Answer:
None. Wanda's work is correct.
Step-by-step explanation:
The first is correct.
The answers are 3/8 and 1/6.
There are 8 possible outcomes in the sample space for flipping 3 coins. Of those, 3 include two heads and 1 tail. This makes the probability 3/8.
Choosing a quarter for the first coin is 3/10, since there are 3 quarters out of 10 coins. After this, choosing a dime is given by 5/9, since there are 5 dimes out of 9 coins left:
3/10(5/9) = 15/90 = 1/6
Answer:
83
Step-by-step explanation:
its a guess bc its a right triangle and right triangle is 90 degrees minus 7 is 83
Answer:
Three equivalents ratios for 6/9 could be 2/3, 12/18 and 18/27
Step-by-step explanation:
An equivalent ratio refers to the same number but written differently. For example, for the ratio 6/9, we could obtain the following equivalent ratios.
First equivalent ratio
You can divide the numerator and denominator by 3. You get 2/3

Second equivalent ratio
You can multiply the numerator and denominator by 2. You get 12/18

Third equivalent ratio
You can multiply the numerator and denominator by 3. You get 18/27

Thus, three equivalents ratios for 6/9 could be 2/3, 12/18 and 18/27
