So these are decmials of the accutal total so
.32=32%
what makes this question easy is that there are 200 members so to convert the percents into accutall numbers so like .32=32%=64 people (since 200 is 2 times of 100)
A. fiction of 31-40 compared to 21-30
fiction 31-40=.38=38%=76 readers
fiction 21-30=.32=32%=64 readers
76-64=12
A is FALSE
B. so we want to know how many people are 31-40 and prefer fiction
so .38=38% and 38% of 200=76
B is FALSE
C 43 members are 21-30
so we look at the total row for the 21-30 people and see that .43 or 43% or 86 people are in the 21-30 age group
C is FALSE
D. 140 members prefer fiction
look at the total column for fiction and see that .70 like fiction .70=70%=140 people
D is TRUE
so A,B,C are FALSE
D is TRUE
Answer x=-2,-6
The roots (zeros) are the
x
x
values where the graph intersects the x-axis. To find the roots (zeros), replace
y
y
with
0

Hi, I'd be glad to help you with this equation.
The answer is (x = 4)
Hope this helps.
Have a great day!
Answer:
see explanation
Step-by-step explanation:
The mean of a set of data is calculated using
mean =
, that is
= 7.1
37.5 + y = 7.1 ( multiply both sides by 6 )
37.5 + y = 42.6 ( subtract 37.5 from both sides )
y = 5.1
-3/5x+y=-8/5 but you have to change all the signs bc an standard formula needs to have a positive x so it would be: 3/5x-y=8/5
