Answer:
Below.
Step-by-step explanation:
Complete the multiplication and the equation becomes
4/6−3/6=?
The two fractions now have like denominators so you can subtract the numerators.
Then:
4−3/6=1/6
This fraction cannot be reduced.
Therefore:
2/3−1/2=16
Solution by Formulas
Apply the fractions formula for subtraction, to
2/3−1/2
and solve
(2×2)−(1×3)3×2
=4−3/6
=1/6
Therefore:
2/3−1/2=1/6

Researchers estimate that 21.5% of men and 17% of women smoke cigarettes.1
The rate of new cases in 2008 showed that men develop lung cancer more often than women (70.2 and 50.5 cases per 100,000 persons, respectively).2
Smoking, a main cause of small cell and non-small cell lung cancer, correlates to 90% and 80% of lung cancer deaths in men and women, respectively.3 That is, 90% of men who are diagnosed with lung cancer are active smokers, and 80% of women who are diagnosed with lung cancer are active smokers.
1. What answer do you predict? Why? (2 points)
2. Given what you know about probability, how can you determine if smoking and lung cancer are related? (2 points)
Analyze the Data:
3. What is the probability that a randomly chosen man is a smoker? (1 point)
4. What is the probability that a randomly chosen man will be diagnosed with lung cancer? (1 point)
5. Given that a man has lung cancer, what is the probability that he is a smoker? Write this event with the correct conditional notation. (2 points)
6. What is the probability that a randomly selected man will be a smoker and be diagnosed with lung cancer? (2 points)
7. For a randomly selected man, are the events diagnosed with lung cancer and smoker independent events? Support your answer with probabilities. (2 points)
Consider the Case for Women:
8. For a randomly selected woman, are the events diagnosed with lung cancer and smoker independent or conditional? Support your answer with probabilities. (4 points)
Making a Decision:
9. What can you conclude about smoking and lung cancer? Are they conditional or independent events? (2 point)
10. Some people who have never smoked develop lung cancer. Does this disprove the evidence? (1 point)
Answer: Given what i know about probability, you can determine if smoking and lung cancer are related by testing a group of smokers and non smokers and finding out the percent of each that develope lung cancer and the percent that dont for both

A number decreased by sixteen, then multiplied by eight is equal to forty-four
Answer:
[tex]\frac{43}{2}[/tex] or 21.5
Step-by-step explanation:
8(x - 16) = 44
8x - 128 = 44
+ 128 + 128
8x = 172
/8 /8
x = [tex]\frac{43}{2}[/tex] = 21.5
To check:
8(x - 16) = 44
8(21.5 - 16) = 44
172 - 128 = 44
44 = 44
This is a true statement, which makes our answer true.

Product of two polynomials can be done by distribution of multiplication over addition. The product of [tex]-2x(x^2 - 3)[/tex] is [tex]-2x^3 + 6x[/tex]
What is distributive property of multiplication over addition?Suppose a, b and c are three numbers. Then we have:
[tex]a(b + c) = a\times b + a\times c[/tex]
(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)
The product result of the given expression is
[tex]-2x(x^2 - 3) = -2x^{1 + 2} + 6x = -2x^3 + 6x[/tex]
It is because when bases are same and there is multiplication, then powers add up, so we have: [tex]a^b \times a^c = a^{b+c}[/tex]
Thus,
The product of [tex]-2x(x^2 - 3)[/tex] is [tex]-2x^3 + 6x[/tex]

Elena's aunt bought her a $150 savings bond when she was born. When Elena is 20 years old, the bond will have earned 105% in interest. How much will the bond be worth when Elena is 20 years old?
The worth of the bond is $307.50.
What is the worth of the bond?The worth of the bond is the sum of the bond when it was bought and the interest earned on the bond.
Worth of the bond = interest rate + value when the bond was bought
Interest = 105% x $150
1.05 x $150 = $157.70
Worth of the bond = $157.70 + $150 = $307.50

