The data below shows numbers of hours mes Díaz volunteered at the library each month for eight months. 20,12,27,23,18,20,30,26. the mean of the data is 22 hours. What is the mean absolute deviation of the data?

Answer:

The range would be increased by 2

3,5,5,5,6

The range for that set would be 3.

If 8 were added... 3,5,5,5,6,8

The range for that set would be 5.

Answer: 2 2/5

Turn -1 3/5 into an Improper Fraction

Multiply -1×5 and get -5. Now add 3 and get -8.

-1 3/5 = -8/5

Do Keep Change Flip

Keep: -8/5

Change: ÷ into ×

Flip: -2/3 into -3/2

Multiply

-8/5×-3/2=12/5

Simplify

12/5 = 2 2/5

Answer:

2 2/5

Step-by-step explanation:

[tex] (2.3 \times 10^1) \times (7 \times 10^6)[/tex]

[tex](2.3 \times 7) \times (1 {0}^{1} \times {10}^{6} )[/tex]

[tex]16.1 \times {10}^{1 + 6} [/tex]

[tex]16.1 \times {10}^{7} [/tex]

The product of the given numbers is 1.61 × 10⁸.

Scientific notation is a way of writing a large number or small number with many digits in a simpler form using the power of 10.

For example, 30,000 can be written as 3 × 10⁴.

Given that,

We have to multiply the numbers (2.3 x 10¹) (7 x 10⁶).

The numbers in scientific notation uses exponents.

So we have to use the product rule of exponents here.

(2.3 x 10¹) (7 x 10⁶) = (2.3 × 7) × (10¹ x 10⁶)

                              = 16.1 × (10¹ x 10⁶)

We have the product rule, xᵃ . xᵇ = xᵃ⁺ᵇ

So the product is,

(2.3 x 10¹) (7 x 10⁶) = 16.1 × (10¹⁺⁶)

                              = 16.1 × 10⁷

                              = 1.61 × 10⁸

Hence the product in scientific notation is 1.61 × 10⁸.

Answer:

y = 2/3x +4

Step-by-step explanation:

The y intercept is where the line crosses the y axis

y intercept =4

We can find the slope using two points on the line

(0,4) and (3,6)

m = (y2-y1)/(x2-x1)

   = (6-4)/(3-0)

   = 2/3

The equation of a line in slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = 2/3x +4

Answer:

y = 2/3x +4

Step-by-step explanation:

let the 2 unknown be a and b

X = 0, Y = 4 -> 4 = 0*a+b -> b = 4

Y =0, X = -6  -> 0 = -6*a + 4 -> a = -4/-6 = 2/3

-> y = 2/3x +4

Please give me brainliest i hope you do well.!

Answer:

Step-by-step explanation:

The linear functions are the ones that can have at most 1 x-intercept. Specifically, slant lines and vertical lines have this characteristic.

The quadratic function doesn't have this characteristic because there are cases where it intercepts x-axis at two points (concave down).

Additionally, the exponential function doesn't have any x-intercept, because its range is restricted.

Therefore, the right asnwer is the linear function

The function that  could have at most 1 x-intercept is y = 2x + 4.

It is the function that can have at most 1 x-intercept. When slant lines and vertical lines should contain the attributes.

The quadratic function doesn't have this attribute since there are cases where it intercepts the x-axis at two points  that represent concave down.

Moreover, the exponential function doesn't have an x-intercept, since its range is restricted.

Therefore, it should be a linear function.

Answer:

Square root property

Step-by-step explanation:

The given equation is :

[tex]x^2+6=31[/tex]

We need to write the most appropriated technique to solve the above equation.

Subtracting both sides of the above equation by 6 such that,

[tex]x^2+6-6=31-6\\\\x^2=25[/tex]

Now taking square root on both sides we get :

[tex]x=\sqrt{25}[/tex]

The square root property is used here, such that the value of x is :
