# X | Y 0 | 15 5 | 10 10 | 5 15 | 0 What is the correlation coefficient for the data shown in the table? A: 1 B: -1 C: 5 D: 10

B: -1

Step-by-step explanation:

Here as the value of X is increasing, the value of Y is get decreased. Thus Negative Correlation is exist here.

Also, if we notice here the values of both the observation are just reciprocal.

Thus, the Value of Correlation Coefficient is exact -1.

The Correlation Coefficient is the strength and direction of relationship between two variables. And its value lie between -1 to +1.

The graph of a system of equations with the same slope and the same y-intercepts will have no solutions. Always
Sometimes
Never

If 2 equations have the same y-intercept, they are overlapping, which means they have infinite solutions. So there is no way that 2 equations with the same y-intercept will have no solution. Thus your answer is: C)Never.

-3 + 9 ( 102 - 4 ) (simplify)

Step-by-step explanation:

The order of operations calls for Parenthesis, Multiply, Divide, Add, Subtract. From left to right.

So we do the parenthesis first (102 - 4)

-3 + 9 (98)

Next we multiply 9 and 98

-3 + 882

Lastly we add -3 and 882

Gina's mother bought 200 lollipops and 150 pencils for goody bags for Gina's birthday. What is the largest number of goody bags that Gina can make to get the same number of lollipops and the same number of pencils in each goody bag? (All lollipops and pencils should be used).

In total maximum  50 goodies bags can be made, such that:

Step-by-step explanation:

Here, the total number of lollipops  = 200

The total number of pencils  = 150

Now, let us find the Highest Common Factor (HCF) of 200 and 150,

Here, 200  = 2 x 2  x 2 x 5 x 5

and, 150  = 2 x 3 x 5 x 5

SO, HCF of  200 and 150  = 2 x 5 x 5 = 50

Hence, in total 50 goodies bags can be made, such that:

1 bag  = 200 ÷ 50 = 4 lollipops

and  1  bag  = 150 ÷  50 = 3 pencils

⇒  1 bag  = 4 lollipop + 3 pencil =7 items.
