Answer:
x = 6
Step-by-step explanation:
Given that x and y vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 25 when y = 100 , then
100 = 25k ( divide both sides by 25 )
4 = k
y = 4x ← equation of variation
When y = 24 , then
24 = 4x ( divide both sides by 4 )
6 = x
There are to be exact only 2 ways to answer this equation because of the way math was made.
1.y-4.90 = 2.4(x-1) 2. 24x-10y= -25
Step-by-step explanation:
The point-slope form of an equation is written as ;
y-y₁ = m(x-x₁) where the focus is on the slope of the line and a point on the line.
In this case, y-4.90 = 2.4(x-1)
The standard form an equation is written as :
Ax+By=C ,where x and y are variables and A,B and C are integers.
In this case; 24x-10y= -25

Answer: (C) $104
<u>Step-by-step explanation:</u>
The Annual Expenses are:
- Car Insurance = $850
- <u> Books </u>= <u>$400 </u>
Total = $1250
There are 12 months in a year so divide the Annual Expense by 12:
<u> 1 0 4</u>
12 ) 1250
<u> -12↓↓ </u>
5↓
<u> - 0↓ </u>
50
<u> - 48 </u>

Answer: Observational ; does not
Step-by-step explanation: The main distinguishing factor between an experimental study and an observational study lies in the administration of treatment to the participant of the study. In experimental study, some or all the participant in the study are subjected or exposed to a certain treatment and their response to such treatment. ON THE OTHER HAND, Observational study is usually employed when there is a need to gather information on a particular subject matter without directly influencing the participants. In the scenario above, participants were not given any TREATMENT as they were only required to gather information and not to measure the effect of a treatment.
