The mean of a population being sampled is 64, and the standard deviation is 6. If the sample size is 50, the standard error of the mean is

Answers

Answer 1

Answer: The standard error of the mean is viewed as the standard deviation of the error in the sample mean in relation to the true mean. It is expressed as the ratio of the sample standard deviation and the square root of the sample size.

SE = s / √n
SE = 6 / √50
SE = 0.85

A cone is placed inside a cylinder. The cone has half the radius of the cylinder, but the height of each figure is the same. The cone is tilted at an angle so its peak touches the edge of the cylinder’s base. What is the volume of the space remaining in the cylinder after the cone is placed inside it?

Answers

The volume of the cylinder is:
Vcy = π r2 h

And using the given conditions that the cone has half the radius of and same height with the cylinder, we have:
Vco = (1/3) π (r/2)2 h
Vco = π r2 h / 12

The volume of the space remaining is the difference between the two volumes. So,
Vs = Vcy - Vco
Vs = π r2 h - π r2 h / 12
Vs = 11 π r2 h / 12

The volume of the space is 11 π r2 h / 12

Find the value of the combination. From a committee consisting of 8 men and 5 women, a subcommittee is formed consisting of 4 men and 3 women. How many different subcommittees are possible? 80

700

1,716

Answers

Out of 8 men, 4 can be selected and lined up in (8 x 7 x 6 x 5) = 1,680 ways.
But within that number, each group of 4 appears in (4 x 3 x 2) = 24 orders.
So there are (1,680 / 24) = 70 different groups of men.

Out of 5 women, 3 can be selected and lined up in (5 x 4 x 3) = 60 ways.
But within that number, each group of 3 appears in (3 x 2) = 6 orders.
So there are (60 / 6) = 10 different groups of women.

Each different group of 70 men can be joined by any of the 10 groups
of women. So the total number of possible subcommittees is (70 x 10) = 700 .

there are a total of 127 cars and trucks on a lot. If there are four more than twice the number of trucks than cars , how many cars and trucks are on the lot ?

Answers

c + t = 127 ;
t = 2c + 4;
then, c + 2c + 4 = 127;
3c = 123;
c = 123 / 3 ;
c = 41 ( cars )
t = 2 * 41 + 4 = 88 ( trucks ).
