Answer:

-4r - 11 = 4r + 21

-4r -4r = 21 + 11

-8 = 32 (Divide both sides by -8)

in a recent year in the united state, 83, 600 passengers car rolled over when they crashed, and 5,127,400 passengers cars did no
alexdok [17]

Answer:

0.01 probability of a car rolling over in a crash.

It is very unlikely for a car to roll over in a crash.

Step-by-step explanation:

Let E be any event.

Then, the probability of happening of an event E = \frac{\textrm{Number of favorable outcomes}}{\textrm{Total Outcomes}}

Now here,

Let E1 = The event where cars rolled when they crashed

E2 =  The event where cars did not roll when they crashed

The number of cars that did roll = 83, 600

The number of cars that did not roll = 5,127,400

So, total  number of cars taken into account for any event

= 83, 600  + 5,127,400 = 5,211,000

So, P(E1)  = 83, 600 / 5,211,000 = 0.01

Hence there is 0.01 probability of a car rolling over in a crash.

and P(E2)  = 5,127,400  / 5,211,000 = 0.98

Since P(E2) is way way more than that of P(E1)

Hence, it is very unlikely for a car to roll over in a crash.

Plz help me with 17 part a and b I will thank u
podryga [215]
Part A

There are 2 cups in a pint, so 2 x 3 = 6
Plus 5 cups,
1 quart is equal to 1/4 of a gallon, and there are 4 cups in a gallon,
and another quart is 4 more cups,
so add all of the cups together:
6 + 5 + 4 + 4 = 19

Kelly is incorrect, because I added all of the cups together and I got 19. 

Part B

Since 4 cups fit in a quart, and she has 4 quarts, her quarts only hold 16 cups, which isn't enough, because there are 19 cups.

Hope this helped! If you have anymore questions or don't understand, please comment or DM me. :)

40 Points Please Help I'm not sure if they are correct.

Replace the x and y values in the given equation.

1. d = √((6-0)^2 + (8-0)^2

= √(6^2 + 8^2)

= √(36 + 64)

= √100

= 10

2. d = √((3-(-3))^2 + (5-2)^2

=√((3+3)^2 + 3^2)

=√(6^2 + 3^2)

= √(36 + 9)

= √45

=3√5 ( exact ) or as a decimal 6.7082 (round as needed)

3.  d = √((4-(-1))^2 + (-5-(-1))^2

= √((4+1)^2 + (-5+1)^2)

= √(5^2 + -4^2)

=√(25 + 16)

= √41 (exact) or as a decimal 6.4031 (round as needed)
