Answer:
g(x) = -∛(x-7)
Step-by-step explanation:
Reflection in the y-axis changes the sign of x, so after this transformation, the function is ...
g(x) = f(-x)
Then, translation 7 units to the right replaces x by (x-7), so after both transformations, the function is ...
g(x) = f(-(x -7)) = f(-(x -7))
Using the given definition for f(x), we have ...
Answer:
<em>70%</em>
<em></em>
Step-by-step explanation:
Given
Number of Siblings: || 0 || 1 || 2 || 3
Number of Students: || 4 || 18 || 10 || 8
Required
Determine the probability of a student having at least one but not more than 2 siblings
First, we have to determine the total number of 10th grade students
The probability of a student having at least one but not more than 2 siblings = P(1) + P(2)
Solving for P(1)
P(1) = number of students with 1 sibling / total number of students
From the given parameters, we have that:
Number of students with 1 sibling = 18
So:
Solving for P(2)
P(2) = number of students with 2 siblings / total number of students
From the given parameters, we have that:
Number of students with 2 siblings = 10
So:
Take LCM
Divide numerator and denominator by 4
Convert to percentage
<em>Hence, the required probability is 70%</em>
