Answer:
The circumference is 16π or 50.2654 depending on whether they ask you for an exact value or in terms of pi.
Step-by-step explanation:
2r=d
2(8)=d
16=d
C=πd
C=π16
So, the circumference is 16π or 50.2654 depending on whether they ask you for an exact value or in terms of pi.
That is 0,3 pounds per hamburger for all 40 hamburgers he will make.at $2.25/ per pound you buy 12 pounds for $27.
12 pounds divided by 40 is 0.3 pounds. That's the weight in pounds of each meat in each hamburger.
6 3/8 YOU CAN WRITE AS 51/8,
7 2/5 YOU CAN WRITE AS 37/5
51/8+ 37/5= (255+296)/40=551/40
551/40= 13 31/40 KG
Answer:
And we can find this probability using the complement rule and with excel or the normal standard table:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the complement rule and with excel or the normal standard table:
