What is the solution to -4|-2x+6| = -24

1 answer:

7 0

X = 0. Since the absolute value of -2x+6 is 2x+6, the absolute value sign acts as () so it would be -4(2x+6) = -24. That would come out to be -8x -24 = -24. Using proper algebra, the answer would come out to be 0

Conditional Probability

trapecia [35]

To solve for P(QIR) we use the formula:
P(QIR)=[P(Q∩R)]/P(R)
But from the diagram:
P(Q∩R)=3/22
P(R)=7/22
hence
P(QIR)=3/22÷7/22=3/7

Of the 200 students surveyed at the local high school, 126 say that they prefer earlier start times for school. What is the mean

ra1l [238]

Answer:

The mean of sampling distribution of the proportion of the students who prefer later start times for school

μₓ = p = 0.63

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given sample size 'n' =200

given data Of the 200 students surveyed at the local high school, 126 say that they prefer earlier start times for school

sample proportion

$p = \frac{x}{n} = \frac{126}{200} = 0.63$

The mean of sampling distribution of the proportion of the students who prefer later start times for school

μₓ = p = 0.63

Standard deviation of the proportion

$S.D = \sqrt{\frac{p(1-p)}{n} } = \sqrt{\frac{0.63(1-0.63)}{200} } = 0.034$
