Answer:

6^2 = 36

Step-by-step explanation:

The number that best approximates the square of 6 is 36, its actual value. The point so labelled is the appropriate point on the number line.

7.7 is the point on the number line is the best approximation for √59

A number system is defined as a system of writing to express numbers.

A number line is a picture of a graduated straight line that serves as visual representation of the real numbers.

Approximation or approximate numbers can be defined as a value that is similar to the other value but not exactly equal to it.

We need to find the approximation of √59

We have given √59

We need to remove the radical

=7.681=7.7=8

We can place the dot on 7.7 of the number line.

Hence 7.7 is the point on the number line is the best approximation for √59

Answer:

Approximately 0.51

Step-by-step explanation:

If events A and B are independent, then P(A and B) = P(A)*P(B) is a true equation.

We're given the following

     P(A) = 0.65

     P(A and B) = 0.33

So,

P(A and B) = P(A)*P(B)

0.33 = 0.65*P(B)

P(B) = 0.33/0.65

P(B) = 0.5076923076923

which is approximate. When we round to 2 decimal places, we get 0.51

Answer:

Step-by-step explanation:

Using h and b to represent the prices of hockey and basketball tickets, respectively, the two purchases are ...

  2h +b = 173.01

  h +2b = 162.99

Subtracting the second equation from twice the first gives ...

  2(2h +b) -(h +2b) = 2(173.01) -(162.99)

  3h = 183.03

  h = 61.01

Substituting that into the first equation, we can solve for b:

  b = 173.01 -2h = 173.01 -2(61.01)

  b = 50.99

The average cost of an NHL ticket was $61.01.

The average cost of an NBA ticket was $50.99.

Answer:

A service business because it lists the products for online purchase

Step-by-step explanation:

Adele does not manufacture the clothes that she sells, but rather acquires and resells them electronically. Therefore, she provides a clothing sales service, forming part of the third sector of the economy. If, on the other hand, she manufactured the clothes, her business would be manufacturing and, therefore, she would be part of the second sector of the economy, as she would be carrying out a type of industry.

Answer:

a merchandising business because it resells clothes at retail prices

Step-by-step explanation:

This is a merchandising business because Adele buys clothes at one price and resells them at a higher retail price.

His salary for 40 hours per week with an hourly rate is hours x the rate:

40 hours x $22 per hour = $880 per week.

If he is paid commission, to make the same , he needs to make $880 iin commissions.

The commission rate is 4%, to find how much sales is needed divide the amount he needs to make ( $880) by the rate:

880/ 4% = 880/ 0.04 = $22,000

He needs to sell $22,000

Answer:

(a) 7 essays and 29 multiple questions

(b) Your friend is incorrect

Step-by-step explanation:

Represent multiple choice with M and essay with E.

So:

[tex]M + E= 36[/tex] --- Number of questions

[tex]2M + 6E = 100[/tex] --- Points

Solving (a): Number of question of each type.

Make E the subject of formula in [tex]M + E= 36[/tex]

[tex]E = 36 - M[/tex]

Substitute 36 - M for E in [tex]2M + 6E = 100[/tex]

[tex]2M + 6(36 - M) = 100[/tex]

[tex]2M + 216 - 6M = 100[/tex]

Collect Like Terms

[tex]2M - 6M = 100 - 216[/tex]

[tex]-4M = - 116[/tex]

Divide both sides by -4

[tex]M = \frac{-116}{-4}[/tex]

[tex]M = 29[/tex]

Substitute 29 for M in [tex]E = 36 - M[/tex]

[tex]E = 36 - 29[/tex]

[tex]E = 7[/tex]

Solving (b): Can the multiple questions worth 4 points each?

It is not possible.

See explanation.

If multiple question worth 4 points each, then

[tex]2M + 6E = 100[/tex] would be:

[tex]4M + xE = 100[/tex]

Where x represents the number of points for essay questions.

Substitute 7 for E and 29 for M.

[tex]4 * 29 + x * 7 = 100[/tex]

[tex]116 + 7x = 100[/tex]

Subtract 116 from both sides

[tex]116-116 + 7x = 100 -116[/tex]

[tex]7x = 100-116[/tex]

[tex]7x = -16[/tex]

Make x the subject

[tex]x = -\frac{16}{7}[/tex]

Since the essay question can not have worth negative points.

Then, it is impossible to have the multiple questions worth 4 points

Your friend is incorrect.

The test contained 29 multiple choice questions and 7 essay questions.

Let x represent the number of multiple questions and y represent the number of essay questions.

Given that there are a total of 36 questions, hence:

x + y = 36    (1)

Also, the test is worth a total of 100 points, hence:

2x + 6y = 100   (2)

Solving equation 1 and 2 simultaneously gives:

x = 29, y = 7

Therefore the test contained 29 multiple choice questions and 7 essay questions.

Answer:

25% probability that you complete the course

75% probability that you do not complete the course

Step-by-step explanation:

If there are a total of 4 individuals entering the race and only one is able to complete the course then the probability that you will complete the course would be

1/4 = 0.25 or 25%

This is because you only represent 1 out of the 4 total participants. The opposite would be the case to calculate the probability that you will not complete the course since there are three other candidates with that could have completed it, therefore...

3/4 = 0.75 or 75%

Answer:

1 hour and 15 minutes

Step-by-step explanation:

For the hours he had slept the last is around 7 hours and 15 minutes and the one where he slept the most is around 8 hours and 30 minutes.  Subtract these two numbers in which your answer is that Tom slept for 1 hour and 15 minutes more than the one where he slept the least.

Answer:

2 hours

Step-by-step explanation:

Answer:

a = 6 and b = -1.

Step-by-step explanation:

To find the maximum value of y = -x²+ ax + b we differentiate it with respect to x to find the value of x at which it is maximum.

So dy/dx = d(-x²+ ax + b)/dx = -2x + a

we equate it to zero.

-2x + a = 0

-2x = -a

a = 2x

Now, given that x = 3 at the maximum value,

a = 2x = 2(3) = 6

Also, substituting y = 8 and x = 3 into y, we have

y = -x²+ ax + b

8 = -(3)²+ a(3) + b

8 = -9 + 3a + b

3a + b = 8 + 9

3a + b = 17

So, b = 17 - 3a

substituting a = 6, we have

b = 17 - 3(6)

b = 17 - 18

b = -1

So, a = 6 and b = -1.

Answer:

Step-by-step explanation:

Since the values on both sides are different, hence the  the system of inequalities have NO solutions

Inequalities are equation that does not include only the equal sign.

Given the following inequalities

y > - 1/3x+5 and y< - 1/3 x -1

In order to determine whether the equations have a solution, we need to equate both expressions and solve

Equate

-1/3x + 5 = -1/3x - 1

-1/3x + 1/3x  = -1 - 5

0x = -6

Since the values on both sides are different, hence the  the system of inequalities have NO solutions
