Professor ivy collects data on the time it takes for ivy tech students to travel to school. she find that she can model the data with the normal distribution. the mean commute time is 27.5 minutes with a standard deviation of 5.2 minutes. what is the interval of commute times for the middle 68% of students?

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.

step-by-step explanation:

the diver is 33 feet below the surface.

step-by-step explanation:

hope this

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).

answer is c.

quadrilateral

hope you got it chief
