Answer:
0.45
Step-by-step explanation:
Die 1 is loaded so that only 1, 4, and 6 are possible.
P(1) + P(4) + P(6) = 0.5 + 0.25 + 0.25 = 1
Similarly, Die 2 is loaded so that only 2, 3, and 5 are possible.
P(2) + P(3) + P(5) = 1
0.3 + 0.25 + P(5) = 1
P(5) = 0.45
Answer:
x = 1/2 y = -5/2
Step-by-step explanation:
Since we already know an equation for y, we just need to plug it into the other equation.
21x - 7(-5x) = 28
21x + 35x = 28
56x = 28
x = 1/2
Now that we know x, we substitute it into the other equation, to find y.
y = -5x
y = -5(1/2)
= -5/2
Answer:
164 in^2
Step-by-step explanation:
length = 10 in
breadth = 3 in
height = 4 in
surface area = 2(lb + bh + hl)
=2(10*3 + 3*4 + 4*10)
=2(30 + 12 + 40)
=2*82
=164 in.^2
An equation is a mathmatic expression that has equal signs and an inequality has inequaluty signs example y=12x is an equation and y<12x is an inequality
