Answer:
We are given the below frequency table:
Time (sec) Frequency
60 to 119 8
120 to 179 25
180 to 239 14
240 to 299 2
300 to 359 6
Total 55
Therefore, there are 55 individuals included in the summary.
Is it possible to identify the exact values of all of the original service times?
No, it is possible to identify the exact values of all of the original service times because the data values in each class could take on any value between the class limits,
(y - 2) = (5/3)(x - 7) Is horizontal and contains.
I'm not sure that's the answer but I hope it helps you with something!!
Boxers = b
Spaniels = s
Now you have two equations - one that tells you the number of boxers in relation to spaniels and one telling you the number of each breed in relation to the total number of dogs. Solve using substitution.
There are
6 spaniels.
This is because Andrea converted the Percentage wrong.
to Convert a Percent to a Decimal, she should have divided by 100
so 5 divided by 100 = 0.05 [not 0.5]
Andrea should have multiplied 300 by 0.05 instead to get the right answer
quickly finding 10% of a number means to simply move the decimal to the left one place
so 10% of 300 is 30
since 5% is half of 10%
half of 30 is 15
and so 5% of 300 is 15
Hi the answer to your question is
((3y - 3.5) / (3y + 6)) * 25.5 = (17
/ 25.5) * 25.5
((3y - 3.5) / (3y + 6)) * 25.5 = 17
(76.5y - 89.25) / (3y + 6) = 17
((76.5y - 89.25) / (3y + 6)) * (3y +
6) = 17 * (3y + 6) 76.5y - 89.25 = 51y + 102 76.5y - 51y = 102 + 89.25
25.5y = 191.25
y = 191.25 / 25.5
<span>y = 7.5</span>
