A student ran out of time on a multiple choice exam and randomly guessed the answers for 2 problems. Each problem had 5 answer c

frozen [14]

So if there are 5 choices and only one is correct, there is a 1/5 chance of being correct. since there was 2 questions, you need to multiply 1/5 by 1/5 to get 2/25 of getting both questions correct.

i hope this helps!!

What is the value of y if log <base 5> <index -7> = y?

Dvinal [7]

Answer:

Hence, the value of y is undefined.

Step-by-step explanation

$log_{5} (-7) = \frac{log(-7)}{log(5)}$ from the property, log_a (b) = (log(a))/log(b).

The value log (-7) was not defined. So, the entire log value also not defined.

Hence, the value of y is undefined.

Which system of inequalities has a solution set that is a line?

Korolek [52]

We're going to solve each of the systems to determine the solution.

System $1$

$x+y \geq 3\\ x+y \leq 3$

using a graph tool

the solution is the line $x+y=3$

see the attached figure N $1$

System $2$

$x+y \geq -3\\ x+y \leq 3$

using a graph tool

the solution is the shaded area

see the attached figure N $2$

System $3$

$x+y > 3\\ x+y < 3$

using a graph tool

The system has no solution

see the attached figure N $3$

System $4$

$x+y > -3\\ x+y < 3$

using a graph tool

the solution is the shaded area

see the attached figure N $4$

therefore

the answer is

System $1$ 

$x+y \geq 3\\ x+y \leq 3$
