Answer:
0.8041
Step-by-step explanation:
We know that
μ=72 and σ=5
and P(65<X<78)
We can determine the Z value as (X-μ)/σ
P( 65<X<78 )=P( 65-72< X-μ<78-72)
To fine the Z values:
From the standard normal tables:
to find P ( Z<-1.4)
From the standard normal tables:
Therefore
Answer:
Step-by-step explanation:
Here, the given expression is:
Now, by logarithm rules, we know
if
, then x =
Comparing here, b = 10 and z = 2
⇒ y =
or,
