Answer:
A and C
Step-by-step explanation:
Equivalent expressions are expression which when simplified to lowest terms are equal.
Simplify each answer choice to find the expression which simplifies to 
.
A. Multiply the exponents 3*2 = 6. This is equal.
B. Multiply numerators and denominators. Here the numerator will be 1*1 = 1. It does not equal 2 in the numerator.
C. Here the numerator does equal 2. The denominator multiplies to 
This is equal.
D. The denominator will have three terms here when simplified. This will not be equal.
Answer:
Rs 1504
Step-by-step explanation:
Mr. Rai buys for Rs 1880.
He sells it to Mr. Sherpa at 20% discount.
1880 × 20%
= 376
1880 - 376
= 1504
Mr. Sherpa buys it for Rs 1504.

Answer:
See the explanation
Step-by-step explanation:
Ball is tossed 24 times
So the total number of outcomes (tosses) = N = 24
The ball lands in Blue section 3 times out of 24 tosses. So it becomes 3/24
The ball lands in Green section 5 times out of 24 tosses. So it becomes 5/24
The ball lands in Red section 12 times out of 24 tosses. So it becomes 12/24
The ball lands in Yellow section 4 times out of 24 tosses. So it becomes 4/24
Now we have to find how many times will the ball most likely land in the yellow section when it’s tossed 200 times. So the total number of outcomes here is N = 200. The favorable outcome here is that the ball lands in Yellow section. So we use the frequency table above for yellow section:
Yellow / Total tosses
4/24 = x/200
4*200 = 24x
800 = 24 x
24 x = 800
x = 800 / 24
x = 33.3
So ball most likely land in the yellow section 33 times when it’s tossed 200 times So it becomes 33/200 = 0.165 or 10.65% probability that ball will land in yellow section.
