Answer:
0.1538
Step-by-step explanation:
Probability of being dealt with an ace of a 8 =
= Number of ace + number of an 8 in the deck / Total number of cards in the deck
= (4+4) / 52 = 8/52 = 0.1538
Therefore 0.1538 is the required probability here.
21+(5f)=61
Subtract 21 to both sides of the equation
5f=40
Divide both sides by 5
f=8
The answer is 8
Answer:
1) x=14 and y=-3
Step-by-step explanation:
To solve the system of equations, substitute x = -3y+5 into the equation 2x + 8y = 4 for x. This becomes 2(-3y+5) +8y = 4. To solve, apply the distributive property, combine like terms and isolate y.
2(-3y+5)+8y=4
-6y+10+8y=4
10+2y=4
10-10+2y=4-10
2y=-6
y=-3
Then to find x, substitute y =-3 into x =-3y+5.
x = -3(-3) + 5
x = 9 + 5
x = 14
