In other words, what is the largest number (integer) that will divide evenly into both 24 and 45? Try 3: 3{8,15}. Stop here, since 8 and 15 have no common factor other than 1.
Cool question relying on real life scinarios
A.
1 loaf=inital cost for macine+cost per bread or
number of loaves=x
cost to make=y
y=100+0.8x
so to find 1 loaf, just subsitute 1 for x
y=100+.8(1)
y=100+0.8
y=100.80
1 loaf costs $100.80 to make
B.
start up cost is $100
C. linear equation is
start up cost+cost per loaf times loaf or
y=100+0.8x
in y=mx+b form
y=0.8x+100
C.
to find points, just subsitute values for x and get values for y (I used multiplules of 10 so that you wouldn't have to plot a decimal coordinate)
if we put it 0 for x, we get 100 for y
if we put in 10 for x, we get 108 for y
if we put in 20 for x, we get 116 for y
and of course don't use negative becasue you can't make negative amounts of bread
There are 60 minutes in 1 hour
and 186 divided by 60 = 3 remainder 6
which means you have 3 hours and 6 minutes
that will get you the mixed fraction of
3 6/60 which can be simplified to
3 1/10
Answer:
The 98 percent confidence interval for the population mean is between 27.85 and 29.75 subjects.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the mean subtracted by M. So it is 28.8 - 0.9488 = 27.85 subjects.
The upper end of the interval is the mean added to M. So it is 28.8 + 0.9488 = 29.75 subjects.
The 98 percent confidence interval for the population mean is between 27.85 and 29.75 subjects.
