A student takes a 21- question, multiple-choice exam with four choices for each question and guesses on each question. Assume the variable is binomial.

Find the probability of guessing at least 10 out of 21 correctly.

333.74 ! should be your answer for this question

simplifying

7ln(x + 2.8) = 11.2

reorder the terms:

7ln(2.8 + x) = 11.2

(2.8 * 7ln + x * 7ln) = 11.2

(19.6ln + 7lnx) = 11.2

solving

19.6ln + 7lnx = 11.2

solving for variable 'l'.

move all terms containing l to the left, all other terms to the right.

reorder the terms:

-11.2 + 19.6ln + 7lnx = 11.2 + -11.2

combine like terms: 11.2 + -11.2 = 0.0

-11.2 + 19.6ln + 7lnx = 0.0

the solution to this equation could not be determined.

step-by-step explanation:

i searched it on google but it says that the solution to this equation could not be determined but i hope that it you a little.

you must evaluate the function f first.   division by 0 is undefined. therefore, the composition cannot be evaluated.
