What is meant by​ confounding?

Mathematics
1 answer:
ankoles [38]3 years ago
7 0

Answer:

a)

Step-by-step explanation:

In a study, if we want to measure of establish a relation between two variables, we say that there is a confounding variable when there is a third variable that is having an effect on our original two variables but this third variable wasn't originally measured in our study. Therefore our results are misleading because the relation between our two variables is being influenced by the confounding one.

This is why the correct answer would be the a) An explanatory variable has a great effect on a response variable. And this causes a misleading interpretation between the two variables.

choli [55]

Answer:

The length of the ladder  = 6.5077 ft

Step-by-step explanation:

Given A ladder leans against the side of a house

Given the angle of elevation of the ladder is 68° when the bottom of the ladder is 16 ft from the side of the house

Let 'C' be the point of observation.

Given CA= 16 ft

 From right angle triangle

     

     

     x = 16 × cos 68°

    x = 16 × 0.4067

    x = 6.5077

  x = 6.5 ft

The length of the ladder = 6.5 ft

Can somebody help me out? I’ll mark as brainliest.
Fofino [41]

Answer:

f(x) = -5x - 14

Step-by-step explanation:

this table represent a straight line : y = mx +c

first find m which is the slope

m = (-24 - -19)/(2-1)  = -5

then find c

-19 = -5(1) + c , c = -14

thus f(x) = -5x -14

If one real number is equal to a second real number, and the second real number is equal to a third real number, then the first
svet-max [94.6K]

Answer: In particular, let’s focus our attention on the behavior of each graph at and around . 2 and x= -1 for x < 2. There are open circles at both endpoints (2, 1) and (-2, 1). The third is h (x) = 1 / (x-2)^2, in which the function curves asymptotically towards y=0 and x=2 in quadrants one and two."

Step-by-step explanation: I think this is the problem ur on
