David recently read a scholarly article about a correlational study which showed that families who eat more meals together tend to have children with fewer discipline problems. Since David's sons has been acting out a lot, David decides that he can solve the problem just by having the family eat dinner together every night. what error(s) did David make?a) Attributing causes where none have been foundb) Overgeneralizing based on the little informationc) Failing to distinguish between group results and individual needsd) Failing to consider the source of information

A, C

Explanation:

David is wrongly attributing the lack of the family eating together as the cause of his sons acting out, he is attributing cause where none have been found. His first approach should be to find out the reason why his sons are acting out.

The second error David is making is that research especially social science study results dwell on majority, an average and at such may not necessarily apply to everyone as individual needs deffer and what worked for a particular group may not necessarily work for another.

x = 7

step-by-step explanation:

equating the expression for area to the given area

2x² - 7x - 4 = 45 ( subtract 45 from both sides )

2x² - 7x - 49 = 0 ← in standard form

to factor consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 49 = - 98 and sum = - 7

the factors are - 14 and + 7

use these factors to split the middle term

2x² - 14x + 7x - 49 = 0 ( factor the first/second and third/fourth terms )

2x(x - 7) + 7(x - 7) = 0 ← factor out (x - 7)

(x - 7)(2x + 7) = 0

equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

2x + 7 = 0 ⇒ 2x = - 7 ⇒ x = -

thus the positive value for x is x = 7

your answer is a hope that .
