Answer:
25
Step-by-step explanation:
If two ratios have the same value when simplified, then they are called Equivalent Ratios.
Equivalent ratios can be obtained by multiplying or dividing both sides by the same non-zero number.
As we want 3 equivalent ration in higher terms we will multiply it
4 : 7
by multiply with 2
4* 2 : 7* 2
8 : 14
by multiply with 3
4* 3 : 7* 3
2 : 21
by multiply with 4
4* 4 : 7* 4
16 : 28
you can multiply with any nonzero number
Hope this helped!
Have a great day!
Answer:
The number of candies Hayley has is 16 .
Step-by-step explanation:
The number of candies Hayley has = x
So, Number of candies Hayden has = (x + 3)
Then the Number of candies i have = 2(x + 3)
Also,according to the question:
2(x + 3) = 38
or, 2x + 6 = 38 ⇒ 2x = 32
or, x = 32/2 = 16
⇒ x = 16
So, the number of candies Hayley has is x = 16 .
The reason why the sum of your probabilities equals 0.5 is because you're only considering half of the problem--i.e. the probabilities for only one gender. For example, the probability that there are only three children and all are boys is 1/8. But, remember, it could be the case that there are three children and all are girls. Thus, the probability that there are three children is 1/4--not 1/8. Thus, multiply your result for P(X=4) and P(X=5) by 2 and you should end up with the right answer...
