Answer:
1). 24
2). 8
Explanation:
1).
285$ - 45$ = 240$
240$/10 = 24$
Therefore, he pays 24$ a month.
2).
Let x be the number than triple:
3x - 5 = 19
3x = 19 + 5
3x = 24
x = 24/3
x = 8
It would be 12 x 3. This is because 4 x 3 is 12. He wants to triple the area. Multiply 12 by 3= 36. Hope it helps.
Answer:
So we can find this probability:
And then since the interest is the probability that the mean diameter of the sample shafts would differ from the population mean by more than 0.3 inches using the complement rule we got:
Step-by-step explanation:
Let X the random variable that represent the diamters of interest for this case, and for this case we know the following info
Where and
We can begin finding this probability this probability
For this case they select a sample of n=79>30, so then we have enough evidence to use the central limit theorem and the distirbution for the sample mean can be approximated with:
And the best way to solve this problem is using the normal standard distribution and the z score given by:
And we can find the z scores for each limit and we got:
So we can find this probability:
And then since the interest is the probability that the mean diameter of the sample shafts would differ from the population mean by more than 0.3 inches using the complement rule we got:
B because it’s rounded and it’s clocks wide and just look closely you’ll get it
<h3>Hello There!!</h3>
<u>Solution For Given Question </u>
Three times x is 13 less than y
The sum of x and two times y is 12.
Replacing Value of Y with 3x + 13
Now we need to fine Value of'y' i e.,
