Answer: 28</h3>
Explanation:
90° is 90/360 = 1/4 of a full 360° rotation. Meaning that if the central angle of the pizza slice is 90°, then we have four equal slices.
One slice is 7 square inches, so all four slices combine to 7*4 = 28 square inches
Answer is C
The conjugate of the complex number a+bi is a-bi
you just reverse the sign of the imaginary part of the number ; so it is 4-51i
Answer: Our required probability is 0.044.
Step-by-step explanation:
Since we have given that
Number of customers who have entered the drawing = 17
Number of customers live in the town of Gaston = 5
Number of customers live in Pike = 4
Number of customers live in Wells = 8
The first customer will be selected and then second customer will be selected from the remaining .
Probability of getting first customers are Pike residents = 
Probability of getting second customers are Pike residents = 
So, the probability that both customers selected are Pike residents are
Hence, our required probability is 0.044.

Answer: 7/26
Step-by-step explanation:
Number of purple marbles = 6
Number of white marbles = 7
Total number of marbles = 13
The probability of first drawing a white marble will be = 7/13
The probability of drawing a purple marble the second time will be = 6/12 = 1/2
The probability that the first marble is white and the second one is purple will now be:
= 7/13 × 1/2
= 7/26
Note that since there are 13 marbles, when the first purple marble is drawn, there'll be 12 marbles left.
