Probability refers to the branch of mathematics regarding numerical descriptions of how likely an event is to occur. The probability of an event is a number between [tex]\boldsymbol{0}[/tex] and [tex]\boldsymbol{1}[/tex]

[tex]0[/tex] indicates impossibility of the event and [tex]1[/tex] indicates certainty.

If Jackson turns on his favorite TV station at a randomly selected time, the probability that the current show will be on is that ''If you take a very large sample of the times Jackson tunes in to his favorite TV station, a commercial will be on  about [tex]35\%[/tex] of the time.''

Answer:

Slope of line (i) = 1.5

Step-by-step explanation:

The slope of line (ii) = [tex]-\frac{2}{3}[/tex]

* Mathematics rule: The product of slopes of two perpendicular lines = -1

∴ The slope of line (i) = -1 ÷ [tex]-\frac{2}{3}[/tex] = 3/2 = 1.5

Algebraic Expressions

This problem deals with the ability to manage algebraic expressions in two variables.

Recall the perimeter of a triangle is the sum of its three sides. We already know the perimeter of the triangle is:

P=13x+5y

We also know the lengths of two of its sides are 2x+y and 8x+4y. The sum of those sides is:

S2=2x+y+8x+4y

Joining like terms:

S2=10x+5y

The third side must be the difference between the perimeter and the sum above:

S3=13x+5y-(10x+5y)

Operating:

S3=13x+5y-10x-5y

Joining like terms:

S3=3x

The length of the third side is 3x

Answer:

All real numbers are solutions.

Step-by-step explanation:

Let's solve your equation step-by-step.

10−4v=−2−4(−3+v)

Step 1: Simplify both sides of the equation.

10−4v=−2−4(−3+v)

10+−4v=−2+(−4)(−3)+(−4)(v)(Distribute)

10+−4v=−2+12+−4v

−4v+10=(−4v)+(−2+12)(Combine Like Terms)

−4v+10=−4v+10

−4v+10=−4v+10

Step 2: Add 4v to both sides.

−4v+10+4v=−4v+10+4v

10=10

Step 3: Subtract 10 from both sides.

10−10=10−10

0=0

Answer:

Step-by-step explanation:

supplementary angle

7x + 9 + 5x + 3 = 180

12x = 180 - 3 - 9

x = 168 / 12

x = 14

plugin x=14 into the equation

= 7x + 9

= 7(14) + 9

= 107°

plugin x=14 into the equation

= 5x + 3

= 5(14) + 3

= 73°

The number of turns completed in 1 week is 10.5.

Given that,

Based on the above information, the calculation is as follows:

As we know that in one week there are 7 days, so the no of turns in one week is

[tex]= 1.5 \times 7[/tex]

= 10.5

Therefore we can conclude that the number of turns completed in 1 week is 10.5.

Answer:

y = -1/3 x + 7

Step-by-step explanation:

The constant in the end doesn't matter; what matters is the slope. To find a perpendicular slope, all you have to do is take the reciprocal of the slope and multiply it by -1. As mentioned before, the constant in the end doesn't matter, so the answer could also be y = -1/3x + 10, y = -1/3x -1/2, etc...
