Answer:
A. The data show a negative linear relationship.
Step-by-step explanation:
According to the attached image as we can see that the temperature is in Y axis and volume of ice cubes is in X axis
So the following statements considered to be true
a. The volume represents the explanatory variable
b. Temperature would be strongly correlated to the ice cubes volume
c. As the correlation coefficient is near to -1
But it does not show the negative linear relationship
Therefore the correct option is a.
Tanα=h/x
h=xtanα, we are told that x=6.5ft and α=74° so
h=6.5tan74 ft
h≈22.67 ft (to nearest hundredth of a foot)
Answer:
The correct option is 1. The area of cross section area is 48 mm².
Step-by-step explanation:
From the find it is noticed that the cross section is a rectangle with length 4 mm and width is 12 mm.
The area of a rectangle is the product of its dimensions.
Where, l is length of the rectangle and w is width of the rectangle.
The area of cross section is
Therefore the area of cross section area is 48 mm². Option 1 is correct.
There would be 2034 students competing in 2012.
We can write a simple equation to find this answer. Let X, be the number of students starting in 2012. Then, we multiply by 0.9 and 1.1 to get to 2014. To work backwards, just divide by 1.1, then by 0.9.
2014 / 1.1 / 0.9 = 2034
