How to factor quadratic equations

1 answer:

4 0

Step 1: find two numbers that multiply to give ac ( in other words a x c ) and add to give b

step 2: rewrite the middle with those numbers

step 3: factor the first two and last two terms separately

step 4: if you’ve done this correctly, your two new terms should have a clearly visible common factor

and then you’re done! hope this helps!

Elavter of using distuburting propties a. 17×102<br> b. 477×1035 -477×35

V125BC [204]

Answer: a. 1734 b. 477000

Step-by-step explanation:

We know that,

Distributive property : a(b+c) = ab+ac

a. 17 x 102

= 17 (100+2)

= 17 x 100 + 17 x 2 [Distributive property ]

= 1700+34

= 1734

b. 477×1035 -477×35

= 477 (1035-35) [Distributive property ]

= 477 (1000)

= 477000

1.15 GPA and study hours: A survey was conducted on 193 Duke University undergraduates who took an introductory statistics cours

KonstantinChe [14]

Answer:

Step-by-step explanation:

According to the exercise we can say that the explanatory variable will be hours / weeks of study.

The response variable is GPA.

We definitely found that between the variables there is a weak or fragile relationship, neither negative nor positive nor linear.

1.Observational study, since we observe that the only variables that will influence the results of the study are the observations of the students

2.No. This study is observational and its characteristics are not sufficient to conclude that studying more hours leads to obtaining a higher GPA.
