Answer:
Population
Step-by-step explanation:
In mathematics, when we talk about the people, places, or things under consideration, we are referring to the population. The Population is the entire sum of objects in a study. When a researcher wants to study factors that concern a particular set of people, places, or things, the group under study is the population. For example, the researcher might want to do a study on the amount of food consumed by Brazilian students in the year 2019. The Brazilian students represent the population, because they are the group of people being studied.
The population under study might sometimes be difficult to study as a whole. For example, the study of the entire Brazilian students might be cumbersome. In such cases, a sample can be drawn from the population and studied, or the population narrowed down a little more, so that it can be easily studied.
For the circle of 3x² + 3y² = 75, the radius would be 5, and the center would be (0, 0)
This is because, usual circle equations have only 1 x² and y², so you can divide all terms by 3 to make the equation look normal. This gives you x² + y² = 25.
Since there is nothing being added or subtracted to the x and y values, the center is (0, 0), and the radius is the square root of whatever the values equal, which is √25 = 5.

Answer:
Answer:
A = Full bottle can fill 34 ounces water and 27.2 ounces left in the bottle
Step-by-step explanation:
Full bottle: 100%
6.8 ounces: 20%
100% / 20% = 5
Full bottle = 6.8 x 5 = 34 ounces
water remain in bottle = 34 -6.8 = 27.2 ounces
B = Answer:
55% or 27.2 ounces
Step-by-step explanation:
If he poured out another 25% out of the 80% percent that was there he would have 55% or 27.2 ounces.
The probability that they both only speak Spanish is P = 0.005
<h3>How to find the probability?</h3>
There are 50 people.
We know that:
- 31 of these speak French.
- 2 speak French, German, and Spanish.
- 4 speak French and Spanish.
- 7 speak German and Spanish.
- 8 speak any of the lenguages.
- 10 speak german (and also other lenguages).
Then, the number that speaks only Spanish is:
50 - (31 + 10 + 8 - 3) = 4
(this is, the total number of people minus the ones that speak the other (or neither) lenguages, the "-3" appears there because 3 of the ones that speak German also speak French)
Then the probability that the first randomly selected person speaks Spanish is equal to the quotient between the number that speaks Spanish and the total number:
p = 4/50
For the next person we compute the probability in the same way, but this time there are 3 people that talk Spanish and 49 people in total:
q = 3/49
The joint probability is the product of the two individual ones:
P = (4/50)*(3/49) = 0.005
