Step-by-step explanation:

A group of 10 people is choose a chairperson and vice-chairperson. They put all 10 peoples names into a bar. The first name drawn becomes chair. The second name drawn becomes vice-chair. How many possible combinations of chair and Vice-chair are there ?

This is calculated using the Permutation formula

nPr = n!/(n - r)!

Where:

n = 10 people

r = 2 = 2 positions to be filled , Chairman and Vice chairman

Hence:

10P2 = 10!/(10 - 2)!

= 90 ways

Answer:

x = [tex]\frac{10}{3}[/tex] or [tex]3\frac{1}{10}[/tex]

Step-by-step explanation:

2x - 8 = 12 - 4x

1) Add 8 on boths sides:

2x - 8 + 8 = 12 - 4x + 8

2x = 20 - 4x

2) Add 4x to both sides:

2x + 4x = 20 - 4x + 4x

6x = 20

3) Divide 6 on both sides

[tex]\frac{6x}{6} = \frac{20}{6}[/tex]

x = [tex]\frac{10}{3}[/tex] or [tex]3\frac{1}{10}[/tex]

Step-by-step explanation:

Answer:

(-5, -1)

Step-by-step explanation:

When two lines intersect, their x and y values are equal. So,

x = 3y - 2 must equal -7 - 2y = x

x = 3y - 2 = -7 - 2y = x

Let's look at the two middle equations and solve for y.

3y - 2 = -7 - 2y

Add 2y to both sides

5y - 2 = -7

Add 2 to both sides.

5y = -5

y = -1

Now, let's find x. You can use either equation for this step.

When y = -1, then 3y - 2 =

(3)(-1) - 2 = -3 - 2 = -5

So, x = -5, and y = -1

Thus, the answer is (-5, -1)

Answer: 2 independent sample test of proportions

Step-by-step explanation:

The teo independent sample test of proportion is also referred to as the two proportion z-test and it simply allows the researcher to compare the two proportions in order to ascertain if they're the same or not.

In this case, the null hypothesis will be that that the proportions given in the research are the same while the alternate hypothesis will be that there is a difference between the proportions given.

The kind of analysis that would be most adequate for the given study:

Test of 2 Independent Proportions.

The test of two independent proportions is characterized as the method of study in which samples are opted randomly and allowed to remain independent.

In such a study, a minimum of 5 failures and successes are considered to reach a conclusion.

In the given situation, the samples of males and females are random and permitted to stay free("continue after the mission") and evaluated after a time to take the deduction.

Answer:

18

Step-by-step explanation:

Answer:

Write the problem as a mathematical expression. (5,5), (5,−8)

Use y=mx+b to calculate the equation of the line, where m represents the slope and b represents the y-intercept. To calculate the equation of the line, use the y=mx+b format.

Slope is equal to the change in y over the change in x , or rise over run.

m=(change in y)/(change in x)

The change in x is equal to the difference in x-coordinates (also called run), and the change in y

is equal to the difference in y-coordinates (also called rise).

m=(y2−y1) / (x2−x1)

Substitute in the values of x and y

into the equation to find the slope.

m=(−8−(5)) / (5−(5))

Finding the slope m.

Undefined

x=5

Step-by-step explanation:

Answer:

m = undefined

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Step-by-step explanation:

Step 1: Define

Point (5, 5)

Point (5, -8)

Step 2: Identify

(5, 5) → x₁ = 5, y₁ = 5

(5, -8) → x₂ = 5, y₂ = -8

Step 3: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Here we see that we have a number divided by 0. Since we know that we cannot divide any number by 0, our slope will be undefined. This will be a vertical line on a Cartesian plane of x = 5.

Complete question

A coffee is sitting on Mr. Hunt's desk cooling. It cools according to the function T=70(0.80)^x+20, where x is the time in minutes and T is the temperature in degree Celsius. WHAT IS THE INITIAL temperature of the coffee

The initial temperature occurs at x = 0

Substitute x = 0 into the expression;

T=70(0.80)^x+20

T =70(0.80)^0+20

Since any value raise to power of zero is 1, hence;

T = 70(1)+20

T = 70+20

T = 90 degree Celsius

Hence the initial temperature of the coffee is 90 degrees

The initial temperature of the coffee is 90 degrees.

The function is represented as:

[tex]\mathbf{T = 70(0.80)^x + 20}[/tex]

At the initial temperature, x = 0.

So, we have:

[tex]\mathbf{T = 70(0.80)^0 + 20}[/tex]

Expand

[tex]\mathbf{T = 70 \times 1 + 20}[/tex]

Multiply

[tex]\mathbf{T = 70 + 20}[/tex]

Add

[tex]\mathbf{T = 90}[/tex]

Hence, the initial temperature of the coffee is 90 degrees.

Step-by-step explanation:

60% = 0.6

15% = 0.15

10 = 0.15

Answer:

24

Step-by-step explanation:

Let x represent total number of vehicles

Let T represent number of trucks

Let V represent number of vans

Let B represent number of buses

Convert percent's to decimals:

60% = 0.6

15% = 0.15

Set up equations:

T = 0.6x

V= 0.15x

B= (1 - 0.6 - 0.15)x

For buses, the remaining portion of the 100% of vehicles is 100% -60% -15%

Since we know there are 10 buses, set B=10

B= (1 - 0.6 - 0.15)x

10= (1 - 0.6 - 0.15)x

10= 0.25 x

Divide both sides by 0.25 so that we get:

10/0.25 = x

x= 40

We now know there are 40 vehicles present.  To find the number of trucks, we take 60% of the total number of vehicles

T = 0.6x

T= 0.6 (40)

T= 24

Therefore there are 24 trucks.

Given:

The given figure represents the original parallelogram and the reduction.

To find:

The length of side A in the new parallelogram.

Solution:

We know that the original figure is always similar to its reduction. So, both parallelograms are similar to each other.

The corresponding sides of similar figures are proportional.

[tex]\dfrac{45}{18}=\dfrac{5}{A}[/tex]

[tex]45\times A=5\times 18[/tex]

[tex]45A=90[/tex]

Divide both sides by 45.

[tex]A=\dfrac{90}{45}[/tex]

[tex]A=2[/tex]

The length of side A in the new parallelogram is 2 cm. Therefore, the correct option is A.
