Answer:

The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers. The "median" is the "middle" value in the list of numbers

Step-by-step explanation: The mean of a data set is equal to the sum

of the set of number divided by how many numbers are in the set.

The mean is often referred to as the <em>average</em>.

The median is the middle number in the data set

when the data set is written from least to greatest.

A raft and a motorboat simultaneously leave from the same point and move down the river. After 2 hours the motorboat turns aroun
lesya692 [45]

Answer:

2 hours

Step-by-step explanation:

Let x mph be the speed of motorboat in still water and y mph be the speed of current.

A raft and a motorboat simultaneously leave from the same point and move down the river, then speeds down the river are:

        motorboat =  x + y mph

        raft = y mph

In two hours they will cover:

        motorboat = 2(x+y) miles

        raft = 2y miles

After 2 hours the motorboat turns around and starts moving towards the raft (against the current), so its speed is now x - y mph.

Let t be the time they move towards each other. In t hours, they cover

        motorboat = t(x - y) miles

        raft = ty miles

The distance from the starting point to the turning point is the same as the sum of the distances the raft covers and the motorboat covers after turning around, so

2(x+y)=2y+t(x-y)+ty \\ \\2x+2y=2y+tx-ty+ty\\ \\2x=tx\\ \\t=2\ hours

Given the figure below, find the values of x and z.
bulgar [2K]

Answer:

x = 12

z = 101

Step-by-step explanation:

Hello There!

First lets find z

Well the angle that has a measure of 79 degrees and angle z are supplementary angles meaning that the sum of the two is 180

So we can find the missing angle by subtract the given angle (79 in this case) from 180

180 - 79 = 101 so z = 101

Now lets find x

The angle that has a measure of 79 degrees and the angle labeled (6x+7) are vertical angles

If you didn't know vertical angles are congruent

That being said lets create an equation to solve for x

79 = 6x + 7

now we solve for x

step 1 subtract 7 from each side by

7 - 7 cancels out

79 - 7 = 72

now we have 72 = 6x

step 2 divide each side by 6

72/6=12

6x/6=x

we're left with x = 12

Which System of Inequalities could be used to solve the problem below?
SCORPION-xisa [38]

a+y≤1000 and 25a+12.50y>15000 is the system of inequalities that could be used to solve the problem.

Step-by-step explanation:

Given,

Price of one adult ticket = a = $25

Price of one youth ticket = y = $12.50

Maximum people that can be hold by theater = 1000

Therefore;

The maximum number of people can be 1000 or less than that.

a+y\leq 1000

As they want to revenue to be more than 15,000 therefore,

25a+12.50y>15000

a+y≤1000 and 25a+12.50y>15000 is the system of inequalities that could be used to solve the problem.
