Assume that the random variable x is normally distributed, with mean ? = 50 and standard deviation ? = 7. compute the following probabilities. be sure to draw a normal curve with the area corresponding to the probability shaded. p(56 < x < 68)

don't know what that says sorry i can't you

step-by-step explanation:

idk what it says

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

happy to

pls mark as brainliest

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
