Answer:

Step-by-step explanation:
It's like solving any equation, except we have letters instead of numbers .
k = 3tm + rs {subtract rs from both sides}
k - rs = 3tm {divide both sides by (3m)}
{swap sides}
m≠0
{m must be ≠0 because you cannot divide by 0. There is no t for m=0}
Answer:
200 bars
Step-by-step explanation:
$300 - $50 = the amount of money you still need, $250
250 dollars/$1.25 per bar = 200 bars you need to sell to get 300 dollars
Answer:
The p value would be given by:
For this case since th p value is lower than the significance level of0.05 we have enough evidence to reject the null hypothesis and we can conclude that the true mean for this case is significantly different from 46.7 MPG
Step-by-step explanation:
Information given
represent the mean
represent the population standard deviation
sample size
represent the value to verify
represent the significance level for the hypothesis test.
z would represent the statistic
represent the p value
Hypothesis to test
We want to test if the true mean for this case is 46.7, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
Since we know the population deviation the statistic is given by:
(1)
Replacing we got:
The p value would be given by:
For this case since th p value is lower than the significance level of0.05 we have enough evidence to reject the null hypothesis and we can conclude that the true mean for this case is significantly different from 46.7 MPG
Answer:
Heidi needs to make 9 oranges to make one large orange juice, give me brainliest answer:)
25$ is the flat fee. 50$ is the amount charged per hour. Therefore the equation is C=25+50h where c is the total cost and h is the amount of hours.
C=25+50h
To find the amount of money for 8 hours simply plug in 8 for h and you get 400. Don't forget to add the flat fee of 25. The total cost for 8 hours of service is 425.
To find the amount of money for 10 hours of work, plug in 10 for h and you get 500. Add 25 to 500 and you get 525 for a total of 10 hours of work.
Hope this helped...
