Answer:

The probability of seeing a person wearing black shoes before seeing a person wearing white ones = 60%

Step-by-step explanation:

People watched walking down the street = 100%

People wearing black shoes = 1/2 = 50%

People wearing white shoes = 1/3 = 33.33%

People wearing red shoes = 1/6 = 16.67%

Probability of black shoes to white shoes = percentage of persons wearing black shoes/sum of the percentages of people wearing black and white shoes)

= 50% : 33.33%

= 60% (50%/83.33%)

When expressed in ratio terms, it means that you will see 1.5 (50%/33.33% or 1.5 : 1) persons wearing black shoes before you see a person wearing white shoes.

Answer:

Median.

Step-by-step explanation:

The median is the value separating the higher half of a data sample, a population, or a probability distribution, from the lower half. In simple terms, it may be thought of as the "middle" value of a data set. For example, in the data set {1, 3, 3, 6, 7, 8, 9}, the median is 6, the fourth number in the sample. The median is a commonly used measure of the properties of a data set in statistics and probability theory.

How to improve in math?
Arte-miy333 [17]
The best way is to do problems over and over again and making mistakes with them.There is no point in doing them if you get correct answers.
When you make mistakes you ask someone what’s wrong and try not to make that mistake again.
That’s how I became a master at maths and physics.

As for help with calculus the important thing is to understand how graphing works.
Once you got that do more questions.
So basically to summarise make mistakes don’t repeat and find out how it works

Hope this helps:)

Solve each equation. List any restrictions. Check your solutions. <br> 12/x+11=17
Thepotemich [5.8K]
12+11x=17x11x+12=17x
(both sides of the equation)
11x+12−17x=17x−17x
(Subtract 17x from both sides)
−6x+12=0−6x+12−12=0−12
(Subtract 12 from both sides)
−6x=−12−6x−6=−12−6
(Divide both sides by -6)
x=2
Check answers. (Plug them in to make sure they work.)
x=2
(Works in original equation)
