Answer:
Jodi must score at least 8.8 points.
Step-by-step explanation:
Step 1: Given data
Score 1 (S1): 8.9
Score 2 (S2): 7.1
Score 3 (S3): 9.2
Average (Av): 8.5
Score 4 (S4): ?
Step 2: Calculate the Score 4 so that the average is 8.5
The average is equal to the sum of the scores divided by the number of scores (4).
Av = (S1 + S2 + S3 + S4)/4
4 × Av = S1 + S2 + S3 + S4
S4 = 4 × Av - S1 - S2 - S3
S4 = 4 × 8.5 - 8.9 - 7.1 - 9.2
S4 = 8.8
Jodi must score at least 8.8 points.
For the exponential problem, what is true about that problem is the answer B and D
Answer:
7.6(<em>a</em>+<em>b</em>) A.
8.205-2<em>d</em> D.
9. 0.05<em>n</em>+0.10<em>d</em>+0.25<em>q</em>=10 B.
Answer:
TS = 22
x = 49
Step-by-step explanation:
(5x-2)/39 = (3x+1)/26
Multiply both sides by 78:
10x-4 = 9x+3
x=7
3x+1 = 22
:::::
(x+5)/36 = 30/20
x+5 = 54
x = 49
Answer:
69
