When a reflection occurs, the original graph and the reflected graph are mirror images of each other. So, when the graph is reflected about the y-axis, think of the y-axis as the mirror. When you fold the graph length-wise, you will see that both graphs would coincide. Thus, their y-coordinate would not change. It would only change to the opposite quadrant, thereby changing the signs of the x-coordinates. So, as a rule, during reflection, the coordinates (x,y) is changed to (-x,y).

Therefore, the answer is:<span>The x-coordinates' signs change..</span>

Make a conditional relative frequency table for The Columns of movie type. Determine which statement has the strongest associati
Vikentia [17]

Answer: Option A.

Step-by-step explanation:

The association can be found as the quotient between the elements with a given characteristic and the total number of elements.

For example, in option A we have:

A. Females prefer drama movies.

There are 72 females who like drama movies, and there is a total of 126 females, the quotient is:

Q = 72/126 = 0.57

This is the relative frequency of females who like's drama movies

Then the relative frequency table will be something like:

Males:

who prefer comedy: Q = 45/125 = 0.36

who prefer drama: Q = 15/125 = 0.12

who prefer thriller: Q = 65/125 = 0.52

Females:

who prefer comedy: Q = 36/126 = 0.29

who prefer drama: Q = 72/126 = 0.57

who prefer thriller: Q = 18/125 = 0.14

Now we want to answer, which one of the given options has the strongest association.

As larger is the value Q, larger is the association.

We can clearly see that, from the given options, the strongest association is for females who prefer drama, then the correct option is A.

Your state charges 5% sales tax on nonfood items. You're buying a light bulb for $3.00, cereal for
dimulka [17.4K]
We first add the tax to the non-food items.  We have ($3.00+$.50)*1.05=($3.50)*1.05=$3.675 (Which can be rounded up to $3.68, since we can't have a fraction of a cent).

Now, we add the cost of the food to $3.68.  As a result, we have $3.68+$2.50=$6.18 as the total bill.
