Answer:

$1,000,000 \: {m}^{3}$

Step-by-step explanation:

$0.001 \: {km}^{3} \\ \\ = 0.001 \times {(1000)}^{3} \\ \\ = 0.001 \times 1,000,000,000 \\ \\ = 1,000,000 \: {m}^{3}$

Natali [406]

Answer:

Value of p is 3

Step-by-step explanation:

One of the root is 1.

So, putting 1 in the place of x in the given equation,

px²-4x+3p-8=0

or, p-4+3p-8=0

or, 4p-12=0

or, 4p=12

or, p=3

Answer:

$\sigma = 121.53$

Step-by-step explanation:

Required

The population standard deviation

First, calculate the population mean

$\mu = \frac{\sum x}{n}$

This gives:

$\mu = \frac{148+ 329+ 491 +167+ 228+285+ 441}{7}$

$\mu = \frac{2089}{7}$

$\mu = 298.43$

The population standard deviation is:

$\sigma = \sqrt{\frac{\sum(x - \bar x)^2}{n}}$

So, we have:

$\sigma = \sqrt{\frac{(148 - 298.43)^2 + ..........+ (441- 298.43)^2}{7}}$

$\sigma = \sqrt{\frac{103387.7143}{7}}$

$\sigma = \sqrt{14769.6734714}$

$\sigma = 121.53$

A fish population in a lake decreases by 2% each year. What is the common ratio? (Write your answer as a decimal)

galina1969 [7]

Answer:

the common ratio is 0.98.

Step-by-step explanation:

A fish population in a lake decreases by 2% each year. We are asked to find the common ratio.

The decrease of population of fish 2% annually means the population becomes next year 100% - 2% = 98%

Therefore, the common ratio would be 98%. Upon converting 98 percent to a decimal we will get,

98% = $\frac{98}{100}=0.98$

Therefore, the common ratio or decay factor is 0.98.
