I assume you mean 9+52,
If so you can add the 9 and the 2 together:
9+2 = 11
Then you can add the 11 on to the 50 to get the final answer:
50+11 = 61
Hope this helps! :)
Answer:
The length of the blue-and-yellow macaw is 42 in
Step-by-step explanation:
Let
x ----> the length of the toucan in inches
y ----> the length of the blue-and-yellow macaw in inches
we know that
----> equation A
----> equation B
substitute equation B in equation A and solve for y

Multiply by 3 both sides to remove the fraction

Divide by 2 both sides

therefore
The length of the blue-and-yellow macaw is 42 in
Step-by-step explanation:
this can't be solved in absolute numbers, only in relative expressions :
Honey is x years old.
Lisa is x+5 years old.
Candy is x-3 years old.
Answer:
a) P(X = 75) = 0.30
(b) P(X ≤ 75)
= 0.2 + 0.4 + 0.3 = 0.90
(c) P(X > 50).
= 0.3 + 0.1 = 0.40
(d) P(X < 100)
= 0.2 + 0.4 + 0.3 = 0.90
(e) parts b, c & d are CDF
