Answer:

124%

Step-by-step explanation:

We can find the percent of the goal that she achieved while dividing the amount of time she exercised by the time she set as a goal. So, we have to figure out the value of 93/75. This is equivalent to 1.24. We can find 1.24 as a percentage by moving the decimal point over 2 (124) and then adding a percentage sign (124%). And that's the answer.

Hopefully that's helpful and all makes sense! :)

Answer:You have roughly the same chance of being called as anyone else living in the United States who has a telephone. This chance, however, is only about 1 in 154,000 for a typical Pew Research Center survey. To obtain that rough estimate, we divide the current adult population of the U.S. (about 235 million) by the typical sample size of our polls (usually around 1,500 people). Telephone numbers for Pew Research Center polls are generated through a process that attempts to give every household in the population a known chance of being included. Of course, if you don’t have a telephone at all (about 2% of households), then you have no chance of being included in our telephone surveys.

The following scatter plot represents the height of a basketball in seconds during a free throw shot.
zavuch27 [327]

The function is not treated as linear because whenever we throw the thing in the air it traces the path of the parabola which is quadratic. Then the quadratic equation is y = -1.25x² + 7.35x + 3.2.

<h3>What is a quadratic equation?</h3>

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

The following scatter plot represents the height of a basketball in seconds during a free throw shot.

(a) A student chose to model the data with the function, y = 0.9286x + 9.0571 . Then the function is not treated as linear because whenever we throw the thing in the air it traces the path of the parabola which is quadratic.

(b) Write a function

We know that the quadratic equation is given as ax² + bx + c = y

This will pass through the points (1, 9.3), (2, 12.9), and (3, 14). Then we have

\rm a + b + c = 9.3  \ \ \  \ \ \ \ ...1\\\\4a + 2b + c = 12.9 \ \  \ ...2\\\\9a + 3b + c = 14 \  \ \ \ \ \ ...3

On solving the equations 1, 2, and 3. Then we have

a = -1.25, b = 7.35, and c = 3.2

Then the quadratic equation will be

y = -1.25x² + 7.35x + 3.2

More about the quadratic equation link is given below.
