Answer:
A class has been omitted.
Explanation:
Given the frequency distribution shown in the attached table.
the frequency distribution is incorrectly constructed because a class has been omitted.
On the given table the class 133-137 is missing on the frequency distribution table.
Total amount paid by Rita is $98.79
Step-by-step explanation:
- Step 1: Given sales tax = 11% and cost of jeans = $89
- Step 2: Calculate amount of sales tax = 11% of 89 = 11/100 × 89 = $9.79
- Step 3: Calculate the total amount
Total Amount = 89 + 9.79 = $98.79
Answer:
f(x) = |x|
g(x) = |x| - 2
h(x) = |x| + 3
Step-by-step explanation:
All the functions graphed represent the absolute value functions.
Since function g(x) passes through (0, 0) and (1, 1),
Let the equation of a line passing through these points is,
y = mx + b
Slope of the line passing through these points 'm' = 
m = 1
y-intercept of the line 'b' = 0
Therefore, equation of the line will be,
y = x
And the function representing the two lines (both are the mirror images) joining at the origin will be,
f(x) = |x|
When the parent function is shifted 3 units up, the new function will be
h(x) = |x| + 3
When the parent function is shifted 2 units down,
g(x) = |x| - 2
Add the total of both groups and divide by the total number in each group
Group X = 535 / 18 = 29.72 mean
group Y = 500 / 18 = 27.78 mean
Group X has the higher mean
