Answer: the median and they should predict size 8
Step-by-step explanation:
It is this answer because if you put the numbers in order from least to greatest and then start to find the median you will get two answers for the median and the numbers you should get are two 8 so then you add the two 8's up and then you get 16 so then you divide it by 2 and you will get 8 and that is your answer.
Let <em>f</em> and <em>s</em> denote the amounts of the <u>f</u>irst and <u>s</u>econd brands that the chef is going to use.
She wants to end up with 290 mL, so
<em>f</em> + <em>s</em> = 290
Each mL of the first brand contains 0.08 mL of vinegar, and each mL of the second contains 0.13 mL of vinegar. The final mixture should have a concentration of 12% vinegar, so that it contains 0.12 • 290 mL = 34.8 mL of vinegar, and
0.08<em>f</em> + 0.13<em>s</em> = 34.8
Solve for <em>f</em> and <em>s</em> :
<em>f</em> + <em>s</em> = 290 → <em>s</em> = 290 - <em>f</em>
0.08<em>f</em> + 0.13 (290 - <em>f </em>) = 34.8
0.08<em>f</em> + 37.7 - 0.13<em>f</em> = 34.8
0.05<em>f</em> = 2.9
<em>f</em> = 58
<em>s</em> = 290 - 58
<em>s</em> = 232
Each term has a common divisor of 
:
133 = 7*19, so the number in the blanks is .
OK, we'll go in steps. First a reflection through the x axis, which negates y.
Now a vertical scaling of 2/3
Now we shift seven units to the right,
Now down five,
There it is.
Answer: reflection thru x axis, vertical scale 2/3, right shift 7, down 5, second choice
