Answer:
The difference is 4–3. If you want the difference between 3 and -4, then the difference is 7.
Step-by-step explanation:
Answer:
368 in^2
Step-by-step explanation:
To find the entire surface area, do the following:
Find the area of the base and then multiply it by 2:
(6 in)(5 in)(2) = 60 in^2
Find the area of one side and then mult. it by 2: then find the area of the other side and mult. that by 2 also. Add together these 3 results:
(6 in)(14 in)(2) + (5 in)(14 in)(2) + 60 in^2 = 368 in^2
Its a simultaneous equation:
lets make "x" the used games and "y" the new ones
4x + 2y = 84
6x + y = 78. (multiply this by 2 to cancel out y)
12x + 2y = 156
so now we subtract them:
12x - 4x = 156 - 84
x = 9
used games cost $9
new games cost 78 - 6(9) = $24
Janet has $120 but she already bought 3 NEW games so:
120 - 3(24) = $48 left
48/9 = how many used ones she can buy = 5. something
she can buy 5 used
Answer:
C. y + 3 = 1/2(x - 6)
Step-by-step explanation:
y - y₁ = m(x - x₁)
x₁ = -3
y₁ = 6
m = 1/2
y - (6) = (1/2)(x - (-3))
y - 6 = 1/2(x + 3)
Answer:
Step-by-step explanation:
Given that there are 20 non ionized containers and 73 ionized containers
Two samples are drawn without replacement
a) the probability that the first one selected is not ionized=
b) the probability that the second one selected is not ionized given that the first one was ionized
= When first one was ionized we got left over as 20 and 72
Hence = 
c) If with replacement left over 20 and 73 and hence prob = 0.215 as in part a
d) the probability that both are ionized=
