The work of a student to solve a set of equations is shown
Equation A y = 15 - 22
Equation B: 3y = 3 - 42
Step 1: -3y) = -3(15 -22) (Equation A is multiplied by-3.]
3y = 3-4 Equation B]
Step 2: -3y = 15-22 (Equation A in Step 1 is simplified)
3y = 3 - 42 [Equation B]
Step 3: 0= 18-62 Equations in Step 2 are added]
Step 4: 62 = 18
Step 5: Z=3
In which step did the student first make an error?
Step 4
Step 3
Step 2
Step 1

What’s the range cuz i can’t find it?

Need to finish my juan wants to build a greenhouse in his back yard. he needs to maximize the ratio of floor area to structure volume in order to provide the most room for plants while minimizing the area to be heated. find the description of the structure that best meets juan’s criteria. a.) a hemisphere with a diameter of 12 feet b.) a cube with a side length of 12 feet c.) a cone with a diameter of 12 feet and a height of 10 feet d.) a square pyramid with a base side length of 12 feet and a height of 9 feet

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.
