I need to know how to do the work for this problem! I'm so stuck please help!

Answers

Mean = $65.85
S.D. = $36
For 1 s.d.: 65.85 - 36 ≤ x ≤65.85 + 36 => 29.85 ≤ x ≤ 101.85
But $25.60 and $126.40 does not fall within 1 standard deviation.
Therefore, all the prices fall within 2 standard deviations.

Mean = (146 + 189 + 246 + 178 + 203)/5 = 192.4
S.D. = sqrt[(146 - 192.4)^2 + (189 - 192.4)^2 + (246 - 192.4)^2 + (178 - 192.4)^2 + (203 - 192.4)^2] = 73.2
For 1 S.D.: 192.4 - 73.2 ≤ x ≤ 192.4 + 73.2 => 119.2 ≤ x ≤ 265.6
All the weight falls within 1 standard deviation of the mean.

One of the corners of a cube is sliced off. The resulting cross section will have a minimum of how many sides?

Answers

3, because you cut a corner, you cut through where 3 sides meet.

3 sides

Answer:

The resulting cross-section will have a minimum of three sides.

i.e. a triangle will be formed.

Step-by-step explanation:

Because on cutting a cube along the corner we will obtain a triangle and thus a triangle has three sides.

Hence, the resulting cross section will have minimum of three sides.

( Also we can obtain many other figures on slicing a cube in different ways.

If we slice a cube parallel to the base we will obtain a square.

when we will slice the cube to it's diagonal we will obtain a rectangle.

and in many other ways)

Which statement is true regarding the graphed functions?f(0) = 2 and g(–2) = 0
f(0) = 4 and g(–2) = 4
f(2) = 0 and g(–2) = 0
f(–2) = 0 and g(–2) = 0

Answers

Answer:

C. f(2) = 0, and g(-2) = 0

Step-by-step Explanation:

From the graph given, the line for f(x) and g(x) intercept each other at x = 0, when y = 4, that is f(0) = 4 and also g(0) = 4.

From the graph, on the line of g(x), when x = -2, y = 0, that is g(-2) = 0.

Also for f(x), when x = 2, y = 0. That is, f(2) = 0.

Therefore, the statement that is true about the graphed function is:

f(2) = 0, and g(-2) = 0

If both the base and height of a triangle are made nine times as long, how many times the area of the original figure is the area of the new figure?

Answers

To start: A = 1/2bh
Now by increasing both the width and height by 9, you get: A = 1/2(9b)(9h) = 1/2(81)bh

You can see that the increase in area is 81 times the original.
