Jordan will hike the trail shown at a rate of 2 mi/h. Write a linear equation to represent the distance Jordan still has to
walk after x hours. What does the y-intercept of the equation represent?
Answers
Answer:
If y represents the distance Jordan still has to walk after x hours, then the equation [tex] y = -2x + 13 [/tex] describes the given equation.
The y-intercept of the equation represents total distance of the trail
Step-by-step explanation:
A linear equation can be written to represent the situation above using the slope-intercept equation form, which is given as [tex] y = mx + b [/tex]
Where,
m = slope or rate of change = -2 mi/h (the slope is negative, because distance remaining decreases as hours increases)
b = y-intercept = 13 miles (this is the total distance of the trail. x (hours) is zero at this point)
The equation of the given situation, in slope-intercept form would be:
[tex] y = -2x + 13 [/tex]
A linear equation can be use to describe Jordan's distance because the
rate of change of the distance with time is constant.
First part: The linear equation is; y = 13 - 2·xSecond part: The y-intercept represents the total distance of the trail.Reasons:
From the map in the question, we have;
The distance of the trail Jordan has to hike = 13 miles
The rate at which Jordan will work = 2 mi/hr.
Part One:
Required:
The linear equation that represents the distance Jordan still has to walk
after x hours.
Solution:
Let y represent the distance Jordan still has to walk after x hours
The distance walked per hour = 2 miles
The distance walked after x hours = x × 2 miles = 2·x miles
Total distance = 13 miles
Distance remaining = Total distance - Distance walked
Distance remaining, y = 13 - 2·x
The linear equation that gives the distance Jordan still have to walk after x hours, is therefore;
y = 13 - 2·x
Second part:
The y-intercept is the y-value when x = 0
Therefore;
The y-intercept is; y = 13 - 2 × 0 = 13
Therefore;
The y-intercept represents the distance Jordan has to walk at the start
when the time, x, is 0, which is 13 miles or the the entire distance Jordan
has to walk.

The amount of milk that the bakery used this month was a 75% decrease relative to last month. What is the new amount of milk using percent?
Answers
Answer:
25%
Step-by-step explanation:
the answers
The new amount of milk using percent is 25.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then the percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
We are given that the amount of milk that the bakery used this month was a 75% decrease relative to last month.
Therefore, for last month, we have a rectangle with four equal areas 75% decrease,
we have to remove 3 areas to make the remaining = 25%
So, the difference will give a 75% decrease

Step-by-step explanation:
49y^2 - 25x^2 - 196y - 200x = 1429
49y^2-196y+196 - 25x^2-200x-400 = 1429+196-400
49(y-2)^2 - 25(x+4)^2 = 1225

Every quarter, the Food and Drug Administration (FDA) produces a report called the Total Diet Study. The FDA's report covers a variety of food items, each of which is analyzed for potentially harmful chemical compounds. A Total Diet Study reported that no pesticides at all were found in % of the domestically produced food samples. Consider a sample of food items analyzed for the presence of pesticides. Complete parts a and b. a. Compute and for the random variable x, the number of food items found that showed no trace of pesticide. nothing (Type an integer or a decimal.)
Answers
Answer:
a) Mean = 600
Standard deviation = 12.24
B)No it is not likely because our probability of no pesticide is 75% which means that more than half of food items are without any pesticide
Step-by-step explanation:
Total number of food items = 800
We are given that no pesticides were found at all in 75% of domestically produced food samples.
So, Probability of success = p = 0.75
Probability of failure = q = 1-p = 1-0.75=0.25
Now we are supposed to find [tex]\mu[/tex] and [tex]\sigma[/tex] for random variable x
a) Mean = E(x)= [tex]n \times p = 800 \times 0.75=600[/tex]
Standard deviation =[tex]\sqrt{npq}=\sqrt{800 \times 0.75 \times 0.25}=12.24[/tex]
b)Is it likely that you would observe fewer than half of the food items without any traces of pesticides ? Why or why not ?
No it is not likely because our probability of no pesticide is 75% which means that more than half of food items are without any pesticide

determine the slope of the line given this two points (-2,4) and (1,6) with solution
Answers
Answer:
Slope = y2 - y1/x2 - x1
Slope = 6-4 / 1--2
Slope = 2/3
Step-by-step explanation:
hope that will help you
The slope of the line will be 2/3.
The formula for the slope will be:
= (y2 - y1) / (x2 - x1)
where,
y2 = 6
y1 = 4
x2 = 1
x1 = -2
We will slot the values into the equation which will be:
= (y2 - y1) / (x2 - x1)
= (6-4) / (1- -2)
= 2/(1+2)
= 2/3
Therefore, the slope is 2/3.

Step-by-step explanation:
The Volume of a Sphere
The volume of a sphere of radius r is given by:
[tex]\displaystyle V=\frac{4}{3}\cdot \pi\cdot r^3[/tex]
The radius of the sphere is r=7 cm, thus:
[tex]\displaystyle V=\frac{4}{3}\cdot 3.14\cdot 7^3[/tex]
[tex]V=1436.03 \ cm^3[/tex]
Note: We have used an approximated value for pi=3.14.
The volume of the sphere rounded to the nearest hundredth is
[tex]\boxed{V=1436.03 \ cm^3}[/tex]

I can't solve this problem: 47 x 98= ( ? x 47)-(2 x 47)
Answers
Answer:
The answer to your question is:
2 and -49
Step-by-step explanation:
2 x -49 = -98
2 + (-49) = -47
x2 - 47x - 98 = 0
The solution to factor the quadratic equation above is:
(X + 2 ) (X - 49)
Since 2 and -49 multiply to -98 and add up -47, you know that the following is true:
x2 - 47x - 98 = (X + 2 ) (X - 49)
