Answer:
A
Step-by-step explanation:
22.5 times 3.32 results in 74.7, or A.
Answer:
844 m
Step-by-step explanation:
It is given that,
Grade 3 students used three rolls of ribbons measuring 300 metres, 286 metres and 258 metres for dance in primary Concert.
We need to find the total length of the ribbons. It means we can add all the lengths to find the total length of the ribbon. So,
Total length = 300 + 286 + 258
= 844 m
So, the total length of ribbons is 844 m.
60--------40%
15--------10%
150--------100%
1. Find the greatest common factor (GCF)
What is the largest number that divides evenly into 4x^2, -16x^4, and 10x^5?
It is 2.
What is the highest degree of x that divides evenly into 4x^2, -16x^4, and 10x^5?
It is x^2.
Multiply the results above, the GCF = 2x^2
2. Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
2x^2(4x^2/2x^2 + -16x^4/2x^2 + 10x^5/2x^2)
3. Simplify each term in parentheses
2x(2-8x^2+5x^3)
Have a nice day :D
Independent events are such events where the occurrence of any one event does not affect the occurrence of any other event.
<u>Part A:</u> rolling two number cubes at same time does not affect outcome of any one cube. It would be Independent events.
<u>Part B:</u> choosing a card, then flipping a coin according to favourable outcome can affect the result. It would be dependent events.
<u>Part C:</u> choosing a winner, keeping it, then choosing another name depends upon remaining persons. It would be dependent events.
<u>Part D:</u> drawing a marble, replacing it, then drawing another marble does not affect number of marbles in the bag. It would be Independent events.
<u>Part E:</u> flipping any coin three times does not affect past or future outcomes. It would be Independent events.
Hence, options A, D, and E are Independent events.
