ANSWER
EXPLANATION
The outermost square tile has side length,
The area of a square is given by;
We substitite the given expression for the side length into the formula to obtain,
We expand using the distributive property to obtain;
This gives us:
The last choice is correct.
Answer:
Step-by-step explanation:
Since the amplitude of the cosine function is 2, I would put the multiply it by 2. There is no phase shift
The period is 1/2, so it would be 4pi
Plug them in into y=Acos(Bx), y=2cos(4pix)
Answer: 0.0023
Step-by-step explanation:
Let X be the binomial variable that represents the number of receipts will show that the above three food items were ordered.
probability of success p = 32% = 0.32
Sample size : n= 10
Binomial probability function :
Now, the probability that eight receipts will show that the above three food items were ordered :
hence, the required probability = 0.0023
Option C: is the slope of the line
Explanation:
The line passes through the points and
We need to find the slope of the line.
The slope can be determined using the formula,
Where the coordinates and
are
and
Let us substitute the points in the formula
Thus, we have,
Simplifying, we get,
Adding the numerator and denominator, we have,
Cancelling the negative terms, we get,
Thus, the slope of the line is
Therefore, Option C is the correct answer.
