Hello from MrBillDoesMath!
Answer:
w = 5
Discussion:
48 = 2 (2w) + (4 + 2w)2 =>
48 = 4w + 4*2 + (2w)*2 =>
48 = 4w + 8 + 4w => as 4w + 4w = 8w
48 = 8w + 8 => subtracting 8 from each side
48 - 8 = 8w => divide both sides by 8
(48 -8 )/8 = w =>
40/8 = w =>
w = 5 =>
Check: 2(10) + ( 4 + 2*5)*2 = 20 + 14*2 = 20 + 28 = 48
Thank you,
MrB
Answer:
Step-by-step explanation:
First order from smallest to largest.
70.8, 71.9, 72.1, 82.4, 85.3, 98.1.
Median is the middle number/s.
72.1+82.4/2 so The median is 77.25
Range is the largest number minus the smallest number.
85.3-70.8=14.5
Mode is the most repeated number.
Since there are no repeated numbers there is no mode.
Second question:
Again rearrage: 6, 9, 11, 14, 17
In order to make the median 10 you would have to add another 9 becasue
11+9/2 = 10
Third: remove 6 to make 12 the middle number
Fourth: add all numbers 90+x/6=20 so x has to be 30
To answer this question, an assumption must be made, that Eva spends 8 hours a day working. If this is the case, then Eva will complete jobs w, x, and v on day one, for a total of six hours. Since the next job (y) requires 4 hours, she will spend two hours working that day, leaving 2 more hours to go on that job. The next day she will spend 2 hours finishing job y, completing it, and finish the longest job z (hours) that day. This means she had 4 jobs on day one, and 2 jobs on day 2 for and average of 3 jobs per day.
This answer assumes an 8 hour work day, and that Eva can start a job she cannot finish that day.
Answer:
1
Step-by-step explanation:
-20 divided by -2 is the same as 20 divided by 2, which is 10. 11-10=1 so the answer is 1.
