0.50=1/2 And 7 1/2=15/2
Multiply numerators and denominators. 15*1=15
2*2=4
You get 15/4. This is equivalent to 3 3/4 and is also equivalent to 3.75

Hope this helps!

In a race, the-second place finisher crossed the finish line 1 1/3 minutes after the winner. The third-place finisher was 1 3/4

KiRa [710]

Answer:

First Winner take 31.95 minute time to complete race.

Step-by-step explanation:

Since the third winner take $34\frac{2}{3}$ minutes to complete the race.

Second winner take $1\frac{3}{4}$ minutes less than Third Winner.

Thus Second winner take $34\frac{2}{3}-1\frac{3}{4}\\ \frac{104}{3}-\frac{7}{4}\\ \frac{395}{12} =32.92 \ minutes$

Also, First winner take $1\frac{1}{3}$ minutes less time.

Thus first winner take time = $\frac{395}{12}-1\frac{1}{13}\\ \frac{395}{12}-\frac{14}{13}$ =31.95 minutes

Mr. Santiago can buy light fixtures in packages of 12 and light bulbs in packages of 9. He bought the fewest number of light fix

miskamm [114]

List the multiples of both 12 and 9:

12, 24, 36, 48, 60

9, 18, 27, 36, 45

The lowest common multiple is 36.

This will make the fixtures and bulbs equal.

This means they bought 3 packages of light figures 3 x 12 = 36)

And bought 4 packages of bulbs ( 4 x 9 = 36)

The sum of two consecutive even integers is 186. What are the two numbers?

ozzi

Answer: 92 and 94

Step-by-step explanation:

x = first number

x + 2 = second number

x + x + 2 = 186

simplify

2x + 2 = 186

subtract 2 from both sides

2x = 184

divide both sides by 2

x = 92

92 + 2 = 94

The numbers are 92 and 94.

If each customer takes 3 minutes to check out, what is the probability that it will take more than 9 minutes for all the custome

AnnyKZ [126]

Using a discrete probability distribution, it is found that there is a 0.15 = 15% probability that it will take more than 9 minutes for all the customers currently in line to check out.

<h3>What is the discrete probability distribution?</h3>

Researching the problem on the internet, it is found that the distribution for the number of customers in line at the store is given by:

P(X = 0) = 0.2;

P(X = 1) = 0.15;

P(X = 2) = 0.30;

P(X = 3) = 0.20;

P(X = 4) = 0.10;

P(X = 5) = 0.05;

Hence, since each customer takes 3 minutes to check out, the probability that it will take more than 9 minutes for all the customers currently in line to check out is the probability that there are more than 3 customers, hence:

P(X > 3) = P(X = 4) + P(X = 5) = 0.10 + 0.05 = 0.15.

0.15 = 15% probability that it will take more than 9 minutes for all the customers currently in line to check out.
