Answer:
Step-by-step explanation:
20,24,25,27,31,35,38
minimum;20
medium: 27
maximum: 38
lower quartile: 24
upper quartile:35
put numbers in number order
the first number is the minimum, the last number is the maximum. the middle number "split" is the median.
quartiles are the numbers in the middle of the data you just "split"
(so like a quarter)
i may be wrong i haven't done this in years
12
13
78
97
65
90
70
these are numbers with 2 digits
Answer:
x = approx. 1.24 or -7.24
Step-by-step explanation:
It's hard to factor directly so we should use the quadratic formula or complete the square. I'm going to go with completing the square.
x²+6x-9=0
x²+6x=9
x²+6x is the same as x²+2·3·x, in order to make this into the algebraic identity (A+B)²=A²+2AB+B², we must add B², or in this case 3² to both sides. (A is x, B is 3)
x²+6x+9=18
(x+3)²= 18
x+3= ±√18
x= ±4.24 -3 (approximately 4.24)
First solution for x = 4.24-3 = 1.24
Second solution for x = -4.24-3 = -7.24
Answer:
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
