Answer:
nope
Step-by-step explanation:
The standard deviation is 1.98. Option A is correct.
The standard deviation formula is given as
where:
- SS is the sum of squares = 200
- n is the sample size = 51
Substitute the given parameters into the formula to have:
Hence the standard deviation is 1.98

Answer:
x != -2, x^2 + 1, 1/5
Step-by-step explanation:
(a) It can be understood that nothing can divide 0
thus denominator cannot be 0 meaning x cannot be -2.
(-2 + 2) = 0
(b) y = sqrt(x-1)
inverse meaning we make x the subject
square both sides
y^2 = x - 1
y^2 + 1 = x
inverse = x^2 + 1
(c) composite function:
pass g(10) as domain of f
g(10) = 3, f(3) = 1/(5) = 1/5

Hello!
The person started working at 8:30 and stopped at 11:45 for lunch. That means that person worked 1 hour and 15 minutes before taking a lunch break.
The lunch break doesn't count because the person wasn't "working" then.
Next, this person worked from 12:30 to 5:15, which means they worked 4 hours and 45 minutes.
Add this up with the 1 hour and 15 minutes from before:
4 h 45 min + 1 h 15 min = 6 hours
This person worked a total of 6 hours.
