Answer:
Regression to the mean fallacy
Step-by-step explanation:
It assumes that something has returned to normal because of corrective actions taken while it was abnormal. This fails to account for natural fluctuations. It is frequently a special kind of the post hoc fallacy.
Simplify whatever is in the parenthesis:
(5×^2-4x-1) and <span>(4x^2-4)
after that subtract the numbers you got from both </span>parenthesis after simplifying
Answer: An adult ticket cost $12
A child ticket cost $5
Step-by-step explanation:
Let x represent the price for one adult ticket.
Let y represent the price for one child ticket.
A movie theater sold 4 adult tickets and 7 children's tickets for $83 on Friday. It means that
4x + 7y = 83 - - - - - - - - - - - -1
The next day the theater sold 5 adult tickets and 6 children tickets for $90. It means that
5x + 6y = 90 - - - - - - - - - - - -2
Multiplying equation 1 by 5 and equation 2 by 4, it becomes
20x + 35y = 415
20x + 24y = 360
Subtracting, it becomes
11y = 55
y = 55/11 = 5
Substituting y = 5 into equation 1, it becomes
4x + 7 × 5 = 83
4x + 35 = 83
4x = 83 - 35 = 48
x = 48/4 = 12
<u>Answer:</u>
Zero
<u>Step-by-step explanation:</u>
We are given the following expression and we are to determine what is the sign of its product:
One of the three terms in the expression is positive while one is negative. So if we start multiplying the two terms from the left side. we will get a negative number.
But when we will multiply it with zero, the whole product will become zero as anything times zero is always zero. Therefore, answer will be zero.
In getting the scale factor, use the formula:
Scale factor = big / small
Scale factor = 8 / 2
Scale factor = 4 units
