Answer:
(5,1)
Step-by-step explanation:
A vertex is where two or more curves, lines, or edges meet
Answer:
y=8
Step-by-step explanation:
Answer:
for perimeter you add all sides. so Lenth x2 + width x2 is 24+30 which would equal 54
for area it's Lenth times width so 12 times 15 equals 156
Answer:
The distance between C and D is 650 miles
Step-by-step explanation:
1.5 over 250
and
3.9 over x
so 3.9 *250 = 975
975/1.5 = 650
making x (the distance between C and D) = 650 miles
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.
