Find an equation for each line:

Line ℓ: y =
Line m: y =
Line n: y =
Line p: x =

If you helped, thank you so much, you are an amazing person <3

Answers

Line P: x = -4

Line n: y = x -1

Line m: y= -2x + 4

Line l: x = 4

No problem =)

The equation of the lines are,
Line ℓ: y = 4

Line m: y = -2x + 4

Line n: y = x - 1

Line p: x = -4

What is a line?

A line is a straight curve connecting two points or more showing the shortest distance between the initial and final points.

Here,
From the map,
Locate at least 1 point in every line to define the equation of line,
Consider line l,
Now, on the y-axis line l passes through (0, 4),
Standard equation of the line,
y = mx + c,
Since the slope of the line l is zero and the y-intercept is 4, so the equation is,
y = 0(x)  + 4
y = 4

Similarly, the equation of the other line is givens,
Line m
y =  -2 + 4  (slope is -2 and y-intercept is +4)

Line n,
y = x - 1    (slope is 1 and y-intercept is -1)

Line p
x = -4   (slope is 1/0 and y-intercept is 0)

Thus, the equation of the line is shown above.

A skin care company had 1,500 people try a new acne cream. Nine people had a mild reaction the formula is then improved and those 1,500 people try the new cream only 4

Answers

Answer:

The percent decrease in number of allergic reactions is 55%

Step-by-step explanation:

Only 4 of them had a mild allergic reaction. What is the percent decrease in number of allergic reactions?

Percent of allergic people= Allergic people/ Total people * 100

                                         = 9/1500* 100

                                         = 0.6 %

IT means that out of 1000 people only 6 persons are allergic to the cream.

New Percent of allergic people= Allergic people/ Total people * 100

                                         = 4/1500* 100

                                         = 0.267 %

It means that out of 1000 people only 2.67 persons are allergic to the new improved cream.

Difference between Percentage = Old Percentage- New Percentage

                                                      = 0.6 %- 0.267%

                                                       =0.333%

Decrease= 0.333% = 0.333/100

In every thousand people 3.33 people are free of allergic reactions from those 6 allergic people.

Percentage Decrease= Decrease/ Total * 100

                        = 0.333/ 0.6 *100

                           = 0.55*100

                            = 55 %

The percent decrease in number of allergic reactions is 55%

A family has 4 horses bred from the same set of parents. All of their horses are mares (females). They are planning on having one more horse to complete their herd. A neighbor comments that they are much more likely to end up with a male horse the next time around. Is the neighbor’s reasoning correct?
a. Yes, they are more likely to end up with a male horse in order for the probabilities of male and female to get back to 0.5
b. No, the probability of the new horse being male or female remains 0.5, regardless of what its older siblings are.
c. Yes, after having so many female horses in a row, the breeding pair is due to have a male.
d. No, these horses must be genetically prone to having female offspring
