Answer:

Yes it is biased, its not fair!

Step-by-step explanation:

If you ask 20 boys who are playing football what their favorite sport is, they would most likely say football. They playing football during their free time at school, so that is probably their favorite sport (why would you play football if you didn't enjoy doing so?).

Hatshy [7]

The expected enrolment in 7 years is 1845.

<h3>What is the expected enrolment?
</h3>

The formula for calculating future value of the number of students is an exponential equation with this form:

FV = P (1 + r) ^n

FV = Future population
P = Present population
R = rate of growth of the population
N = number of years

1500 x (1.03)^7 = 1845

Answer:

x = -0.17 and x = -5.83

Step-by-step explanation:

We are asked to solve the quadratic equation

$x^2+6\,x+1=0$

We use the quadratic formula using a = 1, b = 6 and c = 1

for a general quadratic equation of the form: $ax^2+bx+c=0$

Then, the solutions are given by;

$x=\frac{-6+/-\sqrt{36-4\,(1)\,(1)} }{2} =\frac{-6+/-\sqrt{32} }{2}$

which produces the two following answers (rounded to two decimals):

x = -0.17 and x = -5.83

In the parking lot there are 1960 convertibles and 490 minivans, for a total of 2450 cars all together what is the ratio of cars

Sidana [21]

Answer: 5:4

Step-by-step explanation:

Given : The number of convertibles = 1960

The number of minivans = 490

Total cars = 2450

The ratio of A to B can also be written as $\dfrac{A}{B}$ .

The ratio of cars to convertibles = $\dfrac{\text{Number of cars}}{\text{Number of convertibles}}$

$=\dfrac{2450}{1960}\\\\=\dfrac{5}{4}\ \ \ \text{[Simplest form]}$

Hence, the ratio of cars to convertibles = 5:4
