Answer:
6%
Step-by-step explanation:
Let T= truck
C= Car
We are looking for the probability that someone owns a truck given that they own a car
or
P(T|C)
The conditional probability formula is as follows:
P(T|C)=(T∩C)/C
plugging in numbers..
.04/.63=6.3492% which rounds to 6%
1) Let x be the original speed that he was driving;
x mph ---> 1.5 hours
x+44 mph --> 2.5 hours
1.5x + 2.5(x+44)=206
1.5x+2.5x+110=206
4x=206-110
4x=96
x=24
Therefore, he was travelling at 24 mph in the fog.
2) Let x be the speed of 1 snail,
The other snail travels at the speed of x+1 cm/min
23x+23(x+1)=391 <-- solve for x
23x+23x+23=391
46x=368
x=368/46
x=8
Therefore one of the snail travels at 8 cm/min while the other goes at 9 cm/min
7) Let x be one crew
Then the other crew would be working at x+0.5
3.2x+3.2(x0.5)=8 <-- solve for x
3.2x+1.6x=8
4.8x=8
x=8/4.8
x=1.6666 or 1.7 miles
Therefore, one of the crew does 1.7 miles per day and the other crew does (0.5*1.7)=0.85 miles
Hope I helped :)
She was correct to multiply .75 by .15 to get .1125, but she forgot to add that value to .75 to get the total amount of fabric needed.
Answer:
-3s + 6
Step-by-step explanation:
Combine like terms. Like terms are terms with the same amount of the same variables. In this case:
8s - 11s + 6
(8s - 11s) + 6
-3s + 6
-3s + 6 is your answer.
