Answer:
There is 33.33333% That are girls.
Step-by-step explanation:
single die is rolled twice. The set of 36 equally likely outcomes is {(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6), (2, 1), (2
VMariaS [17]
The highest sum you would get with 2 dice rolls would be 6 + 6 = 12
so the probability of getting two numbers whose sum is less than 13 is 100%
Answer:
<h3> y = 2x² - 4x - 6</h3>
Step-by-step explanation:
y + 4x + 6 = 2x²
-4x -4x
y + 6 = 2x² - 4x
-6 -6
y = 2x² - 4x - 6
A.)
The first thing we must do for this case is to find the area of the complete figure.
We have then:
Triangle 1:
A1 = (1/2) * (1.5) * (1)
A1 = 0.75 feet ^ 2
Triangle 2:
A2 = (1/2) * (1.5) * (2)
A2 = 1.5 feet ^ 2
Triangle 3:
A3 = (1/2) * (0.75) * (1)
A3 = 0.375 feet ^ 2
Rectangle:
A4 = (5) * (0.75)
A4 = 3.75 feet ^ 2
Adding the areas we have:
A = A1 + A2 + A3 + A4
A = 0.75 + 1.5 + 0.375 + 3.75
A = 6.375 feet ^ 2
Answer:
there are 6,375 feet ^ 2 of plywood in the scenery
B.)
Triangles:
A = A1 + A2 + A3
A = 0.75 + 1.5 + 0.375
A = 2,625 feet ^ 2
Two layers of paint:
A = 5.25 feet ^ 2 <45 feet ^ 2
Rectangle:
A = 3.75 feet ^ 2
Two layers of paint:
A = 7.5 feet ^ 2 <45 feet ^ 2
Answer:
One quart of each color is needed.
Answer:
Step-by-step explanation:
cos θ=12/16=3/4=0.75
θ=cos^{-1}(0.75)≈41.4°
