4x = 6x -10
2x = 10
x = 5
answer
x = 5
Mean = 133.9
then calculate the z value
with z value you will find out the p value on a table.
if the p value is below .05 reject the null hypotheses
10.2 feet
Divide 3.24 by 3.14 and find the square root of the result.
Answer:
235 cm²
Step-by-step explanation:
Find area of the large rectangle on the bottom. To do that, find its length and width, then multiply them together.
Length of big rectangle=20 cm
Width of big rectangle=9 cm
20x9=180 cm²
Next, find the area of the small rectangle on the top. To do that, find its length and width, then multiply them together.
Length of small rectangle=11 cm
Width of small rectangle=5 cm
I found the width by subtracting 9 from 14, since the 9 cm is part of the large rectangle.
11x5=55 cm²
Add the areas of the two rectangles.
55+180=235 cm²
You would need to do 10.5/3.5. This equals 3ft
