Answer:
its the last one D
Step-by-step explanation:
The median is 22 and the rest dont have that as the median
Answer:
x + 15 or 1x + 15
Step-by-step explanation:
Answer: (Supermart) Equation 1 = $2.70÷5 lb = $0.54 per lb
(Market One) Equation 2 = $2.60÷4 lb = $0.65 per lb
Since the unit price of bananas per lb in Supermart is less than the unit price of bananas per lb in Market One, Supermart has the better price.
Answer: Choice A
==========================================================
Explanation:
One shaded region is below the parabola, and the other shaded region is below the line. They both overlap outside the parabola, but under the straight line.
Since both shaded regions are below their respective boundaries, this means that we'll be using "less than" signs for each inequality. The solid boundary lines indicate "or equal to" is part of that as well.
Because of this, the answer is between A and D since both involve inequality signs that have "less than or equal to".
However, we can rule out choice D since the inequality
would have the boundary line
, and this boundary line has a positive slope. But notice how the red diagonal line slopes downward as we read from left to right. Therefore, the red line must have a negative slope. Luckily, choice A has one of the boundary lines as y = -x+3 to fit the description. So that's why choice A is the answer.
The median is the middle number, and we can find that by listing the numbers in order of size.
201, 218, 242, 257, 265, 275, 301. We can see that the middle number is 257, so 257 is the median.
