Answer:
Part a)
Mean: 13155.6
Mode:None
Median: 12700
Step-by-step explanation:
12700 : 1
15478: 2
12675: 3
11850: 4
13075: 5
Mean :
Mode:
All values are distinct, therefore there is no mode. A mode is value which occurs most frequently.
Median:
Arrange the values in ascending order:
11850 , 12675, 12700, 12075, 15478
The mid value is median: 12700
Part b)
It depends upon the data. In this question the best way to predict how many miles Gina will drive in the next years is by using Median of the data.
The reason is that there is a potential outlier in the data i.e 15478. In case of outlier median tends to give better predictions.
Multiply 2.25 by each answer and 750 and write down the total next multiply 3.25 by each answer lowest to highest once you get a product that is higher than you writen down answer play around with the numbers until you get the exact amount D 760 2.25 times 760 is 2460 by 3.25 its 2570 you save 10 dalloars and are able to pay for the food and band
Answer:
x+y=4+8=12
$12 for one of each
or if you mean indivually (the wording confused me)
$4 for child, $8 for adult
Step-by-step explanation:
x=adult
y=child
2x+10y=56
4x+5y=52
iin order to be able to subtract values and find x and y im going to multiply 4x+5y=52 by two and get 8x+10y=104
8x+10y=104
-2x+10y=56
6x=48 divide each side by 6
x=8
plug 8 back into an equation to find cost of y
2(8)+10y=56
-16 -16
10y=40
y=4
Answer:
The probability that there will be repair exactly 3 toaster is 0.0574.
Step-by-step explanation:
Binomial Distribution:
A discrete random variable X having the set {0,1,2,3......,n} as the spectrum, is said have a binomial distribution with parameter n= number of trials and p=probability of number of success on an individual trial, if the p.m.f (probability mass function) of X given by,
x=0,1,2,......,n
=0 elsewhere
where 0<p<1 and n is a positive integer.
Total number of toaster in cartons(n) = 10.
Probability of number of success on an individual trial p= 10% = 0.10
=0.0574
The probability that there will be repair exactly 3 toaster is 0.0574.
Answer:
Not enough detail.
Step-by-step explanation:
When asking the question please know which operation you are using to get the number '14,911'. If you were doing multiplication the answer would be 15.5. If it was addition it would be 14848.
Please make sure you ask the question with full detail next time.
