Answer: it is a categorical variable,a nominal,a quantitative variable and finally, a discrete variable.

Step-by-step explanation:

A categorical data are data arranged in group. The poll conducted concerning physical sport for children is countable in numbers and it can be place in groups which makes the poll categorical. Since it is numerical or nominal, it is quantitative because is measurable. Finally it is discrete variable since it assume whole numbers and not fractional

Find the inverse of the given function.

kodGreya [7K]

For this case we must find the inverse of the following function:

$f (x) = - \frac {1} {2} \sqrt {x + 3}$

We follow the steps below:

Replace f(x) with y:

$y = -\frac {1} {2} \sqrt {x + 3}$

We exchange the variables:

$x = - \frac {1} {2} \sqrt {y + 3}$

We solve for "y":

$- \frac {1} {2} \sqrt {y + 3} = x$

Multiply by -2 on both sides of the equation:

$\sqrt {y + 3} = - 2x$

We raise both sides of the equation to the square to eliminate the radical:

$(\sqrt {y + 3}) ^ 2 = (- 2x) ^ 2\\y + 3 = 4x ^ 2$

We subtract 3 from both sides of the equation:

$y = 4x ^ 2-3$

We change y by f ^ {- 1} (x):

$f ^ {- 1} (x) = 4x ^ 2-3$

Answer: $f ^ {- 1} (x) = 4x ^ 2-3$

( $\frac{9}{2}$ , 3 )

to calculate the midpoint use the midpoint formula

midpoint = [ $\frac{1}{2}$ (9 + 0), $\frac{1}{2}$ (- 1 + 7)] = ( $\frac{9}{2}$ , 3 )

A company will need 25,000 in 7 years for a new additon. To meet this goal, the company deposits money into an account today tha

Mrac [35]

You can use the simple interest formula
$P = irt$

We need P, which is the primary (or principal) investment, and we know that:

rate = 3% (0.03)
time = 7
i = $25000

So, just plug in and solve:
$I = 25000(0.03)(7)$
$I = 5250$

The company needs to invest $5250 today, to make $25000 in 7 years.
