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

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
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.

. Write the equation of a line in the graph below.
A. y = 3x - 2
B. y = 3x + 2
C. y = -3x - 2
D. y = -3x + 2
Answer:
D
Step-by-step explanation:
The y intercept is (0,2) so you can eliminate A and C because they have -2 and the slope is negative so you can eliminate B because it has a slope of +3 so you are left with D.

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)
