Answer:
2y
Step-by-step explanation:
"the product between a number y and 2" is written as 2y.
Answer:
Step-by-step explanation:
(5,-4) (4,0)
y2 = 0, y1 = -4, x2 = 4, x1 = 5
Slope m = (y2 - y1)/(x2 - x1)
m = (0 + 4)/(4 - 5)
m = 4/-1
Slope m = -4
And the equation is
y - y1 = m(x - x1)
y + 4 = -4(x - 5)
y + 4 = -4x + 20
y = -4x + 20 - 4
y = -4 + 16
That is the equation of line
So comparing with y = mx + c
C = y intercept = 16
Answer:
Step-by-step explanation:
Let x be a random variable representing the products are rejected
because they contain some technical
problems. This is a binomial distribution since the outcomes are two ways. It is either they are rejected or accepted. The probability of success(that they would be rejected), p = 0.2
The probability of failure, q would be 1 - p = 1 - 0.2 = 0.8
n = 11
a) We want to determine P(x < 3)
From the binomial distribution table,
P(x < 3) = 0.62
b) We want to determine P(x ≥ 3)
From the binomial distribution table,
P(x ≥ 3) = 0.38
c) The number of rejects that the sample is expected to contain is the mean.
mean = np
mean = 11 × 0.2 = 2.2
Approximately 2 rejects
