Answer:
Huan receives 3.33 pounds (£) every week
Step-by-step explanation:
We can calculate this by dividing the amount for 5 weeks and dividing by 5 to find the amount of pocket money for each week. 16.65/5 = 3.33, which means that he receives 3.33 pounds (£) every week for pocket money.
I think that you round to 9.80 seconds. Pardon me, I didn't understand the problem well
Answer:
Any legal fraction (denominator not equal to zero) with a numerator equal to zero has an overall value of zero. all have a fraction value of zero because the numerators are equal to zero
Step-by-step explanation:
Answer:
Step-by-step explanation:
the ratio is 5:3:2
therefore, Ali receives 5x, Ben receives 3x and Carl receives 2x
Ben receives 60 $
so,
3x = 60
x = 60/3 = 20
Ali's share = 5x = 5*20
Ben's share = 60$
Carl's share = 2x = 2*20
therefore, Ali receives 100$, Ben receives 60$ and Carl receives 40$
so, the total money shared is 60$ + 40$ + 100$ = 200$
<h2>
Answer with explanation:</h2>
Confidence interval for mean, when population standard deviation is unknown:
, where 
= sample mean
n= sample size
s= sample standard deviation
= Critical t-value for n-1 degrees of freedom
We assume the population has a normal distribution.
Given, n= 19 , s= 3.8 , 
A) Critical t value for 
and degree of 18 freedom
= 2.8784
B) Required confidence interval:
Lower bound = 19.9 years
Uppen bound = 24.9 years
C) Interpretation: We are 99% confident that the true population mean of lies in (19.9, 24.9) .
