Answer:
1/52
Step-by-step explanation:
We are given that
Total number of cards=52
Number of cards of 4 of spade=1
We have to find the probability of choosing the "4 of spades".
We know that
Probability, P(E)=
Using the formula
The probability of getting 4 of spade=
Hence, the probability of choosing the "4 of spades"=1/52
Answer: 13 hours
Step-by-step explanation:
The scenario that is being described can be fully made into an equation using three variables. These would be w for the number of weeks, b for the number of hours she babysat that week, and x for the total amount of hours worked. Like so...
5w + t = x
Since we are told that we need to find the total hours worked for a single week (w = 1) and that Erica babysat for 8 hours that week (b = 8), then we only need to solve for the total amount of hours worked (x)
5(1) + 8 = x
5+8 = x
13 = x
Erica worked a total of 13 hours.

2 + 17x - 5x + 9
First, subtract 17x - 5x to get 12x.
Second, leave the 12x be and add 2 + 9 to get 11.
Answer:
12x + 11
Answer:
C) 3x - 4y = 7
Step-by-step explanation:
The midpoint of AB is
M( (-2 + 4)/2, (-5 + 3)/2 ) = M(1, -1)
Line AB has slope:
(3 - (-5))/(-2 - 4) = 8/(-6) = -4/3
Slopes of perpendicular lines are negative reciprocals.
A perpendicular to line AB has slope 3/4.
The perpendicular to line AB that passes through the midpoint of segment AB is the line we want.
