Answer:

42 1/3

Step-by-step explanation:

We subtract 26 1/6 from 68 1/2. We do this by finding the LCM of 6 and 2. That is 6. We multiply 1/2 by 3/3 to get 3/6. Now, we subtract. 68 - 26 is 42, and 3/6 - 1/6 is 2/6. Our answer is 42 2/6. That can be simplified to 42 1/3.

Julie's first three test scores in biology<br> were 65, 90 and 73. What was her<br> average score?

dedylja [7]

Answer:Julie's average score was 76

Step-by-step explanation:

The formula for Average or mean is expressed as

Average = sum of terms / total number of terms.

Julie's first three test scores in biology were 65, 90 and 73.

The sum of the scores would be

65 + 90 + 73 = 228

The number of terms is the number of subjects. Therefore, the number of terms is 3. Therefore,

Average = 228/3 = 76

Using the median concept, it is found that it suffered a 11.16% decrease.

<h3>What is the median of a data-set?</h3>

It is the 50th percentile of the data-set, which is the value that separates the lower 50% from the upper 50%.

In this problem, the ordered data-set, in thousands of £, is given by:

{19.4, 39.8, 42.3, 42.5, 45.1, 47.9, 52.4, 53.5}

It has even cardinality, hence the median is the mean of the 8/2 = 4th and 5th terms, so:

M = (42.5 + 45.1)/2 = £43800.

It decreased from £49300 last year. The percentage decrease is the change divided by initial amount and multiplied by 100%, hence:

P = (49300 - 43800)/49300 x 100% = 11.16%.

Marco borrowed $150 from his brother. He had paid back 30% so far. How much money does Marco still owe his brother?

worty [1.4K]

Answer:

He still owes $105

Step-by-step explanation:

First, we have to find how much money Marco had paid back.

We are going to find the percentage of the number:

$\frac{150 * 30}{100} = 45$

Then, doing a simple mathematical subtraction we can find how much money he still owes to his brother:

$150 - 45 = 105$
