It's an overcast day in Hayward and you're waiting for AC Transit 97 Bus Line to show up. Your weather app says there's a 30% chance of rain that day. You know that if it rains, the probability that the bus runs late is 40%. If it doesn't rain, the probability that the bus runs late is only 15%. Use proper notation to state the probabilities. (a) What is the probability that it will rain and the bus will be late? (b) What is the probability that the bus will be late? (c) Given that the bus ran late, what was the probability that it was not raining?
Answer:
a
[tex]P(r n L) = 0.12[/tex]
b
[tex]P(L) = 0.225[/tex]
c
[tex]P(\= r | L) = 0.4667 [/tex]
Step-by-step explanation:
The chance that it will rain is [tex]P(r ) = 0.30 [/tex]
The chance that it does not rain is [tex]P(\= r ) = 1 - P(r ) [/tex]
[tex]P(\= r ) = 1 -0.30 [/tex]
[tex]P(\= r ) = 0.70 [/tex]
The probability that the bus run late if it rains is [tex]P(L | r) = 0.4[/tex]
The probability that the bus run late if it does not rain is [tex]P(L | \= r) = 0.15[/tex]
Generally the probability that it will rain and the bus will be late is mathematically represented as
[tex]P(r n L) = P(L | r) * P(r)[/tex]
=> [tex]P(r n L) = 0.4 * 0.30[/tex]
=> [tex]P(r n L) = 0.12[/tex]
Generally the probability that the bus will be late is mathematically represented as
[tex]P(L) = P(r) * P(L|r) + P(L | \= r) * P(\= r)[/tex]
=> [tex]P(L) = 0.30 * 0.4 +0.15*0.70[/tex]
=> [tex]P(L) = 0.225[/tex]
Generally given that the bus ran late, the probability that the bus it was not raining is mathematically represented as
[tex]P(\= r | L) = 1- P(r | L )[/tex]
Here [tex]P(r | L ) = \frac{P(r n L)}{P(L)}[/tex]
=> [tex]P(r | L ) = \frac{0.12}{0.225}[/tex]
=> [tex]P(r | L ) = 0.533 [/tex]
So
[tex]P(\= r | L) = 1- 0.533[/tex]
=> [tex]P(\= r | L) = 0.467 [/tex]
200 bottles of equal capacity hold 350 liters of water .How much does each hold?
Answer:
SECRET HAHAHAHHA
Step-by-step explanation:
Answer:
1.75 liters
Step-by-step explanation:
We know that all 200 bottles can hold 350 liters of water.
Suppose each bottle holds b liters of water. Then we can model the situation in terms of b:
200b = 350
Divide both sides by 200:
b = 350/200 = 35/20 = 1.75
The answer is thus 1.75 liters.

Write the three forms of the line parallel to the line represented by the equation, 8x+3y=11 such that it passes through the point (9, -5).
Answer:
8x + 3y = 57y = -8/3x + 19y + 5 = -8/3(x - 9)Step-by-step explanation:
Given function
8x+3y=11Line parallel to the given has the same slope and passes through the point
(9, -5)Determining the equation
8x + 3y = c8*9 + 3*(-5) = cc=72 - 15c = 57So the function is in standard form
8x + 3y = 57Converting to slope-intercept form
y = mx + b3y = -8x + 57y = -8/3x + 573y = -8/3x + 19Point-slope form, using the given point
y - y1 = m(x - x1)y - (-5) = -8/3(x - 9)y + 5 = -8/3(x - 9)its proportions I'm In number 2

Frank rented a truck for one day. There was a base fee of $16.99, and there was an additional charge of 76 cents for each mile driven Frank had to pay
$228.27 when he returned the truck. For how many miles did he drive the truck?
miles
Answer:
267
Step-by-step explanation:
Answer: He drove the truck for 278 miles.
Step-by-step explanation:
We can represent the situation by the equation, 16.99 + 0.76x = 228.27 where x is the number of miles. 16.99 is the base fee an 0.76 is the same as 76 cents .
Solve for x in the equation to find out how many miles was driven.
16.99 + 0.76x = 228.27
-16.99 -16.99
0.76x = 211.28
x= 278

a 2-lb bag for $5.39
a 5-lb bag for $12.99
Which size bag is the best price per pound?
Answer: 5-lb bag for $12.99
Step-by-step explanation: I multiplied 2 x 2.5 and 5.39 x 2.5. It was more than $12.99. This means that the 5 pound bag is less expensive.
Two goals post are 8m apart. A footballer is 34m from one and 38m from the other. Within what angle must he kick the ball if he is to score a goal?
Answer:
11.06°
Step-by-step explanation:
The law of cosines can be used to find the angle. The sides adjacent to that angle are a=34, b=38, and the side opposite is c=8. Then the angle is found from ...
c² = a² +b² -2ab·cos(C)
cos(C) = (a² +b² -c²)/(2ab)
C = arccos((a² +b² -c²)/(2ab))
C = arccos((34² +38² -8²)/(2·34·38)) = arccos(317/323)
C ≈ 11.06°
From the footballer's viewpoint, the goal posts are 11.06° apart.

Step-by-step explanation:
A motorcyclist is riding along a mountain trail that runs parallel to a road below. In fact the trail is 6 meters above the road. The motorcyclist then notices a flat bed truck directly below moving at the same speed and decides to drive off the trail, without changing speed. Fortunately, the motorcycle safely lands on the flatbed of the truck. What would the outcome have been if the trail was 12 meters above the road, but all other parameters remain the same?
Answer:
The motorcycle would still land on the truck FLATBED just the way it landed when the trail was 6 meters above the road.
Step-by-step explanation:
Based on the information given about the motorcyclist we were told that the trail was 6 meters above the road in which despite that the motorcyclist drive off the trail without changing his motorcycle speed which made the motorcycle to land on the truck FLATBED which means that if the trail was 12 meters above the road while all other parameters remain the same what the outcome could have been is that the motorcycle would still land on the truck FLATBED just the way it safely landed when the trail was 6 meters above the road.
Therefore FLATBED truck can simply be defined as truck which does not have any thing covering both the right side and left side of truck and as well does not have roof making the truck to have a FLATBED or flatbody which is why most of this type of truck are mostly used to transport goods or loads that are heavy.

184.36
9,027.83
Which number has the smaller value of the 8? How many times
smaller is it?
Answer:
9,027.83
100 times smaller
Step-by-step explanation:
Given 184.36, the place value of 8 in the number is 8 tens i.e 8* 10 = 80
The place value of 8 in 9,027.83 is 8 tenth i.e 8* 1/10
8* 1/10 = 8/10
8/10 = 0.8
Hence the number that has the smaller value of 8 is 9,027.83.
To get how many times smaller the number is, we will take the ratio of 80 to 0.8 as shown:
[tex]= \frac{80}{0.8}\\ \\= 80 \div 0.8\\\\= 80 \div \frac{8}{10} \\\\[/tex]
[tex]= 80 * \frac{10}{8}\\ \\= \frac{800}{8}\\ \\= 100[/tex]
This means that the number 0.8 is 100 times smaller than 80
