I am thinking you mean 93 to represent William's scores of 91, 92, and "q3"on three quizzes in Queston 8a
Answer:Average (x)= 92
b.William needs 97 as his third score to get as average of 90
Step-by-step explanation:
a.
The Average ( x) of the scores can solved using the Formulae
Average ( x)= Sum of scores / Number of Scores
Average ( x) = (Score 1 + Score 2 + Score 3) /3
Average (x)= (91, 92, and 93 )/3=276/3 = 92
b) Average ( x) of the scores = Sum of scores/ Number of Scores
Now let Score be represented as S such that
Average (x) = (S 1 + S 2 + S3 )/ 3
90 = 85+ 88+ S/ 3
90 x 3= 85+ 88 + S
270=173+ S
S= 270- 173
S=97
William needs 97 as his third score to get as average of 90
I think 47.1 I followed the formula.
Answer:
a+ 96
Step-by-step explanation:
A= (1/2*18 + 1/2*6) *8
A= (9 + 3) * 8
A= 12 * 8
A= 96
Answer:
Step-by-step explanation:
a^2 +b^2 =c^2 Use pythagorean theorem
8^2 +b^2 =9^2 Substitute in your known values
b=
b=
A triangle leg cannot be a negative length
Find cosine of angle theta.
Answer:
Slope of Function B = 2 x Slope of Function A.
Step-by-step explanation:
The graph of Function B shows its slope to be 4 units up for 1 unit to the right, so 4.
The equation for Function A shows its slope to be the coefficient of x, so 2.
___
4 is 2 times 2, so ...
the slope of Function B is 2 times the slope of Function A.
