Answer:
Below is the R code for the bootstrapping in exponential distribution. The result is attached below.
####################################
rm(list=ls(all=TRUE))
set.seed(12345)
N=c(10,100,500)
Rate=0.2
B=1000
MN=SE=rep()
for(i in 1:length(N))
{
n=N[i]
X=rexp(n,rate=Rate)
EST=1/mean(X)
ESTh=rep()
for(j in 1:B)
{
Xh=rexp(n,rate=EST)
ESTh[j]=1/mean(Xh)
}
MN[i]=mean(ESTh)
SE[i]=sd(ESTh)
}
cbind(N,Rate,MN,SE)
Step-by-step explanation:
8x+100 with x representing the number of classes attended. For Ms.Wiggins, the equation would be 8(18)+100. You would multiple 8 x 18 getting 144+100. You add 144+100 to get $244 for Ms.Wiggins.
Answer:
B
Step-by-step explanation:
We require 2 equations in 2 variables
let x be the number of salads sold and y the number of drinks sold, then the 2 equations are
x + y = 209 → (1)
6.5x + 2y = 836.5 → (2)
Multiplying (1) by - 2 and adding to (2) will eliminate y
- 2x - 2y = - 418 → (3)
Add (2) and (3) term by term
(6.5x - 2x) + (2y - 2y) = (836.5 - 418) ← simplify
4.5x = 418.5 ( divide both sides by 4.5 )
x = 93
The number of salads sold was 93
