Emma's grades are 100, 98, 94, 90, and 88. Emma decides not to study for the final because her grades are so high on all of the previous tests. Emma scores 64 on the final. As an outlier, how does 64 affect the mean of Emma's previous scores? Assume all scores are treated equally.

Averagex =89

Sizen =6

SumSum =534

Solution:

The Average (Mean) is equal to the Sum of all data divided by the Size of the data set.

Average = Sum / Size

= 534 / 6

= 89

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
