Answer:
0.4
Step-by-step explanation:
The table with correct formatting is attached in the image below.
We have to find P(Y | B). This is a conditional probability i.e. probability of Y given B.
The formula of conditional probability for two event A and B is:
So, for the given case, the formula would be:
P(Y ∩ B) indicates the probability of Y and B occurring together. Y and B occur together 34 times out of total of 324, so:
P(B) indicates the probability of occurrence of B. B occurs 85 times in a total of 324. So,
Using these values in the formula of conditional probability, we get:
Thus, the value of P(Y|B) is 0.4
Answer:
2.4 hours
Step-by-step explanation:
note
speed= distance/time
Step one:
given data
Tim takes 3 hours to reach his destination traveling at a constant speed of 12 miles per hour.
time= 3 hours
speed= 12mph
distance covered= speed*time
distance covered= 12*3
distance covered= 36 miles
Step two:
The distance remains the same
if time drives at 15mph
we are expected to find the time Tim took
time= distance/velocity
time= 36/15
time= 2.4 hours
<h3>
Answer: 110 degrees</h3>
======================================================
Work Shown:
x = measure of minor arc CL
angle J = ( (far arc) - (near arc) )/2
angle J = ((red arc) - (yellow arc))/2
angle J = ( (minor arc CL) - (minor arc CK) )/2
35 = ( x - 40 )/2
35*2 = x-40
70 = x-40
x-40 = 70
x = 70+40
x = 110
Minor arc CL = 110 degrees
Well
3x^2+6x-x-2
So the answer would be
3x^2+5x-2
Answer:
Option B. 93.46 ft³
Step-by-step explanation:
In the given question tow solids are given.
Their heights are same and the cross sectional areas at every level parallel to the respective bases are same which means total volume of solids are also same.
We have to find the volume of the cone.
We know the formula of volume of a pyramid 
Now area of the base = area of a right angle triangle = 
Here height of the right angle triangle = 8 ft
and base of the triangle = 
Now area of base = 
Now volume of cone = volume of pyramid = 
Therefore Option B. is the answer.
