Answer:
y = ⅓x - 3
Step-by-step explanation:
First, find the slope using two points on the line, say (0, -3) and (6, 0):
Slope (m) = ⅓
Find the y-intercept (b):
The line intercepts the y-axis at y = -3. So b = -3
Next, substitute m = ⅓ and b = -3 into y = mx + b (slope-intercept form):
y = ⅓(x) + (-3)
y = ⅓x - 3
Answer: 4
Step-by-step explanation:
For any binomial variable X having parameters n (total number of trials ) and p (probability of getting success in each event), the standard deviation is given by :-
As per given , we have
n= 100 , p= 20%=0.20
Then, the standard deviation of this binomial distribution is :
Hence, the standard deviation of this binomial distribution is <u>4</u>.
