Answer:
Step-by-step explanation:
mean : added up the values and divide the result by the number of the values
Mr Jones = (5 + 6.25 + 5.75 + 6.50 + 8)/5 = $6.30
Mrs Jones = (5.50 + 7 + 6.25 + 5.75 + 7.75)/5 = $6.45
The difference between the two mean is 15 cents or $0.15
Using product and quotient property:
log x + log y can be displayed as log xy
Because we're subtracting 2 log z we can use the power property to rewrite this as log z^2
Now, using quotient property we can display this expression as:
<h3>log xy/z^2</h3>
about 500
54 is about equal to 50 and 12 is about equal to 10, 50*10 = 500
Answer:
see below
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
5x+60 + 3x-40 = 180
Combine like terms
8x +20 = 180
Subtract 20 from each side
8x+20-20=180-20
8x= 160
Divide by 8
8x/8=160/8
x=20
5x+60 = 5*20+60 = 160
3x-40 = 3*20-40 = 20
