3/11 = 33/x
cross multiply
3x = 11 * 33
3x = 363
x = 363/3
x = 121 <===Snane's money
121 + 33 = 154 <== together they have $ 154
Vertical asymptote is x=0
Horizontal asymptote is y= 3
No Oblique Asymptotes
Answer:
a. 5 sets of tires
b. 16 times
Step-by-step explanation:
total distance commuted by the truck = 160,000 miles
a.tires of the truck are changed after every 40,000 miles
40,000 to 80,000 to 120,000 to 160,000 he will change his tires four times assuming he started his journey with the new tires. so, he needs uses a total of 5 sets of tires for the whole journey.
b. changes oil every 10,000 miles then to travel 160,000 miles
=
= 16 times in whole journey
Answer:
And we are confident that the true mean for this case is given by
Step-by-step explanation:
Data given
represent the sample mean for the WBC
population mean
s=3.9265 represent the sample standard deviation
n=187 represent the sample size
Confidence interval
The confidence interval for the true mean is given by:
[tex]\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}[/tex] (1)
The degrees of freedom, are given by:
The Confidence level is 0.90 or 90%, the significance is and , the critical value for this case would be
Replacng into the formula we got:
And we are confident that the true mean for this case is given by
