Answer:
b
Step-by-step explanation:
The conditional relative frequency that the student rides the bus, given that the student is in middle school will be 0.15.
<h3>How to find the relative frequency?</h3>
Relative frequency is the ratio of the considered sub-groups counts to the total count. (so its frequency of the considered sub-group relative to the total frequency).
Students were asked how they traveled to school.
The two-way relative frequency table shows the results.
Then the conditional relative frequency that the student rides the bus, given that the student is in middle school will be
→ 0.15

Answer:
(a) 1km
(b)80 fence panels
Step-by-step explanation:
(a) perimeter = 300+300= 600
200+200= + 400
=1000m
1km = 1000m
(b).
1panel = 2.5 m 1× 200÷2.5 = 80
=200m

The polynomial remainder theorem says that the remainder when dividing a polynomial
by a linear divisor
is simply
.
If
, then the remainder upon dividing by
is
You could also verify this by actually computing the quotient and remainder.
