Answer:
115*
Step-by-step explanation:
Because the angles are interior angles they are going to be equal to 180. So 180-65=115
When change in one variable is accompanied by the change of another variable in the same direction, they are directly proportional to each other, and it is usually represented by the general equation, y = kx where k is a constant.
Answer:
k(3n) = 9n² + 9n
General Formulas and Concepts:
Order of Operations: BPEMDAS
- Substitution and evaluation
Step-by-step explanation:
<u>Step 1: Define</u>
k(n) = n² + 3n
k(3n) is n = 3n
<u>Step 2: Solve</u>
- Substitute: k(3n) = (3n)² + 3(3n)
- Exponents: k(3n) = 9n² + 3(3n)
- Multiply: k(3n) = 9n² + 9n
Answer:
The probability is 0.933
Step-by-step explanation:
We start by calculating the z-score
Mathematically;
z-score = (x-mean)/SD
x = 4
mean = 5.5
SD = 1
z-score = (4-5.5)/1 = -1.5
So we proceed to get the probability
This is;
P( z > -1.5)
we can get this from the standard normal distribution table
That will be
P(z > -1.5) = 0.93319
To the nearest thousandth, this is 0.933
