Step-by-step explanation:
Answer:
Therefore, Michael concludes option C)
C)
Step-by-step explanation:
Given:
1. DG = 3 and the area of square DEFG is 9.
2. AG = 4 and the area of square GHIA is 16.
3. DA = 5 and the area of square ABCD is 25.
So we have,
Now Add DG² and AG² we get
Which is also called as Pythagoras theorem i.e
Therefore, Michael concludes option C)
C)
Using the binomial distribution, it is found that there is a 0.9842 = 98.42% probability that 3 or fewer experienced insomnia as a side effect, which means that it is a highly likely event.
<h3>What is the binomial distribution formula?</h3>
The formula is:
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
The values of the parameters are given as follows:
n = 20, p = 0.05.
The probability that 3 or fewer experienced insomnia as a side effect is given by:
Hence:
Then:
0.9842 = 98.42% probability that 3 or fewer experienced insomnia as a side effect.
Since this probability is greater than 95%, this is a highly likely event.

SA of a sphere is 4πr² Using a sample of radius 3 the SA would be 36π²
(4πx3²) If we double the radius and make it 6, the SA would be 144π²
So for Surface area, your classmate is correct.
What about the volume? V of a Sphere = 4/3 π r³
Again using 3 the Volume of a Sphere with radius 3 = 4/3 π 27
But the volume of a sphere with radius 6 = 4/3 π 216 which is eight times the volume of the smaller sphere. (27 x 8 =216) So your friend is right about Surface Area but wrong about the volume.
Answer:
9 cm
Step-by-step explanation:
r² = 3×V/π×h
= 3× 459π/(π×17)
= 81
r= √81= 9
