Regular shapes are shapes that have sides that are all equal and interior angles are also equal.
Irregular shapes are shapes that vary in the measurement of sides and interior angles.
To find the area of an irregular shape, break it down into various regular shape and individually compute its area. Add up all the area of the regular shapes formed from the irregular shape to get the area of the irregular shape.
An example of an irregular shape is the outline of a house.
Pointed roof over a square room. There are two regular shapes found in this irregular shape. A square and a triangle. Compute its individual area and add up these two areas to get the area of the house.
8c-3d is the correct answer
Answer:
(c) 10 phones
Step-by-step explanation:
The mean is the sum divided by the number of contributors:
(12 +10 +9 +5 +14 +10 +10)/7 = 70/7 = 10
The mean number of phones sold for the week was 10 phones.
28 x 2 = 56 half dollar coins
The correlation coefficient is a number that indicates the direction
and closeness of points of a line of best of fit.
So it tells us two things.
It tells us the direction of the line of best fit
and it tells us the closeness of the points.
Usually, anything between -0.9 and -0.6 has a moderate negative correlation. If you look at this on a graph, you will notice that the points definitely resemble a line so we say it's moderate.
It will be a negative correlation because the slope is negative.
