Answer:

5°F

Step-by-step explanation:

The starting temperature is 5.

You get this answer when you add 12 to -7.

If the question is saying the temperature dropped 12°F every 8 hours then the answer would be 89°F because you multiply 12 and 8, then add 96 to -7.

Hope this helped a bit? :)

Answer:

H0 : the treatment has no effect

Step-by-step explanation:

The test is formulated as hypothesis . Here the test ist that whether the treatment has  affected or not . So the null hypothesis can be formulated as

H0 : the treatment has no effect

against the claim

Person to get this question right will get brainliest: If I have 4 moles of a gas at a pressure of 5.6 atm and a volume of 12 li
dybincka [34]

Answer:

If i have three moles of a gas at a pressure of 5.6 atm and a volume of 3 liters, what is the temperature ?

We have the following data:

n (number of moles) = 3 moles

P (pressure) = 5.6 atm

V (volume) = 12 L

T (temperature) = ? (in Kelvin)

R (gas constant) = 0.082 atm.L / mol.K

We apply the data above to the Clapeyron equation (gas equation), let's see:

Answer:

The temperature is approximately 205 Kelvin

Find the equation of the sphere passing through P(negative 4 comma 7 comma 6 )and Q(8 comma negative 3 comma 5 )with its center
Juli2301 [7.4K]

Answer: The equation of the sphere is:

(x-2)^2 + (y-2)^2 + (z-5/2)^2 = sqrt(245)/2

Step-by-step explanation:

The centre of the sphere is the midpoint of the diameter, which is

1/2

[(-4,7,6) + (8,-3,5)] =(2,2,5/2)

The length of the diameter is

=sqrt |(8,-3,5) - (-4,7,6)|^2

=sqrt (12^2 + (-10)^2 + (-1)^2)

=sqrt (144+100+1)

=sqrt(245)

so the radius of

the sphere is:

1/2(sqrt(245)) = sqrt(245)/2.

The equation of the sphere is:

(x-2)^2 + (y-2)^2 + (z-5/2)^2 = sqrt(245)/2
