Answer:
1) Newbury Park → The distance is accurate.
2) Thousand Oaks → The distance is not accurate.
3) Los Angeles → The distance is not accurate.
Step-by-step explanation:
It is important to remember that:
Knowing this, you can make the corresponding conversions:
1) Newbury Park
10 miles to kilometers:
The distance shown in that California highway sign is accurate.
2) Thousand Oaks
13 miles to kilometers:
The distance shown in that California highway sign is not accurate.
3) Los Angeles
55 miles to kilometers:
The distance shown in that California highway sign is not accurate.
Answer:
0.336
Step-by-step explanation:
Use binomial probability:
P = nCr p^r q^(n-r)
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1-p).
Here, n = 8, r = 7, p = 0.8, and q = 0.2.
P = ₈C₇ (0.8)⁷ (0.2)⁸⁻⁷
P = 0.336
So a pentagon is constructed by five identical triangles, that's why you can find the area of one triangle and multiply it with 5:
A_pentagon=A_triangle*5
To find the area of a triangle you must use tangens.
You can watch this for more on that on youtube.
For the length of an arc or a portion of a circle you can find it using:
arc lenght = 2π*r(A/360), where A=angle.
So if you know radians, then 2π is a whole circle. And to calculate for the specific circle you have to use the radius. That's why you multiply with radius, which is the only difference between any two different circles. you then multiply with the part of the circle that you want to find the lenght for, which is A/360 (because there are 360° in a circle)
I hope that helped.
