Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Total money needed= $5,000

Percentage raised= 75%

To calculate the amount collected and the difference required, we need to use the following formulas:

Total collected= 5,000*0.75

Total collected= $3,750

Difference= 5,000 - 3,750

Difference= $1,250

Answer:

n(U)=30

n(H)=15

n(G)=18

n(H ∪ G)'=5

n(H ∪ G)=n(U)-n(H ∪ G)'

             =30-5=25

So ,n(H ∩ G)=n(H)+n(G)-n(H ∪ G)

                    =15+18-25=8

Therefore, 8 students take both subjects.

A set is a mathematical model for a collection of diverse things. The total number of students who who take both History and Geography is 8.

A set is a mathematical model for a collection of diverse things; it comprises elements or members, which can be any mathematical object: numbers, symbols, points in space, lines, other geometrical structures, variables, or even other sets.

Given that there are 30 students in a class. of those, 15 take history, 18 take geography, and 5 take neither of these subjects. Therefore, we can write the following values,

Now, the number of students who take at least one of the two subject can be written as,

Students who choose at least one subject

= Total students - Students who take neither of the subject

n(H ∪ G) = n(U) - n(H ∪ G)'

n(H ∪ G) = 30 - 5

              =25

Further, the total number of students who who take both the subjects can be written as,

Students who take both the subjects = Students who take History + Students who take Geography - Students who choose at least one subject

n(H ∩ G) = n(H) + n(G) - n(H ∪ G)

n(H ∩ G) = 15 + 18 - 25

n(H ∩ G) = 8

Hence, the total number of students who who take both History and Geography is 8.

Answer: [tex]56,900\left( 0.919\right)^x[/tex]

Step-by-step explanation:

Given

Marcos purchased a sailboat for [tex]\$56,900[/tex]

Each year the boat will decrease in value by [tex]8.1\%[/tex]

After 1 year it is

[tex]\Rightarrow 56,900-56,900\times 0.081\\\Rightarrow 56,900\left( 1-0.081\right)\\[/tex]

after another year it becomes

[tex]\Rightarrow 56,900\left( 1-0.081\right)-56,900\left( 1-0.081\right)\times 0.081\\\Rightarrow 56,900\left( 1-0.081\right)\cdot \left( 1-0.081\right)\\\Rightarrow 56,900\left( 1-0.081\right)^2[/tex]

After [tex]x[/tex] years it is

[tex]\Rightarrow 56,900\left( 1-0.081\right)^x[/tex]

[tex]\Rightarrow 56,900\left( 0.919\right)^x[/tex]

Answer: (x - 5)^2 + (y - 7)^2 = 50

Step-by-step explanation:

The general equation for a circle is (x - a)^2 + (y - b)^2 = r^2 where (a, b) is the centre

Use Pythagoras to find r^2

r^2 = (5 - -2)^2 + (7 - 8)^2

= 7^2 + (-1)^2

= 50

So the circle is (x - 5)^2 + (y - 7)^2 = 50

Answer: [tex]8x^3y[/tex]

Step-by-step explanation:

Given

The area of a rectangle is [tex]24x^5y^7[/tex]

The length of the rectangle is [tex]3x^2y^6[/tex]

The area is given by the product of length and width

Suppose, w is the width of the area

[tex]\therefore A=l\times w\\\Rightarrow 24x^5y^7=3x^2y^6\times w\\\\\Rightarrow w=\dfrac{24x^5y^7}{3x^2y^6}\\\\\Rightarrow w=8x^3y[/tex]

Thus, the width of the rectangle is [tex]8x^3y[/tex]

Answer:

9a = 11a - 2a

9a = 9a

Step-by-step explanation:

9a = 11a - 2a

11 - 2 = 9

Similarly, 11a - 2a = 9a

Eleven minus two equals nine. Similarly, 11a minus 2a equals 9a. You can subtract them because they both have the same variable a.

Answer:

42.7%

Step-by-step explanation:

Correlation is a statistical measure of inter relationship between two variables' co movement.

Correlation coefficient denotes the direction & extent by which two variables' (same or opposite) movement is linked to each other.

Coefficient of determination = r^2 symbolises percentage of variation in one variable, that can be explained by variation in other variable.

So, in this case r^2 = (0.654)^2 = 0.427716 ; Hence approx 42.7% variation in one variable can be explained by variation in other.
