ZanzabumX [31]
8 1-and-a-half blocks would be 12 blocks, and so 12/17, because 12 blocks in 17 mins., so you divide 12 by 17 to get ---- blocks per minute, which is 12/17 as a fraction, or approx. 0.705882353 blocks per minute.

Construct a sample (with at least two different values in the set) of 4 measurements whose mean, median, and mode are equal. If
KiRa [710]

Answer:

The first set 4 , 6 , 6 , 8

The second set 2 , 6 , 6 , 10

Step-by-step explanation:

Mean is the average of the values in a set. This can be found by summing all the numbers and dividing by the total number. The median is the middle number when the values are listed in order of increasing size. The mode is the number(s) that appear the most often in the set.

The first set 4 , 6 , 6 , 8

mean = (4 + 6 + 6 + 8 )/4 = 6

median = (6+6)/2 = 6

Mode = 6

The second set 2 , 6 , 6 , 10

mean = (2 + 6 + 6 + 10)/4 = 6

median = (6+6)/2 = 6

Mode = 6

One week a computer store sold a total of 36 computers and external hard drives. the revenue from these sales was ​$30875 . if c
melamori03 [73]

To solve this problem you must apply the proccedure shown below:

1. You must make a system of equation by using the information given in the problem above. Then, let's call:

x: The number of computers sold.

y: The number of hard drives sold.

2. Therefore, you have the following system of equations:

\left \{ {{x+y=36} \atop {1180x+125y=30875}} \right.

2. Solve for x in the first equation and substitute it into the second equation:

x=36-y\\ 1180(36-y)+125y=30875

3. Solve for y:

42480-1180y+125y=30875\\ y=11

4. Substitute the value of y into the first equation to calculate x:

x+11=36\\ x=25

Therefore, the answer is: The store sold 25 computers and 11 hard drives.
