18 to 4, and 18/4 those are the only two I could think of
Answer:
2. x = (y - 1)² + 4
<u>Step-by-step explanation:</u>
Notes: The vertex form of a parabola is y = a(x - h)² + k or x = a(y - k)² + h
- (h, k) is the vertex
- p is the distance from the vertex to the focus
1)
Now input a = -1/2 and (h, k) = (9, 10) into the equation y = a(x - h)² + k
*****************************************************************************************
2)
Now input a = 1 and (h, k) = (4, 1) into the equation x = a(y - k)² + h
x = 1(y - 1)² + 4 → x = (y - 1)² + 4
*****************************************************************************************
3)
Now input a = 1/2 and (h, k) = (7, 2) into the equation x = a(y - k)² + h
Answer:
a) 81.5%
b) 95%
c) 75%
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 266 days
Standard Deviation, σ = 15 days
We are given that the distribution of length of human pregnancies is a bell shaped distribution that is a normal distribution.
Formula:
a) P(between 236 and 281 days)
b) a) P(last between 236 and 296)
c) If the data is not normally distributed.
Then, according to Chebyshev's theorem, at least data lies within k standard deviation of mean.
For k = 2
Atleast 75% of data lies within two standard deviation for a non normal data.
Thus, atleast 75% of pregnancies last between 236 and 296 days approximately.
