Hello,
The correct answer is D) 2
Median: To find the Median, place the numbers you are given in value order and find the middle number. Example: find the Median of {13, 23, 11, 16, 15, 10, 26}. Put them in order: {10, 11, 13, 15, 16, 23, 26} The middle number is 15, so the median is 15. (If there are two middle numbers, you average them.)
The median number of trips taken to the food store in 1 week is 2.
4 - 2 = 2
Hope this helps!!!! :)
The different type of discount effected on the prices of two similar products having the same unit price may either increase or decrease the total unit price on the discounted sale price of the items.
Taking an hypothetical scenario :
50 ml of Product A = $100
60 ml of product A = $100
<u>Discount on sale of 60ml size on purchase of two or more units </u> : 10% off
Discounted price of 60 ml size :
Initial product cost on purchase of 3 units = ($100 × 3) = $300
Discounted price = (100 - 10)% × $300 = $270
<u>Discount on sale for 50ml size on purchase of two or more units</u> : $20 off
Discounted price of 50ml size :
This means $20 is deducted from any purchase of two or more units ;
Hence, purchasing 2 units of the 50 ml product will cost ; (
($100 × 2) - $20
$200 - $20 = $180
Therefore, the discount effected on the cost of product which has the same unit price may either decrease or increase the total cost of one product relative to the other.

How to determine the value of sin(2x)
The cosine ratio is given as:
\cos(x) = -\frac 14cos(x)=−

Calculate sine(x) using the following identity equation
\sin^2(x) + \cos^2(x) = 1sin
2
(x)+cos

(x)=1
So we have:
\sin^2(x) + (1/4)^2 = 1sin
2
(x)+(1/4)

=1
\sin^2(x) + 1/16= 1sin
2
(x)+1/16=1
Subtract 1/16 from both sides
\sin^2(x) = 15/16sin
2
(x)=15/16
Take the square root of both sides
\sin(x) = \pm \sqrt{15/16
Given that
tan(x) < 0
It means that:
sin(x) < 0
So, we have:
\sin(x) = -\sqrt{15/16
Simplify
\sin(x) = \sqrt{15}/4sin(x)=

sin(2x) is then calculated as:
\sin(2x) = 2\sin(x)\cos(x)sin(2x)=2sin(x)cos(x)
So, we have:
\sin(2x) = -2 * \frac{\sqrt{15}}{4} * \frac 14sin(2x)=−2∗
