Answer:
Sammy charges less by $3.75
Step-by-step explanation:
givens
-Sammy: 21.75 for 3 hrs
-y=8x for Claire
-5 hours, and who charges less?
21.75/3
$7.25/hr
y=8(5)
y=$40
y=7.25(5)
y=$36.25
40-36.25
$3.75

Two <em>possible answers</em> are:
5/16 and 3/8.
Explanation:
To create a fraction equivalent to a given fraction, you multiply the numerator and denominator by the same number. This means for 5/8, we could have:
5/8; (5*2)/(8*2)=10/16; (5*3)/(8*3)=15/24; etc.
For 1/2, we could have:
1/2; (1*2)/(2*2)=2/4; (1*3)/(2*3)=3/6; etc.
Μ = 500, population mean
σ = 110, population stadard deviation
The given table is
z 0.00 0.25 0.35 0.45 1.00 1.26 1.35 1.36
P 0.5000 0.5987 0.6368 0.6736 0.8413 0.8961 0.9115 0.9131
Range of random variable is X = [350, 550].
Calculate z-score for x = 350.
z = (350 - 500)/110 = -1.364
From the given tables,
The probability at x = 350 is
1 - 9131 = 0.0869
Calculate the z-score for x = 550.
z = (550 - 500)/110 = 0.454
From the given tables,
The probability at x = 550 is 0.6736
The probability that x =[350,550] is
0.6736 - 0.0869 = 0.5867
Answer: 0.5867 (or 58.7%)
Mark spent a total of 80 minutes or 1 hour and 20 minutes traveling to and from work.
