The research question is important to a researcher as it helps in solving the issue that the researcher wants to solve.
- The research topic will be "Social media has an effect on the behavior of children".
- The research question will be "what effect does social media has on the effects of the behavior of children".
- The null hypothesis will be "there is no statistical significance between social media and children's behavior".
- The alternative hypothesis will be "there is a statistical significance between social media and children's behavior".
- The null hypothesis will be rejected when the p-value is equal to the significance level or it's less than it.

Step-by-step explanation:
multiply both sides
Question:
The image of the question is attached below.
Answer:
x = 40
Solution:
Given ΔVDG
ΔVNG.
DG = 207, NQ = 138, GQ = 60, QV = x
In two triangles are similar, then the measures of the corresponding sides are in proportional to each other.


Do cross multiplication, we get



Divide by 207 on both sides of the equation, we get


⇒ x = 40
⇒ QV = 40
Hence the value of x is 40.
Answer:

Step-by-step explanation:
Given


Required
Represent the additional time needed as an inequality
Convert the previous time to minutes




Let the additional time be t
<em>This means that she needs to run at least t minutes to beat her previous record</em>
<em />
To beat her previous record, the sum of current time and x must be less than her previous time. i.e.

This can be rewritten as:
