Answer:
Null hypothesis: proportion of red Phillies cars is 0.12.
Alternate hypothesis: proportion of red Phillies cars is not 0.12.
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
multiply 40 x 20 which =80
then put a point after the 8 then add a 0.
Your final answer should be 40% of $20 is $8.00
X/-10 = 7
Step 1: Multiply by -10
(x/-10)*-10 = 7*-10
x = -70
By graph of object A the rate of change is estimated at 17/6.
Object B's rate of change is 10/3=20/6.
Comparing object A to object B:
17/6 <20/6
Object B is faster by:
17/6x=20/6
(6/17)(17/6)x=(20/6)(6/17)
x=20/17≈1.18
B)
Object B by a factor of 1.19
Since I made an estimation from graph of object A , my solution is off by. 01 but it is the closest I can get. The solution B is correct.
No, it does not.
In general, surface area is the sum of the areas of each face of a prism. In a rectangular prism, we have length, width, and height.
The area of the bottom of the prism and the top of the prism is the same, and can be represented as l*w. This means that together, it is 2lw.
The area of the left and right faces of the prism is the same, and can be represented as l*h. This means that together, it is 2lh.
The area of the front and back faces of the prism is the same, and can be represented as w*h. This means that together, it is 2wh.
This gives us the equation
SA = 2lw+2lh+2wh
If we double the length and width, making them each 2l, we then have:
SA = 2(2l*2w) + 2(2l*h) + 2(2w*h)
= 2(4lw) + 4lh + 4wh
= 8lw + 4lh + 4wh
If the surface area had been doubled, we would expect
4lw + 4lh + 4wh
No, it is not doubled.
