Answer:
51 = 1 x 51 or 3 x 17. Factors of 51: 1, 3, 17, 51.
Answer:
The first one and the last one. A and D.
Step-by-step explanation:
A linear equation is and equation where the line is going up on a graph. In order for that to happen, y must always be bigger than x. The first and last chart all the way to the right is the only one that has that trait. :)
For
y=ax²+bx+c
the x value of the axis of symmetry is -b/(2a)
so test them
A., -b/(2a)=-(-8)/(2*-2)=8/-4=-2, yep
B. -b/(2a)=-2/(2*1/2)=-2/1=-2, yep
C. -b/(2a)=-(-16)/(2*4)=16/8=2, nope, need -2
D. -b/(2a)=-12/(2*3)=-12/6=-2, yep
answer is C
Answer: 0.9738
Step-by-step explanation:
We assume that the scores follows a normal distribution.
Let denotes the class average .
As per given we have,
Sample size : n= 12
The probability that a class of 15 students will have a class average greater than 70 on Professor Elderman’s final exam will be :
Hence, the correct answer = 0.9738
