Divide by 2 to get
5^x = 7
Now take the logarithm.
x·log(5) = log(7)
x = log(7)/log(5) ≈ 1.209062
Answer:

Answer:
The answer is B.
Step-by-step explanation:
The answer's B because If you look at the box and whisker plot the median is 6. That is true because 5 + 7 = 12 and divided by 2 would equal 6 therefore the median is 6. Also the 1st oulier is 1 and the 2nd outlier is 11. There you go hope you understand it.....
Area of a trapezoid = ((a+b)/2) * h
a = x + x
b = z + z
h = y
A = ((4 + 12)/2) * 6
A = ((16)/2) *6
A = 8 * 6
A = 48
answer is B
