What is Probability?

Probability is an area of mathematics that deals with numerical representations of how probable an event is to occur or how likely a statement is to be true. The probability of an occurrence is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty.

Solution:

Total Number of Regular Soft Drinks = 18

Total Number of Diet Soft Drinks = 12

Total Drinks = 18 + 12 = 30

Probability of selecting Diet Soft Drink in the first two attempt = 12/30 * 11/29 * 18/28 = 2376 / 24360

Probability of selecting Diet Soft Drink in the first and last attempt = 12/30  * 18/29 * 11/28 = 2376 / 24360

Probability of selecting Diet Soft Drink in the second and last attempt = 18/30  * 12/29 * 11/28 = 2376 / 24360

Total Probability = 3 * 2376 / 24360

Total Probability = 2376 / 8120

Total Probability = 297 / 1015

There are 788,872,812,500 ways to select a committee of 10 senators consisting of 5 men and 5 women.

We need to select 5 men out of 85 and 5 women out of 15, and then combine them to form a committee of 10. We can do this using the combination formula:

\(${{85}\choose{5}}$\) ways to select 5 men from 85, and\(${15\choose5}$\)ways to select 5 women from 15.

To form the committee, we need to combine these two groups of 5. We can do this by multiplying the number of ways to select each group:

\((855)⋅(155)=85!5!80!⋅15!5!10!=788872812500.( 585​ )⋅( 515​\)

Step-by-step explanation:

The integral: S1 0 (-x³ - 2x² - x + 3)dx is -1/12

An integral is a mathematical operation that calculates the area under a curve or the value of a function at a specific point. It is denoted by the symbol ∫ and is used in calculus to find the total amount of change over an interval.

To evaluate the integral:

\($ \int_0^1 (-x^3 - 2x^2 - x + 3)dx $\)

We can integrate each term of the polynomial separately using the power rule of integration, which states that:

\($ \int x^n dx = \frac{x^{n+1}}{n+1} + C $\)

where C is the constant of integration.

So, we have:

\($ \int_0^1 (-x^3 - 2x^2 - x + 3)dx = \left[-\frac{x^4}{4} - \frac{2x^3}{3} - \frac{x^2}{2} + 3x\right]_0^1 $\)

Now we can substitute the upper limit of integration (1) into the expression, and then subtract the result of substituting the lower limit of integration (0):

\($ \left[-\frac{1^4}{4} - \frac{2(1^3)}{3} - \frac{1^2}{2} + 3(1)\right] - \left[-\frac{0^4}{4} - \frac{2(0^3)}{3} - \frac{0^2}{2} + 3(0)\right] $\)

Simplifying:

\($ = \left[-\frac{1}{4} - \frac{2}{3} - \frac{1}{2} + 3\right] - \left[0\right] $\)

\($ = -\frac{1}{12} $\)

Therefore,

\($ \int_0^1 (-x^3 - 2x^2 - x + 3)dx = -\frac{1}{12} $\)

If the volume is 47 cm³ , then the height of the cone is approximately 5 cm and volume of cone is given by ( 1/3 ) πr²h

What is a Cone?

A cone is a three-dimensional shape in geometry that narrows smoothly from a flat base (usually circular base) to a point(which forms an axis to the center of base) called the apex or vertex.

The volume of a cone is given by the equation

Volume of Cone = ( 1/3 ) πr²h

where r is the radius of the cone

h is the height of the cone

Given data ,

Let the radius of the cone be = r

Now , the value of r = 3 cm

So , the equation will be

The volume of the cone is given by the formula ,

Volume of Cone = ( 1/3 ) πr²h

where r is the radius of the cone

h is the height of the cone

a)

If the volume is 47 cm³, then the height of the cone is approximately 5 cm

So , substitute the values in the equation , we get

Volume of Cone = 47 cm³

So ,

( 1/3 ) πr²h = 47 cm³

Radius of cone r = 3 cm

Height of cone h = 5 cm

( 1/3 ) πr²h = 47 cm³

( 1/3 ) x 3.14 x 3 x 3 x 5 = 47

3.14 x 15 = 47

47 = 47

Therefore , the solution is true

Hence , If the volume is 47 cm³, then the height of the cone is approximately 5 cm and the volume of cone is given by ( 1/3 ) πr²h

If the grocery bill before tax is $265.24 and you have to pay 7.3% tax, then he has to pay $284.6 for the grocery bill

The amount of the grocery bill before tax = $265.24
The percentage of tax = 7.3%

The amount of tax = The price of the grocery bill before tax × (7.3/100)

Substitute the values in the equation

= 265.24 × (7.3/100)

= 265.24 × 0.073

= $19.36

The final bill including tax = The price of the grocery bill before tax + The amount of tax

Substitute the values in the equation

= 265.24 + 19.36

The measure of length PQ will be 22 units.

A triangle's third side is stated to be parallel to the line segment uniting its two midpoints, and it is also half as long as the third side.

