The weights of a dog show is normally distributed with a mean of 58 pounds and a standard deviation of 17.2 pounds. Use the standard normal curve to find each of the following probabilities. *Notice if it says z (indicating z-score) or x (indicating data value).

**Remember with percentages to use percent symbols, but probabilities must be less than 1. So probabilities DO NOT have percent symbols. Round to the nearest ten-thousandth.

step-by-step explanation:

infinity is the answer

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.

you'll have to attache the image of the bar graph in order for us to answer : )
