The answers are:
a^2-36
w^2-121
To find the area of the shape, you can split the shape into 2 shapes, a rectangle and a triangle. The area of a rectangle is A=l x w and the area of a triangle is A=1/2 bh. The are of the rectangle is 200 since 20 times 10 is 200. The area of the triangle is 20 times 4 divided by 2. The area of the triangle is 40. Add both areas to get the total are of 240. The area of the shape is 240.
Answer:
12
Step-by-step explanation:
1/2x=3/4x−3⇒2x=3x−12⇒x=12
Complete options are;
A) Paired t-test for means
B) Paired Z-test for means
C) Z-test for proportion
D) t-test for means
E) Z-test for means
F) t-test for proportion
Answer:
B) Paired Z-test for means
Step-by-step explanation:
We are told that the distances travelled are normally distributed.
We are also trying to find out if the average distance travelled by the Titleist Pro V1 golf balls is farther than that of the Callaway Chrome Soft golf balls.
Also, the standard deviation of both cases are known.
Thus, this is where Paired Z-test for means is used.
