Your final grade in math class is calculated by adding 75% of your semester average to 25% of your final exam grade. if your semester average is 88, what grade must you get on the final exam in order to get an a- for your final grade? (note: an a- is for a final grade of 90-92) show work.

If u get a 96 on the exam u would get a 89.6% average which would round up but if u don’t do rounding then u would have to get a 98 to get exactly a 90% average.

a. the residual plot for model 1 has a random pattern and is a good fit for the data.

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