Given:

PQ = 5x + 62, and MN = 6x-4

Now, using Mid- Point Theorem

PQ= 1/2 MN

-5x+ 62 = 1/2( 6x - 4)

-5x+ 62 = 3x - 2

-5x- 3x = -2 - 62

-8x = -64

x= 8

PQ= 5x+ 62 = -5(8) + 62 = -40 + 62 = 22

Hence, the measure of PQ is 22 units.

Answer: So you are going to make an equation first.

Step-by-step explanation:

first we know that for the first 2 hours the snow fell at an inch an hour. so we are going to make our first plots ( I suggest using an online site like geogebra or desmos to start out with before plotting for your assingment)

our first plot is going to be at (1,1) or 1 over and 1 up. remember points are in the form of (x,y). then (2,2)

Now we see that it has changed  now there is no  new snow for 6 hours so you are going to have a flat line so its going to be (2,2) then its going to continue that way as (3,2),(4,2), (5,2) (6,2)(7,2)(8,2).

It starts snowing again and now we have a new thing to plot the snow is falling at a constant of 3 inches an hour for the next 5 hours so now we are going to plot hte points to get our points we are going add 3 inches to our current inches each new hour. so its going to be (9,(2+3)) which is (9,5) and continue on doing that so we will have the plots (10,8) (11,11) (12,14) (13,17). and now we connect our plots by creating segments so then you do that on your thing and youre set to go I hope this helps.

We have two problems with change of units.

Here we know that with one tea bag we can make 180 ml of tea, rewriting this in liters, we need to use that:

1 ml = 10^-3 L

180 ml = 180*(10^-3 L) = 0.18 L

Now we also know that in one box we have 24 teabags, the total amount of tea that we can make is:

24*0.18 L = 4.32 L

First, he dug 4,5 meters, and then he dugs another 120cm.

Using that:

1m = 100cm

We can rewrite:

120 cm = (120/100) m = 1.2m

Then the total amount that he dug is:

4.5m + 1.2m = 5.7m

Then we know that the water in the hole is 230cm deep, writing this in meters we have:

230 cm = 230/100 m = 2.3m

Then the part of the well that is not filled with water is given by:

5.7 m - 2.3m = 3.4m

This means that 3.4 meters of the well are not filled with water.

For a function to be continuous at an x-value of -3 you need to make sure two things line up:

First, we need to show that the limit from the left equals the limit from the right.

     \(\lim_{x \to -3^{-}} f(x) = \lim_{x \to -3^{+}} f(x)\)

Second, we need to show that this limit equals the functions value.

    \(\lim_{x \to -3} f(x) = f(-3)\)

The left hand limit involves the first piece, f(x) = x^2 - 9:

    \(\begin{aligned} \lim_{x \to -3^{-}} f(x) &= \lim_{x \to -3^{-}} (x^2-9)\\[0.5em]&= (-3)^2-9\\[0.5em]&= 0\endaligned}\)

The right hand limit invovles the second piece, f(x) = 0:

    \(\begin{aligned} \lim_{x \to -3^{+}} f(x) &= \lim_{x \to -3^{+}} (0)\\[0.5em]&= 0\endaligned}\)

Since the two one-sided limits do match, we can just say:

    \(\lim_{x \to -3} f(x) = 0\)  

(no one-sided pieces needed now)

So that was step #1, to make sure the limit exists.  Next we need to make sure the limit is headed to the same place where the functions.  Since we're using x=-3, we'll use the top piece of the function because x=-3 fits with that piece ( x ≤ -3 ).

    \(f(-3) = (-3)^2-9 = 0\)

From this, we know that \(\lim_{x \to -3} f(x) = f(-3)\), so the function is continuous at -3.  (We also know parabolas and lines are continuous in general, so we only needed to check where the two pieces came together at x = -3.)

Answer:

(- 1, 5 )

Step-by-step explanation:

Given the 2 equations

x + 2y = 9 → (1)

5x - y = - 10 → (2)

Multiplying (2) by 2 and adding to (1) will eliminate the y- term

10x - 2y = - 20 → (3)

Add (1) and (3) term by term to eliminate y

11x + 0 = - 11

11x = - 11 ( divide both sides by 11 )

x = - 1

Substitute x = - 1 into either of the 2 equations and solve for y

Substituting into (1)

- 1 + 2y = 9 ( add 1 to both sides )

2y = 10 ( divide both sides by 2 )

y = 5

solution is (- 1, 5 )

x + 2y = 9 x + 2y = 9

=====》

5x - y = - 10 (×2) 10x - 2y = - 20

+____________

11x + 0 = - 11

11x = - 11

x = - 1

Thus :

- 1 + 2y = 9

Add both sides 1

2y - 1 + 1 = 9 + 1

2y = 10

Divide both sides by 2

2y ÷ 2 = 10 ÷ 2

y = 5
