Answer:

3139.5 m²

Step-by-step explanation:

the formula for the volume of a sphere of radius r is V = (4/3)πr³. In this particular case, V = 2098π m³ = (4/3)πr³, and from this we can calculate the radius, r:

2098π m³

r³ = ----------------- = (3/4)(2098 = 1483/5

(4/3)π

Thus r = ∛1573.5 m³ = 11.64 m

Then the surface area is A = 4πr², which in this case is

A = 4(3.14159)(11.64 m)^2 = 1702.6 m² (which is to the nearest tenth).

Answer:

75% of the data will reside in the range 23000 to 28400.

Step-by-step explanation :

To find the range of values :

We need to find the values that deviate from the mean. Since we want at least 75% of the data to reside between the range therefore we have,

$1 - \frac{1}{k^2} =\frac{75}{100}$

Solving this, we would get k = 2 which shows the value one needs to find lies outside the range.

Range is given by : mean +/- (z score) × (value of a standard deviation)

⇒ Range : 25700 +/- 2 × 1350

⇒ Range : (25700 - 2700) to (25700 + 2700)

Hence, 75% of the data will reside in the range 23000 to 28400.

$\frac{ { - 5}^{2} + {10}^{2} }{(2 \times ( - 5) \times 3) + {3}^{3} } = \frac{ - 25 + 100}{ - 30 + 27} = \\ = \frac{75}{ - 3} = - 25$
