Having done poorly on their math final exams in​ June, six students repeat the course in summer​ school, then take another exam in August. If we consider these students representative of all students who might attend this summer school in other​ years. Do these results provide evidence that the program is worthwhile? June 54, 49, 68, 66, 62, 62

August 50, 65, 74, 64, 68, 72

Required:

Evaluate on a TI 83 calculator

step-by-step explanation:

don't report but were is the digram

step-by-step explanation:

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5

large crystals result from very slow cooling.

evaporation of water: this would produce an evaporite which is a sedimentary rock. like a salt pan in a desert. not possible to have volcanic rocks originate this way.

crystalization in molten earth: slow cooling over time. (hundreds to millions of years)

crystalization at earth's surface: this results in fast cooling. (a few hours to a few months or years)

crystalization from cooling off hot water: that would be a hydrothermal deposit. while associated with volcanics they are not volcanic rocks themselves and usually occur fairly rapidly.
