Answer:
Step-by-step explanation:
2 right triangles and three rectangles
Answer:
The fourth one J is the answer
Step-by-step explanation:
we only need to find one point(0,-2)
the following selections only the fourth one
when x=0 ,y=-2
Answer:
It would be significant
Step-by-step explanation:
Population proportion of consumers who recognize the company name = 68% = 0.68
If 634 consumers out of the 800 randomly selected consumers recognize the company name, sample proportion = 634/800 = 0.7925.
It is significant to get 634 because the sample proportion of consumers who recognize the company name is greater than the population proportion.
Answer:
The length would be 30 and the width would be 20
Step-by-step explanation:
For the purpose of this, we'll set the width as x. We can then define the length as x + 10 since we know it is 10 ft longer than the width. Now we can use those along with the perimeter formula to solve for the width.
P = 2l + 2w
100 = 2(x + 10) + 2(x)
100 = 2x + 20 + 2x
100 = 4x + 20
80 = 4x
20 = x
Now since we know that the width is 20ft, we can add 10ft to it to get the length, which would be 30ft.
centre: (0,0)
Radius: square root of 30
