Answer:

The trend line for scatterplot A will have a negative slope, and the trend line for scatterplot B will have a positive slope.

Step-by-step explanation:

The data in scatterplot A has a general decreasing trend. This is because as x increases, the values of y tend to decrease. This means the trend line will have a negative slope.

The data in scatterplot B has a general increasing trend. This is because as x increases, the values of y tend to increase. This means the trend line will have a positive slope.

The equation sin(40o) = can be used to determine the length of line segment AC. What is the length of ? Round to the nearest ten

The answer:
For more explanation please look at the image.
according to the image, the length of line segment AC can be found as
the following method shows:

<span>sin(40°)= opposite side / hypotenuse, opposite side = b, hypotenuse = AB= 20cm
</span>sin(40°)= b / 20 and this applies, b = 20 x sin(40°) = 0.64*20 = 12.85 cm
AC= 12.85 cm
