- In this study researcher observes the variables without influencing them.
Here, A research company uses a device to record the viewing habits of about 2500 households (that includes different persons such as adults , children and seniors )
The data collected today(at a single point in time).
If it is used to determine the proportion of households tuned to a particular children's children's program.
The type of observational study is described in the problem statement : "cross-sectional"
Answer:
5.8
Step-by-step explanation:
the distance formula is
d =sqrt( (x2-x1)^2 + (y2-y1)^2 )
= sqrt ( (-5 - -2) ^2 + (-1 - -6)^2 )
= sqrt( (-5 +2) ^2 + (-1 +6)^2 )
= sqrt( (-3) ^2 + (5)^2 )
= sqrt( 9+25)
= sqrt(34)
=5.830951895
Rounding to the nearest tenth

Answer:
g= 60°
i= 70°
h= 50°
Step-by-step explanation:
g=180-120 = 60°
i= 180-110 = 70°
h=180-60-70 = 50°
hope this helps =)
Kindly rate and mark brainliest. Thank you.
The answer is 5 because first, you make the expression 15/6*7-39 then simplify so that it becomes 15/42-39 simplify again to get 15/3 which equals 5
