The difference between the two numbers is 48. The ratio of the two number is 7:3, what are the two numbers?
Arisa [49]

Answer:

84 and 36

Step-by-step explanation:

The ratio of two numbers is 7:3.

We don't know what the numbers are, but since their ratio is 7:3, we can let the numbers be 7x and 3x. Notice that the ratio between 7x and 3x is 7x/3x = 7/3, so we still have the same ratio, 7:3.

The difference between the numbers is 48.

7x - 3x = 48

4x = 48

x = 12

7x = 7(12) = 84

3x = 3(12) = 36

The numbers are 84 and 36.

Check:

7/3 = 2.333...

84/36 = 2.333...

84 and 36 are int he same 7:3 ratio as 7:3.

84 - 36 = 48

The difference between 84 and 36 is 48 like the problem states.

This shows our answer, 84 and 36, is correct.

Out of 200 people sampled, 52 had kids. Based on this, construct a 99% confidence interval for the true population proportion of
iragen [17]

Answer:

0.180144 < p < 0.339856

Step-by-step explanation:

According to the Question,

  • Given That, Out of 200 people sampled, 52 had kids, Thus the proportion of the mean is 52/200 = 0.26

⇒ standard error of the sample is square root(0.26 * (1-0.26) / 200) = 0.031

⇒alpha(a) = 1 - 99/100 = 0.01

⇒critical probability(p*) = 1 - a/2 = 0.995

⇒assuming a normal distribution, look for the z-score associated with 0.995 cumulative probability , z-score = 2.576

⇒margin of error(ME) = 2.576 * 0.031 = 0.079856

  • the confidence interval is 0.26 + or - 0.079856

0.180144 < p < 0.339856
