Suppose x has a distribution with µ = 18 and σ = 12. A button hyperlink to the SALT program that reads: Use SALT. (a) If a random sample of size n = 32 is drawn, find µx, σ x and P(18 ≤ x ≤ 20). (Round σx to two decimal places and the probability to four decimal places.)

i dont know sorry

step-by-step explanation:

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

answer: dead jah

step-by-step explanation:

bullet + jah= dead jah

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
