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
2/ 2/3 *-6 *5 /-3/4
1/2*2/3=2/6= 1/3
1/3 * -6 * 5 / -3/4
1/3* -6= -2
-2*5 / -3/4
-2*5= -10
-10 / -3/4 = -1/10 * -3/4 = 3/40
You can be going the speed limit, 20 mph, or you can be going 20 mph under the speed limit. Which would mean you'd be stationary or not moving.
Answer:The expressions for the payment made to Mary are,
(Monday) 90 = 15m + b
(Tuesday) 62 = 8m + b
where m and b are the fee per student and the base fee, respectively. Solving for m and b, the values are 4 and 30.
The equation that represents Mary's earning is
y = 4x + 30
For 20 students,
y = 4(20) + 30 = 110
For Lisa's earnings,
y = 8x + 15
Substituting 20,
y =8(20) + 15 = 175
Thus, Lisa would earn more than Mary by $65.
