probability is the answer for sure
Answer:
Since x is an integer we conclude that there are 10 trucks needed to carry away 45 tones of debris.
Step-by-step explanation:
First we will find the volume of the dump truck:
V = 10*15*6.5
V = 975 ft^3
1 ton = 200 ft^3
45 tons = 45*200 ft^3
45 tons = 9,000 ft^3
Let x represent the number of trucks needed to carry away 45 tones of debris:
975*x = 9000
Answer:
m= -4/3
Step-by-step explanation:
add 10m to each side and subtract 1 from both sides to change the equation to 15m=-20. Then divide 15 from both sides to get m alone. You will end up with -4/3
Answer:
f (
x
) −
1 =
(
1/
4 x
) −
2.
Step-by-step explanation:
For inverse function, the x and y interchanges and then make y the subject again of the equation. See the working out below:
f (
x
) = 4
x + 8
f (
x
) = y
y = 4
x + 8
x = 4
y +
8 ----- interchanging y and x
Now make y the subject of the equation:
x = 4
y + 8
−
4
y = -
x + 8
y = (
−
1/
4 )
. − x
+ (
−
1/
4 ) .8
y = (
1/
4 x
) −
2
So the inverse function is:
f (x) −
1 = (
1/
4 x
) −
2
Answer:
1/12
Step-by-step explanation:
P( coin = heads) = number of heads / total = 1/2
P( cube = 5) = number of 5's / total =1/6
P( heads, 5) =1/2 * 1/6 = 1/12
