The data set SMOKE.dta contains information on smoking behavior and other variables for a random sample of single adults from the United States. The variable cigs is the (average) number of cigarettes smoked per day. Do you think cigs has a normal distribution in the U.S. adult population? Explain.

Answers

Answer 1

Answer and explanation:

First more than half of the population of the United States do not smoke so the data for smokers in the United States cannot be normally distributed.

Cigs variable does not have a normal distribution in the United States because it is skewed while a Gaussian/normally distributed data is symmetric about it's mean meaning that more values close to the mean occur more frequently. A normally distributed data has more data in the center and is bell shaped while a non normal distribution like the smokers data for US has data skewed to the left or right

Complete Question

The Henderson Hawks minor-league baseball team is giving away baseballs an

game. The balls cost $3 each and the towels cost $2 each. The team wants to give away 200 items and have 500 to spend. How many of each item should the team give away Show your

work or explain your reasoning.

Answer:

They should give away 100 balls and 100 towels

Step-by-step explanation:

Let the number of balls = x

Let the number of towels = y

x + y = 200........ Equation 1

y = 200 - x

$3 × x + $2 × y = $5000

3x + 2y = 5000...... Equation 2

3x + 2(200 - x)= 5000

3x + 400 - 2x = 5000

Collect like terms

3x - 2x = 500 - 400

x = 100

Number of balls to be given away = 100

Note:

y = 200 - x

y = 200 - 100

y = 100

Number of towels to be given away = 100

Therefore, they should give away 100 balls and 100 towels

Answer:

FE = 10.30

ED = 7.62

FD = 7.28

Step-by-step explanation:

First, use coordinate system to draw a square that each angle of triangle reach the sides of the square, then use Pythagoras theory to find the length of the sides(c^2=a^2+b^2)

FE = root(9^2+5^2) = root(106) = 10.30

ED = root(3^2+7^2) = root(58) = 7.62

FD = root(2^2+7^2) = root(53) = 7.28

So we have 2/3 s + 5/6 s
In order to simplify this, we need to get a common denominator and we can do this by multiplying 2/3 by 2, which yields 4/6 s.

Now, we add the two together:
4/6(s) + 5/6(s) = 9/6 (s) = 21

Finally, we can divide 21 by 9/6 which yields 126/9. This simplifies to 14.

The Sum Of Two Numbers Is 18 And Their Difference Is 4

Answers

Answer:

The two numbers are 7 and 11.

[711?  Is this an ad?  ← :)]

Step-by-step explanation:

Let A and B stand for the two numbers.

We are told that:

1)  A+B=18, and

2)  A-B=4

Take the first expression and rearrange to isolate A:

A+B=18

A=18-B

Use this in the second expression:

(18-B)-B=4

-2B = -14

B = 7

From (1) we find A:  

A+B=18

A+7=18

A= 11

If A=11, then B=7 (from A+B=18)

CHECK:

Does A+B=18?

  11 + 7 = 18?  YES

Does A-B=4?

    11 - 7 = 4?  YES

Answers

Answer:

134 degrees

Step-by-step explanation:

the angles in a triangle always add up to 180.

86+48=134

to find the last angle you subtract 180-134

this gives you 46 degrees

a straight line is always measured as 180 degrees.

180-46=134

so x=134 degrees

Jessie read three books in one week. At this rate, how many books will she read in 3 weeks?

Answers

Answer:

Jessie will read 9 books in 3 weeks.

Step-by-step explanation:

3 x 3 = 9

Answer: 9

Step-by-step explanation: If you need an equation, you can create one:

t = total number of books read

w = weeks

t = 3w

The 3 is there because she reads 3 books weekly, so you multiply the number of weeks by the number of books she reads.

Plug in 3 weeks:

t = 3(3)

t = 9 books

Jessie reads 9 books in 3 weeks.
