Answer:
j=46
Step-by-step explanation:
34=j-12
add 12 to 34 to isolate j
the answer to that is 46
j=46
Answer:
Step-by-step explanation:
15) should be b) 6.7, 6 as the median is the average of the 25th and 26th result, these both occur in the 6 group and is the only option with a whole number for median
To check the mean
(2(4) + 7(5) + 17(6) + 10(7) + 8(8) + 6(9)) / 50 = 6.66 ≈ 6.7
16) mode is 1 child as the single largest grouping is 11 families
there were 46 families polled so the median occurs between 23 and 24
7 + 11 + 6 is 24 therefore median falls under 2 children.
a) 1, 2
The first raise was a 25% increase, while the second raise was a 32% increase so there was a 7% increase from the first raise to the second one.
Find the g(x) points by plugging in the values of x into 2(x + 3)^2 - 1
so for x - -3 g(x) = 3(-3+3)^2 - 1 = 3(0)^2 - 1 = 0 - 1 = -1
calculate the other values of x -2 , -1 , 0 and 1 in the same way
Answer:
x = -6
Step-by-step explanation:
3x - 4 = 2x - 10
3x - 2x = -10 + 4
x = -6
