1. If Russell takes a 25 question multiple choice test and receives a score of 56%, how many questions did he answer correctly? 2. If his teacher used a 95% confidence interval to correctly estimate the true percentage of correct answers that he should have scored on this exam, what possible grades could the teacher reasonably assign to Russell?

3. However, because Russell's teacher must pick only one number to represent his grade, what percentage will the teacher typically assign as the grade?

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

where's the diagram?

step-by-step explanation:

“a term can be a signed number, a variable, or a constant multiplied by a + sign or j sign. in , the terms are 5x , 3y and 8. when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.” i hope this you.
