Steve said that [5, 12) is the interval notation that represents the set of all real numbers greater than or equal to 5 and less than 12. Joe says that (5, 12] is correct interval notation. Who is correct and justify why?

Answers

Answer 1

Answer:

Steve was correct in his statement.

Step-by-step explanation:

According to standard notation, opening bracket ( [tex][[/tex] ) represents the lower bound of a set so that elements of the set are equal or greater than lower bound. In addition, closure parenthesis ( [tex])[/tex] ) represents the upper bound of a set so that element of the set are less than upper bound.

In consequence, Steve was correct in his statement.

A literary agent makes $30,000 a year plus 13% commission on the sales of her clients' books to publishers. The agent sold 4 books for $175,000 each for her
clients this year.
Find her total earnings.

Answers

Answer:

She made $121000.

Step-by-step explanation:

The money the agent sold was:

4*175000=700000 (dollars)

but she only gets 13% of this, so she earned:

700000*0.13=91000 (dollars)

She also makes $30000 per year, so the total income she earned was:

91000+30000=121000

A group of students collected old newspapers for a recycling project. The date shows the mass, in kilograms, of old newspapers collected by each student. What percent of students collected between 49 kilograms and 98 kilograms of newspapers?

Answers

The percentage of students who collected more than 49kg and less than 98kg of old newspapers is 54.54%

How to calculate the percentage of students who collected more than 49kg and less than 98kg?

To calculate the percentage of students who collected between 49kg and 98kg of old newspapers we must perform the following operations:

We must count how many students are in the range of 49kg to 98kg of old newspapers: 12 students out of 22 students.

100 ÷ 22 = 4.54%4.54 × 12 = 54.54%

So, those 12 students are equivalent to 54.54% of students.

Jane made $108 for 9 hours of work.At the same rate, how many hours would she have to work to make $216?
pls help

Answers

Answer:

18 hours

Step-by-step explanation:

$108 = 9 hours

$216 = x hours

we want to get to $216 from the original equation. one thing we can do to get there is to figure out what we need to multiply 108 by to get 216. to figure this out, we can calculate 216/108 = 2.

therefore, we can multiply both sides of the original equation by 2 to get

$216 = 9 * 2 hours = 18 hours as our answer

Answers

The probability of selecting a shower gel given item is scented must be the same as grabbing shower gel which is 42%.

What is probability?

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

Juanita has a storage closet at her shop with extra bottles of lotion and shower gel, some are scented and some are unscented.

If she reaches into the closet and grabs a bottle without looking, she has a 42% chance of grabbing a bottle of shower gel.

For the events "shower gel" and "scented" to be independent.

P(A|B) = P(A)

P(B|A) = P(B)

P(A∩B) = P(A) × P(B)

We know that the probability she selects a shower gel is 42%. Let this event be A. Then we have

P(shower | scented) = P(shower gel) = 42%

This must be true for the events to be independent.

Answers

Answer:

∠B = 58°

Step-by-step explanation:

∠A and ∠B are complementary.

-> ∠A + ∠B = 90°

-> 32° + ∠B = 90°

-> ∠B = 90° - 32°

-> ∠B = 58°

Answer:

<B = 58

Step-by-step explanation:

complementary angles are angles that sum up to 90°.

If A and B are angle when added will form 90°, to find B we follow the following steps

A + B = 90

if A = 32°,

32 + B = 90

collect like terms

B = 90 - 32

B = 58

that means

32 + 58 = 90

B = 58

7. Angle A and Angle B are congruent. The measure
of Angle A is 2x + 3. The measure of Angle B is 3x –
5. Solve for x. What is the measure of each Angle?

Answers

Answer:  x = 8, each angle is 19 degrees

=========================================

Work Shown:

angle A = angle B

2x+3 = 3x-5

3+5 = 3x-2x

8 = x

x = 8

angle A = 2x+3

angle A = 2*8+3

angle A = 16+3

angle A = 19

angle B = 3x-5

angle B = 3*8-5

angle B = 24-5

angle B = 19

Both angles are the same measure (19), which confirms our answer.

Answer:

X=8

Step-by-step explanation:

2x+3=3x-5. subtract 2x from both sides

3=x-5.  add 5 to both sides

3+5=x

x=8
