Answer:
The mean of depth is 12.75cm.
The variance of depth is of 13.02 cm².
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The mean of the uniform distribution is:
The variance of the uniform distribution is given by:
Uniform distribution on the interval (6.5, 19)
This means that:
So
Mean:
The mean of depth is 12.75cm.
Variance:
The variance of depth is of 13.02 cm².
Answer:
3 * (x-2)
this: * means times
When there isn't a space between a letter/number and a parenthesis, then it means to multiply.
Answer:
A) 18/3 or 6 bracelets
Step-by-step explanation:
If it take 3/2 hours to make 1 bracelet, then it will take 9 hours to make 9/(3/2) bracelets. This means that the number of bracelets Jasmine can make in 9 hours following this proportional relationship is 18/3 or 6 bracelets.
Answer:
Mandy's bag is 60% heavyer than Donna's.
Step-by-step explanation:
When someone's bag is "x%" heavyer then someone else's it's the same as saying that it is "100% + x%" of that value, while if it is lighter it's the same as saying that it is "100% - x%".
Since Mandy's bag is 20% heavier than Kathleen's, then:
Mandy = 1.2*Kathleen
Since Donna's bag is 25% lighter than Kathleen's, then:
Donna = 0.75*Kathleen
Kathleen = Donna/0.75
Then
Mandy = 1.2*(Donna/0.75) = 1.6*Donna
A regular octagaon has 8 equal sides
so it only makes sense to say that the other side of an octagon would be 4 inches too!
But if you want to know the total length, multiply 8 x 4 = 32 inches!
BUT THIS IS ONLY IF ITS A REGULAR OCTAGON
otherwise it can't be really determined since I don't know its symmetry or the angles!!
Hope I answered your question! :)
