Thats easy .

the 2 figures aren't the same because they're both not the same size and one
figure covers up more cubic units than the other. Also they both have different
coordinates.

Pls someone help me asap

Answer:

Area: 15.53 square inches

Perimeter: 15.71 inches

Step-by-step explanation:

Area:

So the area of the rectangle is pretty easy to find and is just the width * height. In this case it's 4 * 3 which is 12. Now the area of a circle is $\pi r^2$ . But since this is a semi circle it's half of that which is $\frac{\pi r^2}{2}$ . The diameter of the semicircle is 3 as it sits on top of the rectangle. The radius is half of the diameter so the radius is 1.5. Now plug that into the equation and you get $\frac{(3.14) (1.5)^2}{2} = 3.5325$ . Now add that to 12 and you get 15.5325. Round that number to the nearest hundredth and you get 15.53. So that's the area.

Perimeter:

Pi is the ratio of any circle's circumference to the diameter. Or in other words the circumference is equal to the diameter * 3.14. The diameter is 3 which you multiply by 3.14 to get the circumference of a circle. This will get you 9.42 but since it's a semicircle, the circumference is half of this value which is 4.71. The perimeter of the rectangle is just 2 times the width + 2 times the height. This is not completely the case in this shape since one of the sides of the rectangle is not a side of the two shapes joined together. Which is the side that is parallel to the side of length 3 inches. So the perimeter is going to be 2(4) + 3. This gives you 11 which you add to the 4.71 and get 15.71

How does a small outlier affect the data set?

leva [86]

A small outlier could affect the whole data set because it could reduce the mean, or make the average of the whole data set smaller.

An example would be the data set could be 1, 8, 9, 10

To find the mean you would add everything together then divide it by the number of numbers you just added together. The mean of this set would be 28/4 which equals 7. Now, if the outlier were -8 instead of 1, then the mean would be much different.

~Hope this helped!~

Please Help!!!

Answer:

No, the clay will not pour out easily. I know this because the angle of the truck bed is less than 50°, which is the minimum angle for easy pouring.

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that ...

Sin = Opposite/Hypotenuse

If α represents the angle of the truck bed, this means ...

sin(α) = 9/15

We can find α using the inverse sine function:

α = arcsin(9/15) ≈ 36.87°

We note this angle is less than 50° so we expect the clay will not pour out easily.
