Answer:

radius \: of \: earth \:  = 6.4 \times  {10}^{6} \: m  \\ volume  \: of \: a \: sphere =  \frac{4}{3} \pi {r}^{3}  \\  =  \frac{4}{3}  \times 3.14 \times (6.4 \times  {10}^{6} ) ^{3}  \\  = 1.098 \times  {10}^{21}  \:  {m}^{3}  \\ or \\  = 1.098 \times  {10}^{12}  \:  {km}^{3}

PtichkaEL [24]

Answer:

Initial Amount=1

Decay Factor=0.99987

Decay Rate=0.013%

Step-by-step explanation:

If P = 0.99987ᵃ

I. Initial amount

The initial amount is when a=0

P = 0.99987⁰ = 1

The Pressure at Sea Level=1

II. Decay factor

This is like the decay constant. From the model, P = 0.99987ᵃ, the decay constant/factor is 0.99987.

III. Decay Rate = 1-0.99987 = 0.00013

Expressed in Percentage = 0.013%

Does the residual plot indicate that a line is a good model for predicting the height of girls from their ages? Explain.
galben [10]
A plot of residuals (vertical deviations from the regression line) shows the errors or lack of fit, so it would indicate a good fit if the residuals are small, vs. over fit if they are large. Due to age related growth short pre teen, and a plateau after age 21, I would expect a linear regression would offer estimate age 5.5 years.
