The answer is 59.99 because if you divide 180 by 21 you will get 8.57..... Then you need to multiply 8.57..... by 7 to get 59.99
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:
<em>x = 3 and y = 0</em>
Step-by-step explanation:
3y+x=3
-2y+5x=15
Isolate y in 3y + x = 3 :
Substitute 
in -2y + 5x = 15 :
Simplify the equation :
Isolate x in 
:
Proving x = 3
Isolate y in 
:
Proving y = 0
Your solved system of equations are x being 3, and y being 0.
Let the number be x.
9(1/4)+x=x/3+6
Simplify.
2.25+x=x/3+6
-6 -6
-3.75+x=x/3
•3 •3
-11.25+3x=x
-3x -3x
-11.26=-2x
5.625=x
