4. Which set of ordered pairs represents a function?

(1) {(0,4), (2,4),(2,5)}
(2){(6,0), (5,0),(4,0)}
(3) {(4,1),(6,2), (6,3), (5,0)}
(4) {(0,4),(1,4), (0,5),(1,5)}​

Answers

Answer 1

Answer: (2) {(6,0), (5,0),(4,0)}

It is a function, where each value is associated with exactly one output.

Step-by-step explanation:

A relation is said to be a function if the first components of the ordered pairs are associated with exactly one value of the second components of the ordered pair.

(1) {(0,4), (2,4),(2,5)}

here 2 is associated with 2 different values of second component.

Thus it is not a function.

(2) {(6,0), (5,0),(4,0)}

It is a function, where each value is associated with exactly one output.

(3)  {(4,1),(6,2), (6,3), (5,0)}

It is not a function as 6 is associated with 2 different values of second component.

(4) {(0,4),(1,4), (0,5),(1,5)}​

It is not a function as 0 and 1 are associated with 2 different values of second component.

Step-by-step explanation:

Because of the givens (a right angle a common Hypotenuse and a leg in each triangle) ΔSUT and ΔSUV are congruent.         HL

That means that < SUT = < SUV  so what you get out of that is

w + 10 = 3w                                    Subtract w from both sides.

w - w + 10 = 3w - w

10 = 2w                                          Divide both sides by 2

10/2 = 2w/2

w = 5

What value will make the equation true -21 - ? = 1and1/2

Answers

Answer:

the answer would be -21 - (-22 1/2)= 1 1/2

The value that will make the equation true would be -21 - (-22 1/2)= 1 1/2

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given that the equation as;

-21 - (-22 1/2)

Now the mixed fraction is 22 1/2 = 45/2

The difference of the equation is;

-21 - (-22 1/2)

-21 - (-45/2)

= 1 1/2

a) How many products will it be able to sell in year 5?
b) How many products will it have sold over the course of 5 years?

Answers

9514 1404 393

Answer:

246 products in year 52017 products over 5 years

Step-by-step explanation:

The n-th term of the geometric series is ...

  an = a1(r^(n-1))

for first term a1 and common ratio r. The common ratio here is the growth factor: 1 -20% = 0.8. This means the 5th term (5th year sales) will be ...

  a5 = 600(0.8^(5-1)) ≈ 246 . . . . . products sold in year 5

The sum is given by ...

  sn = a1(1 -r^n)/(1 -r) = 600(1 -0.8^5)/(1-0.8) = 2017

The company will have sold about 2017 products over 5 years.

Ms. Smith allows her students to choose the mean, median, or mode of their set of test scores to be their final grade. Which measure of center should Erica use to get the highest average if her scores are 80, 90, 70, 60, 90?

Answers

Answer:

Mode

Step-by-step explanation:

because 90 is the grade that shows up the most!

I hope I helped :)

Measure of center that Erica should use is mode to get the highest average on her scores.

What is Mean, Median and Mode?

For a set of data, mean is the average of all the elements in the data set.

Median is the element in the exact middle when numbers are arranged from smallest to largest or largest to smallest.

Mode is the element which is most repeated.

The given data set is,

80, 90, 70, 60, 90

Mean = (80 + 90 + 70 + 60 + 90) / 5 = 78

To find median, firstly arrange the numbers in order.

60, 70, 80, 90, 90

The middle element is the element in the third place, 80 which is the median.

90 is the only element which appears more than once. So mode is 90.

Mode gives the highest score.

Hence Erica should use mode as the measure of center to get the highest average.

Find m∠ABC = 7x - 4 and m∠BDC = 9x - 1 and and m∠ABC = 107°, find x, m∠ABC and m∠BDC.

Answers

Answer:

m<BDC = 62 degrees

Step-by-step explanation:

Using the expression;

<ABC = <ABD + <DBC

107 = 7x-4 + 9x - 1

107 = 16x-5

16x = 107 + 5

16x = 112

x = 112/16

x = 7

Get m<DBC

m<BDC = 9x - 1

m<BDC = 9(7)-1

m<BDC = 63 - 1

m<BDC = 62 degrees

Find the least common multiple (LCM) for the pair of numbers 6 and 18 ​

Answers

Answer:

the lcm is 6

Step-by-step explanation:

6 divided by 3 is 1

18 divided by 3 is 6

6 becomes 3 and 2

Answer:

18

Step-by-step explanation:

Since the question is asking for the least common multiple, you factor out the 6 in 18 and 6. This gives you 631 as the LCM because you have factored out 6 and this is the GCF because there are no more common factors between 3 and 1. Since 631 equals 18, 18 is the LCM
