The answer to you question is B
Answer:
Option A
Step-by-step explanation:
Let the height of plant is 'b' units.
Graph representing the height of the plant will have y-intercept = b units
Since, the plant is growing at the same rate every week,
And growth of the plant is continuous.
Therefore, graph will be a straight line and continuous.
Since, the height of the plant is always increasing,
Slope of the line will be positive.
Option A will be the answer.
Answer: The mean number of checks written per day 
Standard deviation
Variance 
Step-by-step explanation:
Given : The total number of checks wrote by person in a year = 126
Assume that the year is not a leap year.
Then 1 year = 365 days
Let the random variable x represent the number of checks he wrote in one day.
Then , the mean number of checks wrote by person each days id=s given by :-

Since , the distribution is Poisson distribution , then the variance must equal to the mean value i.e. 
Standard deviation : 
Answer:
Step-by-step explanation:
The formula for determining the length of an arc is expressed as
Length of arc = θ/360 × 2πr
Where
θ is the central angle formed at the center of the circle.
r represents the radius of the circle.
π represents a constant whose value is 3.14
From the information given,
r = 21 inches
θ = 25 degrees
Length of arc formed = 25/360 × 2 × 3.14 × 21 = 9.2 inches,
