The correct answer for the question that is being presented above is this one: "B. 68%." The weights of a bat in a zoo are normally distributed with a mean of 2.2 pounds and a standard deviation of 0.3 pounds. The percent of the bats at the zoo that weigh 1.9 pound and 2.5 pounds is <span>B. 68%</span>

foot
Step-by-step explanation:
If your teacher do not put the value of the q all the letters will be 1 so: 1+5=6 (after you just simplify)
Answer:
I think question is:
(x+4x+2)(2x^2+3x-4)
:(5x+2)(2x^2+3x-4)
5x(2x^2+3x-4)+2(2x^2+3x-4)
10x^3+15x^2-20x+4x^2+6x-8
10x^3+19x^2-14x-8
He made a mistake in step #2. It seemed to be a trivial mistake because it involved signs, but it still had a great impact. Since step#2, his solution was already wrong.
Instead of
(-1)²-4(2)(-6) = 1 + 48 = 49
What he did is
(-1)²-4(2)(-6) = -1 + 48 = 47
