A shelf has 4 blue pairs of pants, 2 black pairs of pants, 1 white pair of pants, and 3 tan pairs of pants. You randomly choose a pair of pants from the shelf. What is the probability of choosing a blue pair of pants as a percent? - the answer isn’t 60%.
Answers
Answer:
Probability can best be seen as the total number of “successful” outcomes (non blue pants) divided by the total number of possible outcomes (all pants). Normally, you express probability as a fraction (6/10), a ratio (6:10), or a percentage (60%). You could also express the probability as .6, or 6 out of 10.
My thought process: There are 4 pair of blue pants and 6 pair of non-blue pants. When you pick, you have 4 chances (pants) out of 10 chances (pants) of getting blue, and, therefore, 6 chances (pants) out of 10 chances (pants) of getting “not blue”. That is 60%; 6:10; 6/10; .6; or 6 out of 10.

vocabulary is a repeating decimal a rational number?
a. no because it cannot be written in form of a/b where a and b are intergers and b=0
b. no because it cannot be written in form a b where a and b are integers.
c. yes because it can be written in the form a/b where a and b are integers are b=0
d yes because it can written in the a.b where a and b integers.
Answers
if not d, it’s probably c, but the denominator for a repeating decimal (b) shouldnt always be 0, it could be 1. ex: .333/1
Yes, because it can be written in the form a/b where a and b are integers are b = 0. Then the correct option is C.
What is a rational number?If the value of a numerical expression is terminating then they are the rational number then they are called the rational number and if the value of a numerical expression is non-terminating then they are called an irrational number.

Graph the description of each line A line has a slope of -3 and a y-intercept of 3.
Answers
Answer:
The equation is y = -3 + 3
Step-by-step explanation:
It will go through (0,3) and it wil go up 3 right one.
Answer:
equation: y= -3x+3
Step-by-step explanation:
Subustitute formula y=mx+b for the slope=m and in this case the slope is -3. and the y intercept=b so if u plug in m and b in the formula y=mx+b you get y=-3x+3. next, since the slope, put the -3 over 1 to create a fraction. next, plot the point (0,3) as the y-int. then follow the pattern -3 down right 1. So the points to plot are (0,3), (1,0) (2,-3)

The table shows input and output values of a function given a rule. Which function represents the rule?
Input: x, a number; Output: y, 3 less than 2 times x
Input,x -2 -1 0 1 2
Output,y -7 -5 -3 -1 1
A. Y= 2x - 3
B. Y= -2x + 3
C. Y= -3x - 2
D. Y= 3x + 2
Answers
Because 2 times x is 2x, and 3 less than that is -3. So we can write them into 2x - 3 = Y
The correct function for the given rule will be;
⇒ Y = 2x - 3
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Input: x, a number
Output: y, 3 less than 2 times x
And,
Input, x -2 -1 0 1 2
Output, y -7 -5 -3 -1 1
Now,
Since, For the function we have;
Input: x, a number
Output: y, 3 less than 2 times x
So, We get;
The function is,
⇒ Y = 2x - 3
And, Here given that;
Input, x -2 -1 0 1 2
Output, y -7 -5 -3 -1 1
Substitute all the values and check it as;
⇒ Y = 2x - 3
Put Y = - 7 , x = - 2
⇒ - 7 = 2 × - 2 - 3
⇒ - 7 = - 4 - 3
⇒ - 7 = - 7
Thus, The value of function is,
⇒ Y = 2x - 3

On a math test, 4 out of 20 students received an A. Two students are randomly selected without replacement, and the first student has an A. What is the probability of the second student having an A?
Answers
Answer:
Step-by-step explanation:
The answer should be 20% chance
Two students selected without replacement, and the first student and second student having is 16/95
Probability-based problem:What information do we have?
Number of total students = 20
Number of students having A = 4
Two students selected without replacement, and the first student has an A = 4/20 × 16/19
Two students selected without replacement, and the first student has an A = 64 / 380
Two students selected without replacement, and the first student has an A = 16 / 95
Probability of the second student having an A = 16/20 × 4/19
Probability of the second student having an A = 64 / 380
Probability of the second student having an A = 16 / 35

Jane is training for a triathlon. After swimming a few laps, she leaves the health club and bikes 16 miles south. She then runs 12 miles west. Her trainer bikes from the health club to meet Jane at the end of her run.
How much farther does Jane travel than her trainer? Answer the questions to find out.
1. What is the total distance Jane travels biking and running? Include units with your answer.
2. Use the Pythagorean theorem to write an equation for the distance Jane's trainer bikes.
3. Solve your equation to find the distance Jane's trainer bikes. Show your work.
4. How much farther does Jane travel than her trainer?
Answers
Answer:
Part 1. 28 miles
Part 2. 16^2 + 12^2 = c^2
Part 3. 8 miles. All work is in step by step explanation.
Part 4. 8 miles
Step-by-step explanation:
Part 1. The total distance that Jane travels biking and running is 28 miles. This is because we add 16 and 12 which is her total route.
Part 2. The Pythagorean theorem is a^2 + b^2 = c ^2. In this case, the variable a is Jane's bike route(16 miles), the variable b is Jane's running route(12 miles), and the variable c is the Trainer's biking route as given. If we replace all variables with the values in miles, the equation would be 16^2 + 12^2 = c^2.
Part 3. WORK USED FROM EQUATION
16^2 = 16*16 = 256
12^2 = 12*12 = 144
Now we replace the numbers with the exponents with the solved numbers.
256 + 144 = c^2
256 + 144 = 400
400 = c^2
c = sqrt400
c = 20
Finally, we take the value of c and subtract it from the total distance of Jane's route which is 28 miles(as explained above).
28 - 20 = 8.
Hence, the answer is 8 miles
