There are 45 possible choices for the five members.

There are ten people on the debate team, but only two of them can be in position 5. Positions 1 through 4 can be filled by any 10 members. Using the combination formula nCr, where n is the total number of items and r is the number of items chosen from that set, we can determine the number of ways to select these five members.

In this instance, we have 10C2, which simplifies to 10!/(2!(10-2)!)) or 10 items chosen from a set of 10. This can be reduced to 45, or 109/2. As a result, there are 45 ways to select the five debate team members.

Tthe population of the colony after 2 hours is 64a

From the question, we have the following parameters that can be used in our computation:

Rate = doubles every 20 minutes

Represent the initial population with a

So, we have the following representation

f(t) = a(2)^t

Where t is the number of 20 minutes in the time

The time is given as 2 hours

So, we have

t = 2 hours/20 minutes

Evaluate

t = 6

The function becomes

f(t) = a(2)^6

Evaluate

f(t) = 64a

hence, the population is 64a

There were 27 commercials during the shows. The unit rate of commercials per hour must be determined. As a result, the hourly unit rate is 18 commercials. And it is determined by Division.

A division is the process of dividing a given amount into equal parts.

Wendy spent one and a half hours on Saturday morning watching her favourite shows on television.

There were 27 commercials during the shows.

The unit rate of commercials per hour must be determined.

To find this we have to devide 27 by number of hours I.ei.e [tex]\frac{27}{1\frac{1}{2} }[/tex]

Convert [tex]1\frac{1}{2}[/tex] to improper fraction= [tex]\frac{27}{\frac{3}{2} }[/tex].

When a whole number is devided by fraction, the denominator is multiplied with the whole number= [tex]27*\frac{2}{3} =\frac{54}{3} =18.[/tex]

60 engineering students are divided into 24 who take math and 29 who take physics. 10 students take statistics and physics together, 13 students take math and physics together. a) There are 26 students take statistics. b) P(A/B)=4/13.

The science of statistics is concerned with the research and advancement of methods for collecting, analyzing, interpreting, and presenting empirical data. The science of learning from data is called statistics, which is also possibly an art. The discipline's focus is on the gathering, analyzing, and interpretation of data as well as the efficient dissemination and presentation of findings that rely on data.

We can assume the following:

1). There are 13-8=5 pupils who study physics and math together but not statistics (green colour)

2). There are 10-8=2 pupils who study physics and statistics together but not math (grey colour)

3). Students who take algebra and statistics but not physics total 11-8=3. (yellow colour)

4). There are 14 pupils (29-5-8-2) who only take physics (pink colour)

We can now determine how many students solely take statistics by doing the following: The number of students enrolled in at least one course (60–7) less the number taking only math or just physics or just statistics but not math.

53-24-14-2=13 students take only statistics

There are 26 students who take statistics, or 13 + 2 + 3 + 8

b) Let's say A takes all three, and B takes statistics. Finding conditional probability is the goal.

P(A/B)= P(A⋂B)/P(B)

P(A⋂B)= 8/60, P(B)=26/60

So,

P(A/B)=P(A⋂B)/P(B)=8/26=4/13

The equation for the Bowler world is c = $1.1g + $5,

The equation for the Lucky spares is c = $1.5g + $3.

and the cost is the same for 5 games and the cost is $10.5.

Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.

Both linear equations with one variable and those with two variables exist.

Given the Bowler, World charges $5.00 to rent shoes and $1.10 per game. Lucky Spares charges $3.00 for shoes and $1.50 per game.

Part A

using g for the number of games and c for the cost

for Bowler World

charges for shoes = $5

cost for per game = $1.1

cost for g games = $1.1g

total cost c =  $1.1g + $5 ..........(1)

for Lucky spares

charges for shoes = $3

cost for per game = $1.5

cost for g games = $1.5g

total cost c =  $1.5g + $3 ..........(2)

B. if the cost used in both places is equal then equation 1 equals equation 2

so $1.1g + $5 = $1.5g + $3

1.5g - 1.1g = 5 - 3

0.4g = 2

g = 2/0.4

g = 5

and cost is c =  $1.1g + $5

c = 1.1*5  + 5

c = 5.5 + 5

c = $10.5

Hence equations are  c =  $1.1g + $5 and  c =  $1.5g + $3,

and the cost is same for 5 games and the cost is $10.5.

The cubic expression of (1 + i) is given as follows:

(1 + i)³ = 0.

The cubic expression is obtained elevating the binomial (1 + i) to the third power, as follows:

(1 + i)³.

Then we expand the expression, applying the rule for the cube of a binomial, hence:

(1 + i)³ = i³ + i² + i + 1.

The basic complex number relation is:

i² = -1.

Hence:

i³ = i² x i = -1 x i = -1.

Then the expression is given as follows:

i³ + i² + i + 1 = -i - 1 + i + 1 = 0.

The length of the stone walkway would be 536.64 inches.

To find the length of the stone walkway, the landscaper needs to determine the length of the diagonal of the rectangular lawn.

The length of the diagonal can be calculated using the Pythagorean theorem:

[tex]d^2 = l^2 + w^2[/tex]

Where d is the length of the diagonal, l is the length of the rectangle, and w is the width of the rectangle.

So to find the length of the walkway, the landscaper would need to know the length and width of the rectangular lawn.

Suppose a landscaper wants to place a stone walkway from one corner of a rectangular lawn that is 40 feet long and 20 feet wide to the opposite corner.

Using the Pythagorean theorem, we can calculate the length of the diagonal:

[tex]d^2 = 40^2 + 20^2[/tex]

[tex]d^2 = 1600 + 400[/tex]

[tex]d^2 = 2000[/tex]

[tex]d =\sqrt{2000}[/tex]

[tex]d = 44.72 feet[/tex]

Rounding to the nearest inch, the length of the stone walkway would be 44.72 * 12 = 536.64 inches, which can be rounded to 536 inches.

The two numbers are 7/6 and 5 when the sum of two numbers is 3 more than four times the first number.

Let's call the two numbers x and y, where x is the first number and y is the second number.

The problem gives us two equations that relate the two numbers:

[tex]x + y = 3 + 4x\\y - x = 2y - 10[/tex]

We can substitute the expression for y from equation 1 into equation 2:

[tex]y - x = 2(3 + 4x) - 10[/tex]

Expanding the right side and simplifying, we get:

[tex]y - x = 6 + 8x - 10\\y - x = 8x - 4[/tex]

Adding x to both sides:

[tex]y = 9x - 4[/tex]

Substituting this expression for y into equation 1:

[tex]x + (9x - 4) = 3 + 4x[/tex]

Expanding and simplifying the right side:

[tex]10x - 4 = 3 + 4x[/tex]

Subtracting 4x from both sides:

[tex]6x - 4 = 3[/tex]

Adding 4 to both sides:

[tex]6x = 7[/tex]

Dividing both sides by 6:

[tex]x = 7/6[/tex]

Substituting this value of x back into the expression for y:

[tex]y = 9x - 4 = 9 * (7/6) - 4 = 63/6 - 4 = 9 - 4 = 5[/tex]
