Answer:

The standard deviation of the given data set

 σ =  2.135

Step-by-step explanation:

Step(i):-

Given numbers are 4 2 8 5 7

Mean of the numbers

 [tex]= \frac{4+2+8+5+7}{5}[/tex]

= 5.2

The mean of the numbers (μ) = 5.2

Step(ii):-

x        :    4         2       8        5         7

x-μ     :   -1.2   -3.2     2.8    -0.2     1.8

(x-μ)² :   1.44    10.24  7.84  0.04    3.24

The standard deviation of the given data

            σ = √Σ( x-μ)² / N

           σ  = [tex]\sqrt{ \frac{1.44+10.24+7.84+0.04+3.24}{5}}[/tex]

            σ =  2.135

Answer:

6

Step-by-step explanation:

We have two fractions and are asked to find the answer if they both are divided.

3/5 and 1/10.

When we divide fractions, we need to follow KCF

KEEP - Keep the fractions

CHANGE - Change the division sign to a multiplication sign

FLIP - Flip the second fraction

Follow :

KEEP :

3/5 / 1/10

CHANGE :

3/5 * 1/10

FLIP :

3/5 * 10/1

Now we need to multiply, which is simple because it's multiplying across :

[tex]\frac{3*10}{5*1}[/tex]

30/5

Simplify by dividing the numerator and denominator by 5 :

[tex]\frac{30/5}{5/5} = \frac{6}{1}[/tex]

Divide the numerator by denominator :

[tex]\frac{6}{1} = 6[/tex]

Answer:

x=-5

Step-by-step explanation:

First, you have to cross multiply.

2*2x+3     1*3x+1

4x+6=3x+1

Then, you subtract 3x from both sides.

4x+6=3x+1

-3x     -3x

x+6=1

Next, you subtract 6 from both sides.

x+6=1

    -6  -6

x=-5

Answer:

x = -5 (process below)

Step-by-step explanation:

1) To solve this easily, you can cross multiply. Multiply the numerator of the first fraction with the denominator of the second fraction, and multiply the denominator of the first fraction with the numerator of the second fraction:

[tex]\frac{2}{3x+1} = \frac{1}{2x+3} \\2(2x +3) = 1(3x + 1)\\4x + 6 = 3x + 1[/tex]

2) Next, isolate x to find its values. Subtract both sides by 3x.

[tex]4x + 6 = 3x +1\\x + 6 = 1[/tex]

3) Finally, subtract both sides by 6.

[tex]x + 6 = 1 \\x = -5[/tex]

Answer:

$844496111

Step-by-step explanation:

Size, n = 9

Initial average = 65000

Average = total sum / size

Initial Sum = 9 * 65000

Initial sum = $585,000

New average = ((585,000 - 120,000 + 7,600,000,000)) / 9

New average =

$7600465000 / 9

= $844496111. 11

= $844496111

Answer:

Option 3 is right

Start at the origin. Move 3 and one-half units down because the x-coordinate is Negative 3 and one-half. Negative 3 and one-half is between -3 and -4. Move 2 units right because the y-coordinate is -2.

Answer: In 1225 miles, there are ≈7.7629 x 10⁷ inches

Step-by-step explanation:

Given that

1 inch≈ 1.578 × 10 -5 miles.

?? inches   =      1225 miles

Solving  

(1,225 x 1 inch) / 1.578 x 10 ⁻⁵)

=77,629,911 changing to scientific notation becomes 7.7629 x 10⁷ inches

Answer:

∴ m∠KIJ = 18°  and   m∠HIJ = 50°

Thus, option a is correct.

Step-by-step explanation:

From the figure, it is clear that:

m∠KIH = m∠HIJ + m∠KIJ

Given

now substituting m∠KIH = 68°, m∠KIJ = (2x + 6)° and m∠HIJ = (9x - 4)° in the equation

m∠KIH = m∠HIJ + m∠KIJ

68° = (2x + 6)° + (9x - 4)°

switch sides

[tex]\left(2x+6\right)+\left(9x-4\right)=68[/tex]

Group like terms

[tex]2x+9x+6-4=68[/tex]

[tex]11x+2=68[/tex]

Subtract 2 from both sides

[tex]11x+2-2=68-2[/tex]

Simplify

[tex]11x=66[/tex]

Divide both sides by 11

[tex]\frac{11x}{11}=\frac{66}{11}[/tex]

Simplify

[tex]x=6[/tex]

Hence, the value of x = 6

Therefore,

m∠KIJ = (2x + 6)° = 2(6) + 6 = 12 + 6 = 18°

m∠HIJ = (9x - 4)° = 9(6) - 4 = 54 - 4 = 50°

∴ m∠KIJ = 18°  and   m∠HIJ = 50°

Thus, option a is correct.

Answer:

-4x + 12

Step-by-step explanation:

2(x+6)-6x

2x + 12 - 6x

combine llike terms

2x - 6x = -4x

-4x + 12

Answer:

2(x+6)-6x=-4x+12

Step-by-step explanation:

So how I got that was I expanded 2(x+6): 2x+12 so I got 2x+12-6x

I simplified 2x+12-6x and I got -4x+12

Answer:

D

Step-by-step explanation:

This is because if u subsitute x with 17, 17x5 is 85 and 85+95= 180

[tex]\color{plum}\tt\bold{(D) \: 17}[/tex]

Given :

▪︎Angle (5x)° and angle 95° are supplementary angles.

Which means :

[tex] = \tt5x + 95 = 180[/tex]

[tex] = \tt5x = 180 - 95[/tex]

[tex] = \tt5x = 85[/tex]

[tex] \hookrightarrow\tt \color{plum}x = 17[/tex]

Thus, the value of x = 17

Let us check whether or not we have found out the correct value of x by placing 17 in the place of x:

[tex] =\tt5 \times 17 + 95 = 180[/tex]

[tex] =\tt 85 + 95 = 180[/tex]

[tex] =\tt 180 = 180[/tex]

Since the sum of both angles is equivalent to 180[85+95=180], we can conclude that we have found out the correct value of x.

Therefore, the correct option is (D) 17

Answer:

the first one x = -2

Step-by-step explanation:

Let's solve your equation step-by-step.

4x−6=10x−3

Step 1: Subtract 10x from both sides.

4x−6−10x=10x−3−10x

−6x−6=−3

Step 2: Add 6 to both sides.

−6x−6+6=−3+6

−6x=3

Step 3: Divide both sides by -6.

Answer:

x = -1/2

Step-by-step explanation:

4x - 6 = 10x - 3

    +6           +6

  4x = 10x + 3

-10x   -10x

-6x = 3

3 / -6 = -1/2
