Answer:

250, 1250

Step-by-step explanation:

Since 10/2 = 50/ 10 = 5, the common ratio = 5    So the next term in the sequence is found by multiplying the last term by 5.  

Therefore, 50 x 5 = 250 and 250 x 5 = 1250. So, the next two terms in your sequence are 250 and 1250

Step-by-step explanation:

Given

y = 2x - 3

if x = - 4 Then

y = 2 * ( -4) - 3

= -8 - 3

= - 11

Hope it will help :)

The value of y when the value of x is equal to the negative number 4 is negative 11 (-11).

Unknown variables are used to find the unknown values of the problem using the algebraic expressions.

The expression for the variable x and y are given as,

[tex]y=2x-3[/tex]

The x value for the above expression is given as,

[tex]x=-4[/tex]

The value of y for the above value of x has to be found out.  Put the value of x in the given expression to find the value of variable y as,

[tex]y=2(-4)-3[/tex]

Solve it further as,

[tex]y=2(-4)-3\\y=-8-3\\y=-11[/tex]

Hence, the value of y when the value of x is equal to the negative number 4 is negative 11 (-11).

Answer:

10

Step-by-step explanation:

Use Pythagorean theorem,

hypotenuse² = 8² + 6²

                     = 64 + 36

                     = 100

hypotenuse = √100 = √(10*10)

Hypotenuse = 10

Answer:

[tex]E(x) = 4.56[/tex] --- Mean

[tex]s^2 = 1.0944[/tex] --- Variance

[tex]s = 1.0461[/tex] --- Standard Deviation

Step-by-step explanation:

See Comment for missing details

Given

[tex]p = 0.76[/tex] --- proportion

[tex]n = 6[/tex] -- sample

Solving (a): The mean; E(x)

This is calculated as:

[tex]E(x) = n * p[/tex]

Substitute values for n and p

[tex]E(x) = 6 * 0.76[/tex]

[tex]E(x) = 4.56[/tex]

Solving (b): The variance; s^2

This is calculated as:

[tex]s^2 = n*p*(1-p)[/tex]

Substitute values for n and p

[tex]s^2 = 6 * 0.76 * (1-0.76)[/tex]

[tex]s^2 = 6 * 0.76 * 0.24[/tex]

[tex]s^2 = 1.0944[/tex]

Solving (c): The standard deviation; s

This is calculated as:

[tex]s = \sqrt{s^2[/tex]

Substitute value for s^2

[tex]s = \sqrt{1.0944[/tex]

[tex]s = 1.0461[/tex]

Answer:

$0.40

Step-by-step explanation:

5.60/14 = .40

Answer:

the first term is a1

the 8th term is a8

the 4th term is a4

we have:

[tex]a8=a1.3^{7}\\\\<=>4374=a1.3^{7}\\\\<=>a1=2[/tex]

with a1 = 0,002 => a4 = a1.3³ = 2.27 =54

Step-by-step explanation:

The 4th term of the given geometric sequence is 54.

A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.

For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.

The nth term of a GP is given as a[tex]r^{n-1}[/tex]

As per the given,

Common ratio r = 3

8th term = 4374

a(3)⁸⁻¹ = 4374

a = 2

The 4th term will be as, 2 x (3)⁴⁻¹ = 54

Hence "The 4th term of the given geometric sequence is 54".

Answer:3:3:1

Step-by-step explanation:divide by 3

Answer:

angle 1= 30 degrees

angle 2= 120 degrees

angle 3= 30 degrees

Step-by-step explanation:

A triangle is equal to 180 degrees so first step is to subtract 120 to get the total of your two missing angles

180-120=60

and since your two missing angles are equal to each other you can divide by 2 and you get your two missing angles

60 / 2 = 30

If the points (1,3), (2, 1), (3,-1). (4.-3) lie on line k, then the slope of line k is -2

Option D is the correct choice

The points that lie on the line k are:

(1,3), (2, 1), (3,-1). (4.-3), and (5,-5).

We can find the slope of the line k by picking any two points on the line

The slope m of a line passing through the points (x₁, y₁) and (x₂, y₂) is given by the formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

On the line k, let us select the points (1,3) and (2, 1)

x₁ = 1, y₁ = 3, x₂ = 2, y₂ = 1

[tex]m = \frac{1-3}{2-1} \\\\m= \frac{-2}{1}\\\\m= -2[/tex]

Therefore, the slope of the line k is -2
