To evaluate the probability that the lifespan will be between 1440 and 1465 hours will be given by:
P(1440<x<1465)
using the z-score formula we obtain:
z=(x-μ)/σ
where:
μ=1450
σ=8.5
hence
when x=1440
z=(1440-1450)/8.5
z=-1.18
P(z<-1.18)=0.1190
when x=1465
z=(1465-1450)/8.5
z=1.77
P(z<1.77)=0.9625
hence:
P(1440<x<1465)
=0.9625-0.1180
=0.8445

They are the only alternate exterior angles
Answer:
The volume of a cylinder:
Step-by-step explanation:
-To find the volume of a cylinder, you first need the formula:
diameter
height
-Use the following diameter and height for the formula:
-Then, you solve:
-Since the hundredth place is 2, It cannot be rounded to the nearest hundredths place, so it would be:
A major arc is over 180°.. minor arcs are under 180°... I think this is right
Hope this helps
Answer:
True
Step-by-step explanation:
We know that The triangle inequality states that the sum of the two sides of the triangle is always greater than the third side.
Here given that two sides of the triangle are 7 and 10
Let the third side be x
Here a = 7 , b = 10 , c = x
According to the triangle inequality
a + b > c
7 + 10 > x
x < 17
Also c + b > a
x + 10 > 7
x > -3
Also a + c > b
7 + x > 10
x > 3
Combining all the above results we get
3 < x < 17
All the values of x in the above region forms a triangle
Given x values lies in the region so they form a triangle
