Answer:
4+3(7+4*2) - 100 = -51
Step-by-step explanation:
4+3(7+4*2) - 100
= 4 + 3 (15) - 100
= 4 + 45 - 100
= -51
Answer: 14
Step-by-step explanation:
We know that 
by SAS, so this means 
by CPCTC. Hence, 
.
We also know that 
by SAS, so this means 
by CPCTC. Since 
, <u>TQ=14.</u>
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.
Answer:x=20
Im pretty sure thats the answer
3 because when you do the measurements its just above 3
