Answer:
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 64
Sample mean = 22.3
Sample standard deviation = 8.8
We want to estimate 92% confidence interval.
92% Confidence interval:
Putting the values, we get,
Degree of freedom = n - 1 = 63
The mistake done is in multiplying the numerator values after Taking LCM.
Correct answer is
Step-by-step explanation:
We will first solve the expression and then identify the error.
Solving:
Finding LCM of (x-2) and (x+1) we get (x-2)(x+1)
So, the mistake done is in multiplying the numerator values after Taking LCM. x+1-(x-2) we get x+1-x+2 because (-)*(-) = + and (-)*(+)= -. So, we get
x-x+1+2 we know that x-x=0 and 1+2=3
So, correct answer is

Given
d(t)=-16t^2-4t+382
1. times at which rock is 310 from ground
solve d(t)=310=-16t^2-4t+382
=>
16t^2+4t-72=0
t=(-4+/-sqrt(4^2+4*16*72)/(2*16)
=> t=-9/4 or t=2
Reject negative root from context, so
time=2 seconds.
2.
maximum is when d'(t)=0, or
-32t-4=0 => t=-1/8
Therefore rock was descending since t=0 (can also see from -4t, i.e. initial velocity is -4 ft/s)
Rock reaches ground when d(t)=0, i.e.
-16t^2-4t+382=0
t=-5.01 or t=4.763 seconds. reject negative root.
Therefore, domain, t=0 to 4.763 seconds
range = 0 to 382 ft
