Answer:
who knows what your saying
Find out the value of z
Remember that
z =(x - μ)/σ
we have
μ=18
σ=5
For x=5
substitute
z=(5-18)/5
z=-2.6
Using a z-scores table
we have that
P(x ≥ 5)=0.99534
therefore
<h2>the answer is option A</h2>
Answer:
Step-by-step explanation:
This is the Law of Cosines. Use the following formula:
and simplify to
26.01 = 10.89 + 10.89 - 21.78cos(x) and a bit more to
4.23 = -21.78cos(x) and finally to
-.194214876 = cos(x) and use the 2nd button along with the cos button to find that the missing angle is 101.2 degrees
