Answer: I believe skewed right

Step-by-step explanation:

Their is a higher chance that it is skewed right because new workers will be coming in while long term workers will be retiring meaning that more workers will be toward the left side of the graph making anyone who has worked longer for the company possible outliers, which drags the graph to the right making it skewed right

Answer:

The data set would most likely be skewed right. The majority of employees would be paid an average amount, and only a few high-ranking employees would be paid significantly higher amounts. This data would result in a longer tail on the right with the majority of the data points on the left. In general, real-world situations are not symmetrical. This often occurs when one end of the range is bound by limits. In this case, the left side is bound by the minimum wage that must be paid to workers. On the right side, the president and other executives in the company probably don’t have a limit on their salaries.

Answer:2

Step-by-step explanation:

If you devide 58 by 7,you will get 8 as quotient..so 7×8=56..

So you will find (58-56)=2 as remainder..

Answer:

The Remainder of 58÷7 is 2

Step-by-step explanation:

The Remainder of a Division Operation is calculated by finding how many times the denominator goes into the numerator without going over and then subtracting that from the numerator.

For Example : [tex]58/7 = 8.28[/tex] ......which means 7 goes into 58 , 8 times.

Next we multiply 7*8 to give us 56.

Lastly, we subtract 58-56 to give us a remainder of 2.

Answer:

First, find a constant that can help you solve the equation. Note the equal sign, what you do to one side, you do to the other.

Remember, you are trying to do the following, changing: (note that y = constant)

x² - xy + y = (x - y)(x - y)

First, solve for the obvious answer. Plug in 0 to x:

2(0²) - 4(0) = 0

2(0) - 0 = 0

0 - 0 = 0

x = 0 is one of your answer choices.

Solve for the more complicated answer by doing what I put on the top:

2x² - 4x + 0 (+2) = 0 (+2)

2x² - 4x + 2 = 2

Divide 2 from both sides & all terms:

2(x² - 2x + 1) = 2(1)

x² - 2x + 1 = 1

Solve. Remember to set the equation = 0. Subtract 1 from both sides:

x² - 2x + 1 = 1

x² - 2x + 1 (-1) = 1 (-1)

x² - 2x + 0 = 0

x² - 2x = 0

Isolate the -2x. Add 2x to both sides.

x² - 2x (+2x) = 0 (+2x)

x² = 2x

Isolate the variable x. Divide x from both sides.

(x²)/x = (2x)/x

x = 2x/x

x = 2

x = 2 is your other answer choice.

x = 0, 2 is your answer.

~

Answer:

(0,2)

Step-by-step explanation:

x² - xy + y = (x - y)(x - y)

2(0²) - 4(0) = 0

2(0) - 0 = 0

0 - 0 = 0

2x² - 4x + 0 (+2) = 0 (+2)

2x² - 4x + 2 = 2

2(x² - 2x + 1) = 2(1)

x² - 2x + 1 = 1

x² - 2x + 1 = 1  

x² - 2x + 1 (-1) = 1 (-1)

x² - 2x + 0 = 0

x² - 2x = 0

x² - 2x (+2x) = 0 (+2x)

x² = 2x

(x²)/x = (2x)/x

x = 2x/x

x = 2

x = 0, 2 is your answer.

Answer:

24.997 = 25.00 (rounded off to 2 decimal figures)

Step-by-step explanation:

By observation, we can see that both straight lines are of equal length and that the angle between the lines is 90°. Hence we can conclude that this is a quadrant of a circle with radius, r =  7 cm.

length of the curved section

= 1/4 x circumference of the circle

= 1/4 x 2πr

= 1/4 x 2 x 3.142 x 7

= 10.997 cm²

HEnce circumference = 10.997 + 7 + 7 = 24.997 = 25.00 (rounded off to 2 decimal figures)

To work out the volume of a prism, you multiply the area of cross-section by the height (or length).

So for a cylinder, you work out the area of the circle and then multiply it by the height.

