The area of the triangle is 270 centimeters. The way that I found that out is the equation 30x18/2
Answer:
x=192/151 , y=312/151 , z= -684/151
Answer:
B) 40
Step-by-step explanation:
<em>Average speed = distance/time</em>
Distance = 12750 km
Time = 13.5 days = 13.5*24 hours = 324 hours
Speed = 12750 km /324 h = 39.4 km/h ≈ 40 km/h
<u>Correct option is</u> B) 40
a) The probability is P = 1/9
b) The probability is P = 1/3.
<h3>
</h3><h3>
How to get the probability?</h3>
First, we need to count the total number of outcomes (different cars that can be made with the given options):
- There are 2 versions (electric and hybrid).
- There are 3 exterior colors (red, blue, green).
- There are 3 interiors (fabric, leather, vinyl)
Then there are 2*3*3 = 18 different cars.
a) Picking a blue hybrid car with an interior that is not leather.
There are 2 cars that meet that condition:
- blue hybrid with fabric.
- blue hybrid with vinyl.
2 out of the 18 cars meet the condition, then the probability is:
P = 2/18 = 1/9
b) picking an electric car in a color other than blue is
The cars that meet the condition are:
- Green electric with any interior (3 options here)
- Red electric with any interior (3 options here)
So 6 out of the 18 cars meet the condition, then the probability is:
P = 6/18 = 1/3
