The temperature at a mountain base camp was −3 degrees Celsius on Monday. Tuesday morning, the temperature was 2 degrees Celsius

kotegsom [21]

It is -3 to start off with, on Monday. On Tuesday morning it would be -3 - 2 degrees, = -5 degrees. By Tuesday evening it was 4 degrees lower than in the morning, so -5 - 4 degrees = -9 degrees on Tuesday evening.

Answer:

Final answer is A. $P(A^c)=\frac{4}{7}$

Step-by-step explanation:

From table we see that there are 7 places in the list.

Event A = The place is city.

Then $A^c$ indicates the place is NOT city.

From table we see that there are 4 names "India, Peru, Canada, Mexico" which are not city.

Hence probability that the chosen place is not city is given by:

$P(A^c)=\frac{4}{7}$

Hence final answer is A. $P(A^c)=\frac{4}{7}$

Which ordered pair makes both inequalities true?

kvasek [131]

Answer:

(3, 0)

Step-by-step explanation:

Given the inequality y > -2x + 3 and y ≤ x - 2

The graph of the inequalities are plotted using the geogebra graphing online calculator.

The portion of the graph that is shaded with dark blue, represents the portion that supports the equation.

All the ordered pair points given in the question are also labelled in the graph.

From the graph we can see that only point (3, 0) falls in the area that supports the equation. Hence (3, 0) makes both inequalities true.
