1/2 (2y-6) = 24 1/4 (4-y) = 10 + 24

2 (2y-3) = 4y-6

1/3 (6y-9) = 24 - 3

I think they’re linear equations but I don’t know what to do. The directions say to solve if possible??

The annual snowfall in a town has a mean of 38 inches and a standard deviation of 10 inches. last year there were 63 inches of snow. find the number of standard deviations from the mean that is, rounded to two decimal places. 0.44 standard deviations below the mean 2.50 standard deviations below the mean 0.44 standard deviations above the mean 2.50 standard deviations above the mean

Solve each quadratic equation by factoring and using the zero product property. x^2 - 8x + 30 = 3x

Ahypothesis is: a the average squared deviations about the mean of a distribution of values b) an empirically testable statement that is an unproven supposition developed in order to explain phenomena a statement that asserts the status quo; that is, any change from what has been c) thought to be true is due to random sampling order da statement that is the opposite of the null hypothesis e) the error made by rejecting the null hypothesis when it is true
