If P(A)=0.54 then what value of P(B) the event A and B are complementary event

aleksley [76]

Answer:

P(B) = 0.46

Step-by-step explanation:

Probability

The complementary event of a given event A is defined as "not A" or the event that A does not occur.

For example, if A is defined as 'getting a job', then the complement of A is 'not getting a job'.

Event A and its complementary event (call it B) must satisfy:

P(A) + P(B) = 1

If we know P(A)=0.54, then

P(B) = 1 - P(A)

P(B) = 1 - 0.54

P(B) = 0.46

Savannah and Sarah are planning on riding their bikes to a point located at 1100 ft from their house their bicycle tires have a

Molodets [167]

Answer:

323.2 revolutions (324 revolutions (rounded) )

Step-by-step explanation:

Savannah has to cover 1100 feet

Sarah has to cover 1100 feet

Now,

For Savannah:

diameter is 26 in, so radius will be 26/2 = 13 inches

Circumference (1 rev) = $2 \pi r = 2 \pi (13) = 81.68$

There are 12 inches in 1 feet, so distance to be covered in inches:

1100 * 12 = 13,200 inches

Number of revolutions = 13,200/81.68 = 161.6 revolutions

For Sarah, it is the same so:

161.6 revolutions

Together:

161.6 + 161.6 = 323.2 revolutions to cover the whole distance (both)

Rounded, it is About 324 revolutions
