PLEASE HELP!! I’LL GIVE BRAINLY

Mathematics

Being that the triangle has a center of dilation at (0,0) you must contract the points towards (0,0). The scale factor is 1/3 so you must divide the difference in location of the points on the X and Y axis by a scale of 1/3.

1/3 of 9 = 3 , y = 3

1/3 of -6 = -2 , x = -2

by changing these points a new triangle will be formed

An automatic car wash takes exactly 5 minutes to wash a car. On average, 10 cars per hour arrive at the car wash. Suppose that,
77julia77 [94]

Answer:

0.9595724

Step-by-step explanation:

Time taken to wash a car (μ) = 5 minutes

Hence, Number of cars washed per hour = 60/5 = 12 cars

If 5 cars arrive, 30 minutes to closing ; it takes 25 minutes to finish up ;

If 1 more car arrives, then it takes exactly 30 minutes

Hence, there will be no one in line at closing ;

IF 0 or 1 car arrives, if more than 1 car arrives, then there will be people in line at closing.

Hence, probability of waiting in line at closing :

1 - [p(0) + p(1)]

Using poisson :

P(x) = [(e^-μ) * (μ^x)] / x!

If x = 0

P(0) = [(e^-5) * (5^0)] / 0!

P(0) = (0.0067379 * 1) / 1

P(0) = 0.0067379

X = 1

P(1) = [(e^-5) * (5^1)] / 1!

P(0) = (0.0067379 * 5) / 1

P(0) = 0.0336897

Hence,

1 - (0.0067379 + 0.0336897)

1 - 0.0404276

= 0.9595724

Hence, the probability that anyone would be in the car washing line after closing is 0.9595724

Reduce to simplest form.<br> -5/8+(-8/5)=?
lara31 [8.8K]

Answer:

-2\frac{9}{40}

Step-by-step explanation:

-\frac{5}{8}+(-\frac{8}{5}) = -\frac{25}{40}-\frac{64}{40} (find common denominator)

=-\frac{89}{40}

=-2\frac{9}{40} (reduce to simplest form)

Hope this helps :)

(5,-5) and y = 3/2x +3Whats the equation of the line in slope intercept form
statuscvo [17]

Step-by-step explanation:

let (5,-5) =(x1,y1)

from eqn y=3/2x+3

slope (m)=3/2

now,

eqn in slope intercept form is;

(y-y1)=m (x-x1)

  • (y-5)=3/2 (x+5)
  • 2 (y-5)=3 (x+5)
  • 2y-10=3x+15
  • 3x-2y+25=0 is required eqn
