Answer:

56 people drink 3 cups daily

Step-by-step explanation:

What's the total number of people that drink 3 cups?

Total number of people = 400

7 / 10 were asked said yes

Number of people that said yes = (7 / 10) × 400 = 280

280 people drink tea.

20% of 280 people drink 3 cups daily, whats the number = ?

20% of 280 = ?

20 / 100 = x / 280

(20 × 280) = (100 × x)

5600 = 100x

X = 5600 / 100

X = 56 people

56 people drink 3 cups of tea daily.

Answer:

The Type of Drink (Gatorade or Water)

Step-by-step explanation:

The Independent variables which causes the measured difference or change in the output of the dependent variable. In an experiment, the treatment administered to subjects which will most likely result into differing output are called the independent variables. In the scenario described above, the independent variable is the type of drink taken by the athlete, this drink will cause a change on the output, (how far an athlete can run) which is the dependent variable in the experiment.

What should the next number be? 100 96 104 88 120 56
riadik2000 [5.3K]

100 ---> 96 is -4

96 ---> 104 is +8

104 ---> 88 is -16

88 ---> 120 is +32

120 ---> 56 is -64  

So first we go down by 4, then up by 8, then down 16, then up 32, then finally down 64.  

The pattern of numbers is: -4, +8, -16, +32, -64  

Notice it's the powers of 2:  

2^2 = 4

2^3 = 8

2^4 = 16

2^5 = 32

2^6 = 64

each term doubles. Also each term alternates in sign. One is positive, then the next is negative and so on.  

The last difference is -64, which doubles to -128. Change the sign to positive to get +128  

Add 128 to the last term of 56 to get

128+56 = 184  

Therefore, the final answer is 184

What is the lowest value of the range of the function
Alex Ar [27]

The lowest value of the range of the function shown in the graph is -2.

<h3>What is range of a function?</h3>

The range of a function is the set of its possible output values.

In other words, the range of a function is the complete set of all possible resulting values of the dependent variable (y), after we have substituted the domain or independent variables.

The range value are the y values of the graph shown.

Therefore, the lowest value of the range of the function shown on the graph is -2.
