Answers
1. Distributive property 2(5k-6) = 10k -12
2. Add 10k-12-4= - 3K -39 which is 10k-16= - 3K -39
3. Add to both sides 10k -16 +16 = 10k, -3k-39 + 16 = -3k-24, 10k = -3k-24
4. Add to both sides with variable
10k + 3k = 13k, -3k-24+3k = -24

Consider the triangle below.
Determine the angle measure for the bottom two angles in order for the triangle to be classified as an isosceles triangle.
Answers
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

For the rhombus above, find the value of x. (leave decimal answer in the
hundredths place)
Answers
Answer:
iliterallydontknowfigureitoutyourself
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

[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]

The first three terms of a geometric sequence are as follows.
2, 10, 50
Find the next two terms of this sequence.
Answers
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
A cell phone provider offers a plan that costs $40 per month plus $0.20 per text message sent or received. A comparable plan costs $70 per month but offers unlimited text messaging.
Answers
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.
