Answer: 
Step-by-step explanation:
To find the slope of the line , we will write the equation in the form:
where:
slope
y - intercept.
To write
in this form , we will make y the subject of the formula.
Subtract 4x from both sides

Divide through by 2
Therefore :

The answer for this question is D because you have 2 full squares and then one half of square so 2 1/2.
Answer:
The given expression is a cubic polynomial with degree 3.
Step-by-step explanation:
We are given the following in the question:

Polynomial:
- A polynomial is an expression.
- It consisting of variables and coefficients.
- The variables and coefficients involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.
Since, the given expression satisfies all the properties, it is a polynomial.
Degree of polynomial:
- It is the maximum degree of the polynomial.
The degree of given polynomial is 3.
Nature of polynomial:
It is a cubic polynomial.
Male Female Total
Income over $50,000 485 385 870
Income below $50,000 65 65 130
<span>Total 550 450 1,000
Probability of being male: 550/1000 = 0.55
Probability of earning over $50,000: 870/1000 = 0.87
0.55 x 0.87 = 0.4785
Probability of being male and earning over $50,000: 485/550 = 0.8818

Answer:
B: 280
Step-by-step explanation:
The regression line predicts that when x equals 5:

In order to find the value for y, one must simply apply the following logarithmic property:
if :
then: 
Applying it to this particular problem:

Therefore, the regression line predicts y will equal 280 when x equals 5.
