Answer:
The population mean (μ) = 26.
Step-by-step explanation:
a) Data and Calculations:
The population characteristics = 20 and 36
Total population of interest = 56 (20 + 36)
Number of groups in the population = 2
Therefore, the population mean (μ) = 56/2 = 28
b) Based on the parameters given in this example, the population mean equals the average of the group characteristic (attention span of individuals in minutes) or item of interest. The population mean is calculated by adding the values of the group characteristic and then dividing the result by the number of values.
The absolute value of -5 is 5, and the absolute value of 5 is also 5. ∣ a + b i ∣ = a 2 + b 2 . |a+bi| = \sqrt{a^2 +b^2}.
Answer:
175 ml
Step-by-step explanation:
you will have to multiply 700 by .25 as that is the rate that it's evaporating.
Usually "of" means to multiply
Therefore:
700 x 0.25 = 175
Length = 3cm
1/2 cm cube = 3 ÷ 1/2 = 3 x 2 = 6
Width = 4cm
1/2 cm cube = 4 ÷ 1/2 = 4 x 2 = 8
Height = 5cm
1/2 cm cube = 5 ÷ 1/2 = 5 x 2 = 10
Number o 1/2 cubes = 6 x 8 x 10 = 480
Answer:
$17,281.12
Step-by-step explanation:
28,500 * (.92)^x
x - amount of years after 2012
.92 - 100-8 = 92 which is the percent of the price the previous year
Calculator needed.
28,500 * .92^6
28,500 * ~.60636
17,281.1175383
Round up to 17,281.12
