Answer:

Step-by-step explanation:

90/7=12ish

but it is not 12. you need at lease 7 people on a team, 6 field players, and one goalie. so it would be 11 teams, with 6 people to be spread out.

A line passes through (3, -2) and (6, 2). a. Write an equation for the line in point-slope form. b. Rewrite the equation in stan

koban [17]

Answer:

(a)

Given: A line passes through the points (3, -2) and (6, 2)

Point slope form: An equation of line passing through two points $(x_1, y_1)$ and $(x_2, y_2)$ is given by:

$y -y_1=m(x-x_1`)$ .....[1] where m is the slope of the line.

Calculate first the slope of the line:

Slope(m) = $\frac{y_2-y_1}{x_2-x_1}$

Substitute the given points;

$m = \frac{2-(-2)}{6-3}=\frac{2+2}{3} =\frac{4}{3}$

Substitute the value of m in [1] ;

$y - (-2) = \frac{4}{3}(x-3)$

$y+2=\frac{4}{3}(x-3)$ ......[1]

therefore, the equation of line in point slope form is, $y+2=\frac{4}{3}(x-3)$

(b)

to find the standard form of the equation [1]

Multiply both sides by 3 in [1] we get;

$3(y+2) = 4(x-3)$

using distributive property; $a\cdot (b+c) = a\cdot b + a\cdot c$

3y + 6 = 4x -12

Subtract 3y to both sides we get;

3y + 6 -3y = 4x - 12 - 3y

Simplify:

6 = 4x - 3y -12

Subtract 6 from both sides we get;

0 = 4x - 3y -12-6

Simplify:

4x - 3y - 18 =0

Therefore, the standard form of the equation is; 4x - 3y - 18 =0

If the estimate of expected population proportion having a desired characteristic based on intuition is 60 percent and the accep

Anika [276]

Answer:

Step-by-step explanation:

Our values are:

N = 100,000 (We assume it)

Proportion is p = 0.6

Margin of error (E) = 0.05

confidence-level (cl) = 0.95

Z-value = 1.96

We need to approach through Proportion,

$n=\frac{ (z_2 * p *q) + ME_2}{ME_2 + z_2 * p * q / N}$

Substituting,

$n = \frac{(1.962*0.6*0.4)+0.052}{0.052 + \frac{1.962 * 0.6 * 0.4}{100000}}$

$n= \frac{(3.841 * 0.24)+0.0025}{0.0025+\frac{3.841*0.24}{100000}}$

$n =\frac{ 0.9243}{0.002509}$

$n= 368$
