Suppose the sediment density (g/cm) of a randomly selected specimen from a certain region is normally distributed with mean 2.61 and standard deviation 0.91. A button hyperlink to the SALT program that reads: Use SALT. (a) If a random sample of 25 specimens is selected, what is the probability that the sample average sediment density is at most 3.00

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

b

step-by-step explanation:

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

where does the z at is it on the x axes or on the y axes any way if it is on the y axes put it horizontally and if it is on the x axes put it vertically
