HELP DUE IN 15 MINS! x = ??

Mathematics
1 answer:
bija089 [108]3 years ago
6 0

Answer:

Step-by-step explanation:

This arc has the same measurement as the central angle. The central angle is LON where O is the center of the circle.

Point M forms an angle that is 1/2 the central angle when M is on the circumference and opposite the 150o angle. Therefore M is the vertex of a 75 degree angle.

76x - 1 = 75       Add 1 to both sides.

76x = 76            Divide by 76

x = 1

yaroslaw [1]

Answer:

0.74

Step-by-step explanation:

A <u>tree diagram</u> is a visual way of showing combinations of <u>two or more events</u>. The outcome of each branch is labelled at the end of the branch line and its probability is written alongside the branch.

To calculate the probabilities of each combination, follow the branches and <u>multiply the probabilities</u> together.

There are two possible combinations to get a final outcome of D:

  • A and D = 0.6 × 0.7 = 0.42
  • B and D = 0.4 × 0.8 = 0.32

Therefore, the probability of D is:

⇒ P(D) = P(A and D) <u>OR</u> P(B and D):

⇒ P(D) = 0.42 + 0.32

⇒ P(D) = 0.74

Answer:

x = 1/10

Step-by-step explanation:

2/x -2 = 3/2x +3

Add 2 to each side

2/x -2+2 = 3/2x +3+2

2/x = 3 /2x  +5

Subtract 3/2x from each side

2/x  -3/2x = 3 /2x - 3/2x  +5

2/x  - 3/2x = 5

Get a common denominator

2/x *2/2  -3/2x =5

4/2x  - 3/2x = 5

1/2x =5

Multiply each side by 2x

1 /2x * 2x = 5 *2x

1 = 10x

Divide each side by 10

1/10 = 10x/10

1/10 =x
