For the scatter plot, if the scatter is too high and we are not able to draw the line of best fit, we say the plot doesn't show any correlation.

In A the scatter plot is rising and it is saturated on a rising line, so it is a positive correlation.

In B, we can draw a line fitting all the dots. Also it is rising. Hence it is a strong positive correlation.

In C, the scatter plot is coming down and we can still draw a line of best fit. So this is a negative correlation.

But in D, the scatter is in a huge area and we cannot draw a line around which it can be saturated.

Hence D shows no correlation.

D doesn’t show a positive or negative correlation. D is the best answer choice.

Find the area of the shaded region.
Papessa [141]

Answer:

21.46 cm²

Step-by-step explanation:

because the question want only for the SHADED REGION but NOT AREA OF THE SQUARE

(if we just multiply 10x10. you will get the area of a square which is hundered)

To find the shaded region:

1. area of a circle is πr² (we have 4 circle there)

2. Find the area of all circle

# how do we know the radius?

- half of 10 is 5

- 5 is the diameter of each circle

- the radius is half of 5 which is 2.5

- π(2.5)² = 25/4π (area of 1 circle)

3. since we have 4 circle then, 25/4π x 4 = 25π

4. the area of the square is 100cm²

5. we want the shaded region so we have to minus the area of the circle

6. 100 - 25π (use your calculator to find the answer)

answer should be 21.46 cm²

(hope this helps)

|-80|=80

|x| -≥ this symbol is named as mod

we use this to find the absolute value...

it can be explained easily as meaning like rounding off

I'm that even the number given inside in negative we should write the answer only in positive

negative number can never be the answer of absolute value

hope helpful
