Answer:

5/14

Step-by-step explanation:

The total number of cards is 8

There are 5 blue cards

P(1st card is blue) = blue/total = 5/8

We take away a blue card

The total number of cards is 7

There are 4 blue cards

P(2nd card is blue) = blue/total = 4/7

The probability of blue blue is P(blue blue ) =

P(1st card is blue)*P(2nd card is blue) =

5/8* 4/7

20/56

We can divide the top and bottom by 4

5/14

Answer:

1/36

Step-by-step explanation:

When you roll a die the possible outcomes are 1,2,3,4,5,6

P(1) = number of outcomes that are 1 / total outcomes

       =1/6

The events are independent so we can multiply the probabilities

P(1,1) = 1/6*1/6 = 1/36

Which graph best represents the solution to 1/3x + 5= 5.5?
insens350 [35]

Answer:

Value of the unknown quantity for which from given equation we get true numerical equality is called root of that equation. Two equations are called equivalent when the multitudes of their roots match, the roots of the first equation are also roots of the second and vice versa. The following rules are valid:

1. If in given equation one expression is substituted with another identity one, we get equation equivalent to the given.

2. If in given equation some expression is transferred from one side to the other with contrary sign, we get equation equivalent to the given.

3. If we multiply or divide both sides of given equation with the same number, different from zero, we get equation equivalent to the given.

Equation of the kind ax+b=0, where a,b are given numbers is called simple equation in reference to the unknown quantity x.

The radius of a cylindrical water tank is 6.5 ft, and its height is 19 ft. What is the volume of the tank?
creativ13 [48]

Answer:

The volume of the cylinder is 2520.64ft³

Step-by-step explanation:

To calculate the volume of a cylinder we have to use the following formula:

v = volume

h = height = 19ft

π = 3.14

r = radius = 6.5ft

v = (π * r²) * h

we replace with the known values

v = (3.14 * (6.5ft )²) * 19ft

v = (3.14 * 42.25ft²) * 19ft

v = 132.665ft² * 19ft

v = 2520.64ft³

The volume of the cylinder is 2520.64ft³
