A 100-pound person on Earth would weigh about 4 x 4 x 4 x 4 pounds on Jupiter. Evaluate the expression to determine how much a 100-pound person would weigh on Jupiter.

Answers

Answer:

$\text{Weight on Jupiter} = (25)/(64)* (\text{Weight on earth})$

Step-by-step explanation:

A 100 pound person on earth weigh 4×4×4×4 pounds on Jupiter.

4×4×4×4 pounds weight = 256 pounds

Therefore ratio of the weights on earth and Jupiter = 100 : 256

= 25 : 64

Let a person weigh x pounds on Earth therefore the expression which represents the weight of the person on Jupiter will be

$\frac{\text{Weight on Jupiter}}{\text{Weight on Earth}}=(25)/(64)$

$\text{Weight on Jupiter} = (25)/(64)* (\text{Weight on earth})$

he would weigh 25,600 pounds on Jupiter
100 * 4*4*4*4 gives you 25,60p

there was a major freeze. The researchers do not know whether the difference is the
result of the superiority of type 1 or the freeze. What is this an example of? (4 points)
- Bias
- Confounding variable
- Matched-pairs desighs
- The placebo effect
- Replication

Answers

The confounding variable, often described as a confounder or confusing factor, is a dimension in studies looking at a possible causation link, and further calculation can be defined as follows:

It has connected both to the study's apparent cause and its ostensible impact.
It can be difficult to differentiate between both the genuine relationship between the independent variable and the effect of a contextual factor.
It is an external factor that alters the impact of variables to utilized to sway the findings of an experiment.

Therefore, the final answer is "Confounding variable".
