Answer:
400,000
Step-by-step explanation:
<span>Given the proportion a/b = c/d, the extremes are a and d.
The means are b and c.
To remember this, think about the terms of the proportion as being in order:
a, b, c, d. On the ends are a and d and are the extremes. Between the extremes are the means, b and c.</span>
Answer:
If one ball is selected at random, the odds for it being stripped are 7 out of 15, or 7/15.
Step-by-step explanation:
We know that there are 15 billiard balls.
We also know that balls numbered 1 through 8 are solid-colored, so we have 8 solid-colored balls.
And the other 7 balls are striped.
Now we want to find the probability for a randomly selected ball to be a striped ball.
Because all the balls have the same probability of being randomly selected, the probability of randomly selecting a striped ball is equal to the quotient between the number of striped balls (7) and the total number of balls (15).
Then we have:
P = 7/15 = 0.467
That quotient is also what is called the "odds"
So if one ball is selected at random, the odds for it being stripped are 7 out of 15, or 7/15.
Answer:
C
Step-by-step explanation:
The correct answer would be . Therefore, none of the answer choices fulfill this and A and B are not correct.
To know the answer, you need to find the common denominator. Common denominator is the multiple of a denominator which 2 or more fractions have the same denominator. The common denominator of 7/8 and 5/10 is 40 because 8*5=40 and 10*4=40.
7/8 times 5 equals 35/40 and 5/10 times 4 equals 20/40.
35/40 is greater than 20/40
So the answer is yes. 7/8 is greater than 5/10.
