Answer:
11/15
Step-by-step explanation:
If 4 out of 15 are Canadian, the ratio of the probability of picking a Canadian is 4/15. That means that the probability of NOT picking a Canadian is the complement of 4/15 which is 11/15. Therefore, the probability of not picking a Canadian is the same thing as the probability of picking an American penny which is 11/15.
Answer:
Respondents
Step-by-step explanation:
The customers that buy a new computer and receive a survey in the mail about the performance of the computer after one month are called respondents.
They are called respondents because they took part in a survey or poll about the performance of the computer they bought a month ago. Statistically, not everyone that got the mail took part in the poll, those ones are called non respondents, while the ones that took part in the survey are known as respondents.

Step-by-step explanation:
23 - (2 + 4) - 15/3
23 - (6) - 5
23 - 6 - 5

Answer:
1526.04
Step-by-step explanation:
the formula for calculating the volume of cone is
V=πr^2(h/3)
Thus,
V = (3.14)(9)^2(18/3)
V = (3.14)(81)(6)
V = 1536.04 yd^3
Rounding off to the nearest tenth, we get
V = 1536 yd^3
Speed of tsunami = sqrt (9.8d) m/s where d is the depth of the ocean.
Given speed of tsunami to be 320 m/s, depth of the ocean is calculated as follows:
320=sqrt (9.8d) => 320^2 = 9.8d => d= (320^2)/9.8 = 10448.98 m
To nearest meter, d=10449 m
