Answer:
24
Step-by-step explanation:
To solve the equation, multiply 60 by 2/5.
[Note: 60 can be written as 60/1]
60/1 x 2/5
Multiply the numerators:
60 x 2 = 120
Multiply the denominators:
1 x 5 = 5
Now simplify:
120/5 = 24
So, the correct answer is 24. I hope this helps! :)
K²+11k+30
(k+5)(k+6)
k=-5,-6
Sum of the numbers in the set: 42+37+32+29+20 =160
Current mean: 160/5 = 32
Median = the valvue of the middle = 32.
New mean: 32+10= 42.
Sum of numbers in the new set = 42*8 = 336
Difference: 336 - 160 = 176
I want to include 32, so that the new median stays in 32.
So the other two numbers must add 176 - 32 = 144
I will use a smaller number than 32 and the other greater (again in order to keep the same median.
I will choose 28 and 144 - 28 = 116.
So my three new numbers are 28, 32 and 116 and the new set is {116, 42, 37, 32, 32, 29,28, 20}
Checking:
Sum of the terms: 116+42+37+32+32+29+28+20 = 336
Mean = 336 / 8 = 42, which is 10 more than the original mean.
And the new median is (32+32)/2 = 32. The same of the original set.
