Expression for g is g = 4πl/T²
Step-by-step explanation:
- Step 1: Fing g from the given expression T = 2π. Firstly, square the expression to find g.
⇒ T² = 4π²
⇒ gT² = 4πl
⇒ g = 4πl/T²
Answer: 7.2ft not sure if ur rounding answers. If nearest whole number than 7ft.
Step-by-step explanation:
Use Pythagorean theorem.
4^2 + 6^2 = c^2
16 + 36 = 52 = c^2
C = 7.2ft
N=400
sample proportion >= .475 => n>=.475N=190
mean response rate of population, p=0.5
Problem satisfies criteria for binomial distribution, where
P(x>=190)=sum P(x=i), i=190 to 400
This can be obtained from binomial distribution tables, calculators, or software as
P(x>=190)=1-P(x<190)=1-0.14685=0.85315
Alternatively, normal approximation can be used.
mean=Np=400*.5=200
variance=Npq=400(.5)(1-.5)=100
standard deviation=sqrt(variance)=sqrt(100)=10
Calculate P(X>=190)=1-P(X<190)
X with continuity correction = 189.5
Z=(X-mean)/standard deviation=(189.5-200)/10=-1.05
P(z<Z)=P(z<-1.05)=0.14686 (from normal probability tables)
hence
P(X>=190)=1-P(X<190)=1-P(z<-1.05)=1-0.14686=0.85314 (approximately)
almost same as the exact binomial solution.
The answer is x=4 and y=13
