The ratio between the surfaces areas of the two prisms is equal to 6.25.
<h3>
How to get the ratio of the surface areas?</h3>
The ratio between the volumes of the prisms is:
This number is equal to the cube of the scale of dilation applied to the dimensions of the smaller prism, so the scale factor is:
![\sqrt[3]{15.625} = 2.5](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B15.625%7D%20%3D%202.5)
And the ratio between the areas should be the square of the scale factor, then we will have that the ratio between the surface areas of the two prisms is:

Answer:
I is good at geometry but i aint got insta.
Step-by-step explanation:
Answer: Mean of the sample proportion = 74.4
Standard deviation of the samnple proportion is 5.32.
Step-by-step explanation:
Given : A random sample of 120 is taken from a population of 10000.
Let n = 120
Also, from previous survey, it is believed that 62% of the population has an Instagram account.
i.e, population proportion : p = 0.62
Now , the mean of the sample proportin would be :
i.e. Mean of the sample proportion = 74.4
The standard deviation of the samnple proportion would be :
Thus , the standard deviation of the samnple proportion is 5.32.
Answer:
-1
Step-by-step explanation:
The y-intercept can be found when x=0, so find f(x) when x=0. So the first step is to evaluate (2/3)^0, which is 1. According to the equation this is multiplied by -1, so the y-intercept is -1. You can also use a graphing calculator (or Desmos) so you can see a physical representation of it. Hope this helps! :)
We start with 90,500
to get 10% we multiply it by .10
90,500 * .10 =
<u>9050</u>
