Use rounding or compatible numbers to estimate the sum 302+412

Answers

Answer 1

Answer: i think it would be 710 because you can round the 302 to 300 and then 412 to 410 and then you add the but it asks to estimate so it would probably be 700

Answer 2

Answer: well i just looking at the first numbers of each one and added those up that became 700 and since the numbers behind them arent so big it rounds out to 700:))

Imagine each letter of the word “Mathematical” is written on individual pieces of paper and placed in a bag. Should you pick a random letter from that bag, what is the probability that you pick a vowel?

Answers

Answer:

The probability to pick a vowel is $(5)/(12) }$

Step-by-step explanation:

Probability = Required outcome / All possible outcome

From the question;

the word “Mathematical” is written on individual pieces of paper

We have to count the total numbers of letter present in the word

When we count properly, we have 12 total numbers of letters

The we proceed to count the numbers of vowel

Here are the vowel in the word “Mathematical” :

a, e, a, i, a

The vowels are 5 letters

Probability = Required outcome / All possible outcome

Required outcome = 5

All possible outcome = 12

Probability = $(5)/(12) }$

The probability that you pick a vowel is $(5)/(12) }$

In the word "Mathematical"

Vowels are "a", "e", "a", "i", "a" from left to right

Consonants are "m", "t", "h", "m", "t", "c", "l"

5 vowels and 7 consonants of total 12 letters

So the probability of picking a vowel is

$(5)/(12)$
