This means that the probability of picking both red and blue balls would have to be 60% or 0.6
Answer:
A) y= 40x+100
B) 
Step-by-step explanation:
To solve this, we can set up an equation using y=mx+b.
'b' is the initial cost, whereas 'm' is the monthly cost. This gives us the equation:
A): y=40x+100.
For part B, we can solve for the inverse by switching the x and y. This gives us:
x= 40y+100
Now, continue simplifying to isolate the 'y' on a side:
x-100=40y

Let us find the area of the triangle first.
6 x 8 / 2 = 24 ft²
Now we can do the semi circle. Note that it is a semi circle and not a circle.
1/2π(4²) = 8π = 25.12 ft²
Add the areas up to find the area for the figure.
24+25.12 = 49.12 ft²
If a, b and c are the lengths of the sides of a triangle then
if a ≤ b ≤ c, then a + b > c.
1. a ≤ 3 ≤ 8 then a + 3 > 8 → a > 8 - 3 → a > 5 FALSE, because a ≤ 3.
2. 3 ≤ a ≤ 8 then 3 + a > 8 → a > 5 therefore 5 < a ≤ 8
3. 3 ≤ 8 ≤ a then 3 + 8 > a → 11 > a → a < 11 therefore 8 ≤ a < 11.
<h3>Answer: 5 < a < 11 → S = (5, 11)</h3>
