f(x) = 5x - 4

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

f(2a) = 5(2a) - 4

f(2a) = 10a - 4

156 = 10a - 4

10a - 4 = 156

Add sides 4

10a - 4 + 4 = 156 + 4

10a = 160

Divide sides by 10

\frac{10a}{10}  =  \frac{160}{10}  \\

a = 16

For a binomial process, the probability of success is 40 percent and the number of trials is 5. Find the variance.
Natalka [10]

Answer:

1.2

The variance of a binomial distribution is:

σ² = n p (1 − p)

where n is the number of trials and p is the probability of success.

Given n = 5 and p = 0.40:

σ² = 5 (0.40) (1 − 0.40)

σ² = 1.2
