Answer:
Option D is correct
The point slope intercept equation of line = 
Step-by-step explanation:
Given: The slope of line (m) = 2 and also it is given from the figure the
Point-slope intercept form: If we have a point
and a slope, m, then the formula
we use to find the equation of a line:
.......[1]
Substitute the value of m =2 and (1, 9) in [1];

Therefore, the point slope intercept equation of the line is: 
Answer: Variance = 0.858
Step-by-step explanation: The variance formulae for a probability distribution is given below as
Variance = √npq
Where n = number of times experiment was performed = 9
p = probability of success = 0.09
q = probability of failure = 1 - p = 1 - 0.09 =0.91
Variance = √9×0.09×0.91
Variance = √0.7371
Variance = 0.858

Answer:
b. 28,300
Step-by-step explanation:
The estimated number of 11th grade students in the state is ...
(1600 classes)(27 students/class) = 43,200
About 34.6% are estimated to have 2 or more siblings, so the remaining 100%-34.6% = 65.4% are estimated to have fewer than 2 siblings.
Translated to a number of students, that percentage is ...
0.654 × 43,200 = 28,252.8 ≈ 28,300
A good estimate of the number of students with fewer than 2 siblings is 28,300.
