Step-by-step explanation:
Rasheed is getting dressed in the dark. He reaches into his sock drawer to get a pair of socks. He knows that his sock drawer contains six pairs of socks, and each pair is a different color. Each pair of socks is folded together. The pairs of socks in the drawer are red, brown, green, white, black, and blue.
A. How many possible outcomes are there in the experiment?
B. What are the possible outcomes of the experiment?
C. List the sample space for the experiment.
D. Calculate P(blue).
E. Calculate P(not purple)
Answer:
Part A: There are 6 possible outcomes of this experiment.
Part B: There are 6 possible outcomes of the experiment ; red, brown, green, white, black, and blue ( equal)
Part C:
Sample Space = { red, brown, green, white, black, blue }
Part D:
P (blue)= 1/6
Part E:
P (not purple)= 1
Step-by-step explanation:
Part A:
There are 6 possible outcomes of this experiment.
As there are 6 pairs of socks. Each pair is folded together so that the socks cannot be mixed up . There is 1 chance of choosing each pair of socks.
Part B:
The chosen socks can be any of the following red, brown, green, white, black, and blue so there are 6 possible outcomes of the experiment ; red, brown, green, white, black, and blue (all have equal probability) .
Part C:
The sample space contains all the possible outcomes of the event.
Sample Space = { red, brown, green, white, black, blue }
Part D:
P(blue)= No of favorable outcomes/ Total no of outcomes
P (blue)= 1/6
Part E:
P (not purple)= 1
As the total probability is always equal to 1 and we want to find the probability of the color which is not given in the list
P( purple) = 0/6= 0
And the probability of not purple is given by the formula
P (not purple) = 1- P (purple)
= 1-0= 1
1 indicates that the event of any other color except purple must occur which is equal to the probability of not purple.
This can be solved by complement rule also.

pythagorean theorem
Answer:
The pythagorean theorem is a theorem which states that the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.
Pythagorean theorem
in the right angle triangles there is a relationship that governs the length of the three sides. if we knows the length of any two sides, the third side may be calculated by the use of the Pythagorean theorem.
This theorem states that the square on the hypotenuse of a right angled triangle is equal to the sum of the squares on the remaining two sides.
we only use Pythagorean theorem to find the length of the missing side of a right angled triangle only.
What is the greatest common factor of 42 and 50
The greatest common factor of 42 and 50 is 2.
The given numbers are 42 and 50
The greatest common factor (GCF) of two numbers is the largest number that divides both of them evenly.
To find the GCF of 42 and 50,
We can start by listing the factors of each number.
The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.
Similarly, the factors of 50 are 1, 2, 5, 10, 25, and 50.
By comparing the factors,
We can see that the highest common factor is 2.
Therefore, the GCF of 42 and 50 is 2.
This means that 2 is the largest number that can divide both 42 and 50 without leaving a remainder.

La relación del aspecto de una pantalla o la relación entre el ancho y alto de una televisión es de 16:9. El tamaño de una TV está dado por la distancia diagonal de la TV, si se sabe que una HDTV tiene 41 pulgadas de ancho, determina el tamaño de la pantalla.
Answer:
[tex]23\frac{1}{16}[/tex] pulgada
Step-by-step explanation:
[tex]\frac{16}{9} =\frac{41}{y}[/tex]
16 × y = 9 × 41
16y = 369
16y ÷ 16 = 369 ÷ 16
[tex]y=23\frac{1}{16}[/tex]

Which ope of fuel recorded a greater percentage change in pace over the previous month? Justity your answer. (5 points)
Answer:
A. Increasing by 4%.
Step-by-step explanation:
Answer:
A) The price of product A is increasing by 3% per year.
(B) The product A recorded a greater percentage change in price over the previous year.
Step-by-step explanation:
(A)
The function representing the price, in dollars, of product A after x years is:
FA(x)=0.69*(1.03)x
The function FA(x)can be written as:
FA(x)=0.69*1+(0.03)x
The function FA(x) is similar to the exponential growth function, y=a(1+r)x .
Here r is the growth rate.
Thus, it can be said that the price of product A is increasing by 3% per year.
(B)
Consider the data of product B for the year 3 and 4.
The price of product B for year 3 and 4 are 10,303.01 and 10,406.04.
Compute the percent price change from year 3 to 4 as follows:
10406.04-10303.01/10303.01*100
which is 0.999%
~1%
The price of product B is increasing by 1% per year.
Thus, the product A recorded a greater percentage change in price over the previous year.

The distance d, in kilometers, that a car travels at a speed of 80 km per hour, for t hours, is given by the equation d= 80t. What is the inverse to represent time, t as a function of distance, d?
Choices:
1. t= d/80
2.t= 80/d
3.t= 80d
Answer:
The car was traveling for 1.5 hours.
Step-by-step explanation:
Given that distance d, in kilometers, that a car travels at a speed of 80 km per hour , for t hours, is given by the equation d=80t.
Here wee need to find the time if the car has gone 120 kilometers.
That is
d = 120 km
we need to find t.
d=80t
120 = 80 x t

This Must Only Have One Solution, Because The Right Side Of The Equation Is Just Plainly Ten. Lets Solve This:
5x + 3x - 4 = 10
Add Four To Both Sides To Begin Simplifying.
5x + 3x = 14
Now, Combine Like Terms.
8x = 14
Divide:
8x/8 = 1X = X
14/8
X = 14/8
14/8 = 1.75
X = 1.75
Check:
(5 * 1.75) + (3*1.75) - 4 = 10
8.75 + 5.25 - 4 = 10
14 - 4 = 10
10 = 10.
This Is True, So X Does Equal 1.75

If 25% of a number is 65 and 60% of the same number is 156, find 35% of that number.
Answer:
35% of that number is 91.
Step-by-step explanation:
we need to first find 25% of what number equals 65.
65×100÷25 = 260
Then, if you use the same method again, 60% of 260 would be 156.
We know "that" number is 260, and all we need to do is find 35% of it.
35% of 260 = 91
Hope this helped :)
