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
Answer: x^2−xy+1
Step-by-step explanation:
simplify:
5+x^2−xy−4
5+x^2+−xy+−4
Combine Like Terms:
5+x^2+−xy+−4
(x^2)+(−xy)+(5+−4)
x^2+−xy+1
If we were to simplify this it would equal the same equation because this cannot be solved. Due to there being no like terms. We also need to know what x equals which there is no number given here to solve. Have a great day!
Answer:
V= 8
x=4.5
BCF =48 CFE=132
V=352.8 =8.4x8.4x5
For the volume one i cant read the number but if the bottom number is 8 then V=803.84
if its 6 then v = 452.16
Step-by-step explanation:
v= 2x2x2 v = 8
x is 11x-9=7x+9 | 4x=18 | x=4.5
15x=180 x=12 | CFE = 11x12=132 | BCF = 4x12=48
The value of x will be 6
<u><em>Explanation</em></u>
According to the below diagram, UW is the angle bisector of ∠TUV
<u>That means,</u>
Given that, and
So, the equation will be......
So, the value of x will be 6.
