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.
Suppose that the probability that your mail is delivered before 2 pm. 90. What is the probability that your mail will be delivered before 2 pm for two consecutive days? Give your answer as a decimal.
Thank you!
Answers
Answer:
Step-by-step explanation:
1. The probability that your mail is delivered before 2 pm is 0.9, so the probability that the mail is delivered at 2 pm or after 2 pm (so not before 2 pm) is 1-0.9=0.1.
Remark: 0.9=9/10=90/100=90%, and 0.1 is 10%

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

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

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
How would u solve for x
8x-2=-9+7x
Answers
x = -7
8x-7x = -9+2

[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]

Colton has 888 comedy movies, 666 action movies, 555 fantasy movies, and 111 drama movie on his list of favorite movies. For every 555 movies on the list, there are 222 \_\_\_\_____\_, \_, \_, \_ movies.
Answers
Answer: Comedy
Step-by-step explanation:
Find out the percentages of each of the movies. First find the total quantity.
= 888 + 666 + 555 + 111
= 2,220 movies
Comedy = 888/2,220 * 100% = 40%
Action = 666 / 2,220 * 100% = 30%
Fantasy = 555/2,220 * 100% = 25%
Drama = 111/ 2,220 * 100% = 5%
222 movies out of 555 is:
= 222 / 555 * 100%
= 40%
222 movies out of 555 movies will therefore be comedy.
Answer:
222/555 are comedy

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
The enrollment at a university increased from 1,000 students to 6,000 students over a 6-year period. What was the percent increase in enrollment over that time period?
Answers
Answer: 500%
Step-by-step explanation:
The percent increase is calculated as:
= (New number of students - Old number of students) / Old number of students * 100%
= (6,000 - 1,000) / 1,000 * 100%
= 5 * 100%
