Step-by-step explanation:

Sample space Total sections of spinner = (A, B, C, D) = 4

P(spinner stops on A) = 1 /4

Second spin :

P(stops on B) = 1/4

Third spin :

P(stops on C) = 1/4

Fourth spin :

P(stops on D) = 1/4

Hence,

P(A then B then C then D)

1/4 * 1/4 * 1/4 * 1/4 = 1

Answer:

12meters

Step-by-step explanation:

Given data

Lenght = 36 meters

Width = 15 meters

The dimension of the diagonal can be gotten via Pythagoras theorem

D^2= L^2+W^2

Substitute

D^2= 36^2+ 15^2

D^2=  1296+225

D^2= 1521

D= √1521

D= 39  meters

Hence the distance while walking on the side is

=36+15

=51 meters

Hence the difference is

=51-39

=12meters

Answer:

The sum and difference formulas can be used to find the exact values of the sine, cosine, or tangent of an angle. The angle sum identities take two different formulas: sin(A+B) = sinAcosB + cosAsinB. cos(A+B) = cosAcosB − sinAsinB. The difference formula for cosines states that the cosine of the difference of two angles equals the product of the cosines of the angles plus the product of the sines of the angles. The sum and difference formulas can be used to find the exact values of the sine, cosine, or tangent of an angle.

Negative Correlation

Strong Correlation

Linear

Step-by-step explanation:

The points slope downward, and downward slopes = negative

This is a strong correlation because the points are in a distinct line, not scattered.

This is Linear because it is a straight line.

Step-by-step explanation:

hello :

8(e)^2x+1=4

(e)^2x+1=4/8 = 1/2

so : 2x+1 = ln(1/2)

2x = ln(1/2) - 1

x = (ln(1/2) - 1)/2

The solution to the given exponential function is x = [ ln(0.5) - 1]/2

The standard exponential equation is expressed as  y = ab^x

Given the expression

8(e)^2x+1=4

Divide both sides by 8

(e)^2x+1=4/8

(e)^2x+1 = 1/2

Take the ln of both sides

ln(e)^2x+1  ln(1/2)
2x + 1 = ln(0.5)

2x = ln(0.5) - 1
x = [ ln(0.5) - 1]/2

Hence the solution to the given exponential function is x = [ ln(0.5) - 1]/2

Answer:

[tex] \boxed{y = 10} [/tex]

Step-by-step explanation:

-12 = 6y + 18 – 9y

[Group like terms 6y and -9y]

-12 = (6y – 9y) + 18

[Simplify the expression]

-12 = -3y + 18

[Subtract 18 from both sides, subtraction property of equality, to isolate the variable and the value]

-12 = -3y + 18

–18 –18

-30 = -3y

[Divide by -3 from both sides, division property of equality, to get the variable y by itself]

-30 = -3y

÷(-3) ÷(-3)

10 = y

[Symmetric property of equality, if b = a, then a = b]

y = 10

Answer:

x=8 and y=17

Step-by-step explanation:

hope this helps

let the price of pizza and soda( per 2 litre bottle) be x and y

from 1st condition

12x+2y=137.6.....(1)

from 2nd condition

x+y =11.95.......(2)

multiply eq. (2) by 2

2x+2y=23.9.....(3)

subtracting (1) and (3)

12x+2y=137.6

2x+2y= 23.9

10x = 113.7

x=113.7/10

x=11.37

2(11.37)+2y=23.9

22.74+2y=23.9

2y=23.9-22.7

2y=1.2

y=0.6

So the prices of  the pizza and soda are 11.37 and 0.6 dollars.

Each pizza costs approximately $10.99, and each 2-liter of soda costs approximately $0.96.

Let x be the cost of one pizza, and y be the cost of one 2-liter of soda.

According to the information given, we can write the following two equations:

1. For the pizza and soda purchased for the theater party:

12x + 6y = 137.64

2. For the pizza and soda purchased for Katya's family:

1x + 1y = 11.95

Now, we have a system of two equations with two variables. We can solve it to find the values of x and y.

First, let's solve the second equation for y:

y = 11.95 - x

Next, substitute this value of y into the first equation:

12x + 6(11.95 - x) = 137.64

Now, simplify and solve for x:

12x + 71.7 - 6x = 137.64

Combine like terms:

6x + 71.7 = 137.64

Subtract 71.7 from both sides:

6x = 65.94

Finally, divide by 6:

x = 65.94 / 6

x ≈ 10.99

Now that we have the value of x, which is the cost of one pizza, we can find the cost of one 2-liter of soda using the second equation:

y = 11.95 - x

y ≈ 11.95 - 10.99

y ≈ 0.96

So, each pizza costs approximately $10.99, and each 2-liter of soda costs approximately $0.96.
