Coach Manzer drove 350 miles in 5 hours and 455 miles in 6.5 hours. What is the constant rate of change?

Answers

Answer:

70

Step-by-step explanation:

It gives you two data points, (5, 350) and (6.5, 455). Constant rate of change also means slope, and the formula for slope is (y(1)-y(2))/(x(1)-x(2)). If you plug in the data points you got for this, you get (350-455)/(6.5-5), which is equal to 105/1.5. Drop that in a calculator and you get 70.

Colin invests £4000 into his bank account.
He receives 5% per year simple interest.
How much will Colin have after 3 years?

Answers

Answer:

4,600

Step-by-step explanation:

A = P(1 + rt)

P = 4000

r = 0.05 (rate in percent form)

t = 3 years

A = 4000(1 + (0.05)(3))

A = 4000(1+0.15)

A = 4000(1.15)

A = 4,600

Answers

Answer:

Cluster

Step-by-step explanation:

The Cluster sampling technique involves choosing a population to be studied and dividing it into clusters that truly represent the population, through random sampling. In the question above, all the customers in the restaurant represent the population to be studied. Since all the customers can not be interviewed at that time, clusters, in the form of tables are formed through random sampling.

It is necessary for the researcher to ensure that the customers in all the table clusters truly represent the population.

Write a function inches_to_ft that takes a number of inches x and returns the number of feet. One foot equals 12 inches.

Answers

Answer:

def inch_to_feet (x):

return 1/x

Step-by-step explanation:

Implementating the program Using python 3 :

def - - - > function declaration keyword

inch_to_feet - - > function name

x - - > argument which the function takes

The value returned is a conversion of x which is in inches to feets

1/12 feet = 1 inch

To see the value returned ;

We can run the code :

def inch_to_feet(x):

return (1/12)*x

b = inch_to_feet(12)

print(b)

The code above will print 1.

Plot the intercepts to graph the equation. x+y=3

Use the graphing tool to graph the equation. Use the intercepts when drawing the line. If only one intercept​ exists, use it and another point to draw the line.

Answers

Answer:  You will have points plotted at +3 on the y axis, and +3 on the x axis.

The attachment shows what your graph should look like.

Step-by-step explanation:

The intercept is where the graphed line crosses an axis.

To find the y-intercept, substitute 0 for x and solve for y:

0 + y = 3.  Subtracting 0, you have y = 3

So you can plot a point at +3 on the y axis.

To find the x- intercept, substitute 0 for y, and solve for x

x + 0 = 3  Again, subtracting 0, x = 3

So plot a point on the x-axis at +3

Use the line tool to connect the two points.

(Simplify your answer. Type your answer in slope-intercept form. Use integers or fractions for any numbers in the expression.)

Answers

Answer:

[tex]y = -6x + 39[/tex]

Step-by-step explanation:

The equation of a line has the following format:

[tex]y = mx + b[/tex]

In which m is the slope and b is the y-intercept(value of x when y = 0).

We have that the slope is m = -6:

So [tex]y = -6x + b[/tex]

Contains point (5,9):

This means that when [tex]x = 5, y = 9[/tex]. We replace this into the equation to find b. So

[tex]y = -6x + b[/tex]

[tex]9 = -6(5) + b[/tex]

[tex]b = 39[/tex]

So

[tex]y = -6x + 39[/tex]
