Answer:
your answer is 6 hours
Step-by-step explanation:
you have the 2nd pipe takes 72 hours so then you multiply 4 x 9 x 12 which is 432 and then you divide 432 by 72 which is 6 so it would be 6 hours
hope it helps ^^
Answer:
Step-by-step explanation:
When we collect a large data we may find a single entry repeated. In these cases we prepare frequency distribution with x = the item in one column and f = the no of times it repeats i.e. frequency in other column.
Similarly for class intervals also, we write as frequency to the right side of interval column which gives no of items which fall within the class.
This process ensures compact presenting of data.
Hence we have
a)The number of observations that fall in a class
answer: Frequency
b) The relative frequency of a class multiplied by 100
answer: Percentage. Because when we express probability as a percentage we get total 100
c) The ratio of the frequency of a class to the total number of observations
answer: Relative frequency
(Relative frequency also known as probability is frequency/total entries)
Answer:
124
Step-by-step explanation:
When x=4, substitute 4 into the function to give f(4).
You can subtract 9 from the 713 value and trace until you get a multiple of 7 or vice versa.
It could be one of :
80 figilbuttons and 7 rybirens
or
14 rybirens and 73 figilbuttons
-x + 5y = 8
multiply this equation by 3
-3x + 15y = 24
now add it to the other equation ( elimination)
-3x + 15y = 24
3x + 7y = -2
-----------------------
0x + 22 y = 22
divide each side by 22
y =1
substitute into -x + 5y =8 to find x
-x + 5(1) = 8
-x + 5 = 8
-x =3
divide by -1
x =-3
Answer (-3,1)
