Answer:
Correct option is : 1) It has a slope of 7 and a y-intercept of -2.
Step-by-step explanation:
The given function is :
.....1
The general form of equation of a linear function is given by :
.....2
where, y is the dependent variable, x is the independent variable, m is the slope of the function and c is the y-intercept.
On comparing equations 1 and 2, we get:
m = 7,c = -2
Thus, we can conclude that : Slope of equation is 7 and y-intercept is -2.
Thus, only option 1 satisfies the given solution.
7 - 35 - 7x - 9x
-28 -16x

Answer:
c)
Step-by-step explanation:
The definition of an observational study is: one where researchers observe the effect of a risk factor or an intervention but they do not try to change who is exposed to the factor.
In this particular example, the researchers administered a questionnaire to 391 twelve-year-old and concluded that the body mass index of the adolescents who had a supply of sugary snacks in their bedroom was significantly higher than that of the adolescents who did not have a supply of sugary snacks in their bedroom.
This is not an observational study because the researchers actually administered a questionnaire and analyzed the results. To be an observational study the individuals would have been observed without any intervention (the questionnaire could have had an effect on the adolescents changing their habits)
Answer:
183 meters
Step-by-step explanation:
A 1:750 scale model means that each cm on the model corresponds to 750 cm of the actual Sydney Opera House. If the model is 24.4 centimeters long, the actual Opera House has a length of:
The actual length of the Sydney Opera House is 183 m.
