Your Student Government Association decided to do a fundraiser to raise

nikklg [1K]

Step-by-step explanation:

If x is the number of t-shirts, and y is the number of sweatshirts:

10x + 15y ≥ 500

x + y ≤ 50

y ≥ x/2

And since x and y can't be negative:

x ≥ 0

y ≥ 0

Graph:

The boundaries of the feasible region are:

(0, 50), (0, 33.3), (28.6, 14.3), and (33.3, 16.7)

Since x and y must be integers, any non-integer solutions are not viable.

The maximum profit will be when the most product is sold. Since sweatshirts are more profitable, we want to sell as much of that as we can.

So they should sell 0 t-shirts and 50 sweatshirts for a maximum profit of $750.

<h3>Answer: 5</h3>

===================================================

Explanation:

Everywhere you see an x, replace it with -5. Then use the order of operations PEMDAS to simplify

$f(x) = -x^2 - 7x - 5\\\\f(-5) = -(-5)^2 - 7(-5) - 5\\\\f(-5) = -(25) - 7(-5) - 5\\\\f(-5) = -25 + 35 - 5\\\\f(-5) = 10 - 5\\\\f(-5) = 5\\\\$

Keep in mind that for the x^2 term, you are squaring all of x = -5, which includes the negative as well. So that means

x^2 = (-5)^2 = (-5)*(-5) = 25

but sticking a negative out front makes

-x^2 = -(-5)^2 = -25

The data for numbers of times per week 20 students at Stackamole High eat vegetables are shown below:

The dot plot uses dots to for data representation.

The dot plot is right skewed
There is an outlier, 9.
The best measure of center is median

(a) The description

From the dot plot (see attachment), we have the following observations,

There are more data at the left-hand side, than the right-hand side of the dot plot.
There is only one data element at the right-hand side

This means that the dot plot is right skewed

(b) Outlier

From the dot plot, we can see that 9 is relatively far from the other data elements.

This means that 9 is outlier

(c) Measure of center

In (b), we established that the dot plot has an outlier.

When there is an outlier, the best measure of center to use is the median.

Hence, the median will be used as the measure.
