The inspector can expect to find 450 units in a batch of 3000 phones
Step-by-step explanation:
Given
Total Cellular Phones = S = 60
Defective phones = E = 9
We will calculate the probability of defective forms first
So,
The probability of defective phones in 60 phones is 0.15
Now,
Total phones = 3000
The inspector can expect to find 450 units in a batch of 3000 phones

Answer:
y = (x + 3)² - 6
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Given
f(x) = x² + 6x + 3
Using the method of completing the square
add/subtract ( half the coefficient of the x- term)² to x² + 6x
f(x) = x² + 2(3)x + 9 - 9 + 3
= (x + 3)² - 6 ← in vertex form
Answer:
B
Step-by-step explanation:
The total % of $20 is 43% which is $3.6
