8 numbers have a sum of 90. Whats the average number?
ehidna [41]

Answer:

\huge\boxed{11.25}

Step-by-step explanation:

When finding the average of a set of numbers, we

  • A) Add up all the numbers
  • B) Divide that sum by the total number of numbers in the data set

Let's represent this with a formula, s being the sum of all numbers, n being the total number of numbers.

\frac{s}{n}

Since we <u>already know the sum</u> and we <u>know how many numbers there are</u> (8), we can substitute inside our expression \frac{s}{n} to find the average.

  • \frac{90}{8}
  • 11.25

Therefore, the average of all these numbers is 11.25.

Hope this helped!

A rock is thrown at 0 seconds from a height of 6 feet. If the parabola representing the height as a function of time has a verte
Korolek [52]

Answer:

The correct option is;

The graph will have a height of 6 feet at 16 seconds

Step-by-step explanation:

The given parameters are;

The start time for throwing the rock = 0 s

The height from which the rock is thrown = 6 ft

The vertex of the parabola = 8 seconds

Given that the vertex is the axis of symmetry, then the time it takes the rock to reach the vertex (8 seconds) from the point (0, 6) will be the same time it takes the rock to reach the point on the other side of the parabola at the same 6 feet which will then have coordinates (8 + 8, 6) or (16, 6) which will be 6 feet in 16 seconds.
