Answer:
44.81%
Step-by-step explanation:
First determine the z-scores for 3.5 and 5.5 years. After matching the z-scores with the areas under the standard normal curve, subtract the smaller area from the larger area to solve.
Answer:
<h2>x=550/y</h2>
Step-by-step explanation:
The question is incomplete,This is a word problem question, also the second number was not noted in the question.
let the two numbers be x and y
given that
x*y=550
to solve for x we need to divide both sides by y
(x*y)/y= 550/y
The y at the numerator and denominator of the left hand side (LHS) cancels out.
x=550/y
Hence the equation is
x=550/y
Answer:
The daily rate is $33 and the per mile rate is $0.35
Step-by-step explanation:
4x + 440y = 286
3x + 190y = 165.5
We can solve this systems of equations by multiplying the second statement by
to try and eliminate the x variable.
4x + 440y = 286
-4x -
y = -220![\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D)
y= ![\frac{196}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B196%7D%7B3%7D)
560y = 196
y = 0.35
So, the rate per mile is 0.35. Now, with this info, let's find the daily rate by plugging it into the equation.
![4x + 440\cdot0.35 = 286\\4x + 154 = 286\\4x = 132\\x = 33](https://tex.z-dn.net/?f=4x%20%2B%20440%5Ccdot0.35%20%3D%20286%5C%5C4x%20%2B%20154%20%3D%20286%5C%5C4x%20%3D%20132%5C%5Cx%20%3D%2033)
So, the daily rate is $33 and the mile rate is $0.35.
Hope this helped!
