Answer:
![967.6cm^{2} (1 d.p)](https://tex.z-dn.net/?f=967.6cm%5E%7B2%7D%20%20%281%20d.p%29)
Step-by-step explanation:
Total Surface Area of Cylinder = ![2\pi rh+2\pi r^{2}](https://tex.z-dn.net/?f=2%5Cpi%20rh%2B2%5Cpi%20r%5E%7B2%7D)
Given from the question, r = 7 cm and h = 15cm
Lets Substitute r and h into the formula to find the Total Surface Area of the cylinder.
Total Surface Area of Cylinder = ![2\pi (7)(15)+2\pi (7)^{2} \\=210\pi +98\pi \\=308\pi cm^{2} \\=967.6cm^{2} (1 d.p)](https://tex.z-dn.net/?f=2%5Cpi%20%287%29%2815%29%2B2%5Cpi%20%287%29%5E%7B2%7D%20%5C%5C%3D210%5Cpi%20%2B98%5Cpi%20%5C%5C%3D308%5Cpi%20cm%5E%7B2%7D%20%5C%5C%3D967.6cm%5E%7B2%7D%20%20%281%20d.p%29)
Answer:
Step-by-step explanation:
The complete question is given thus:
Suppose that computer literacy among people ages 40 and older is being studied and that the accompanying tables describes the probability distribution for four randomly selected people, where x is the number that are computer literate. Is it unusual to find four computer literates among four randomly selected people?
x P(x)
0 0.16
1 0.25
2 0.36
3 0.15
4 0.08
ANSWER:
The odds that this will occur according to the chart are 0.08, or 8%, so although this is unlikely, it's not terribly unusual.
⇒ NO
So from the following we can say it is not unusual to find four (4) computer literates among four randomly selected people.
ok, so P(1) + P(2) + P(3) + P(4) + P(0) = 0.16+0.25+0.36+0.15+0.08 = 1
Whereas the chance of finding four (4) out of four (4) computer iteration is low when compared to other factors.
