Answer:
Tanner's score = 70
Step-by-step explanation:
Data provided in the question:
Mean value of the statistics test taken by Tanner = 80
Standard deviation = 5
Total points possible = 100
Now,
It is given that the Tanner's score was 2 standard deviation below the mean
Mathematically,
Tanner's score = Mean - ( 2 × Standard deviation )
or
Tanner's score = 80 - ( 2 × 5 )
or
Tanner's score = 80 - 10
or
Tanner's score = 70
2x-3/4=1/2
The answer is X=5/8
I hope this helps you
7.log2 (x)=15.log2 (2)
log2 (x)^7=log2 (2)^15
x^7=2^15
(x^7)^1/7=(2^15)^1/7
x=2^15/7
