Answer:
About 400 times
Step-by-step explanation:
Given
See attachment for spinner
Required
Determine the number of times an outcome of 1, 3 or 8 is expected
First, calculate the theoretical probability of 1, 3, or 8
This is calculated as:
The spinner is divided into 8 equal segments and each outcome appears once.
So, we have:
Take LCM and add
So, the expected number of times (E) is:
Approximate
<em>This means about 400 times</em>
Answer:
look at the attached image
Step-by-step explanation:
Part A.
The area of a triangle is given by the product of its base and the height relative to that base.
Since these triangles have the same base b and same height h, they have the same area.
Part B.
The area of a rectangle or parallelogram is given by the product of base and height. Since these figures have the same base and height, they have the same area.
Part C.
These figures have different shapes, so we can't affirm that they have the same area.
Part D.
The height shown in the image is not the height relative to side b, therefore we can't affirm that the triangles have the same area.
X -
x + 4 = -
First, simplify
to
/ Your problem should look like: x -
+ 4 = -
Second, simplify x -
+ 4 to
+ 4 / Your problem should look like:
+ 4 =
Third, regroup terms. / Your problem should look like: 4 -
= -
Fourth, multiply both sides by 2. / Your problem should look like: 8 - x = -1
Fifth, subtract 8 from both sides. / Your problem should look like: -x = -1 - 8
Sixth, simplify -1 - 8 to -9. / Your problem should look like: -x = -9
Seventh, multiply both sides by -1. / Your problem should look like: x = 9
Answer:
x = 9
