At the beginning of a certain study of a group of persons, 15% were classified as heavy smokers, 30% as light smokers, and 55% as nonsmokers. In the five-year study, it was determined that the death rates of the heavy and light smokers were five and three times that of the nonsmokers, respectively. A randomly selected participant died over the five-year period: calculate the probability that the participant was a nonsmoker.

The surface area is the area of all six sides when the object is a box.

Formula

SA = 2*L*w + 2*L*h + 2*w*h

Givens

L = 6 ft

w= 3 ft

h = 2.5 feet

Substitute and Solution

SA = 2*6*3 + 2*6*2.5 + 2*3*2.5

SA = 36 + 30 + 15

SA = 81

Answer:

the top on the right.

Step-by-step explanation:

Using the Pythagorean theorem which states that;

a²+b²=c²

or

side (1) ²+side (2) ²=hypotenuse²

15²+8²=x²

225+64=x²

289=x²

Take the square root of both sides to get;

x=√289=17

x=17

Step-by-step explanation:

[tex] \longmapsto \: hypotenuse(h) = x \\ \longmapsto \: perpendicular(p) = 15cm \\ \longmapsto \: base(b) = 8cm \\ using \: pythagoras \: theorem \\ \hookrightarrow {h}^{2} = {p}^{2} + {b}^{2} \\\hookrightarrow {x}^{2} = ({15cm}^{2} + ({8cm})^{2} \\ x = \sqrt{225 {cm}^{2} + 64 {cm}^{2} } \\ \hookrightarrow \: x = \sqrt{289 {cm}^{2} } \\ \hookrightarrow \: x = 17cm [/tex]

Answer:

False

Step-by-step explanation:

To calculate the unit price of an item, divide the total number of units by the total price is a "false statement." To calculate the unit price of an item, you have to understand that unit price means price per unit. To find the unit price we divide the total cost by the amount of items we are given in the question.

Example:

Sarah has 12 apples, she paid 20 dollars for all 12 apples, what is the unit price?

[tex]unitp=cost\div quantity[/tex]
[tex]unit=20\div12=1.66666667[/tex]
[tex]=1.66666667[/tex]

Round the answer to the nearest cent:
[tex]1.66666667[/tex]
[tex]6 > 5[/tex]
[tex]=1.67[/tex]

Which means the unit price of the 12 apples is "$1.67."

Answer:

50⁰

Step-by-step explanation:

Since j and k are parallel lines cut by two transversals,

2+3+5=180⁰ (Allied angles)

We are given 2(60⁰) and 5(70⁰)

so,

60⁰+3+70⁰=180⁰

60+70=130

130⁰+3=180⁰

Bring the 130⁰ to the R.H.S

3=180⁰-130⁰

Therefore,

3=50⁰

Explanation

The given equation y = 2x+3 is in the form y = mx+b

Compare the terms to see that 2x matches with mx, so m = 2

The other term matches with b, so b = 3

m is the slope and b is the y intercept, so that's how I got those answers above.

Answer:

x = 9

Step-by-step explanation:

If ABCD is a parallelogram, then 6x = 7x - 9

as the point of intersection of the 2 diagonals is the midpoint of AC

6x = 7x - 9

Subtract 6x from both sides:

⇒ 0 = x - 9

Add 9 to both sides:

⇒ 9 = x

Solution:

We know that:

This means that:

Answer:

E. 4 cm

Step-by-step explanation:

Given:

Scale factor (R) = [tex] \frac{m_{image}}{m_{preimage}} = \frac{1}{3} [/tex]

AB = 12 cm

Required:

Length of A'B'

SOLUTION:

A'B' = length of the image = x cm

AB = length of the preimage = 12 cm

Thus, using the scale factor given, the length can be calculated as shown below:

[tex] \frac{m_{image}}{m_{preimage}} = \frac{x}{AB} = \frac{1}{3} [/tex]

[tex] = \frac{x}{12} = \frac{1}{3} [/tex]

Multiply both sides by 12

[tex] \frac{x}{12}*12 = \frac{1}{3}*12 [/tex]

[tex] x = \frac{12}{3} [/tex]

[tex] x = 4 [/tex]

x = A'B' = 4 cm

Step-by-step explanation:

Vertical angles are just angles formed by intersecting lines, there is no rule that states they must be acute (they can also be right or obtuse)

The option that is False is that Vertical angles are acute angles.

In mathematics, the term congruent means a figure, shape, or angle that has two equal parts, size, and length.

However, vertical angles assume a right angle and they are perpendicular to the straight line which makes them 90°, but we know that acute angles are angles that are less than 90°.

Therefore, we can conclude that vertical angles are not acute angles.