The two rectangular prisms are similar. What is the volume of the larger rectangular prism? 240 cm³ 540 cm³ 1620 cm³ 3240 cm³ A smaller rectangular prism with a side length of five centimeters and volume of sixty cubic centimeters. A larger, similar rectangular prism with a side length of fifteen centimeters.
Volume of a figure is measure of the space it occupies. The volume of the larger rectangular prism is given as: Option C: 1620 cm³
If a rectangular prism has dimensions a unit, b unit, and c units, then its volume is given as
[tex]V = a \times b \times c \: \rm unit^3[/tex]
What are similar figures?They are scaled. It means, if two figures are similar, then we can get one figure from another by multiplying some constant value(same for one pair of similar figure) to its dimensions.
For example,
if for given case, one rectangular prism has got dimensions a, b, and c centimetres, then
the second rectangular prism, which is similar, let the scale factor is 'd',t then second prism's dimensions will be a x d units, b x d units, and c x d units.
For first prism(smaller), its one side is given to be 5 cm, let its other two sides be 'b' cm, and 'c' cm, then,
[tex]60 \: \rm cm^3 = 5\times b\times c \\\\b\times c = \dfrac{60}{5} = 12[/tex]
Now, the larger prism has 15 cm corresponding side, thus, scale factor was 3 (since 15 is 3 times 5).
Thus, its dimensions would be 15, 3 x b, 3 x c
Thus, its volume would be
[tex]15 \times 3 \times b \times 3 \times c = 135 \times b\times c = 135 \times 12 = 1620 \: \rm cm^3[/tex]
Thus,
The volume of the larger rectangular prism is given as: Option C: 1620 cm³

Angle at A = 65°
Angle at B = 40°
According to the porperty of triangle we know that total interior angle a triangle has is 180° irrespect of type or size
A + B + C = 180

A town is designing a rectangular park that will be 600 feet wide by 1000 feet long. On a scale drawing, the dimensions of the park are 12 inches wide by 20 inches long. A rectangular area of the park for swing sets is 0.5 inches wide by 2 inches long on the scale drawing.
What is the actual length of the swing set area of the park?
Enter your answer in the box.
The actual length of the swing set area of the park is [blank]
feet.
Answer:
The dimensions of the park on the scale drawing are 12 inches by 20 inches
The actual dimensions are given as:
Park = 600 feet by 1000 feet
Swing set = 25 feet by 100 feet
The dimension of the swing set on the scale drawing is given as: 0.5 inch by 2 inches
The above means that, the scale factor (k) is:
--- i.e. divide the scale measurement by the actual measurement
Evaluate both equations
So, we have:
Multiply the scale factor by the dimensions of the park, to get the scale measurement
Hence, the dimensions of the park on the scale drawing are 12 inches by 20 inches

Plot and connect the points A (4, 2), B (-3, 2), C(-3, 5), D (4, 5), and find the length of AB.
Someone please help me:( i need the length of AB and theres no plot diagrammmm
Answer:
AB = 7
Step-by-step explanation:
The y-coordinate of point A and B is the same.
Therefore, both points lie on the same horizontal line (y = 2).
So determine the distance between them, subtract the x-coordinate of B from the x-coordinate of A:
AB = 4 - -3 = 4 + 3 = 7
However, to calculate the distance between 2 points, regardless if the points are on a horizontal (or vertical) line, you can always use the distance between 2 points formula that is derived from Pythagoras' Theorem, as follows:
let [tex](x_1,y_1)[/tex] = point A (4, 2)
let [tex](x_2,y_2)[/tex] = point B (-3, 2)
using the distance between two points equation:
[tex]AB=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]\implies AB=\sqrt{(-3-4)^2+(2-2)^2}[/tex]
[tex]\implies AB=\sqrt{(-7)^2+(0)^2}[/tex]
[tex]\implies AB=\sqrt{49}[/tex]
[tex]\implies AB=7[/tex]

Write the point slope form of the equation of the line through the given point and slope
Step-by-step explanation:
the point-slope form in general is
y - y1 = m(x - x1)
where (x1, y1) are the coordinates of a point, and m is the slope.
so, we have
y - -1 = 4/3 × (x - 3)
or simplified
y + 1 = 4/3 × (x - 3)
Answer:
[tex]y + 1 =\frac{4}{3} (x-3)[/tex]
Step-by-step explanation:
Pre-SolvingWe are given that a line contains the point (3, -1), and has a slope of [tex]\frac{4}{3}[/tex].
We want to write the equation of this line in point-slope form.
Point-slope form is given as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1 ,y_1)[/tex] is a point.
SolvingSince we are already given the slope and the point of the line, we can plug these values into the formula to get the equation.
Let's start with the slope; replace m with [tex]\frac{4}{3}[/tex] in the formula.
[tex]y-y_1=\frac{4}{3}(x-x_1)[/tex]
Now, replace 3 as [tex]x_1[/tex] and -1 as [tex]y_1[/tex]. Remember that the formula has subtraction in it.
[tex]y--1=\frac{4}{3} (x-3)[/tex]
This can be simplified to become:
[tex]y + 1 =\frac{4}{3} (x-3)[/tex]
