Answer:
20
Step-by-step explanation:
Assume n is the number of times she pick a skittle out of the bag
The probability she pick out red : 8/n
The probability she pick out yellow : 12/n
=> The ratio of red and yellow skittle : 8/n : 12/n = 8/12 = 2/3, means every 2 red skittles we have 3 yellow ones.
But we have 50 skittles, so the likely numbers of reds in the bag is = 2*
= 20
x= | 1 < x < 3
x + 2 < 5 and x - 7 > -6
x < 5 - 2 and x > -6 + 7
I don't know if I am 100% right.
Width = w
length,l = 2w + 1
perimeter, p
p = 2w + 2l
92 = 2w + (2*(2w+1))
92 = 2w + 4w + 2
92 = 6w + 2
6w = 90
w = 15
so length of the garden
2w + 1
2*15 + 1
31 feet
We can find the midpoint with this formula
x-midpoint = (x₁ + x₂)/2
y-midpoint = (y₁ + y₂)/2
From the question we know that,
(x₁, y₁) = (1.3, 3.7)
(x₂, y₂) = (0.7, -1.4)
Plug the numbers into the formula
x-midpoint = (x₁ + x₂)/2
x-midpoint = (1.3+0.7)/2
x-midpoint = 4/2
x-midpoint = 2
y-midpoint = (y₁ + y₂)/2
y-midpoint = (3.7 - 1.4)/2
y-midpoint = 2.3/2
y-midpoint = 1.15
The midpoint is (2, 1.15)
