Which table represents a function?

Answers

Explanation

A function is a set of relation without repetitive domain. That means we cannot have the same value of x in a set.

Example

{(1,1),(1,2),(2,4),(3,9)}

This is not a function because the relation has same two x = 1 which does not make it a function.

{(1,1),(2,4),(3,9)}

This is a function because there are no same x-values or repetitive domain in a single set.

Back to the question, we can find which table represent a function by looking at the x-value table. If there are two same or more x-values, it is not a function.

Answer

The answer is the left bottom table as the other table have two same x-values.

A bottled water company runs a promotion in which 1 out of every 4 bottles has the word "Winner" printed under the
cap. Winners receive a free bottle of water. A store owner notices that in the last 4 bottles of water purchased, 2
have been winners. Using the table, what is the probability of getting 2 or more "Winner" caps on 4 bottles of water?

Answers

Answer:

0.262

Step-by-step explanation:

Edge 2021

The probability of getting 2 or more "Winner" caps on 4 bottles of water

is 0.2616.

What is a binomial distribution in probability?

In an experiment with two possible outcomes, the likelihood of exactly x successes on n repeated trials is known as the binomial probability.

The binomial probability is, [tex]^nC_xP^xq^{n - x}[/tex].

Let, p be the probability of winning,

Given, 1 out of every 4 bottles has the word "Winner".

Therefore, p = 1/4 and we know q = 1 - p = 3/4.

So, The probability of getting 2 or more "Winner" caps on 4 bottles of water

is P(X ≥ 2) which is, P(X = 2) + P(X = 3) + P(X = 4).

P(X ≥ 2) = [tex]^4C_2p^2q^2 + ^4C_3p^3q^1 + ^4C_4p^4q^0[/tex].

P(X ≥ 2) = 6(1/4)²×(3/4)² + 4(1/4)³×(3/4) + 1(1/4)⁴×1.

P(X ≥ 2) = 0.2109 + 0.0468 + 0.0039.

P(X ≥ 2) = 0.2616 or 26.16%.

Jay makes a base salary of $2000 per month. Once he reaches $50000 in total sales, he earns an additional 5% commission (salary) on the amount of sales over $50000. Let s be the amount of his total sales for the month and j(s) be the amount of his salary for the month.

Answers

Answer:

[tex]j(s) = 0.05s -500[/tex]

Step-by-step explanation:

Given

[tex]Base\ Salary = 2000[/tex]

[tex]Commission = 5\%[/tex] on Sales over 50000

Required

Determine the function j(s) for sales over 50000

Represent the total sales in a month with s.

Sales over 50000 in that month will be: s - 50000

So, the function j(s) is:

j(s) = Base Amount + Commission * Sales over 50000

[tex]j(s) = 2000 + 5\% * (s - 50000)[/tex]

Convert % to decimal

[tex]j(s) = 2000 + 0.05 * (s - 50000)[/tex]

Open bracket

[tex]j(s) = 2000 + 0.05 * s - 0.05 * 50000[/tex]

[tex]j(s) = 2000 + 0.05s - 2500[/tex]

a rectangle has a perimeter of 158 cm and the given area of 804 cm^2 Its length is 7 more than five times its width. Write and solve a system of equations to find the dimensions of the rectangle.

Answers

so i'm using the letter l for length w for width p for perimeter and a for area

l = 5w + 7
a = (5w+7) x w

p =2(5w+7) + 2w
= 10w + 14 +2w
p = 12w + 14
158cm = 12w + 14
12w = 144
w = (144/12) = 12

l = 5w + 7
so 5 x 12 + 7 = 67

width = 12cm length = 67cm

proven: area = 804cm^2 which is 12 x 67

hopes that u can understand my workings and that this helps :)
