The temp was 4 because of him doing temp
Answer:
x = 50 miles
Step-by-step explanation:
Equation One: y = 40 + 0.2x
Equation Two: y = $1x = x
All you need to do is equate the two ys which represent the total cost for each company. Your question is when are they equal? So make them equal, and you will find out.
x = 40 + 0.2x Subtract 0.2x from both sides of the equation.
x - 0.2x = 40 Combine like terms
0.8x = 40 Divide both sides by 0.8
0.8x/0.8 = 40/0.8
x = 50 miles.
Answer: P (atleast one is careful) is
1 - 0.012 =0.988
B) It is very possible that the result is not valid because the sample may not be representative of the people who use public Wi-Fi
Step-by-step explanation:
P(not careful) =1 - 0.67 = 0.33
P (4 all not careful) = (0.33)^4 =0.012
P (atleast one is careful) = 1 - 0.012 =0.988
A=p (1+I/k)^kn
A future value 160000
p present value ?
I interest rate 6/100=0.06
K compounded semiannual 2
T time 18-7=11years
160000=p (1+0.06/2)^(2×11)
Divide each side by (1+0.06/2)^(2×11)
P=160,000÷(1+0.06÷2)^(2×11)
P=83,502.8
Hope it helps:-)
