15=-4+z/3
+4 +15 = +4 -4 +z/3
cancels the 4 on the right side
19 = z/3
3 x 19 = z/3 x 3
cancels 3 on the right side
I think the answer is z = 57
Answer:
<h3>The surface area of the prism is A prism=204m2</h3>
Step-by-step explanation:
Area is the space that is contained in a two-dimensional figure.
Surface area is the total area of all of the sides and faces of a three-dimensional figure.
To find the surface area, the area of each face is calculated and then add these areas together.
To find the area of a rectangle, multiply the length by the width .
From the graph the length of the rectangle is 10 m and the width is 8 m. Therefore, the area of the bottom face is
From the graph the length of the rectangle is 10 m and the width is 5 m. Therefore, the area of one of the rectangular side faces is
To find the area of a triangle use the following formula where b is the base and h is the height.
From the graph the base of the triangle is 8 m and the height is 3 m. Therefore, the area of one of the triangular faces is
The surface area of the prism is the sum of the area of the bottom face, the area of the two rectangular side faces, and the area of the two triangular faces

Answer:
The correct answer is D. It is not true that cluster sampling uses randomly selected clusters and samples everyone within each cluster.
Step-by-step explanation:
Cluster sampling is a method of collecting samples and statistical data, by means of which a certain group formed by people, things, events, etc., is taken as a sample, which are not considered individually but as part of a whole, which is in turn a proportional representation of the universality of samples available in the field.
Now, since this type of sampling allows to embrace large groups of sample units, data are not always obtained from all the components of the cluster, but from those necessary to be able to quantify the desired statistics.
A perpendicular bisector cuts a line segment directly in half. a property of perpendicular bisectors is that any point on the line of the bisector will be equidistant (the same distance from) both end points.
Ex, If point X was 5 ft away from one endpoint, it would be 5 feet away from the other as well.
