Answer:
Option B) is a continuous probability distribution
Step-by-step explanation:
Properties of a normal probability distribution:
- The mean, mode and median of the data is same.
- It is a continuous probability distribution.
- The area under the curve is 1.
- The probability that any random variable X at a particular value is zero.
Thus, from the properties of normal distribution, the correct answer is:
Option B) is a continuous probability distribution
Answer:
11. ∠B ∠ABC ∠CBA ∠2
17. QR = 12
Step-by-step explanation:
11. ∠B ∠ABC ∠CBA ∠2
17. Given: PS = 18 PR = 15 PQ ≅ RS
It would be good if you could draw a picture for yourself
So, RS = PS - PR
= 18 - 15 = 3
RS = PQ = 3
QR = PS - RS - PQ
= 18 - 3 - 3
= 12
Answer:
8.66 m
Step-by-step explanation:
Given that,
The distance from the top of the building to the tip of the shadow is 14 m
The height of the building is 11 m.
We need to find the length of the shadow. we can see that the length of the shadow forms the base of the triangle.
The distance from the top of the building to the tip of the shadow form hypotensue and height of the building forms perpendicular. So, we can use Pythagoras theorem to find the base.
So,
So, the length of the shadow is 8.66 m.
