Step-by-step explanation:
Some researchers claim there is an association between taking vitamins and gaining weight. They took a random sample of people living in Boston, Massachusetts, and recorded whether they took vitamins and whether they gained weight. The results are shown in the following two-way table:
Has Gained Weight Has Not Gained Weight
Does not take vitamins 52 19
Takes one vitamin per day 35 49
Takes more than one vitamin per day 72 80
If a person is chosen at random, what is the probability that he or she has gained weight, given that he or she takes more than one vitamin per day?
0.42
0.45
0.47
0.50
Answer:
The probability that he or she has gained weight, given that he or she takes more than one vitamin per day is 0.47
Step-by-step explanation:
Has Gained Weight Has Not Gained Weight
Does not take vitamins 52 19
Takes one vitamin per day 35 49
Takes more than one vitamin per day 72 80
We are supposed to find the probability that he or she has gained weight, given that he or she takes more than one vitamin per day
A= he or she has gained weight
B=he or she takes more than one vitamin per day
[tex]P(A|B)=\frac{P(A \cap B)}{P(B)}[/tex]
[tex]A \cap B = 72[/tex]
B = 72+80=152
So,[tex]P(A|B)=\frac{72}{152}=0.47[/tex]
So, Option C is true
Hence the probability that he or she has gained weight, given that he or she takes more than one vitamin per day is 0.47

Answer:
31.4 cm
62.8 cm
Step-by-step explanation:
The radius of the inner circle is 5 cm. The line from the edge of the outer circle to the edge of the inner circle is 5 cm. Assuming that the center of the outer center is the same as the center of the inner circle, the radius of the outer should be 10 cm.
Use the formula for circumference since you have the radius.
Inner circle
C = 2πr
C = 2π(5)
C = 10π
C = 31.4 cm
Outer Circle
C = 2πr
C = 2π(10)
C = 20π
C = 62.8 cm

What is the slope of a line parallel to the line whose equation is x+y=5 Fully reduce your answer.
Slopes of Parallel/Perpendicular Lines
Answer:
-1
Step-by-step explanation:
y=-x+5
Parallel lines have same slopes.
The slope of the parallel and perpendicular lines will be -1 and 1, respectively.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The equation of the line is given below.
x + y = 5
y = -x + 5
The slope of the equation is a negative one.
The slope of the parallel lines will be the same which is negative 1.
The slope of the perpendicular lines will be the negative inverse of the slope that is 1.

It takes 323232 minutes for 888 people to paint 888 walls.
How many minutes does it take 121212 people to paint 121212 walls?
minutes
Answer:
323232÷121212
answer=2.66
Answer:
32 minutes
Step-by-step explanation:
Imagine that each person is assigned one wall, and all 8 people begin painting at the same time.
Since everyone will finish painting their assigned wall after 32 minutes, it takes one person 32 minutes to paint one wall.
If we have 12 people and 12 walls, we can again assign one wall to each person.
Everyone will take 32 minutes to paint their assigned wall.
In other words, it takes 32 minutes for 12 people to paint 12 walls.

Both lines have a negative slope and The slope of the line in the graph is -2
The equation of a straight line is given by:
y = mx + b;
where m is the slope of the line, b is the y intercept, y,x are variables.
Given that a line goes through (-2, 1) and (0, -3), the equation of this line is given by:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-1=\frac{-3-1}{0-(-2)} (x-(-2))\\\\y-1=-2(x+2)\\\\y-1=-2x-4\\\\y=-2x-3[/tex]
Therefore the slope of the line in the graph is -2
The second line is given by:
[tex]y=-\frac{2}{9} x+2[/tex]
This line has a slope of -2/9
a) Both lines have a negative slope
b) The graph has a steeper slope

Answer:
4a ) Difference ⇒ $ 63.24,
4b ) 4 children
Step-by-step explanation:
4a ) If the number of children is represented by the value of x, let us substitute a family of 2 children as value of x into this equation we are given;
y = 21.08 * ( 2 ) + 85.15 ⇒ Multiply 21.08 by 2,
y = 42.16 + 85.15 ⇒ Combine like terms,
y = 127.31
If y ⇒ amount spent on grocery's, let us solve for the amount spent on 5 children, and subtract from this amount;
y = 21.08 * ( 5 ) + 85.15 ⇒ Multiply 21.08 by 5,
y = 105.4 + 85.15 ⇒ Combine like terms,
y = 190.55
Difference; 190.55 - 127.31 = 63.24,
Solution; Difference ⇒ $ 63.24
4b ) If the amount is $ 169.47, let us plug it into our given equation provided amount spent on groceries ⇒ y;
169.47 = 21.08x + 85.15 ⇒ Subtract 85.15 from either side of equation,
21.08x = 84.32 ⇒ Divide either side 21.08,
x = 4 children
Solution; 4 children

Which equation can be used to find the surface area of the cylinder?
r= 6 cm
h = 8 cm
S= 28(8)2 +2 (12)(6)
O S=2(6)? +2(6)(8) *
O S=212)2 + 23412)(8)
S = 2846)2 +27(6)(8)
Answer:
S = 2π(36) + 2π(6)(8)
S = 2(3.14)(36) + 2(3.14)(6)(8)
Step-by-step explanation:
The surface area of a cylinder is the sum of the area of the base and the lateral area. A cylinder has 2 circular base .
Surface area = 2πr² + 2πrh
surface area = 2πr(r + h)
where
r = radius
h = height
surface area = 2πr(r + h)
r = 6 cm
h = 8 cm
The equation to find the surface area is represented below.
Surface area = 2πr² + 2πrh
S = 2π (6²) + 2π (6)(8)
S = 2π(36) + 2π (6)(8)
Assuming π is given as 3.14 the equation will be as follows
S = 2(3.14)(36) + 2(3.14)(6)(8)

Omar has a gift card with a $150 balance he buys several video games that cost $35 each after the purchase has his gift card balance is $45
Answer:
3
Step-by-step explanation:
150-35=115
115-35=80
80-35=45
Answer:
Omar bought 3 games? (You didn't ask a question but this is what I assumed)
Step-by-step explanation:
Use this equation to find out how many games (x) Omar bought with $45 left over.
45 = 150 - 35x
Combine like terms and put them on opposite sides of the equal sign.
-105 = -35x
Divide both side by -35
3 = x, so x = 3
Omar bought 3 video games

x + 2y = 3 ( subtract x from both sides )
2y = - x + 3 ( divide all terms by 2 )
y = - [tex]\frac{1}{2}[/tex] x + [tex]\frac{3}{2}[/tex] ← in slope- intercept form
with slope m = - [tex]\frac{1}{2}[/tex]
(b)
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{2} }[/tex] = 2
(c)
The partial equation of the perpendicular line is
y = 2x + b
To find b substitute (1, 4) into the partial equation
4 = 2 + b ⇒ b = 4 - 2 = 2
y = 2x + 2 ← equation of perpendicular line
