Answer:
Step-by-step explanation:
the statement 0 < t < 52.5 represents all the time values for when Riko is behind Yuto, she catches up to Yuto at 52.5 minutes into her ride. Her ride starts at time of zero , so she can't have a negative time, like -4 because she isn't involved in the activity of riding her bike.
3.6 customers x customers
-------------------- = ----------------
.5 hours 7.5 hours
using cross products
3.6 * 7.5 = x * .5
divide by .5 on each side
3.6 * 7.5 / .5 =x
54 =x
You can help 54 customers
<span>To minimize the perimeter you should always have a square.
sqrt(289) = 17
The dimensions should be 17 X 17
To see , try starting at length 1, and gradually increase the length.
The height decreases at a faster rate than the length increases, up until you reach a square.
Or if you want to use algebra, Say the width is 17-x
Then the length is 289/(17-x)
Now, this is bigger than 17+x, as shown here:
289/(17-x) > 17+x
289 > 289 - x^2
which is true.
so the perimeter would be bigger than 2 * (17- x + 17 + x) = 2 * (2 * 17) = 4 * 17
Again, the dimensions should be a square. 17 X 17.</span>
Y = 12x - 40
the x variable represents the number of hours Sam works at the airport
the y value represents the amount in dollars that Sam has after paying Daniel
the 12 is the amount in dollars that Sam earns per hr
the 40 is the amount in dollars Sam owes Daniel
The number of people who voted follows a binomial distribution with probability of having voted
and
subjects, which means the approximating normal distribution should have mean
and standard deviation
.
With the continuity correction, you have
