The slope I got was 6/9 which can be reduced down to 2/3
Answer:
19 units
Step-by-step explanation:
Perimeter of the rectangle = 124 units
width = x units
length = 5 + 2x units
The perimeter of a rectangle is given by;
P = 2(l + b)
Substituting values;
124 = 2[(5 + 2x) + x]
124 = 2[5 + 3x]
124 = 10 + 6x
124 - 10 = 6x
114 =6x
x= 114/6
x = 19
width = 19 units
Answer:A

Answer:
lol thats funny
Step-by-step explanation:
Using a calculator, it is found that the correlation coefficient for this data is given by:
B. -0.901.
<h3>What is a correlation coefficient?</h3>
- It is an index that measures correlation between two variables, assuming values between -1 and 1.
- If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
- If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.
To find the coefficient, which has symbol r², we input in a calculator the values of x and the values of y, hence:
r² = -0.901.
Which means that option B is correct.
