Answer:
x=-7
Step-by-step explanation:
so if you multiply two negative numbers you get a positive and and -7 * -3 is just doing 3*7 which is 21 and that is the answer to -3*-7 and 21 minus 5 is 16 so there´s that and hope this helps
The IQR is the difference between Q3 and Q1.
First we need to get the data from the stem and leaf plot:
10, 23, 23, 28,] [33, 45, 80, 90
Since there are 8 data items Q1 would be the median of the lower half (4 items), both are 23 so Q1 is 23.
Q3 is the median of the upper half, since the middle numbers are not the same we need to average 45 and 80. (45 + 80)/2 = 62.5 so Q3 = 62.5
IQR = 62.5 - 23 = 39.5
Answer:
x=−7
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
I think it’s 90 just add them up the subtract 180
It would be 14 because 3x is the bisect of BD and 42 is
