Cocoa plant type 1 yielded 155 bushels per acre last year at a research farm. This year,cocoa plant type 2, planted in the same location, yielded only 123 bushels per acre and
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

Answer 1

Answer:

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".

A 1350 kg car travels at 12 m/s. What is it's kinetic energy

Answers

energy is always transformed from one form to another

energy is not created nor destroyed

so when a car starts moving the chemical potential energy of the car is converted to kinetic energy

kinetic energy is the energy that moving objects possess

kinetic energy formula is as follows

Kinetic energy = 1/2 mv²

where m - mass

v - velocity

substituting these values

K.E = 1/2 x 1350 kg x (12 m/s)²

= 1/2 x 1350 x 144 = 97200 J

the kinetic energy of the car is 97.2 kJ

Hello!

A 1350 kg car travels at 12 m/s. What is it's kinetic energy ?

We have the following data:

m (mass) = 1350 kg

v (velocity) = 12 m/s

KE (kinetic Energy) = ? (in Joule)

Formula to calculate kinetic energy:

$\boxed{KE = (1)/(2) *m*v^2}$

Solving:

$KE = (1)/(2) *m*v^2$

$KE = (1)/(2) *1350*12^2$

$KE = (1)/(2) *1350*144$

$KE = (194400)/(2)$

$\boxed{\boxed{KE = 97200\:Joule}}\:or\:\boxed{\boxed{KE = 97.2\:kJ}}\Longleftarrow(kinetic\:energy)\:\:\:\:\:\:\bf\blue{\checkmark}$

24 is what percent of 800

Answers

24 is what percent of 800

percent mean parts out of 100 so x%=x/100
'of' means multiply or times

24 is what percent of 800 means
24=x/100 times 800
24=800x/100
24=8x
divide both sidse by 8
3=x

answer is 3%
(easy way is 24 out of 800=24/800=3/100=3%)

What ages, in years, does the interval of 80-89 months represent

Answers

Well, there are 12 months in a year, so divide 80 and 89 by 12, which gives you 6 years and a remainder of 8 months, and 7 years with a remainder of 5 months. So your answer is 6 years 8 months- 7 years 5 months.
