Answer:
the ratio of the surface area of Pyramid A to Pyramid B is:
Step-by-step explanation:
Given the information:
- Pyramid A : 648
- Pyramid B : 1,029
- Pyramid A and Pyramid B are similar
As we know that:
If two solids are similar, then the ratio of their volumes is equal to the cube
of the ratio of their corresponding linear measures.
<=>
=
=
= ![\frac{216}{343}](https://tex.z-dn.net/?f=%5Cfrac%7B216%7D%7B343%7D)
<=> ![\frac{a}{b} =](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7Bb%7D%20%3D)
![\frac{6}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B7%7D)
Howver, If two solids are similar, then the
n ratio of their surface areas is equal to the square of the ratio of their corresponding linear measures
<=>
=
So the ratio of the surface area of Pyramid A to Pyramid B is:
B, 1 2/5
Step-by-step explanation:
By subtracting that amount from 3, using a common facotor. You would get B.
Answer: n= 15
p= 0.30
Step-by-step explanation:
Binomial distribution :
Let x be a binomial variable.
The probability of getting success in x trials is given by :-
, where n is the total number of trials and p is the probability of getting success in each trail.
Given : The proportion of parolees from prison return to prison within 3 years= 0.30
We assume that whether or not one prisoner returns to prison is independent of whether any of the others return to prison.
⇒ p =0.30
Let the random variable X be the number of parolees out of 15 that return to prison within 3 years.
⇒ n= 15
Answer:
This formula is in slope-intercept form. 3 is the slope (positive slope) and <u>-2 is the y-intercept.</u>
