Answera and Step-by-step explanation: Correlation Coefficient is the measure of how strong two variables are. There are numerous types of correlation coefficients and the product moment correlation coefficient, also known as <em>Pearson's correlation</em> or <em>Pearson's R</em> is most commonly used in linear regression. The formula to calculate it is:
r = n(∑xy) - (∑x)(∑y) / √[∑x² - (∑x)²].[n∑y² - (∑y)²]
To find the value of R:
1) Separate the values of X and Y and out them in 2 columns.
2) Add 3 more columns: for xy, x² and y²;
3) Find the values of each column;
4) Add each column;
5) Put the sum of each column in its place on the formula above;
6) Find the correlation.
i) For this question, r = 0.9645. As it's <u>positive</u>, means that the two variables are directly linked, i.e., an increase in one variable will produce an increase in the other variable in the same proportion.
ii) The Senator should distribute Norvasc to the old adults groups, because, as the <u>population grows</u>, the death associated with high blood pressure will <u>also grow</u>, as explained by the correlation coefficient.

Molly’s monthly payment by using the Bankrate calculator is $286 per month.
It is given that
The downpayment Molly has = $2500.
Interest rate APR = 1.9%
Cash allowance by dealer = $500
Selling price = $25,495
Loan tenure N= 7 years
Amount of loan needed = 25495-2500-500 = $22495
<h3>What is Equated monthly payment(EMI)?</h3>
An equated monthly installment (EMI) is a set monthly payment provided by a borrower to a creditor on a set day, each month.
The EMI or monthly payment will be calculated by the following formula,
Put APR =0.019(decimal value of APR)
N = 7
EMI = $286 per month.
Therefore, Molly’s monthly payment by using the Bankrate calculator is $286 per month.

AC # A'B'
Step-by-step explanation:
While solving the above problem one must keep in mind that
- Reflection along Y-axis would just make the rectangle upside down at the same distance from X-axis in the down direction.
Thus, from the figure it becomes clear that
- AB ∦ B’D’
- CD║A’B’
- BD ∦ C’D’
Only statement that comes out true is the third statement which states that AC is not parallel to A’B’
Since the diagonal of a rectangle can not be parallel to one of its side (though the side in question is side of the same rectangle reflected in y axis)
