To calculate mean: Just add up all the numbers, then divide by how many numbers there are.345 + 673 + 728 +775 + 822 +827 +839 + 951 = 5960/8 = 745
633 + 673 + 728 +775 + 822 +827 +839 + 951 = 6248/8 = 781781- 745 = 35 It increases by 35To find the Median, place the numbers in value order and find the middle. BUT, with an even amount of numbers things are slightly different. In that case we find the middle pair of numbers, and then find the value that is half way between them. This is easily done by adding them together and dividing by two. 345 673 728 775 822 827 839 951 The median = 822-775 /2
The median =23.5After the change633 673 728 775 822 827 839 951 The median = 822-775 /2
The median =23.5The median stays the same.

Answer:

x = 15m

Step-by-step explanation:

The second triangle (large) is 3 times greater than the first triangle (small).

6 x 3 = 18 4 x 3 = 12 5 x 3 = x

5 x 3 is 15, so x is 15m

In the graph shown below, if lines 1^1 are parallel, then the slope of the line 1^2 is?

Galina-37 [17]

Answer:

<h2>Two lines are parallel if the have the same slope. Example 1: Find the slope of the line parallel to the line 4x – 5y = 12. To find the slope of this line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = 12 is m = 4/5.</h2>

Which three values are greater than

solniwko [45]

Answer:

3/4 is greater than 1/2

45% = 9/20 is less than 1/2

1/3 is less than 1/2

0.62 is greater than 1/2

59% = 59/100 is greater than 1/2

0.315 is less than 1/2

So, A, D and E are greater than 1/2

Hope this helps!

Using linear function concepts, it is found that:

a) The initial value is of 3 and the rate of change is of 20.

b) The rate of change means that for <u>each hour, the cost increases by 3 Dhs</u>, while the initial value means that <u>a flat fee of 20 Dhs is paid</u>.

<h3>What is a linear function?</h3>

A linear function is modeled by:

$y = mx + b$

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.

b is the y-intercept, which is the value of y when x = 0, and also can be considered as the initial value.

In this problem, the function that gives the charge C for renting a bicycle for h hours is:

$C(h) = 3h + 20$

Item a:

Comparing to the standard function, we have that:

The initial value is of 3 and the rate of change is of 20.

Item b:

The rate of change means that for <u>each hour, the cost increases by 3 Dhs</u>, while the initial value means that <u>a flat fee of 20 Dhs is paid</u>.
