Using the slope-intercept form, the score is expected to increase by 15 units

<h3>Equation of Line</h3>

To solve this problem, we have to use the equation of line with the slope to determine his score in the game.

The slope-intercept form of an equation is given as

y = mx + c

m = slope
c = y-intercept

Taking the points that give line of best fit;

The points are (6, 50) and (12, 80)

m = y₂ - y₁ / x₂ - x₁

m = 80 - 50 / 12 - 6

m = 5

Taking any point

y = mx + c

80 = 5(12) + c

80 = 60 + c

c = 20

The equation is y = 5x + 20

If he decides to play 15 minutes longer;

y = 5x + 20 + 15

y = 5x + 35

The score will change by at least 15 units

Answer:

The mean is 0.54 and the standard deviation is 0.0135.

Step-by-step explanation:

i) the mean of the sampling distribution is 0.54

ii) the mean for the sampling distribution, p = 0.54

iii) therefore for the sampling distribution, q = ( 1 - 0.54) = 0.46

iv) the sample size of the distribution, n = 1356

v) $the\hspace{0.1cm} standard\hspace{0.1cm} deviation\hspace{0.1cm} s = \sqrt{\frac{p\times q}{n} } = \sqrt{\frac{0.54\times 0.46}{1356} } = 0.0135$

Answer:

$8,000

Step-by-step explanation:

Let the store earned $x in December.

Therefore,

Money spent to buy new inventory $=\frac{1}{4} x$

Remaining money $= x - \frac{1}{4} x =\frac{3}{4} x$

Money used to pay bills $=\frac{1}{2} \times \frac{3}{4} x=\frac{3}{8} x$

Money still left over = $3,000

Total money earned in December $= \frac{1}{4} x+ \frac{3}{8} x+3,000$

$\therefore x= \frac{1}{4} x+ \frac{3}{8} x+3,000$

$\therefore x= \frac{2}{8} x+ \frac{3}{8} x+3,000$

$\therefore x= \frac{5}{8} x+ 3,000$

$\therefore x- \frac{5}{8} x=3,000$

$\therefore \frac{8x-5x}{8} =3,000$

$\therefore \frac{3x}{8} =3,000$

$\therefore x =3,000\times \frac {8}{3}$

$\therefore x =1,000\times 8$

$\therefore x =\$8,000$

Thus, total money earned in December is $8,000.
