Answer:
Since the p value is higher than the significance level we don't have enough evidence to conclude that the true mean is different from 36.1 MPG (the claim by the manufacturer)
Step-by-step explanation:
Information given
represent the sample mean for the MPG
represent the population deviation
sample size
represent the value to check
represent the significance level for the hypothesis test.
t would represent the statistic
represent the p value
System of hypothesis
We need to conduct a hypothesis in order to check if manufacturer is incorrect, the null and alternative hypothesis are:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing we got:
P value
Since we are conducting a bilateral test we can find the p value like this:
Conclusion
Since the p value is higher than the significance level we don't have enough evidence to conclude that the true mean is different from 36.1 MPG (the claim by the manufacturer)
10/12 in simplest form is 5/6 because the numerator and denominator can be divided by 2. Your result is 5/6.
Have a great day!
If there are such numbers, then they can be written as 'x', (x + 2), (x + 4), and (x + 6).
Now, the problem says that x(x+2) + 64 = (x+4) (x+6)
Expand each side:
x² + 2x + 64 = x² + 10x + 24
Subtract (x² + 24) from each side:
2x + 40 = 10x
Subtract 2x from each side:
40 = 8x
Divide each side by 8 :
x = 5
The numbers are <u>5, 7, 9, and 11</u>.
(5 x 7) + 64 = 35 + 64 = 99 and 9 x 11 = 99 . yay !
Answer:
y = 4/5x - 3
Step-by-step explanation:
The slope-intercept form of a line is y = mx + b. We need to isolate the y.
(add 4x to 15)
-4x + 5y = 15
5y = 4x + 15
(divide by 5 from both sides)
y = 4/5x + 15/5
y = 4/5x + 3
2499.9999999... is your answer
hope this helps
