Answer:
The area (probability) is: 0.6864.
Step-by-step explanation:
According to the statement, we are in front of a normal distribution with the following parameters:
µ (mean) = 0
σ (Standard deviation) = 1.
Then we need to find the area of the shaded region, which is the area between the points -1.21 < z < 0.84.
And the area (probability) is: 0.6864.
Step-by-step explanation:
using trig, tangent is equal to opposite over adjacent.
in this case, the angle is 45, opposite is 7, and adjacent is a.
thus tan 45° = 7/a
solve for a to get a = 7/tan 45° = 4.32
To simplify 14^(5x+2)<11(4x-1)
x < -2.130032
An=a1+d(n-1)
a1=first term
an=nth term
d=common dffernce
given
first term is -5
it increases by 1
an=-5+1(n-1)
a10
a10=-5+1(10-1)
a10=-5+1(9)
a10=-5+9
a10=4
10th term or a10 is 4
