Find the value of X 150 4X-5

A = 12, b = ?, c = 15 a = ?, b = 7, c = 25 a = 8, b = 15, c = ? a = 24, b = ?, c = 26

Inga [223]

1: b=9
2: a= 24
3: c=17
4: b=10

Use a^2 + b^2 = c^2 to answer.
1: 12^2 (144) + b = 15^2 (225)
225-144 = 81
Square root 81 = 9
2: a + 49 = 625
625-49=576
Square root 576 = 24
3: 64 + 225 = 289
Square root 289 = 17
4: 576 + b = 676
676-576 = 100
Square root 100 = 10

The outcome of the first event does affect the outcome of the second, so that the probability is changed

Sedbober [7]

Answer:

Dependent Events

Step-by-step explanation:

Suppose we have 3 balls 1,2,3 and we have to find the probability of choosing one ball.

If the first ball is chosen the probability will 1/3 leaving behind 2 balls in the bag. If the first ball is not replaced and we have to choose again the probability of choosing the second or third ball would be 1/2 which is changed from the original probability of choosing 1 ball out of 3. In this the outcome of the first event does affect the outcome of the second, so that the probability is changed. This is when choosing is done without replacement.

In this the events are called dependent events.

Consider this scenario again and suppose we replace the first ball after it is chosen back into the bag. Then again we choose another ball . And the probability of choosing the second ball after replacement remains the same as choosing the first ball. In this he outcome of the first event does not affect the outcome of the second, so that the probability remain the same. This is done by replacement.In this the events are independent.

Which undefined geometric term is described as an infinite set of points that has length but not width?

Ivahew [28]

The correct answer is line.

Explanation:
A line contains an infinite number of points, but since each point has no width or length to speak of, there is no width to a line. Additionally, it has infinite length since there is an infinite number of points included in it.

The perimeter of a rectangle is 44 m. The length is 4 m more than the twice the

mojhsa [17]

Step-by-step explanation:

perimeter is given by

p=2L +2W

but from the expression;The length is 4 m more than the twice the width

is written as L =4+2W

putting it in the formula

p= 2(4+2W) +2W

but perimeter was given as 44m

44= 8+4w+2w

44=8+6w

44-8=6w

36=6w

dividing through by 6

w=36/6

w=6m

thus, the width is 6m

put it in the expression L =4+2W to get the length

L =4+2(6)

L=4+12

L=16m

thus the length is 16m
