An environmentalist wants to find out the fraction of oil tankers that have spills each month.
Anastasy [175]

Answer:

The estimate of the proportion of oil tankers that had spills is 0.25.

Step-by-step explanation:

Proportion of oil tankers that had spills:

1036 tankers.

777 did not have spills.

So 1036 - 777 = 259 had spills.

The proportion is:

p = \frac{259}{1036} = 0.25

The estimate of the proportion of oil tankers that had spills is 0.25.

Could someone please help me with this thank you very much
elena-s [515]

Answer:

Answer for #10:

y = 2 \: and \: x = 1

Answer for #1:

x = 2 \: and \: y =  - 1

Step-by-step explanation:

In order to solve a simultaneous equation using the substitution method you have to:

Use one of the equation and substitute it into the other equation, in this case equation <em>B</em><em> </em>was substituted into equation <em>A</em><em>.</em>

<em>equ. \: a = (2x - 3y = 7) \\ equ. \: b = (x = 1 - y)</em>

Therefore since x = 1 - y, equation A would be:

2(1 - y) - 3y = 7 \\ (2 - 2y) - 3y = 7 \\  - 2y - 3y = 7 - 2 \\  - 5y = 5 \\ y =  - 1 \: and \: x = 2
