18 students are 100%-37,5%-40%=22,5%
So we know that 18 students equal to 22.5. And we are looking for the anwser what 100% of students is.
SO:
x students - 100%
(22 + 1/2)x =18×100
(22 + 1/2) can be represented as just 25.5
-//- = 1800
we need to divide bot sides by 25.5
x = 1800 / 25.5
... x = 80
Answer:
The finance charge is 23,028
Step-by-step explanation:
I think you just are supposed to just add and multiply in this case
Answer:
H0: p(1980) = p(2010) ; H1 : P(1980) > P(2010)
0.02
Step-by-step explanation:
Given that:
Sample size in both 1980 and 2010 = 1000 samples :
Proportion in favor :
P(1980) = 0.66
P(2010) = 0.64
To test the hypothesis :
Null hypothesis :
Proportion in favor are the same in both years
Null hypothesis = H0 = p(1980) = p(2010)
Alternative hypothesis :
Proportion in favor in 1980 is greater than that in 2010
Alternative hypothesis = H1 : P(1980) > P(2010)
The sample statistic :
P(1980) - p(2010)
0.66 - 0.64
= 0.02
-3/11
Step-by-step explanation:
7-10/3-(-8)
7-10/3+8
Answer:
They are not similar
Step-by-step explanation:
To see whether the triangles are similar or not we can compare their side lengths:
AB = 24
AX = 6
AX/AB = 1/4 is the ratio now let's compare this to AY/AC
AY/AC = 10/25 if we simplify this the result will be 2/5 as we can see the side lengths are not proportional so the triangles are not similar.
