Answer:
5,070.3
Step-by-step explanation:
Answer:
The z-score is 2.5106 which is an unusual value of z-score as it is greater than 2.00
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 161 pounds
Standard Deviation, σ = 23.5 pounds
x = 220 pounds
Formula:
Putting values, we get,
Thus, the z-score is 2.5106 which is an unusual value of z-score as it is greater than 2.00
Answer:
<h2>(f o g)(4) = - 49</h2>
Step-by-step explanation:
F(x) = 3x - 7
g(x) = -2x - 6
To find (f o g)(4) we must first find (f o g)(x)
To find (f o g)(x) substitute g(x) into f(x) that's for every x in f (x) replace it with
g (x).
We have
(f o g)(x) = 3( - 2x - 6) - 7
= - 6x - 18 - 7
We have
(f o g)(x) = - 6x - 25
To find (f o g)(4), substitute the value of x that's 4 into (f o g)(x)
We have
(f o g)(4) = - 6(4) - 25
= - 24 - 25
We have the final answer as
<h3>(f o g)(4) = - 49</h3>
Hope this helps you
The first step to solving this is to solve the equation for x
x = - 21/5 - y
4x + 4y = -14
now,, substitute the given value of x into the equation "4x + 4y = -14"
4( - 21/5 - y) + 4y = -14
next,, solve the equation for y
y∈∅
since this system has no solution for y, your answer is (x,y)∈∅

It’s either -538 or +538 depends the circumstances
