Answer: 8.3

Step-by-step explanation:

To find the variance, you want to find the mean of the data.

[tex]\frac{3+3+8+1+9+6}{6} =5[/tex]

Now that we have the mean, we find the difference between each data point and the mean.

3-5=-2

3-5=-2

8-5=3

1-5=-4

9-5=4

6-5=1

With the difference, you square each and find the average.

(-2)²=4

(-2)²=4

3²=9

(-4)²=16

4²=16

1²=1

[tex]\frac{4+4+9+16+16+1}{6} =\frac{25}{3}[/tex]

The variance is 8.3.

Answer:

B. 33.6 cm

Step-by-step explanation:

To find determine the length of an arc that subtends an angle of 2.8 radians at the centre of a circle with radius 12 cm, we will follow the steps below;

First write down the formula for calculating length of an arc

If the angle is measured in degree, then the formula for calculating the length of an arc is :

length of an arc = Ф/360  ×  2πr

but if the angle is measured in radians, then the formula for calculating length of an arc will be:

length of an arc = r Ф

where r is the radius    and Ф is the central angle in radians

In the case of the question given to us, the angle is given in radians, so we will use the second formula

angle Ф = 2.8

radius = 12 cm

length of an arc = r Ф

                           =12 × 2.8

                           =33.6

Length of the arc = 33.6 cm

PART 1:

Possible roots by noticing the coefficient of first term:

x = 1, -1

PART 2:

   1   0  -4  0

The remainder is zero, hence one factor is (x-1)

PART 3:

PART 4:

Answer: 31%

Step-by-step explanation: We can change a decimal to a percent by moving the decimal point two places to the right.

So in this problem, to change 0.31 to a percent, we

move the decimal point two places to the right.

So we have 31%.

So 0.31 can be written as 31%.

This should make sense because 0.31 can be read

as 31 hundredths or 31 over 100 which is 31%

Answer:

31%

Step-by-step explanation:

To change 0.31 into a percent, you must move the decimal to the right two times.

When we move the decimal in 0.31, it will look like this:

03.1

Now, if we move the decimal again, it will look like this but will be equivalent to 31%:

031. = 31%

Another step-by-step explanation:

You can also write 0.31 as a fraction which is:

31/100 = 31%

It will still be equal to 31%.

Therefore, 0.31 as a percent is equal to 31%.

Answer:

2728.11m

Step-by-step explanation:

The height of the plane is 1020m

The airport makes an angle of elevation of 20.50° with the plane

The distance of the plane from the airport = ?

See attached document for better illustration of the position of the plane and airport

Using SOHCAHTOA,

tanΘ = opposite/ adjacent

θ = 20.50°

opposite = 1020m

adjacent = ? = x

Tanθ = opposite/ adjacent

Tan20.50 = 1020 / x

X = 1020 / tan20.50

X = 1020 / 0.37388

X = 2728.11m

The distance of the plane from the airport is 2728.11m

Answer:

A

Step-by-step explanation:

Answer:

Take a look at explanation below;

Step-by-step explanation:

See attachment( s ) below;

The value of x and y angles on the given lines are x=35 degrees and y=125 degrees.

A line is a collection of points which joins the two points on the surface.

If we consider the angles which are linear pair, we found that

55 +y=180 because they are on a straight line.

From the figure wee found that x+55+90=180 because they are on a straight line.

solving the second equation we will get , x=180-145=35

solving the first equation we will get , y=180-55=125.

Hence the value of x angle is 35 degrees and the value of y angle is 125 degrees.

Step-by-step explanation:

Just remeber C then D Like a CD, because a cd is a circle XD hope I help

Answer: A is the correct answer .

Start with the last two choices .

You have x+ 5 and × - 5 in the square root .

A square root can never be negative .

That means that the lowest value of y can have in the last two choices is 0 .

Now range doesn't include -4.

Now look at choice B .

sqrt (x) is at least 0.

Then you add 5 .

The range doesn't include -4.

Now look at choice A .

sqrt (x) is at lest 0 .

Now ,you subract 5 .

The lowest value y can have is -5 . That includes -4.

Choice A is the answer .

y will be at least 5

Step-by-step explanation:

The common difference in the arithmetic sequence is 2.5

Arithmetic sequence is a sequence in which the differences between consecutive terms are always same.

Example : 2, 5, 8, 11, ..... is an arithmetic sequence where the common difference is 3.

Formula of arithmetic sequence is [tex]a_{n} =a_{1}+(n-1)d[/tex] ,

where [tex]a_{n}[/tex]= [tex]n^{th}[/tex] term in the sequence,

[tex]a_{1}[/tex]= [tex]1^{st}[/tex] term in the sequence,

d = common difference between terms

Given, [tex]a_{1}[/tex] = 16 and [tex]a_{9}[/tex] = 36

Let, d be the common difference.

∴ From the formula of arithmetic sequence,

   [tex]a_{9} =a_{1}+(9-1)d[/tex]

⇒ 36 = 16+8d

⇒ 36-16=8d

⇒ 20=8d

⇒ d = 20/8

⇒ d = 5/2 = 2.5

Hence, The common difference is 2.5

Answer:

Step-by-step explanation:

Answer:

z = 4°

Solution:

Given EFGH is an isosceles trapezoid.

By the property of isosceles trapezoid, non-parallel sides are congruent.

⇒ GH = EF

Angles opposite to equal sides are congruent.

∠H ≅ ∠G

m∠H = m∠G

105° = 3z + 93°

Subtract 93° from both sides, we get

12° = 3z

Divide by 3 on both sides, we get

4° = z

Switch the sides.

z = 4°

Hence the value of x is 4°.

[tex]x = \frac{9}{2}[/tex]

Step-by-step explanation:

x - 2 (x - [tex]\frac{3x}{2}[/tex]) = 2 (4 - x) + 10

x − 2 × [tex]\frac{-x}{2}[/tex] =2(4−x)+10

x−(−x)=2(4−x)+10

x+x=2(4−x)+10

2x=2(4−x)+10

2x=8−2x+10

2x=−2x+18

2x+2x=18

4x=18

[tex]x = \frac{18}{4}[/tex]

[tex]x = \frac{9}{2}[/tex]
