\sin{127^\circ}][/tex]

length is 2 cm : 1m.
What is the length of the car in Ivan's scale drawing?
Answer : 12cm
Step-by-step explanation:
Answer:
im thinking its 12
Step-by-step explanation:

you have a bucket that contains 3 red baseballs , 4 white baseballs, and 5 green baseballs. you are going to pick out one baseball, leave it out, and then pick another baseball. what is the probability of picking out a white baseball followed by a green baseball?
Answer:
probably a 60%
Step-by-step explanation:
Answer:
5/44
Step-by-step explanation:
3 plus 4 plus 5 is 12 so for a white it is 4/12 or 1/3
then you take out the white baseball and you want a green which is 5/11 3 red 3 white 5 green
5/11 times 1/3 is 5/33
so the odds of picking both is 5/33
