Answer:
21 matches
Step-by-step explanation:
This is a combination problem where we have to select two member out of 7 members
So we want calculation of 7C2
7C2 = 7!/[(2!)(7-2)!]
(7*6*5*4*3*2*1)/[(2*1) *(5*4*3*2*1]
(7*6)/2 ~ Note everything that easily cancels here!
42/2
21 matches
The right answer for the question that is being asked and shown above is that:
Two numbers have a sum of 71 and a difference of 37
x + y = 71
x - y = 37
So in order to get the two numbers, here it is:
x + y = 71
x - y = 37
------------
2x = 108
x = 54
y = 71 - 54
y = 17
<span>So the two numbers are 54 and 17</span>
Answer:
g = 23/16
Step-by-step explanation:
3/16 = (-5/4) + g
g = 5/4 + 3/16
g = 23/16
Answer:
Interquartile Range = 34
Range = 55
Step-by-step explanation:
Max - Min = Range
75 - 20 = 55
Quartile 3 - Quartile 1 = IQR
68 - 34 = 34
Say n = the number.
n * 32% = 25
25/32% = n
n = 78.125
