You will have to divide 425 by 4 and then subract that answer from 425 and you should get........ $318.75
Answer:
x= -1 and y =7
Step-by-step explanation:
To solve by elimination, multiply the entire first equation by 2 so that your x terms have the same coefficients.
2*(9x+2y=5) becomes 18x+4y=10.
Now stack and add each like term.
18x+4y=10
-18x-3y=-3
----------------------
0x +y = 7
y=7
Substitute y=7 into one of the original equations and solve for x.
9x +2(7) = 5
9x + 14 = 5
9x = -9
x=-1
Answer:
Option B
Step-by-step explanation:
Since the company that Carrie out the survey after the students also arrived at the same conclusion as the student which is: no evidence that preference for brand A is not 0.5. We can say that she did not make any error which could be a type 1 or 2 error and found that the actual value was 0.5 which is the null hypothesis
Null hypothesis: u = 0.5 for brand A
and thus fails to reject the null hypothesis.
The answer would be -2k -30
