Using the probability concept, the number of blue balls you need to add is:
D) 5.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
A probability of 0.5 is reached if the number of red balls is the same as the number of blue balls. Current the difference is of 7 - 2 = 5, hence 5 blue balls must be added.

Answer:
1.8 km
Step-by-step explanation:
The scale on the map is 1 : 15000.
This means that every 1 cm on the map is equal to 15000 cm on the ground.
12 cm on the map will therefore be:
12 * 15000 = 180000 cm
Let us convert to kilometres:
100000 cm = 1 km
180000 cm = 180000 / 100000 = 1.8 km
12 cm on the map will be 1.8 km on the ground.

Answer:
f(2) = 10
Step-by-step explanation:
Simply just plug in 2 into the equation
f(2) = 3(2)² - 2
f(2) = 3(4) - 2
f(2) = 12 - 2
f(2) = 10
And we have our final answer!
