Answer:
B
Step-by-step explanation:
If you arrange a statistics in order from least to greatest, the middle number is the median.
If there is even number of numbers in a list, let it be n numbers, then we take the average of n/2th and n/2 + 1 th terms.
Here, all of them have 6 numbers, so 6/2 = 3 and 4th, we take average of 3rd and 4th number to find the median.
Since they are arrange in order we check each:
Jon = average of 6 and 7, (6+7)/2 = 6.5
Leroy = average of 6 and 8, (6+8)/2 = 7
Simon = average of 5 and 6, (5+6)/2 = 5.5
Leroy's median is the greatest (7).
Answer:
A
Step-by-step explanation:
Area of a triangle =
where b = base length and h = height
the triangle shown has a base length of 2 and 1/2 and a height 4. and 2/5
So area =
5.5 also =
Hence, the correct answer is A

Answer: x= -14
Step-by-step explanation:
2x-5(x+4)=-2(x+3)
2x-5x-20=-2x-6
-3x-20=-2x-6
-x-20=-6
-x= -6+20
-x= 14
X=14/-1
X=-14
To check substitute
2(-14)-5(-14+4)=-2(-14+3)
-28-5(-10)= -2(-11)
-28+50=22
22= 22
