The one with domain {8, 3, 1} and range {6, 2, 7, 9}(top-left) is not a function because 3 is being mapped to two different values, 2 and 7.
Answer:
The percentage of visitors who are truthful clickers and answered yes is 15%.
Step-by-step explanation:
Denote the events as follows:
<em>Y</em> = a visitor clicked Yes.
<em>N</em> = a visitor clicked No.
<em>R</em> = a visitor is a random clicker.
<em>T</em> = a visitor is a truthful clicker.
Given:
The law of total probability states that:
The probability of Y can be computed using the law above as
Compute the value of P (Y|T) as follows:
Percentage = 0.15 × 100 = 15%.
Thus, the percentage of visitors who are truthful clickers and answered yes is 15%.
A. 2 parts is 7, so 7/2 is 3.5 = 1 part, then multiply by 3 to make the corresponding side which is 10.5 or 10 1/2
Answer:
for number one the answer is no for 7 the answer is 5 seconds
Step-by-step explanation:
Let's find the area of each shape that makes up the prism. Let's first start with the triangles.
There are two identical triangles on both ends of the prisms. They have a height of 12 and a base 18. Let's find the area of both of the triangles.
12×18=216
216 is the area of both triangles. Each triangle has an area of 108 though.
Let's find the area of the two rectangles.
There are two identical rectangles that are 30 m by 15 m. Let's find the area of both.
30×15=450×2=900
So, the area of both rectangles together is 900.
Let's find the area of the rectangle that acts as the base in the picture.
There's only one and it's 30 m by 18 m.
30×18=540
Let's add everything together.
540+900+216
1440+216
1656
So, the surface area is 1656 m².
