Answer:

x = 19.25

Step-by-step explanation:

The diagonal of a rhombus bisects opposite angles and opposite angles are congruent.  

So, 2x - 1 is the measure of the third angle of the triangle

Therefore, 2x - 1 + 2x - 1 + 4x + 28 = 180 since the sum of the measures of the angles of a triangle is 180

8x + 26 = 180

8x = 154

x = 19.25

Answer:

2

Step-by-step explanation:

When it comes to like terms, they have to end with the same symbol A.K.A variables, exponents, and numbers.

1 + 9 + 3u

There are two terms, constants and variables, constant being 1 and 9 while variable being 3u.

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

Answer:

x=51/5

Step-by-step explanation:

Add 61 on both sides

You'll have 5x=51

So now 51/5 is your answer.

Answer:

16/5

Step-by-step explanation:

|5x - 6| = -10

5x -6 = 10

5x = 10+6 = 16

x = 16/5

Answer:

50°

Step-by-step explanation:

As we know that the opposite angles of parallelogram are equal so

< ADC = < ABC

< ABC = 38° +12°

< ABC = 50°

Step-by-step explanation:

y=3(4)²+1

 =48+1

 =49

Answer:

The output is 49

Step-by-step explanation:

If the input is 4, then x = 4.

Replace x with 4 and you have the equation:

3(4)^2 + 1 = 49

Because Y is the output, and Y = 49, the output is 49

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:

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

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:

For, 250 messages the plans cost the same. Under 250 messages, plan A is cheaper.

Step-by-step explanation:

Giving the following information:

Plan A:

Fixed costs= $40

Variable cost= $0.2

Plan B:

Fixed cost= $40

I assume that we have to determine the indifference point, where the two plans cost the same.

First, we need to establish the total cost equations

Plan A= 20 + 0.2x

Plan B= 70

x= number of messages

Now, we equal both formulas and isolate x:

20 + 0.2x = 70

0.2x= 50

x= 250

For, 250 messages the plans cost the same. Under 250 messages, plan A is cheaper.

Answer:

The slope of the line is [tex]\frac{5}{2}[/tex]

Step-by-step explanation:

Hi there!

We are given the following points: (-2, 4) and (0, 9)

We want to find the slope (m) of these 2 lines, and the problem asks us to use the slope formula

The slope formula is given as [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points

We have everything we need to calculate the slope, but let's label the values of the points to avoid any confusion.

[tex]x_1=-2\\y_1=4\\x_2=0\\y_2=9[/tex]

Now substitute these values into the formula to find the slope.

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

m=[tex]\frac{9-4}{0--2}[/tex]

Simplify.

m=[tex]\frac{9-4}{0+2}[/tex]

Add (or subtract) the numbers together

m=[tex]\frac{5}{2}[/tex]

The slope of the line is [tex]\frac{5}{2}[/tex]

Hope this helps!
