Answer:

1). Mean: 14.2

Median: 13.5

Step-by-step explanation:

To calculate the mean, sum all values and divide by the number of values:

(13+16+14+17+13+12) / 6 ≈ 14.2

To calculate the median, order the values from small to large and take the middle value. If there is no middle. average the two values in the middle:

12,13,<u>13,14</u>,16,17

The median is (13+14)/2 = 13.5.

Using this explanation you should be able to find the rest.

Ashley solved the equation for m using the following steps.

Natalka [10]

Answer:

Ashley should have added 4.5 to both sides.

Step-by-step explanation:

Given expression:

$-4.5+m=17$

Ashley's solution:

Subtracted 4.5 to both sides and got,

$m=12.5$

Correct solution:

Adding 4.5 to both sides.

$-4.5+m=17$

$+4.5$ $+4.5$

∴ $m=21.5$

Error made by Ashley was subtracting 4.5 both sides. Instead he should have added 4.5 both sides.

the birth rate in a certain country in 1994 was 14,6 birthd per thousand population. in 2004 the birth rate was 14.32 per thousa

amm1812

Answer:

$y(x)=-0.028x+14.6$

Step-by-step explanation:

Birth Rate in 1994 = 14.6 births per thousand population.

Birth Rate in 2004 = 14.32 births per thousand population.

A linear equation is of the form: y=mx+c

Where:

x=years after 1994
y=the birth rate
m=Yearly Birth Rate

First, we determine the birth rate per year

$m=\dfrac{14.32-14.6}{10-0}\\=\dfrac{-0.28}{10}\\m=-0.028$

Therefore, a linear equation that relates y in terms of x is of the form:

$y(x)=-0.028x+c$

When x=0, y=14.6

14.6=-0.028(0)+c

c=14.6

Therefore, the linear equation that relates y in terms of x is:

$y(x)=-0.028x+14.6$
