Answer:
,
,
and 
Step-by-step explanation:
Here, x represents the number of hours Zoe spent running on her wheel and y represents the number of hours spent scratching her cage.
Julie was awoke for at least an hour running on her exercise wheel and scratching the of her cage.
⇒ 
She ran on her wheel at least twice as long as she scratched at the corners of her cage.
⇒ 
Also, She spent more than 1/4 hour running on her wheel.
⇒ 
And, we know that number of hours can not be negative.
⇒
Therefore, the complete system of inequality which shows the given situation is,
,
and
, 
Note: the feasible region ( covered by the given system) is shown in the below graph.
Answer:
66.6%
Step-by-step explanation:
The probability that it is blue or odd, would be the quotient between the marbles of these characteristics and the total number of marbles.
Now, we know that there are four blue marbles altogether. The odd ones, in the case of the red ones since there are eight, are the marbles 1,3,5,7 and in the blue ones the odd ones are not counted because they are already included as blue; therefore there are a total of four odd marbles. In total, between odd and blue there are eight marbles.
Which means that the probability is as follows, knowing that there are a total of 12 marbles:
8/12 = 0.666, that is, there is 66.6% chance that the marble that is drawn is blue or an odd number.
Answer:
This example illustrates Homeostasis.
Step-by-step explanation:
Consider the provided information.
On a very hot summer day and a few months later on a very cold winter day, you go outside and take your temperature. Each time your body temperature is 37 degrees Celsius that means your body's tissues, and cells helps you to attain the stability and constancy required for proper functioning.
The medical definition of Homeostasis is:
Homeostasis is a property of tissues, and cells that helps the stability and constancy required for proper functioning to be maintained and regulated. it is a state maintained through the continuous adjustment of biochemical and physiological processes.
The provided example explain the process of Homeostasis.
Thus, this example illustrates Homeostasis.
