Answer:
B ; C ; D
Step-by-step explanation:
Number of faces on a number cube = 6
Sample space = (1, 2, 3, 4, 5, 6)
P(1 then 0)
P(1) = 1/6 ; P(0) = 0
P(1 then 0) = 1/6 * 0 = 0
P(even number then odd number) :
P(even number) = 3/6 = 1/2
P(odd) = 3/6 = 1/2
P(even number then odd number) = 1/2 * 1/2 = 1/4
P(6 then 2) :
P(6) = 1/6 ; P(2) = 1/6 = 1/2
P(6 then 2) = 1/6 * 1/6 = 1/36
P(even number then 5) :
P(even) = 3/6 = 1/2
P(5) = 1/6
P(even number then 5) = 1/2 * 1/6 = 1/12
P(odd number then 2) :
P(odd) = 3/6 = 1/2
P(2) = 1/6
P(odd number then 2) = 1/2 * 1/6 = 1/12
Answer:
2x + y = 3.75
3x + 2y = 6
Step-by-step explanation:
x = cost of 1 hot dog
y = cost of 1 drink
Neveah: 2x + y = 3.75
Jason: 3x + 2y = 6
Answer:
512
Step-by-step explanation:
∛n = 8
n = 512
double check
∛512 = ∛(8)^3 = 8
3x-6y=2 (label equation 1)
5x+4y=1 (label equation 2)
-6y=-3x+2 (rearranged equation 1)
y=1/2x-1/3 (label equation 3)
substitute equation 3 into equation 2
5x+4(1/2x-1/3)=1
5x+2x-4/3=1
15x+6x-4=3 (multiplied everything by 3)
21x-4=3
+4 +4
21x=7
x= 7/21
x=1/3
sub x=7/21 into equation 3
y= 1/2(1/3) -1/3
y= -1/6
Therefore x=1/3 and y= -1/6
Answer: $44,518
Step-by-step explanation:
Using the formula:
PV = P( )
PV = present value
P = Principal
r = rate
n = number of periods
From the question :
PV = ?
P = $10,000
r = 0.04
n = 5
Substituting into the formula , we have
PV = 10,000 ( )
PV = 10,000 ( )
PV = 10,000 (
PV = 10,000 ( 4.451822331 )
PV = 44518.22331
Therefore :
PV≈ $ 44,518
