Answer:
Median: 0.5
Step-by-step explanation:
Arrange the following set of data from least to greatest:
0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.9
then find the middle number (the median).
since there are seven numbers in the data set we divide it, by doing this:
{0.2, 0.3, 0.4} 0.5 {0.6, 0.7 0.9}
Therefore, the median for the data set is 0.5!

Answer:
628.32 is the volume
Step-by-step explanation:
V=3.14·r²·h
in your case it is A
Answer:
50.2 m²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius , here r = 4 ), thus
A = π × 4² = 16π = 16 × 3.14 ≈ 50.2 ( to the nearest tenth )
You are trying so solve
<span><span>3^x</span>=8</span>
and since 8 is not an integral power of x you need a calculator.
it is <span><span>ln(8)/</span><span>ln(3)</span></span>
or
<span><span><span>log(8)/</span><span>log(3)</span></span></span>
