Answer:
The likelihood that he or she has a pet given that a student does not have a sibling is:
Option: D ( 60%)
Step-by-step explanation:
Let A denote the event that a student does not have a sibling.
Let B denote the event that a students has a pet.
Then A∩B denotes the event that the student does not have a sibling but has a pet.
Let P denote the probability of an event.
Then, we are asked to find:
P(B|A)
We know that:
Also from the table we have:
P(A)=0.25
and P(A∩B)=0.15
Hence,
which in percentage is:
Hence, the likelihood is:
60%
Answer:
9
Step-by-step explanation:
a²+b
Substituting values,
=> (-2)^2+5
=> 4 + 5
=> 9
Answer:
$6.87
Step-by-step explanation:
For the blueberries we multiply 3.98 with .6 pounds to get 2.39
We do the same for the other item 2.49 X 1.8 = 4.48
Total the two for the answer:
2.39 + 4.48 = 6.87

Now,
Answer:
D. b = 3
Step-by-step explanation:
Given the following data;
Points on x-axis (x1, x2) = 10, 12
Points on y-axis (y1, y2) = 23, 27
First of all, we would determine the slope.
Mathematically, slope is given by the formula;
Substituting into the equation, we have;
Slope, m = 2
The equation of straight line is y = mx + b
Where;
m is the slope.
x and y are the points
b is the intercept.
To find the intercept, we would use the following formula;
y - y1 = m(x - x1)
Substituting into the formula, we have;
y - 23 = 2(x - 10)
y - 23 = 2x - 20
y = 2x - 20 + 23
y = 2x + 3 = mx + b
Therefore, intercept, b = 3
