Answer: The mean for the probability distribution will be 69.25.
Explanation:
Since we given that
As we know the formula for expectation of x i.e. known as mean for the probability distribution,
So, we apply this formula in our case,
Hence, the mean for the probability distribution will be 69.25.

Answer:
30°
Step-by-step explanation:
The relationship between triangle sides and angles can be remembered using the mnemonic SOH CAH TOA. Here, we're interested in the relationship involving the hypotenuse and the side opposite the angle:
Sin = Opposite/Hypotenuse
For a ramp 1 m high and 2 m long, we have ...
sin(x) = (1 m)/(2 m) = 1/2
x = arcsin(1/2) = 30°
The elevation angle of the ramp needs to be 30°.
Answer:
Yes
Step-by-step explanation:
1.2 is rational
Answer:
20 m^2
Step-by-step explanation:
First multiply the parallelogram part: 3 x 5 = 15
Then multiply the triangle part: (2 x 5)/2 =5
Then add: 15 + 5 = 20
Good Luck!
