Answer:
y= 1/4x +1
Step-by-step explanation:
First I needed to find the y-intercept which means I have to get the slope to cross (0,?). Using the point of intersect and slope, I was able to move 4 spaces to the right and 1 space up 2 time. If you do the math 4x2=8 1x2=2.
-8+8=0 which is our x coordinate
-1+2= 1 which is our Y coordinate
(0,1) + 1/4x= y= 1/4x +1

A chain letter starts when a person sends a letter to five others. Each person who receives the letter either sends it to five other people who have never received it or does not send it to anyone. Suppose that 10,000 people send out the letter before the chain ends and that no one receives more than one letter. How many people receive the letter, and how many do not send it out?

Step-by-step explanation:
780 people receive the letter before the chain ends.
9,220 people do not send out the letter.
We have,
In the given scenario, the chain letter starts with one person sending it to five others.
Each recipient of the letter has the option to either send it to five new recipients or not send it to anyone.
Let's analyze the chain letter progression:
The first person sends the letter to 5 recipients.
Each of those 5 recipients has the choice to send the letter to 5 new recipients or not send it.
If each of the 5 recipients sends the letter to 5 new recipients, we have a total of 5 x 5 = 25 new recipients.\
If any of the 5 recipients choose not to send the letter, they are out of the chain.
Now, we have 25 recipients who received the letter and have the same choice: send it to 5 new recipients or not send it.
If each of the 25 recipients sends the letter to 5 new recipients, we have a total of 25 * 5 = 125 new recipients.
If any of the 25 recipients choose not to send the letter, they are out of the chain.
This process continues until the chain ends.
To determine how many people receive the letter and how many do not send it out, we can observe the pattern:
After the first step, there are 5 recipients.
After the second step, there are 5 + (5 * 5) = 30 recipients.
After the third step, there are 5 + (5 * 5) + (5 * 5 * 5) = 155 recipients.
After the fourth step, there are 5 + (5 * 5) + (5 * 5 * 5) + (5 * 5 * 5 * 5) = 780 recipients.
We can see that the number of recipients follows a geometric progression with a common ratio of 5.
The formula for the sum of a geometric progression is:
[tex]Sum = a (r^n - 1) / (r - 1)[/tex]
Where:
a = initial term = 5
r = common ratio = 5
n = number of steps
We are given that the chain ends after 10,000 people send out the letter. Let's calculate the number of recipients:
[tex]Sum = 5 (5^4 - 1) / (5 - 1)[/tex]
= 5 (625 - 1) / 4
= 5 624 / 4
= 780
Therefore, 780 people receive the letter before the chain ends.
To find the number of people who do not send it out, we subtract the number of recipients from the total number of people who sent out the letter:
Number of people who do not send it out = Total number of people - Number of recipients
= 10,000 - 780
= 9,220
Therefore, 9,220 people do not send out the letter.
Thus,
780 people receive the letter before the chain ends.
9,220 people do not send out the letter.

Probability of finding 4 left handers
P(x = 4) = 30C4 x (0.12)⁴ x (0.88)²⁶

A bank deposit paying simple interest at the rate of 8%/year grew to a sum of $1300 in 6 months. Find the principal. (Round your answer to the nearest cent.)
Answers
Answer:
$1,250
Step-by-step explanation:
The rate is 8%
= 8/100
= 0.08
Time is 6 months
= 1/2 year
Therefore the principal can be calculated as follows
Principal × (1+0.08(1/2) = 1300
Principal × 1+ 0.04 = 1300
Principal × 1.04= 1300
Principal= 1300/1.04
Principal = $1,250
Hence the principal is $1,250

c y=-3x+8
D y = 2x + 8
Answers
Answer:
[tex]y =-\frac{1}{2}x + 8[/tex]
Step-by-step explanation:
Given
Perpendicular to [tex]y = 2x + 1[/tex]
Pass through [tex](4,6)[/tex]
Required
Determine the line equation
First, we need to determine the slope of [tex]y = 2x + 1[/tex]
An equation is of the form:
[tex]y = mx + b[/tex]
Where
[tex]m = slope[/tex]
In this case:
[tex]m =2[/tex]
Next, we determine the slope of the second line.
Since both lines are perpendicular, the second line has a slope of:
[tex]m_1 = \frac{-1}{m}[/tex]
[tex]m_1 = \frac{-1}{2}[/tex]
[tex]m_1 = -\frac{1}{2}[/tex]
Since this line passes through (4,6); The equation is calculated as thus:
[tex]y - y_1 = m_1(x - x_1)[/tex]
Where
[tex](x_1,y_1) = (4,6)[/tex]
This gives:
[tex]y - 6=-\frac{1}{2}(x - 4)[/tex]
Open bracket
[tex]y - 6=-\frac{1}{2}x + 2[/tex]
Add 6 to both sides
[tex]y +6- 6=-\frac{1}{2}x + 2+6[/tex]
[tex]y =-\frac{1}{2}x + 8[/tex]

Write an equation of a line that is parallel to y = x - 7 and passes through the point (-6, -11).
Answers
Answer:
y = x - 5
Step-by-step explanation:
Comparing the given y = x - 7 to y = mx + b, we see that the slope is +1.
In y = x + b we replace y with -11 and x with -6 to determine the y-intercept, b:
-11 = -6 + b
Then b must be -5, and so the desired new equation is
y = x - 5

Answers
Answer:
disproportionate stratified sample
Step-by-step explanation:
Based on the given information we can say that Abel's sample is a disproportionate stratified sample. This is the case mainly because the department worker population ranges from 40 to 120 workers. This changing population makes the 10 workers that were chosen for the sample not proportionate to the entire population. Therefore, under different population sizes workers have different chances of getting selected for the study which ultimately creates different results.

Answer:

Isolate the variable by dividing each side by factors that don't contain the variable.
______________________________
1.) Subtract 2.9 from both sides:[tex]2.9-2.9=[/tex] Cancels Out. [tex]4.4-2.9=1.5[/tex].- We subtract 2.9 from both sides because we need to get rid of any extra numbers on the opposite side of the equal sign. To do so, you do the opposite of what you see: We have a positive 2.9, so we subtract.
Equation at the end of Step 1:
[tex]3f=1.5[/tex].2.) Divide both sides by 3.[tex]3f[/tex] ÷ [tex]3=f[/tex].[tex]1.5[/tex] ÷ [tex]3=0.5[/tex].- We divide 3 from both sides because the 3 is attached to the variable and we need to get the variable alone. So to do so we have to divide by 3 on each side.
3.) Turn the decimal into a fraction: [tex]0.5=\frac{1}{2}[/tex].- 0.5 is equal to [tex]\frac{1}{2}[/tex] as a fraction.

Debra paid $12.16 for a 4.07-pound bag of shrimp at one store. The following week, she paid $14.99 for a 5.11 -pound bag at another store.
Find the unit price for each bag. Then state which bag is the better buy based on the unit price.
Bound your answers to the nearest cent.
Answers
Answer:
the better buy is that from the second store as it is cheaper than that purchased from the first store
Step-by-step explanation:
Given that :
First store :
Amount paid = $12.16
Pounds of shrimps = 4.07
Unit price :
Amount paid / pounds of shrimps
$12.16 / 4.07 = $2.9877
= $2.99 = 299 cents
second store :
Amount paid = $14.99
Pounds of shrimps = 5.11
Unit price :
Amount paid / pounds of shrimps
$14.99 / 5.11 = $2.933
= 2.93 = 293 cents
Hence, the better buy is that from the second store as it is cheaper than that purchased from the first store
