Answer:

30-3=27

Step-by-step explanation:

Finding the deviation of this is pretty simple

1) Find the mean

By finding the mean, you add the numbers together, and divide the sum by the number of numbers, in this case there are 10 numbers, so divide by 10

2) Subtract the data value, basically adding all of the numbers up, and subtracting it by 3, the mean.

the number sets:

3,1,5,5,2,3,2,3,4,2

mean=

30/10

by finding this, i added the numbers and divided it by the amount of numbers.

This would equal to 3.

Now, all you have to do is subtract 3 from the data value

The data value is 30, subtracted by 3 would be 27

Sorry if I am wrong, I am just 4th grade :(

I am sure I am right, but in case it IS wrong, use the formula in the explanation :)

I might've gotten it wrong because the numbers were unclear, but I think it is correct:)

3 - 2 = 1

3 - 3 =0

3 - 2 = 1

3 - 3 = 0

3 - 4 = 1

3 - 2 = 1

Solution given:

x=2

y=3

The requried solution to the pair of equations is (2, 3).

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,

Part A: To solve the pair of equations graphically, we need to plot both equations on the same coordinate plane. To plot each equation, we can use the slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.

For the equation y = 2x - 1, the slope is 2 and the y-intercept is -1. For the equation y = 4x - 5, the slope is 4 and the y-intercept is -5. We can plot these two lines on the same coordinate plane and find their intersection point.

Part B: We can find this point by setting the two equations equal to each other and solving for x:

2x - 1 = 4x - 5

Subtracting 2x from both sides, we get:

-1 = 2x - 5

Adding 5 to both sides, we get:

4 = 2x

Dividing by 2, we get:

x = 2

Now that we have found the value of x, we can substitute it into either equation to find the value of y. Using the equation y = 2x - 1, we get:

y = 2(2) - 1

y = 3

Therefore, the solution to the pair of equations is (2, 3).

Step-by-step explanation:

Answer: 336.14 cm²

Step-by-step explanation:

To find the area of the rectangle after being cut, we want to find the area of the two semicircles and subtract it from the area of the rectangle. The area of the rectangle is just base times height, or 35cm times 14cm = 490cm² . Since there are two semicircles with the same diameter, we can just solve for the area of a circle and subtract it. To find the area of the circle, we need the radius, which we get by dividing the diameter by 2. After that, we calculate the radius to be 7cm, squared and multiplied by 3.14 (area of a circle) to get 153.86 cm². Subtract the areas, and we get 490 - 153.86 = 336.14 cm²

Answer:

B.

Step-by-step explanation:

B- 10 + 15 = 25 (More than the 3rd side) ✅

C- 9 + 11 = 20 (Cannot be less than the 3rd side)

D- 7 + 6 = 13 (Cannot be less than the 3rd side)

Focus on triangle QAC. We're given that CQ = CA, which in turn means the angles opposite these sides (angles A and Q in that order) are congruent. This is one property of isosceles triangles. Let's make x equal to each of these angles.

With inscribed angle QAC = x, it doubles to 2x which is the measure of minor arc BC (inscribed angle theorem). Minor arc AB is also 2x, since we're told these two arcs have the same measure.

If minor arc BC = 2x, then cutting this in half leads to x again, which points to inscribed angle BDC equal to x. Notice how inscribed angles QAC and BDC subtend the same minor arc BC. Through similar logic, inscribed angle BDA is also x.

In short: angle BDC = angle BDA = x. This leads to angle ADC = 2x. We'll use this later.

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

Let's go back to triangle QAC. The angles A and Q are both x each. The missing angle C is...

Q+A+C = 180

x+x+C = 180

2x+C = 180

C = 180-2x

Making angle QCA equal to 180-2x

Angle ACD is supplementary to this.

So,

angle ACD = 180-(angle QCA) = 180-(180-2x) = 2x. We'll use this later as well.

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

The first section concluded with angle ADC = 2x, while the second section concluded with angle ACD = 2x

For triangle ACD, the bottom angles C and D are both 2x. This is sufficient evidence to show that triangle ACD is isosceles. Furthermore, it means AC = AD, which are the sides opposite angles D and C respectively.

Answer:

x ≈ 20.31

Step-by-step explanation:

By applying tangent rule in the given right triangle,

tan(55°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

Measure of the opposite side = 29 units

Measure of the adjacent side = x

Substitute these values in the expression,

tan(55) = [tex]\frac{29}{x}[/tex]

x = [tex]\frac{29}{tan(55)}[/tex]

x = 20.306

x ≈ 20.31

Answer:

Interval $11 - $15 = 0.2

Step-by-step explanation:

Sum of frequency, Σf = (8+6+4+2+4+6+2) = 32

Relative frequency = f / Σf

Interval :

1 - 5 = 8 / 20 = 0.4

6 - 10 = 6 / 20 = 0.3

11 - 15 = 4 / 20 = 0.2

16 - 20 = 2 / 20 = 0.1

21 - 25 = 4 / 20 = 0.2

26 - 30 = 6 / 20 = 0.3

31 - 35 = 2 / 20 = 0.1

The mean absolute deviation of the number of points scored is 4.4.

The mean deviation is used to calculate how far the values fall from the mean of the data set.

Here, Given data is 31, 20, 27, 19, 28

Mean = Sum of all data / number of terms

         = (31 + 20 + 27 + 19 + 28)/5

         = 125/5

         = 25

Then, the deviation will be 6, 5, 2, 6, 3

Mean Deviation = Sum of Deviation / Total number of deviation

                          = ( 6 + 5 + 2 + 6 + 3) / 5

                          = 22 / 5

                          = 4.4

Thus, the mean absolute deviation of the number of points scored is 4.4.

Answer:

Mark will make $80 if he works an eight-hour shift.

Step-by-step explanation:

For every six hour shift he works, Mark makes $60

This implies that for every hour, he makes $10 ($60/6)

Therefore, for working an eight-hour shift, Mark will make $80 ($10 * 8) or ($60/6 * 8).

We can conclude that Mark's employer pays him $10 per hour.

This hourly rate can be used to work out how much Mark will earn if he works for a month or a year, as the case may be.

Answer:

Yes, 9^2+40^2=41^2

Step-by-step explanation:

From the Pythagoras’ theorem, the square of the hypotenuse of a right triangle equals the sum of the squares of the two other sides

From what we have , the side lengths are 9, 40 and 41

As we can see, 41 is the longest side length and that makes it the hypotenuse

The square of the two other sides is 40^2 + 9^2 = 1,681

Also, 41^2 = 1,681

As we can see, the sum of the squares equal the square of the hypotenuse

Since this follows the theorem, we can conclude that the triangle is a right triangle

Answer:

C, Yes, 92+402=412.

Step-by-step explanation:

Area of a circle formula: area = pi x r^2

R is the radius which is 1/2 the diameter.

The diameter is 4 yards so the radius is 4/2 = 2 yards.

Area = 3.14 x 2^2

Area = 12.56 square yards.
