Using it's concept, considering a spinner with four sections and a die with 6 numbers, there is a [tex]\frac{1}{6}[/tex] probability of landing on red and rolling a number greater than 2.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem:

The events are independent, hence:

[tex]P(A \cap B) = P(A)P(B) = \frac{1}{4} \times \frac{4}{6} = \frac{1}{6}[/tex]

Answer:

X=55

Step-by-step explanation:

It says 15, so what you want to do is times 15x14 because those are the only sides of the shape. After you multiply 15x14 which is 60, you need to minus 5 because it shows a subtraction sign. So, 60-5= 55. X=55

Step-by-step explanation:

the slope is the ratio of "y coordinate change / x coordinate change" when going from one point to the other.

so, we see

x changes by +8 (from 5 to 13).

y changes by -6 (from -3 to -9).

so, the slope is -6/+8 = -3/4

Hello.

Let's find the slope using the slope formula:

[tex]\mathrm{\displaystyle\frac{y2-y1}{x2-x1} }[/tex]

[tex]\mathrm{\displaystyle\frac{-9-(-3)}{13-5} }[/tex]

[tex]\mathrm{\displaystyle\frac{-9+3}{13-5} }[/tex]

[tex]\mathrm{\displaystyle\frac{-6}{8} }[/tex]

The fraction can be simplified:

[tex]\mathrm{\displaystyle-\frac{3}{4} }[/tex]

Therefore, the slope is

[tex]\mathrm{\displaystyle-\frac{3}{4} }[/tex]

I hope it helps.

Have a nice day.

Formulae

Slope-intercept form of a linear function: [tex]y = mx + b[/tex]

(where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept)

Point-slope form of a linear function:  [tex]y-y_1=m(x-x_1)[/tex]

(where [tex]m[/tex] is the slope and [tex](x_1,y_1)[/tex]  is a point on the line)

The factors of the given expression will be 7,x, x, y, and ( x + 2y²- y).

We have the expression:

7x³y+ 14x²y³-7x²y²

A factor is a number that divides another number completely.

Let us take '7x²y' as common in the above expression

7x²y( x + 2y²- y)

7. x.x.y ( x + 2y² - y)

Further, we cannot make any factor.

Therefore, the factors of the given expression will be 7,x, x, y, and ( x + 2y²- y).

The area of the garden is the amount of space on the garden.

The dimensions of the garden is given as:

15 meters by 20 meters

Let the width of the pedestrian pathway be x.

So, the area of the total garden is:

[tex]Area=(x + 15)(x + 20)[/tex]

In (a), we have:

[tex]Area=(x + 15)(x + 20)[/tex]

The total area is given as: 336.

So, we have:

[tex](x + 15)(x + 20) = 336[/tex]

Expand

[tex]x^2 + 35x + 300 = 336[/tex]

Collect like terms

[tex]x^2 + 35x + 300 - 336 = 0[/tex]

Evaluate

[tex]x^2 + 35x - 36 = 0[/tex]

Expand

[tex]x^2 + 36x -x - 36 = 0[/tex]

Factorize

[tex]x(x + 36) -1(x +36) = 0[/tex]

Factor out x + 36

[tex](x + 36)(x -1) = 0[/tex]

Solve for x

x = -36 or x =1

The width cannot be negative.

Hence, the width of the pathway is 1 meter
