Answer:
D
Step-by-step explanation:
x^2+2x-5-(-3x^2-4x+1)
x^2+2x-5+3x^2+4x-1
4x^2+6x-6
Volume of prism B=800*6³/8³
=800*27/64
=25*27/2
=575/2
=287.5 cm³
Given that the sample size is 12, thus the degree of freedom = 12 - 1 = 11.
Using technology, the p value of the t statistic, t = 2.028 is 0.9663.
total mass = mass of a bag of candy + mass of a chocolate bar
total mass = 80g +110g = 190g
22/25 is 88/100 in simplest form
