Yes, because $45 is 60% of $75. So with $80 she has more than enough for the bike.
Answer:
64 photographs
Step-by-step explanation:
432 ÷ 92 = 4.695
Since the whole number in the answer is 4, multiply it with 92.
92 x 4 = 368
After that, minus it with all the photographs he have.
432 - 368 = 64
(Final answer)
That is how much photographs have to be partially filled.
The lower quartile is the mean of the lower half of the data set, not incuding the median value. In this case, the lower half is 5, 8, 10, 20 and the median is 9.
Split up the integration interval into 4 subintervals:
The left and right endpoints of the -th subinterval, respectively, are
for , and the respective midpoints are
We approximate the (signed) area under the curve over each subinterval by
so that
We approximate the area for each subinterval by
so that
We first interpolate the integrand over each subinterval by a quadratic polynomial , where
so that
It so happens that the integral of reduces nicely to the form you're probably more familiar with,
Then the integral is approximately
Compare these to the actual value of the integral, 3. I've included plots of the approximations below.
