sam had four test last month his scores were 81 94 83 and 91 what is the median of his scores

Answers

put them in order of least to greatest and then cross out them till you get the middle number. 81,83,91,94. answer is 91.

Final answer:

The median of Sam's test scores (81, 83, 91, 94) is 87, calculated by averaging the two middle numbers after arranging the scores in ascending order.

Explanation:

To find the median of Sam's test scores, we first list the scores in numerical order: 81, 83, 91, 94. Since there are an even number of scores, the median will be the average of the two middle numbers, which are 83 and 91. To find the median, you add those two middle scores and divide by 2: (83 + 91) / 2 = 174 / 2 = 87. Therefore, the median of Sam's scores is 87.

Calculating the median of a set of values involves organizing them in ascending order, as done with Sam's test scores. In cases where there is an even number of values, the median is determined by averaging the two middle numbers. This method ensures a representative central value for the dataset, providing insight into the typical test performance. In Sam's case, with test scores 81, 83, 91, and 94, the median is computed as 87, offering a balanced perspective on his overall performance.

Mary has 7 1/4 yard of fabric. she cuts off 3/4 foot fabric to make the edge even. Mary wants to end up with 3 pieces of fabric that are the same size. how long will each piece be?

Answers

7 1/4 - 3/4 = 6 5/4 - 3/4 = 6 2/4

6 2/4 ÷ 3 = 26/4 ÷ 3 = 26/4 x 1/3 = 2 1/6

Answer: 2 1/6 yd

Final answer:

Mary has 7 1/4 yards of fabric, and after cutting off 3/4 foot (which is 1/4 yard), she is left with 7 yards. When she divides this equally into 3 pieces, each piece will be 2 1/3 yards long.

Explanation:

Mary has 7 1/4 yards of fabric. To convert the fabric she cuts off, which is 3/4 foot, to yards, we use the fact that 1 yard = 3 feet. Thus, 3/4 foot is 1/4 yard. After cutting off 1/4 yard from her fabric, she is left with 7 yards (7 1/4 yards - 1/4 yard). Mary wants to divide this into 3 equal pieces. To find the length of each piece, we divide 7 yards by 3, which is 2 1/3 yards for each piece.

a catering company needs to know how much roast beef to slice for sandwiches for an event.They are making 30 club sandwich, which requires 1/8lb of roast beef each. They are also making 20 french dip sandwiches, which require 1/5lb each. How many pounds of roast beef should they slice in total?

Answers

1/8(30)+1/5(20)= 31/4 = 7.75
You should slice 7 and 3/4 lbs of roast beef

The would need 7 3/4 pounds (8 if you round up) of roast beef.

To find this you'd multiply 30/1 (30 as a fraction) by 1/8. To do so, you multiply straight across which gives you 30/8 or 3 3/4 when simplified. You repeat this process for the next two numbers too (20/1*1/5 = 20/5. Simplified it equals 4). Finally you add 4 and 3 3/4 together to get your answer of 7 3/4. Round up to 8 if needed.

I hope this helps!
