Answer:

First you have to find the area of the triangles, and you do so by using the formula A = (B·H)/2, where the a represents area, b represents base, and h represents height. Assuming all of the triangles are the same, you multiply 7 by 11 and then divide by 2 which equals 38.5 and then multiply that by 4 which equals 154 and then you have the area of all four triangles combined. Then to find the area of the cube you simply square 7, which results in 49, and then add that to the area of the triangles, which leaves you at 203. <u>203 square inches is your answer. </u>

3/4 of 24 is 3 groups of 6, which is 18. So Han ate 18 less than Tyler, or Han at 6. So you take the 24(x) and you subtract 24 o

aksik [14]

Answer:

Step-by-step explanation:

Let the total amount ate by Tyler and Han be 24

Let the amount Tyler ate be x

Amount Han ate be y

If Tyler ate 3/4 of the total, then Amount ate by Tyler is expressed as;

x = 3/4of 24

x = 3/4×24

x = 3×6

x = 3(6)

x = 18

Hence the amount Tyler ate is 18

If Han ate 18 less than Tyler, the amount ate by Han will be;

Han y = 24-(3/4(24)

y = 24-{3(6)}

y = 24-18

y = 6

Hence the total Han ate is 6

If a data set contains 10,000 values arranged in increasing order, where is the median located?

rusak2 [61]

We have been given that a data set contains 10,000 values arranged in increasing order and we are asked to find where the median of this data will occur.

We know that the median of a data set with even number of entries is found by considering the average of the middle two values.

However, the median of a data set with odd number of entries can be found by considering the middle term of the sequence.

Since the number of entries in our data are 10,000, which happens to be an even number, therefore, we can find the median by computing the average of middle two values.

The middle two values of the data set with 10,000 entries are 5000th and 5001st numbers. Thus, the median of the data set will be average of 5000th and 5001st entries. Hope this helps!
