Step-by-step explanation:
if you have a bubble letter thing its OA
Answer:
412.15 ft to the nearest hundredth
Step-by-step explanation:
You have to use the tangent function since you are given one leg of a right triangle and you are looking for the other leg
Let x = the distance from boat to lighthouse
So, tan 27 = 210/x
x tan 27 = 210
x = 210/tan 27
x = 412.14820 = 412.15 ft to the nearest hundredth
Answer:
j=5
Step-by-step explanation:
7j+20=3j+40
Step 1: Subtract 3j from both sides.
7j+20−3j=3j+40−3j
4j+20=40
Step 2: Subtract 20 from both sides.
4j+20−20=40−20
4j=20
Step 3: Divide both sides by 4.
4j/4
20/4
j=5
Answer:
j=5
Maximum and minimum value of correlation coefficient are 1 and -1 respectively.
When coefficient (r) = 1, it means that every data set values lies on a straight line or you can say that there is perfect positive linear relationship between two variables. When coefficient(r) = -1, it means that every data set values lies on a straight line but this straight line has negative slope. So they are also said to be perfect negative linearly related.
The best and most correct answer among the choices provided by the question is the third choice .
