Which set of ordered pairs represents a function? *
O {(1,8), (8, 1), (1,5), (5, 1)}
O {(2,1),(3,1),(4,3), (5,3)}
O {(5,1),(3, 8), (3,7), (7.1);
{(5,1),(5,6), (1,3), (9.7)}

Answers

Answer 1

The answer is the second choice.

There cannot be repetitive domains in one set. Therefore, all choices except the second choice have repetitive domains.

Thus, not making them a function but rather a relation instead for other choices. The only relation that is a function here is the second choice.

Answer 2

the second one because the x values should not have repeating numbers

number?

Answers

Answer:36

Given that,

The average of five consecutive numbers is 38. The smallest number to be determined.

What is average?

The average of the values is the ratio of the total sum of values to the number of values.

What is simplification?

The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.

The average of five consecutive numbers is 38.
Let the middle value is a,
Series of 5 number can be given as = (a -2n) , (a-n) , a , (a+n) , (a+2n).
n = 5
Average = ( a-2n +a -n + a +a+n+ a+2n)/5
38 = 5a/5
a = 38
Now smallest and first term (n = 1)   = a - 2n
                                                     = 38 - 2(1)
                                                     = 36

Thus, the required first and smallest term of consecutive terms is 38.

The first term of a geometric sequence is 3 and the 4th is 1029. find the two terms between the 1st and the 4th.

Answers

Two terms between the 1st and the 4th in the given geometric sequence is 21 and 147.

The formula for the nth term in a geometric sequence is given by:

a(n) = a(1) . rⁿ⁻¹

Where:

a(1) = first term

r = common ratio

Parameters given:

a(1) = 3

a(4) = 1029

Substitute n  = 4 into the formula:

a(n) = a(1) . rⁿ⁻¹

a(4) = 3 . r³

1029 = 3 . r³

r³ = 1029/3 = 343

r = 7

Two terms between the 1st and the 4th term is a(2) and a(3).

In a geometric sequence, the following applies:

a(n) = a(n-1) . r

Hence,

a(2) = 3 . r

       = 3 . 7 = 21

a(3) = a(2) . r

       = 21 . 7 = 147

After 4 years, $3,006 deposited in a savings account with simple interest had grown to a total of $3,967.92. What was the interest rate?

Answers

Answer:

So interest rate is 8% per annum

Step-by-step explanation:

Principal amount = $3,006

Amount at end = $3,967.92

Time = 4yrs

interest money = ($3967.92 - $3006)  

also equal to = 4 * (x/100) * $3,006

Where x is the interest rate per annum

So, 4 * (x/100) * $3,006 = ($3967.92 - $3006)

        x = 8%

So interest rate is 8% per annum

Jim began a 146​-mile bicycle trip to build up stamina for a triathlete competition.​ Unfortunately, his bicycle chain​ broke, so he finished the trip walking. The whole trip took 5 hours. If Jim walks at a rate of 4 miles per hour and rides at 40 miles per​ hour, find the amount of time he spent on the bicycle.

Answers

Answer:

3.5 hours

Step-by-step explanation:

Let us represent

The time spent walking as x

The time spent riding as y

Jim began a 146​-mile bicycle trip to build up stamina for a triathlete competition.​ Unfortunately, his bicycle chain​ broke, so he finished the trip walking. The whole trip took 5 hours.

Hence:

x + y = 5.... Equation 1

x = 5 - y

If Jim walks at a rate of 4 miles per hour and rides at 40 miles per​ hour,

The formula for Distance = Speed × time. Hence,

4 × x + 40 × y = 146 miles

4x + 40y = 146.... Equation 2

We substitute 5 - y for x in Equation 2

4(5 - y) + 40y = 146

20 - 4y + 40y = 146

Subtract 20 from both sides

20 - 20 - 4y + 40y = 146 - 20

- 4y + 40y = 146 - 20

36y = 126

y = 126/36

y = 3.5 hours

Since the time he spent raiding his bicycle is represented by "y", the amount of time he spent on the bicycle is 3.5 hours

if a person is selected at random from this group of 1,000 people, determine the probability that he or she does not wear eyeglasses while driving even though he or she needs to wear it.

Answers

The probability is 7/5.

A person is randomly selected from a group of 1000 people.

We have,

440 people use glasses and must wear them.

20 wear glasses but are not required to do so.

140 people who should wear glasses but don't

400 if you don't need to wear glasses, don't wear them.

Therefore, the probability that the person does not wear glasses while driving even though he or she needs to wear them is:

P ( he or she does not wear glasses and needs to wear them / Total number of people surveyed ) = 140 / 100

P = 14 / 10

P = 7 / 5

The probability that he or she drives without wearing eyeglasses despite the fact that they are required is 7 in 5.

In rhombus MNOP, side NO equals 45mm. What is the length of
OP
PM+MN

Answers

the length of side OP of rhombus is 45 mm and PM + MN is equal to 90 mm.

We are given a rhombus MNOP

We know that, a rhombus is a quadrilateral in which there are 4 sides and all the sides are equal.

We are given the length of the side NO as:

NO = 45 mm

Now, we need to find the length of side OP.

OP = 45 mm ( as NO = OP)

Also, we need to find PM + MN

PM + MN = NO + NO ( as PM = MN = NO )

= 2 NO

= 2 × 45 mm

= 90 mm

Therefore, we get that, the length of side OP of rhombus is 45 mm and PM + MN is equal to 90 mm.
