<span>Graph the first equation (number of baskets made. You can do this by hand by picking a value for x (number of 2-point baskets) and solving for y. Let’s pick 2 for x.
x = 2, y =
Therefore, the point (2, ) is on the graph.
Let’s pick another value for x to find a second point on the graph. Let x be 4.
x = 4, y =
Therefore, the point (4, ) is on the graph.
Let’s pick one more value for x. Let x be 6.
x = 6, y =
Therefore, the point (6, ) is on the graph. Graph these three points and sketch the line through them.</span>
Mean means average, so add all the ages together and divide by the number of people asked:
19 + 27 + 25 + 21 + 44 + 22 + 45 + 34 = 237
237 / 8 = 29.625 = 30 years
You have to calculate the probability for the given average:
= 3/200 = 0.015 = 1.5%
For 50,000 phones you have to multiply the probability by 50,000:
0.015*50,000 = 750 phone defectives if the company produced 50,000
Answer:
The graph belongs to the conic family called circle. Assign several values for
θ
then compute corresponding
r
then plot the graph
Explanation:
The given
r
=
4
sin
θ
is equivalent to
x

now, you are ready to graph
kindly see the graph below
