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

HEY CAN ANYONE PLS ANSWER DIS MATH QUESTION!!!!!!!!!!!!
Answer:
A is the answer, i.e at the cost, c of $250.
Step-by-step explanation:
0.08c = 0.05c + 7.5
0.08c - 0.05c = 7.5
0.03c = 7.5
c = 7.5/0.03 = 250
Find the intercepts of the graph given the following equation 4x – 3y = 12
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).

At the park, a statue stands on a marble base. The statue and marble base have a total height of 59.4 inches. The height of the marble base is 16.09 centimeters. Given that 1 inch is equal to 2.54 centimeters, what is the height of the statue?
Answer:
134.786 centimeters
Step-by-step explanation:
First you need to convert inches to cm by doing 59.4x2.54=150.876 then you subtract 16.09 from that. Your answer would be 134.786 centimeters
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
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).

Answer:
X=3,0
Step-by-step explanation:
Tran earns $16 per hour and is paid a flat fee of $46 each week. At
the end of the week her total salary can be represented by the
equation y=16x + 46, where x is the number of hours, and y is the
total weekly salary. Write this relationship in functional notation, as a
function S(h), where S(h) represents the salary for h number of hours.
Answer:
[tex]S(h)=16h+46[/tex]
Step-by-step explanation:
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].
So we get the answer of: [tex]S(h)=16h+46[/tex]

6) in Minnesota sales tax is 6.875%.what is the total (including tax) on items that total $178.46?
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

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