Answer:
0.384
Step-by-step explanation:
pet supplier has a stock of parakeets of which 20% are blue parakeets
20/100 = 0.2 blue parakeets (success)
1-0.2 = 0.8 not parakeets (not success)
A pet store orders 3 parakeets from this supplier
we need to find the chance of getting exactly one blue from 3 parakeets
n=3, r=1, p = 0.2 , q=0.8
0.384
Answer:
The commutative property states that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer. The property holds for Addition and Multiplication, but not for subtraction and division.

Find the mean, median mode and range of: 75, 80, 60, 90, 85, 80, -7, 90, 70, 65

Answer:
Mean: 68.8.
Median: 77.5
Mode: 80, 90
Step-by-step explanation:
-7 + 60 + 65 + 70 + 75 + 80 + 80 + 85 + 90 + 90 = 688. Then divide by 10 because there are 10 numbers.
-7 + 60 + 65 + 70 + 75 + 80 + 80 + 85 + 90 + 90
(75, 80) are the middle numbers, so add them both, then divide by 2.
80, 90 appear more than the other numbers.
Range is highest - lowest. 90 - (-7) = 97, or it could be 83. I don't know.
Answer:
cos x = 0.5
Step-by-step explanation:
Using the trigonometric identity
cot x = 
Given
sin x cot x = 0.5, then
sin x × = 0.5 ← cancel sin x on numerator/ denominator
cos x = 0.5
