Quadratic functions are functions that has a leading degree of 2. The time that the rocket will hit the ground is after 15.99 seconds

<h3>Quadratic functions</h3>

Quadratic functions are functions that has a leading degree of 2. Given the function that represents the height of the rocket as;

y = -16x² + 247x + 141

The point where the rocket will hit the ground is when the height is at 0 feet that is y = 0.

Substitute

-16x² + 247x + 141 = 0

16x² - 247x - 141 = 0

Factorize

On factorizing, the time that the rocket will hit the ground is after 15.99 seconds

In a continuous series, mean(x) = 80, assumed mean(A) = 60 and<br>EF=40 then find the value of EFd.​
Aneli [31]

Using the given information, the value of Σfd is 800

<h3>Calculating mean using Assumed mean </h3>

From the question, we are to determine the value of Σfd

The formula for mean, using the assumed mean method is given by

\bar x = A + \frac{\sum fd}{\sum f}

Where \bar x is the mean

A is the assumed mean

From the given information,

\bar x = 80

A = 60

\sum f = 40

Putting the parameters into the equation, we get

80 = 60 + \frac{\sum fd}{40}

80-60 = \frac{\sum fd}{40}

20 = \frac{\sum fd}{40}

\sum fd = 20 \times 40

\sum fd = 800

Hence, the value of Σfd is 800
