Answer:

(a) The travel times of the Los Angeles workers have a higher variability than those of the New York City area and about 54 out the 70 Los Angeles workers take longer (over 20minutes) than the maximum travelling time for the New York City workers (18 minutes) when they travel to work

(B) (i) The percentage of workers that travel close to the maximum travel times given in the data of the two cities

(ii) Almost half of the New York City area workers spend between 40 and 100 minutes to work, while almost half (32) of the Los Angeles workers spend between 0 and 20 minutes to work every day

Step-by-step explanation:

The travel times for the 70 Los Angeles workers are;

Number of workers                    {}         Travel time

32                    {}                                      0 - 20 minutes

22                    {}                                      20 - 40 minutes

10                   {}                                        40 - 60 minutes

4                   {}                                          60 - 80 minutes

2                   {}                                          80 - 100 minutes

The travel times for the 61 New York City area workers are;

18                   {}                                          0 - 20 minutes

14                   {}                                          20 - 40 minutes

10                   {}                                          40 - 60 minutes

12                   {}                                          60 - 80 minutes

7                    {}                                           80 - 100 minutes

-3x-5y=9<br> 5x + 5y=-15
cestrela7 [59]

Hello from MrBillDoesMath!

Answer:

x = -3, y = 0

Discussion:

5x + 5y = -15  =>

x + y = -3        =>           (divide both sides by 5)

x + y - y = -3 -y    =>      (subtract y from both sides)

x = -3 - y  

Substitute x = -3 - y   into the top equation:

-3x - 5y = -9 =>

-3(-3-y) - 5y = 9  =>          ( substitute -3 -y for x)    

(-3)(-3) + (-3)(-y) - 5y  = 9 =>

9    + 3y - 5y = 9            =>      (  -*-   is a + number)

9 -2y = 9      =>

9 - 9 -2y  = 9 - 9     =>      (subtract 9 from both sides)

-2y = 0            =>

y = 0

Since x = -3 -y, x = -3 - 0 = =3


Regards,  

MrB

P.S.  I'll be on vacation from Friday, Dec 22 to Jan 2, 2019. Have a Great New Year!

Given the equation, what is the center and radius of the circle? <br> (X-2) ^2+ (Y+11)^2=100
LekaFEV [45]

Answer:

Center: (2, -11)

Radius: 10

Step-by-step explanation:

(x - 2)² + (y + 11)² = 100

(x - h)² + (y - k)² = r²

-------------------------------

x - 2 = 0

  +2   +2

x = 2

------------

y + 11 = 0

   -11    -11

y = -11

------------------------------

r² = 100

r = √100

r = 10

----------------------------

Center: (h, k)

Radius: r

-------------------------------

Center: (2, -11)

Radius: 10

I hope this helps!
