Answer:

Scatter plot attached below.

Step-by-step explanation:

The correlation coefficient is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent).It ranges from -1 to +1.

If there is any alteration in the value of one variable, the value of the other variable is altered in a fixed proportion. The correlation amid them is known as perfect correlation.

In statistics, a perfect positive correlation is represented by +1 and -1 indicates a perfect negative correlation.

Negative correlation is a relationship amid two variables in which one variable rises as the other falls, and vice versa.

The scatter plot for the correlation between x and y closest to −1 is attached below.

If i put a penny in a jar every day for a year how much money will i have

katovenus [111]

Hi there!

A year is 365 days, correct?
If we save our pennies up from January 1st to December 31st, you'd have 3 dollars (since 100 pennies is 1 dollar) and 65 pennies left over. If it was a leap year, however, you'd have 3 dollars and 66 cents. :)

Hope this helps! :D

Q# ..7 match the equation with its graph -4x - 2y =8

prisoha [69]

If you divide by 8, you can put the equation into intercept form. That form is ...

... x/a + y/b = 1

where <em>a</em> and <em>b</em> are the x- and y-intercepts, respectively.

Here, your equation would be

... x/(-2) + y/(-4) = 0

The graph with those intercepts is not shown with your problem statement here. See the attachment for the graph.

What is the degree of the following polynomial f(x)=(x+4)^3(x+1)(x-5)^3

Lelechka [254]

Answer:

x^7

Step-by-step explanation:

look for the highest degree of any term and you will end up multiplying

x^3( from first paranthesis) *x( from second parenthesis) *x^3 ( from third paranthesis) so the highest degree will be x^ 3+1+3 = x^7

The total charge in dollars for a car rental can be determined by using the function c = 0.4x + 35, where c represents the total

andrew11 [14]

Answer:

There is an initial charge of $35.00 for every mile traveled.

Step-by-step explanation:

From the question, the cost function s given as follows:

c = 0.4x + 35 .................... (1)

Where;

Total cost = c

Variable cost per mile = $0.40

Number of miles traveled = x

Total variable cost = 0.4x = 0.40 * x

Fixed cost = Initial cost = $35

From the above, the fixed cost or initial cost implies that no matter the number of miles a passenger takes, he is going to pay $35 in addition to the variable cost to pay.

From the question, for driving a distance of 100 miles we have:

Number of miles traveled = x = 100

Total variable cost = 0.40 * 100 = 40

Substituting the relevant value into equation (1), we have:

c = 40 + 35

c = 75

Since the total cost obtained above is $75.00, it therefore implies that the correct statement that justifies that the total cost for renting this car and driving a distance of 100 miles is $75.00 is "There is an initial charge of $35.00 for every mile traveled".
