Answer:
y + 1 = 4(x + 3)
Step-by-step explanation:
Use the point-slope form of the equation of a straight line:
y - k = m(x - h), where (h,k) is a point on the line:
Here,
y + 1 = 4(x+3) (Answer 2 on the list)
3.54 • 10*-2
Step-by-Step Solution:
Place the decimal point after the first non-zero number, and multiply by 10 to the appropriate power I.e., how many places you would need to move the decimal to get the original number.
Answer:
a) 0.8413
b) 421
c) ![P_{95} = 189.675](https://tex.z-dn.net/?f=P_%7B95%7D%20%3D%20189.675)
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 165
Standard Deviation, σ = 15
We are given that the distribution of IQ examination scores is a bell shaped distribution that is a normal distribution.
Formula:
a) P(IQ scores at most 180)
P(x < 180)
Calculation the value from standard normal z table, we have,
b) Number of the members of the club have IQ scores at most 180
n = 500
![\text{Members} = n\times \text{P(IQ scores at most 180)}\\= 500\times 0.8413\\=420.65 \approc 421](https://tex.z-dn.net/?f=%5Ctext%7BMembers%7D%20%3D%20n%5Ctimes%20%5Ctext%7BP%28IQ%20scores%20at%20most%20180%29%7D%5C%5C%3D%20500%5Ctimes%200.8413%5C%5C%3D420.65%20%5Capproc%20421)
c) P(X< x) = 0.95
We have to find the value of x such that the probability is 0.95
Calculation the value from standard normal z table, we have,
![P(z < 1.645) = 0.95](https://tex.z-dn.net/?f=P%28z%20%3C%201.645%29%20%3D%200.95)
![P_{95} = 189.675](https://tex.z-dn.net/?f=P_%7B95%7D%20%3D%20189.675)
Answer:
Equation
