Answer:
20 ; $135 ; service charge for 3 hours spent is $135
Step-by-step explanation:
Given that :
Service fee equation model :
C(h)= 75 + 20h
C = total cost of the service call
h = number of hours the plumber spends working on the problem
The charge per hour is the gradient or slope of the linear equation. From the equation, the slope is of the equation is related to bx from. The general form of a linear equation where b = gradient or slope(charge per hour) and x = number of hours
bx = 20h
b = 20
Charge per hour = 20
C(3) = 75 + 20(3)
75 + 60 = 135
This means that total service call charge for a plumber who spends three hours fixing a problem is $135
2(5-6)<8f-130
(2x5)-(2x6)<8f-130
10-12<8f-130
-2<8f-130
-2+130<8f-130+130
128<8f
128/8<8f/8
16<f
f>16
Step-by-step explanation:
x=90°
SUM OF ALL ANGLES OF PENTAGON =540
90+2(180-Y)+105+113=540
90+360-2Y+105+113=540
488-2Y=540
Answer:
Step-by-step explanation:
A -> Rolling a sum of 6 (Can occur with (1,5), (5,1), (3,3), (2,4), (4,2)
B -> Rolling Doubles (Can occur in 6 different ways)
P(A) = 5/36
P(B) = 6/36 = 1/6
P(A)*P(B) = (5/36)*(1/36)
= 5/1296
P(A∩B) = 1/36 (This only happens when (3,3) is rolled
In this case,
P(A)*P(B) =/= P(A∩B)
Hence, they are not independent, which means that their occurence affects the others' probability.
