Hedly gathered the following evidence. 5(22) = 110 5(33) = 165 5(44) = 220 Which conjecture might Hedly make from this evidence? Is the conjecture valid? Select one: a. When you multiply 11 by a multiple of 5, the first and last digits of the product will sum to the middle digit; this conjecture is valid.

b. When you multiply 11 by a multiple of 11, the first and last digits of the product will sum to the middle digit; this conjecture is valid.

c. When you multiply 5 by a multiple of 11, the first and last digits of the product will sum to the middle digit; this conjecture is valid.

d. When you multiply 5 by a multiple of 11, the first and last digits of the product will sum to the middle digit; this conjecture is not valid.

Aye asap pls ! markin da brainiest too ! btw da step choices are all add, distribute, divide, n subtract

Andy has $310 in his account. each week, w, he withdraws $30 for his expenses. which expression could be used if he wanted to find out how much money he had left after 8 weeks?

The resumâ´es of two male applicants for a college teaching position in chemistry are placed in the same file as the resumâ´es of two female applicants. two positions become available, and the first, at the rank of assistant professor, is filled by selecting one of the four applicants at random. the second position, at the rank of instructor, is then filled by selecting at random one of the remaining three applicants. using the notation m2f1, for example, to denote the simple event that the first position is filled by the second male applicant and the second position is then filled by the first female applicant, (a) list the elements of a sample space s; (b) list the elements of s corresponding to event a that the position of assistant professor is filled by a male applicant; (c) list the elements of s corresponding to event b that exactly one of the two positions is filled by a male applicant; (d) list the elements of s corresponding to event c that neither position is filled by a male applicant; (e) list the elements of s corresponding to the event a â© b; (f) list the elements of s corresponding to the event a âş c; (g) construct a venn diagram to illustrate the intersections and unions of the events a, b, and c.
