Answer:
b. 0.02
Step-by-step explanation:
The smaller the p-value, the stronger the evidence that you should reject the null hypothesis. In this case, this will mean rejecting that the proportions are not significantly different.
Usually, a p-value is considered to be statistically significant when p ≤ 0.05.
From the answer options provided, alternative b. 0.02 is the only one that represents the difference in proportions to be statistically significant (there is only a 2% chance that the proportions are not significantly different).
Therefore, the answer is b. 0.02
Answer:
![2\sqrt{2}\ ft\ longer](https://tex.z-dn.net/?f=2%5Csqrt%7B2%7D%5C%20ft%5C%20longer)
Step-by-step explanation:
<u>Area Of A Cube
</u>
Suppose a cube with side length s, the area of one side is
![A_s=s^2](https://tex.z-dn.net/?f=A_s%3Ds%5E2)
Since the cube has 6 sides, the total area is
![A=6A_s=6s^2](https://tex.z-dn.net/?f=A%3D6A_s%3D6s%5E2)
But if we have the area, we can solve the above formula for s to get
![A=6s^2](https://tex.z-dn.net/?f=A%3D6s%5E2)
![\displaystyle s=\sqrt{\frac{A}{6}}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20s%3D%5Csqrt%7B%5Cfrac%7BA%7D%7B6%7D%7D)
We have two different cubes with areas 1,200 square inches and 768 square inches. Let's compute their side lengths
![\displaystyle s_1=\sqrt{\frac{1,200}{6}}=\sqrt{200}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20s_1%3D%5Csqrt%7B%5Cfrac%7B1%2C200%7D%7B6%7D%7D%3D%5Csqrt%7B200%7D)
![\displaystyle s_1=10\sqrt{2}\ ft](https://tex.z-dn.net/?f=%5Cdisplaystyle%20s_1%3D10%5Csqrt%7B2%7D%5C%20ft)
![\displaystyle s_2=\sqrt{\frac{768}{6}}=\sqrt{128}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20s_2%3D%5Csqrt%7B%5Cfrac%7B768%7D%7B6%7D%7D%3D%5Csqrt%7B128%7D)
![\displaystyle s_2=8\sqrt{2} ft](https://tex.z-dn.net/?f=%5Cdisplaystyle%20s_2%3D8%5Csqrt%7B2%7D%20ft)
The difference between them is
![10\sqrt{2}\ ft-8\sqrt{2}\ ft=2\sqrt{2}\ ft\approx 2.83\ ft](https://tex.z-dn.net/?f=10%5Csqrt%7B2%7D%5C%20ft-8%5Csqrt%7B2%7D%5C%20ft%3D2%5Csqrt%7B2%7D%5C%20ft%5Capprox%202.83%5C%20ft)
The side of the cube with area 1,200 square inches is
longer then the side of the cube with area 768 square inches
Answer:
So let's take a look into the question, "Mrs. Grudman bought a dishwasher at a special sale. The dishwasher regularly sold for
$912. No down payment was required. Mrs. Grudman has to pay $160 for the next six months. What is the average amount she pays in interest each month?"
Step-by-step explanation:
So, " Mrs. Grudman has to pay $160 for the next six months" they want us to multiply, $160
x
6
_______
960
So, 960 is your answer. Hope this helps!
Answer:
Step-by-step explanation:
You need to solve the area sector of the bigger circle. Since we now the length of sector is 270, we can set up an equation.
Length of sector DC = 2
r
270 = 2
(8+OA) *(8+OA is the raidus of the bigger circle/sector)*
270/2
= 8 + OA (division)
135/
-8 = OA
135/
-8 = OB (because OA and OB are the raidus of the same circle, so they are congruent)
I hope this helps you! Please correct me if you see a miscalculation <3<3
The better deal would be the 16 oz bag since it costs .24 cents an ounce.
You would be saving .2 cents on each ounce you buy.