Area of circle (or cross-section) = π × radius²

                                                = π × 0.7²

                                                = 0.49π   m²

Now to get the volume of the cylinder, you times this area of the cross-section by the height of the cylinder:

Volume = 0.49π × 1.5

            = 2.3 m³  (accurate to 2 decimal places)

---------------------------------------------------------------

Answer:

The maximum volume of rainwater the cylinder can hold is:

2.3 m³

The maximum volume of rainwater will be "2.3 m³".

Given values are:

Height = 1.5 m

Diameter = 1.4 m

The Area of circle will be:

= [tex]\pi\times radius^2[/tex]

= [tex]\pi\times 0.7^2[/tex]

= [tex]0.49 \pi \ m^2[/tex]

hence,

The volume of cylinder be:

= [tex]0.49 \pi\times 1.5[/tex]

= [tex]2.3 \ m^3[/tex]

Thus the answer above is correct.

Answer:62

Step-by-step explanation:

The differance between 2 consecutive even number is 2...so if the first consecutive even number is x, then the next 4 consecutive even number will(x+2),(x+4),(x+6),(x+8)

So

X+(x+2)+(x+4)+(x+6)+(x+8)=310

5x+20=310

So,x=58

As the third number is (x+4)

Putting the value of x the final result comes(58+4)=62.

The log base 2 of [tex]\frac{1}{8}[/tex], i.e., [tex]\log_2 \frac{1}{8}[/tex] is -3.

In mathematics, the logarithm, denoted as "log," is an important mathematical function that represents the exponent to which a fixed base must be raised to obtain a given number. It is the inverse operation of exponentiation.

The logarithm function is typically written as [tex]log_b(x)[/tex], where x is the number for which we want to find the logarithm and b is the base. The base can be any positive number greater than 1, commonly used bases include 10 (logarithm to the base 10, often written as log(x)) and the mathematical constant e (natural logarithm, often written as ln(x)).

Answer:

The length of LM is 4.24

Step-by-step explanation:

* Lets revise the rules in the right angle triangle when we draw the

 perpendicular from the right angle to the hypotenuse

- In triangle ABC

# Angle B is a right angle

# The hypotenuse is AC

# BD ⊥ AC

∴ (AB)² = AD × AC

∴ (BC)² = CD × AC

∴ (BD)² = AD × CD

∴ BD × AC = AB × BC

* Lets use one of these rules to solve the problem

∵ Δ JLK is a right triangle

∵ ∠L is a right angle

∵ LM ⊥ JK

- We can find LM by one of the rule above

∵ JM = 3

∵ MK = 6

∵ (LM)² = JM × KM

∴ (LM)² = 3 × 6 = 18 ⇒ take a square root for both sides

∴ LM = √18 = 3√2 ≅ 4.24

Answer:

Gas Cost Per Month: Car A $21.43, Car B $31.58

Insurance Cost Per Month: Car A $125, Car B $83.33

Maintenance Cost Per Month: Car A $25, Car B $41.67

Total Cost Per Month: Car A $171.43, Car B $156.58

Step-by-step explanation:

Gas Cost Per Month:

It is a 20 mile round trip per day, so five days a week would be 100 miles. This means that you drive 400 miles to work in one month. So for Car A, 400/28 = 14.29 gallons. 14.29 gallons times $1.50 = $21.43 per month. For Car B, 400/19 = 21.05 gallons. 21.05 Gallons times $1.50 = $31.58 per month.

Insurance Cost Per Month:

Car A costs $1,500 to insure for one year. So if we take 1,500 and divide it by 12 we get $125 per month. Car B costs $1,000 to insure for one year. So taking 1,000 and dividing by 12 gives us roughly $83.33.

Maintenance Cost Per Month:

Car A costs $300 per year, so taking 300 and dividing by 12 gives us $25 per month. Car B costs $500 per year, so taking 500 and dividing by 12 gives us roughly $41.67 per month.

Total Cost Per Month:

Now all we need to do is add everything together. For Car A, we have $21.43 in gas, $125 in insurance, and $25 in maintenance. This gives a grand total of $171.43 per month. For Car B, we have $31.58 in gas, $83.33 in insurance, and $41.67 in maintenance, leaving a grand total of $156.58.

