Answer: y = x + 1
Step-by-step explanation:
y = 1x + c
-7 = 1(-8) + c
-7 = -8 + c
-7 + 8 = c
1 = c
y = 1x + 1 or
y = x + 1
Answer:
V=12
Step-by-step explanation:
Faces: 20 Edges: 30
Write the Euler's formula for 3-dimensional figures
F+V=E+2
Substitute some variables for their known values
20+V=30+2
Add the numbers on the right side of the equation
20+v=32
Subtract 20 on both sides
20-20+V=32-20
Subtract
V=32-20
Number of Vertices
V=12
Answer:

Step-by-step explanation:
Given

The equation of the perpendicular bisector.
First, calculate the midpoint of the given endpoints



Open bracket


Next, determine the slope of the given endpoints.




Next, calculate the slope of the perpendicular bisector.
When two lines are perpendicular, the relationship between them is:

In this case:

So:


Since the slope is
, the equation is:

Where:

Recall that:

So:

Hence, the equation is:

Using it's concept, it is found that the probability of a person being over 20 years old and preferring strawberry ice cream is of 12%.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes.</u>
In this problem, there are 8 + 10 + 6 + 8 + 6 + 12 = 50 people, and of those, 6 are over 20 years old and prefer strawberry ice cream, hence the probability is given by:
p = 6/50 = 0.12 = 12%.

Answer:
12.5 un^2
Step-by-step explanation:
The formula for area of a trapezoid is (a+b)/2 *h
a and b are the shorter and longer bases respectively. H is height, you have both.
Simply plug it into the equation and find your answer.
(2.5+7.5)/2 *2.5 = 5*2.5 which is equal to 12.5. Add units.
