Answer:
a. Concentration of nitrogen in water draining from fertilized lands
b. Quantitative
c. Water draining from fertilized lands
Step-by-step explanation:
a. Here we are evaluating the Concentration in miligrams of Nitrogen per liter of water, that drains from fertilized lands.. So thats what is defined as the variable.
b. When we talk about qualitative variblaes, we refer to variables that we can't define with numbers. For example the colour of a car, that's a qualitative variable. In this problem, can put a number on the nitrogen concetration. When we can measure the variable with numbers we consider it to be a quantitative variable. Therefore this is a quantitative variable
c. The implied population is the population where we want to interfer the analysis. In here we want to know the concentration of water draining from fertilized lands. So we are using random samples from a lake, and we extrapolate that analysis to a bigger universe, that it´s the water draining from fertilized lands

Step-by-step explanation:
Considering the hang time equation, it is found that Player 1 jumped 0.68 feet higher than Player 2.
<h3>What is the hang time equation?</h3>
The hang-time of the ball for a player of jump h is given by:

The expression can be simplified as:

For a player that has a hang time of 0.9s, the jump is found as follows:




h = 3.24 feet.
For a player that has a hang time of 0.8s, the jump is found as follows:




h = 2.56 feet.
The difference is given by:
3.24 - 2.56 = 0.68 feet.

Answer:
Vertical shift is 2 units top and horizontal shift is
units to the right
Step-by-step explanation:
Consider the function f(x) = a cos(bx + c) + d.
In this graph, the horizontal shift is -c/b and the vertical shift is d.
Let's compare our graph, f(x) = -3 cos(2x - π) + 2 with this graph.
Here, a = -3, b = 2, c = -π and d = 2.
So, vertical shift = d = 2 units top and
horizontal shift =
units to the right.
Answer:
Yes
Step-by-step explanation:
If no number was chosen by more than 3 people and more people chose the number 5 than the number 4, then in the worst scenario (least amount of people chose the number 1) the number 4 was chosen 2 times and the number 2, 3 and 5 were chosen 3 times. That makes a total of 3*3+2 = 11, so 1 person choose the number 1. This was the worst scenario, that guarantees that at least 1 person choose the number 1.
