Natalka [10]

Answer:

4% probability that fazio selects a striped jersey both times.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem:

For each jersey, there are 2+5+3 = 10 possible options, two of which are striped.

So twice 2/10

p = (\frac{2}{10})^{2} = \frac{4}{100}

4% probability that fazio selects a striped jersey both times.

According to the data reported by the New York State Department of Health regarding West Nile Virus for the years 2000-2004, the
hjlf

Answer:

31 human cases.

Step-by-step explanation:

The least squares line equation for the number of reported dead birds (x), versus the number of human West Nile virus cases (y) is

y = -10.2638 + 0.0491x

If the number dead birds reported in a year is 844, then we have to find the numbers of human cases of West Nile virus.

To find the numbers we will plug in the value of x = 844 in the linear equation.

y = -10.2638 + 0.0491(844)

  = -10.2638 + 41.4404

  = 31.1766

  ≈ 31

Therefore, 31 human cases can be expected.
