12x^2-4
Step-by-step explanation:
Answer: Type I error would be a conclusion that average time spent on phone by teenager is higher than 4.5 hours per week which is actually the same.
Step-by-step explanation:
Type 1 error occurs when a null hypothesis is true but researcher rejects it.
Let 
be the average time spent on the phone by teenagers .
Here, Null hypothesis: 
Alternative hypothesis : 
So, Type I error would be a conclusion that average time spent on phone by teenager is higher than 4.5 hours per week which is actually the same.
Answer:
x = 3 1/2
Step-by-step explanation:
You could simplify the given equation first, then solve the resulting 2-step linear equation. It might work better to undo the operations done to the variable.
<h3>Solution</h3>
(5 1/6 -x)(2.7) -5 3/4 = -1 1/4 . . . . . given
(5 1/6) -x)(2.7) = 4 1/2 . . . . . . . add 5 3/4 to both sides
(5 1/6 -x) = 4.5/2.7 = 5/3 . . . divide by 2.7
31/6 -10/6 = x . . . . . . . . . . add x-5/3, use common denominators
21/6 = x = 7/2
x = 3 1/2
Answer:
When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles. Example: a and e are corresponding angles. When the two lines are parallel Corresponding Angles are equal.
