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

Which of the following graphs shows the solution set to t > 4 or t < -1?

Answers

Answer:

The second graph

Step-by-step explanation:

t is greater than 4 and less than -1 but doesn't include the points 4 and -1 (thus the open circles)

The second graph represents the solution set to t > 4 or t < -1.

What are open and closed interval ?

In open interval we do not include the point and represented by open circle in close interval we do include the points and represented by closed interval.

According to the given question we have to determine which graph represents the solution set t > 4 or t < -1.

We know when we represent less than or greater than in the number line we represent it as an open circle.

So, t > 4 will be represented by an open circle on the number line starting at 4  but not including which goes to positive infinity and t < -1 will be represented by an open circle at -1 not including which goes to negative infinity.

The height of a building is 72 m. Find the angle of elevation from a point on ground level that is 55 m away from the base of the building

Answers

Answer:

52.6 degrees

Step-by-step explanation:

tan^-1(72/55)

Angle of elevation is equals to 52°7'(approximately).

What is angle of elevation?

" Angle of elevation is the angle between the horizontal plane and  line of sight from the point of observation."

Formula used

In a right angled triangle,

tanθ = ( opposite side) / adjacent side)

According to the question,

As shown in diagram

Height of the building (AB) = 72m

Distance between base of the building and point of observation

(BC)= 55m

Angle of elevation = θ

Substitute the value in the formula we have,

 tanθ = AB / BC

          = 72 / 55

⇒ θ = tan⁻¹ (72 /55)

      = tan ⁻¹(1.3091)

      = 52° 7' (approximately)

Hence, angle of elevation is equals to 52°7'(approximately).

Answers

Answer:

5. 34% 6. $190.73

Step-by-step explanation:

trust man just trust

Answer:

5) 52

6) $190.73

Step-by-step explanation:

5)

Let the unknown number be x.

40 is 77% of x

40 = 0.77x

Divide both sides by 0.77

x = 52

Answer: the number is 52.

6)

We first calculate the amount of tax which is 6.875% of $178.46.

6.875% of $178.46 =

= 0.06875 * $178.46

= $12.27

The amount of tax is $12.27.

Now we add the amount of tax to the price before tax.

$178.46 + $12.27 = $190.73

Find the intercepts of the graph given the following equation 4x – 3y = 12

Answers

Answer:

y-intercept: -4 or (0, -4)

x-intercept: 3 or (3, 0)

Step-by-step explanation:

4x - 3y = 12

we can convert this to slope-intercept form (y = mx+b) given that m is the slope and b is the y-intercept

4x - 3y = 12

-3y = -4x + 12

y = 4/3x - 4

So the intercept is -4 or (0, -4).

For the x-intercept, we can make the y value 0 to solve for x.

4x - 3y = 12

4x - 3(0) = 12

4x = 12

x = 3

So the x-intercept is 3 or (3, 0).

We just need to substitute the variables here! You already have the equations so instead of [tex]x[/tex] for hours, we use [tex]h.[/tex] And since it's a function the result is not [tex]y[/tex] but rather [tex]S(h)[/tex].
