Answer:

To find the mode you need to check the number which is more often repeated in the set than the other.But as you can see here there is no number which is repeated more often than the other everyone is repeated once,so in this case we say that the set of data values has no mode.

To find the the range of the set of data you need to first place the numbers in ascending order (as it is already in) and then find the greatest and the smallest number and subtract them.

Range :

10,20,30,40,50,60,70,80,90,100,110,120,130,140,150.

Greatest number = 150.

Smallest number = 10.

Subtract = 150-10 = 140.

A picture frame is 9 inches long and 6 inches wide. It can display a picture 6 inches long and 4 inches wide. What is the area o

nasty-shy [4]

Area of Frame and Picture
Area = L * W
L = 9
W = 6
Area = 9*6 = 54 in²

Area of Picture
Area = L*W
L = 6
W = 4
Area = 6 * 4
Area = 24 in²

Area of Frame
Area of Frame = Total Area - Picture Area
Area of Frame = 54 - 24
Area of Frame = 30 in²

60 percent of a number, minus 17, is -65

Reika [66]

Answer:

We have (60/100)·x - 17 = - 65;

Then (6/10)·x = 17 - 65;

(3/5)·x = - 48;

x = (5/3)·(-48);

x = 5·(-16);

x = - 80;

<h3>Answer: 318</h3>

===============================================

Explanation:

Refer to the diagram below. Notice how I've formed 3 rectangles underneath the curve. The term "right Riemann sum" refers to the idea of making each rectangle's upper right corner be on the curve. The upper left corner spills over top, meaning we have an over-estimate going on here.

Simply find the area of each rectangle, and then add up those sub areas. That will get you to the final answer.

Note how we go from x = -1 to x = 5, which is a distance of 5-(-1) = 6 units. Split three ways and each interval is 6/3 = 2 units wide.

If we started at x = -1, then increasing 2 units leads us to x = -1+2 = 1 as the first x input we compute into f(x). This is the height of the first rectangle.

Then 1+2 = 3 is the next input, meaning f(3) is the height of the next rectangle, and so on. We keep going until all rectangles are accounted for.

----------------------

You should have these rectangle heights:

3
29
127

when moving from left to right.

They add up to 3+29+127 = 159. Double that to get to the final answer of 2*159 = 318

The formula I'm using is

$\Delta x*(f(x_1) + f(x_2) + \dots f(x_n))$

where x1,x2,... represents the values 1, 3, and 5. These are the x values plugged into the function to get the corresponding heights (3, 29, 127)
