Answer:
30.0
Step-by-step explanation:
Given our data is normally distribute with and
-Top 7% is given by find the z-value corresponding to p=(1-0.07)=0.93
-We substitute our values in the equation below;
Hence, the minimum score required for the scholarship is 30.0
Question 1.
The Pythagoras Theorem states that the square of the hypotenuse is equal to the sum of the square of the two legs.
From the question, the hypotenuse is h=10 yd and one of the legs is 2yd.
This implies that,
Evaluate the exponents
Subbtract 4 from each side
The correct answer is C
Question 2
We want to solve
using inverse functions.
The inverse of an exponential function is a logarithmic function.
We take natural log of both sides to get;
Recall that
This means
Logarithm of the base is 1
Divide both sides by 4