Hope this helps!

To compare the monthly operating costs of Car A and Car B, calculate and sum up the gas, insurance, and maintenance costs for each car. Car B, with a total monthly cost of $156.58, is less expensive to operate than Car A, which costs $171.43 per month.

To compare the cost of operating two different vehicles for one month, we need to calculate the monthly gas, insurance, and maintenance costs for each vehicle and then add them up to get the total monthly cost.

Calculating Costs for Car B

Comparing the total monthly costs, Car B is less expensive to operate than Car A.

Given that Noemi makes a bracelet that averages $0.60 per bead, we need to write an equation that models this average bead cost. This can be found by taking the total cost of the beads and dividing it by the number of beads used.

1. The total cost of the beads may be found by multiplying the price of each type of bead by the number used, and then adding these values together. Thus:

Total Cost = 0.75x + 3*0.3

= 0.75x + 0.9

2. Total number of beads = x + 3

3. Thus, the average cost is:

(0.75x + 0.9)/(x + 3)

4. Using the value of the average cost per bead given to us ($0.60), we can now write up the full equation:

0.6 = (0.75x + 0.9)/(x + 3)

The equation that represents Noemi's situation with the beads is [(0.75x) + (3*0.30)] / (x + 3) = 0.60, where x is the number of green beads. This equates the average cost per bead to the total cost of all the beads divided by the total number of beads.

Noemi strings together x green beads at $0.75 each with 3 blue beads at $0.30 each and she makes a bracelet that averages $0.60 per bead. We can therefore write the situation as an equation where the total cost of the beads is equal to the average cost per bead times the total number of beads.

That is,[tex][(0.75x) + (3*0.30)] / (x + 3) = 0.60[/tex]

This equation represents the total cost of the green and blue beads (0.75x + 0.90), divided by the total number of beads (x + 3), is equal to the average cost per bead ($0.60). You can solve this equation for x to find the number of green beads Noemi used in her bracelet.

Answer:

x = 5

Step-by-step explanation:

The formula for the gradient is given by:

m = (y2 - y1)/(x2 - x1), where two points (x1, y1) and (x2, y2) are given.

Thus if we have a gradient of 2.5 and two points (3, 8) and (x, 13), we can substitute this into the above formula for the gradient to get:

2.5 = (13 - 8)/(x - 3)

2.5(x - 3) = 5 (Multiply both sides by (x - 3))

x - 3 = 2 (Divide both sides by 2.5)

x = 5 (Add 3 to both sides)

Thus, the value of x is 5.

First multiply 2 to both sides to isolate q. Since 2 is being divided by q, multiplication (the opposite of division) will cancel 2 out (in this case it will make 2 one) from the left side and bring it over to the right side.

[tex]\frac{q}{2}[/tex] × 2 < 2 × 2

q < 4

For the graph will you have a empty or colored in circle?

If the symbol is ≥ or ≤ then the circle will be colored in. This represents that the number the circle is on is included.

If the symbol is > or < then the circle will be empty. This represents that the number the circle is on is NOT included.

Which direction will the ray go?

If the variable is LESS then the number then the arrow will go to the left of the circle.

If the variable is MORE then the number then the arrow will go to the right of the circle.

In this case your inequality is:

q < 4

aka q is less then four

This means that the graph will have an empty circle and the arrow will go to the left of 4. (look at image below)

Possible pairs are 1, -5; -1, 5;

By trial and error, you will find that 1 and -5 work:

1 × (-5) = -5 and 1 - 5= -4

x² - 4x - 8 = (x + 1)(x - 5)

(c) Solve the quadratic

[tex]\begin{array}{rlcrl}x+ 1 & =0 & \qquad & x - 5 & =0\\x & = -1 & \qquad & x & = 5\\\end{array}\\\text{The solution to the system of equations is }\boxed{\mathbf{x = -1; x = 5}}[/tex]

the solutions to the equations is (-1, -5) and (5, 7)
