Answer:
Large - PR - 15 and QR - 9 Missing degrees is P - 37
Small - Missing degree is 53
They are similar because they have the exca same degrees and if you divided by 3 on each side of the larger triangle you get the small triangle.
Step-by-step explanation:
Pythagorean theorem
A number cube is rolled 120 times. The number 4 comes up 47 times.
We have to determine the experimental probability of rolling a 4.
The formula to evaluate probability of an event is given by:
Probability = 
So, Probability of rolling a 4 = 
= 
Now, we have to find the theoretical probability of rolling a 4.
Total number of outcomes of number cube = {1,2,3,4,5,6}
Probability of rolling a 4 = 
So, Option B is the correct answer.
The third choice is different.
The other three you need to roll a 1 first.
A prime polynomial is one that can only be divided by itself and 1. Let's check it option.
A. x³-bx²
This polynomial can be divided by itself, 1, x and x². So it can't be prime.
B. x²-4x-12
This polynomial represents the standard form of a second order polynomial. This means that it is a parabolla. A polynomial of this form can be divided by (x-a) where "a" is the value of its roots. So it can't be prime.
C. x+8xy³
This polynomial can be divided by x, 1 and itself, therefore it can't be a prime.
D. x²-b³
This polynomial can only be divided by 1 and itself. So this is the correct answer.
Subtract 4 from 8, you get 4, then divide -2 from 4 and get 1, x=1
