E^2x=(42-12)/3, that is easy
Then, the magic!
Ln(e^2x)=Ln[(42-12)/3]
2x.Ln(e)=Ln[(42-12)/3]. "Ln(e)=1"
X={Ln[(42-12)/3]}/2
Good luck!

Answer:

A bus travels with a constant speed of 48 miles per hour. How long will it take to travel 60 miles?

Step-by-step explanation:

Mostly it's 1.25 hours </3 Since distance = rate times , or d = rt, then we have

t = d/r = 60 miles / 48 mph = 1.25 hours = 1 hour 15 minutes

either 1 hour 15 mins or 1hour and 25 mins.

Answer: 0.6274

Step-by-step explanation:

Given: The proportion of patients experience injection-site reactions with the current needle : p=0.11

Sample size : n= 4

Let x be a binomial random variable that represents the people get an injection-site reaction.

Binomial probability formula: $P(X=x)= ^nC_x p^x(1-p)^{n-x}$

The required probability : P(x=0)

$=\ ^4C_0(0.11)^0(1-0.11)^4\\\\=(1)(1)(0.89)^4\\\\=0.62742241\\\approx0.6274$

Hence, the probability that none of the 4 people get an injection-site reaction = 0.6274
