Answer:
0.1527
Step-by-step explanation:
Given that a researcher wishes to conduct a study of the color preferences of new car buyers.
Suppose that 50% of this population prefers the color red
15 buyers are randomly selected
Let X be the no of buyers who prefer red.
X has exactly two outcomes red or non red.
Also each buyer is independent of the other
Hence X is binomial with p = 0.5 and n = 15
Required prob =The probability that exactly three-fifths of the buyers would prefer red
= P(X=9)
= 
=
Answer: 1fp = 525 minutes
35fp = 18,375 minutes
<u>Step-by-step explanation:</u>
Solve this using conversions
For 35 fp, multiply 35 fp by 525 minutes per 1 fp = 18,375
Answer:
14130 ft^3
Step-by-step explanation:
The formula for the volume of a cone of radius r and height h is
V = (1/3)*pi*r^2*h.
Here, V = (1/3)(3.14)(15 ft)^2*(60 ft) = 20*3.14*225 ft^3 = 14130 ft^3
What the heck do you mean??????????
Answer:
38 cm
Step-by-step explanation:
The perimeter is the sum of the sides
Starting from the left and going clockwise, then
9 + (10 - 6) + (9 - 2) + 6 + 2 + 10
= 9 + 4 + 7 + 6 + 2 + 10
= 38
