Answer:
The best estimate is 32 out of 32 times, she will be early to class
Step-by-step explanation:
The probability of being early is 99% = 99/100 = 0.99
So out of 32 classes, the best estimate for the number of times she will be early to class will be;
0.99 * 32 = 31.68
To the nearest integer = 32

The answer is b. Because you x can be a negative, but you’re squaring it so it will equal a positive, and if you add 4, it is still 4 or greater

Answer:
   -2/3
Step-by-step explanation:
The slope formula is useful for this.
   m = (y2 -y1)/(x2 -x1)
   m = (2 -(-6))/(-9 -3) = 8/-12
   m = -2/3
The slope of the line is -2/3.
