  (1) logb(d/a) +c

Step-by-step explanation:

As with any "solve for ..." problem, it is useful to consider the operations performed on the variable. The Order of Operations helps you here.

For this equation, we have ...

The way to proceed is to "undo" these operations, starting from the last one and working up the list.

We undo multiplication using division. Here, we need to divide by a.

We can unto the raising to a power by using logarithms. Here, it is convenient to use base-b logarithms.

Finally, we undo the subtraction of c by adding it to the equation.

_____

The applicable rule is that these two expressions are equivalent:

hi there!

the answer will be d: 2

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
