Answer:

(\frac{17}{18}, \frac{23}{6})

Step-by-step explanation:

D1 = \sqrt{(x+3)^2 + (y-4)^2}

D2 = \sqrt{x^2 + y^2}

Then set D1 = D2, and substitute in y = 3x+1

\sqrt{(x+3)^2 + (3x-3)^2} = \sqrt{x^2 + (3x+1)^2}

x^2 +6x +9 +9x^2 - 18x + 9 = x^2 + 9x^2 + 6x + 1

18x = 17

x = 17/18

Then to find y, substitute back in x for y = 3x + 1

y = \frac{17}{18} * 3 + 1

y = 23/6

Illusion [34]

Answer: a) 84 and b ) 2084

Step-by-step explanation:

Given : Sample standard deviation : s= $22.82

(Population standard deviation is unknown ) , so we use t-test.

Critical value or the​ 95% confidence intervals :t_{n-1}*=2.0

Formula to find the sample size :

n=(\dfrac{t^*\cdot s}{E})^2

a) E = 5

n=(\dfrac{(2)\cdot 22.82}{5})^2

n=(9.128)^2=83.320384\approx84

i.e. Required sample size : n= 84

b)  E = 1

n=(\dfrac{(2)\cdot 22.82}{1})^2

n=(45.64)^2=2083.0096\approx2084

i.e. Required sample size : n= 2084

line w passes through point (-6,-7) and has a slope 1/2. what is the equation for the line in point-slope form?
Elena L [17]

Answer:

y + 7 = \frac{1}{2} (x + 6)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

Here m = \frac{1}{2} and (a, b ) = (- 6, - 7 ) , then

y - (- 7) = \frac{1}{2} (x - (- 6) ) , that is

y + 7 = \frac{1}{2} (x + 6)
