40 and 21 do not have common factors, except for one. So the answer is 1.
For the "system" to function, we require that
occurs (i.e. the event that either
or
function properly). This occurs with probability
but since
and
are independent,
We're given that
and
, so
If
, then
You would have more than $102.
Earning 2% a year in interest would get you $2 in interest the very first year:
100(0.02) = 2
Adding this to the amount in the account, you would have 100+2 = 102 after the first year.
5 in, area is width x length, If the width is 7, the total (35) divided by 7, would get your length.
Answer:
y = 1/2x + 3
Step-by-step explanation:
Y= mx+b is slope-intercept form, m is for slope, and b is for my y-intercept. Also remember the pitch is the rise over the run or the y-direction over the x-direction.
In our case, they highlight 2 points to calculate the slope; looking at the graph, we can see it rises one and runs two to get to the second highlighted point at (2,4). And my slope is rise over run, so here it 1/2.
My b or y-intercept is simply three because that is where the line passes over or intercepts the Y-axis
