Basically we have to calculate P X < 0.95. By using the normal distribution formula for any random variable we can get our answer.
SO first from z table we will have to check the corresponding z value from the table. After we get that value we can do X - mean / the std dev = that particular value that i am naming A.
SO X - 5 / 0.5 = A. Now we can solve X for our answer.
Answer:
h=V πr2
Step-by-step explanation:
1: Find the volume of the cylinder. Volume: 120 = h=V πr2
2: Since there is no radius the answer will be that and we also finding the for the cone.
3: Volume of the cone will be h=V πr2 since we finding for the volume for both.
Hope this helps.
Answer:
k = -5
Step-by-step explanation:
y = -8x - 73 and x = -4
y = (-8) (-4) - 73 = - 41 : intersect at (-4 , - 41)
(-4 , - 41) must at y = 9x + k
-41 = 9*(-4) +k
k = -41 + 36 = -5
y = 9x - 5 x<-4
Karen is moving at 81.2 miles per hour while Melinda is moving at 71.2 miles per hour.
<h3>Equation for
speed</h3>
Speed is the ratio of total distance travelled to total time taken. It is given by:
Speed = distance / time
Let a represent Karen speed and b represent Melinda speed, hence:
a = b + 10
a - b = 10 (1)
Also:
a = d₁ / 1
d₁ = a
b = d₂/ 1 hour
d₂ = b
Since they are 108 miles apart, using Pythagoras:
108² = d₁² + d₂²
a² + b² = 11664
(b + 10)² + b² = 11664
b = 71.2 mph, a = 81.2 mph
Karen is moving at 81.2 miles per hour while Melinda is moving at 71.2 miles per hour.

Step-by-step explanation:
first get the 34 hour of dogeball and get the 14 hour of basketball subtract 34 - 14 first 4 - 4 = 0 then 30 - 10 = 20
