Answer:

The solution to the quadratic equations are:

$x=3\sqrt{3}i,\:x=-3\sqrt{3}i$

Step-by-step explanation:

Consider the provided quadratic equation.

$x^2+27=0$

Subtract 27 from both sides.

$x^2+27-27=-27$

$x^2=-27$

$x=\pm \sqrt{-27}$

$x=\pm 3 \sqrt{3}i$ ∴i=√-1

Hence, the solution to the equation are:

$x=3\sqrt{3}i,\:x=-3\sqrt{3}i$

Answer:

The IQR is given by:

$IQR = Q_3 -Q_1 = 28-18= 10$

If we want to find any possible outliers we can use the following formulas for the limits:

$Lower= Q_1 - 1.5 IQR$

$Upper= Q_3 + 1.5 IQR$

And if we find the lower limt we got:

$Lower= Q_1 - 1.5 IQR= 18-1.5*10 = 3$

$Upper= Q_3 + 1.5 IQR= 28+1.5*10= 43$

So then the left boundary for this case would be 3 days

Step-by-step explanation:

For this case we have the following 5 number summary from the data of 144 values:

Minimum: 9 days

Q1: 18 days

Median: 21 days

Q3: 28 days

Maximum: 56 days

The IQR is given by:

$IQR = Q_3 -Q_1 = 28-18= 10$

If we want to find any possible outliers we can use the following formulas for the limits:

$Lower= Q_1 - 1.5 IQR$

$Upper= Q_3 + 1.5 IQR$

And if we find the lower limt we got:

$Lower= Q_1 - 1.5 IQR= 18-1.5*10 = 3$

$Upper= Q_3 + 1.5 IQR= 28+1.5*10= 43$

So then the left boundary for this case would be 3 days

For f (x) = 4 x +1 and g(x) = x^2- 5, find (g/f)(x)

Lady bird [3.3K]

Answer:

The answer is: $\frac{x^2-5}{4x+1}$

Step-by-step explanation:

We are given: $f(x)=4x+1$ and $g(x) = x^2-5$

We need to find $(g/f)(x)$ .

Simply divide $g(x)$ and $f(x)\\$ .

Which equates to:

$(g/f)(x)= \frac{g(x)}{f(x)} =\frac{x^2-5}{4x+1}$

This cannot be simplified further, so it is the answer.
