A. If the price of the bathing soap is reduced by $0.50, what is the expected increase in sales per store? Additionally, provide a 95% confidence interval for the expected increase. b. The product manager claims that if the price is reduced by $0.50, average sales will increase by at least $160 per store. Do the data allow you to reject this claim at a level of significance of 5 percent?

answer: ouch. thats difficult

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

d is ur answer hopes this i dont really know how to explain it to u.
