Answer:
It is the experimental condition.
Step-by-step explanation:
In the experiment given in the question, the amount of sleep is the independent variable and the number of photographs they remember is the dependent variable because it depends on the amount of sleep.
The 8 hours of sleep, which creates the difference in the experiment between the control group and the test group, is the experimental condition.
The experimental condition is the variable that is changed to let the researcher observe the effects on the dependent variable.
I hope this answer helps.
The answer is the first option
y=3/2x+5
I would go with
G: 4 cm
Or
J: 8 cm
Let me know if you get it correct! :)
Answer:
Density is defined as:
Density = mass/volume.
We know that:
For liquid A:
Density = 70kg/m^3
Mass = 1400kg
Then the volume is:
Volume = mass/density = (1400kg)/(70kg/m^3) = 20 m^3
For liquid B:
Density = 280 kg/m^3
Volume = 30m^3
We can find the mass of liquid B as:
mass = density*volume = (280kg/m^3)*(30m^3) = 8400 kg
We know that liquid C is a mixture of liquid A and B.
Then the mass of liquid C will be equal to the sum of the masses of liquid A and B, then:
Mass of liquid C = 1400kg + 8400kg = 9800kg
The same happens for the volume, then:
Volume of liquid C = 30m^3 + 20m^3 = 50m^3
Then the density of liquid C is:
Density of liquid C = (9800kg)/(50m^3) = 196 kg/m^3
It is an isosceles triangle
