The missing probability from the line in the diagram attached is 0.5.

<h3>What is a missing probability from the number line?</h3>

The number line is a graduated straight line system showing the value of each real number from (-∞, +∞).

The probability of a number line in the diagram below is halfway (middle) between the impossible event and a certain event.

Thus,

Probability from the line = 1/2

Probability from the line = 0.5 (decimal)

Suppose two dice (one red, one green) are rolled. Consider the following events. A: the red die shows 5; B: the numbers add to 2

labwork [276]

Answer:

Part 1

A = {5}

B = {(1,1)}

C = {(2,1), (2,3), (2,4), (2,5), (2,6), (1,2), (3,2), (4,2), (5,2), (6,2)}

D = {(1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (2,1), (2,2), (2,3), (2,4), (2,5), (3,1), (3,2), (3,3), (3,4), (3,6), (4,1), (4,2), (4,3), (4,5), (4,6), (5,1), (5,2), (5,4), (5,5), (5,6), (6,1), (6,3), (6,4), (6,5), (6,6)}

Part 2

Step-by-step explanation:

Part 1

We use brakets for indicate that the elements belong to a event.

In each event, the first member of each parentheses belong to dice red and the second belong to green dice.

We consider in each event all elements that accomplish the condition.

Part 2

When we combinate pair with the two dice obtain 36 pairs (6*6, six possible results in the red dice and six possible results in the green dice), now we look for all of them that do not add 2.

(1,2), (1,3), (1,4), (1,5), (1,6), (2,1), (2,2), (2,3), (2,4), (2,5), (2,6), (3,1), (3,2), (3,3), (3,4), (3,5), (3,6), (4,1), (4,2), (4,3), (4,4), (4,5), (4,6), (5,1), (5,2), (5,3), (5,4), (5,5), (5,6), (6,1), (6,2), (6,3), (6,4), (6,5), (6,6)

A machine can stamp 40 envelopes in 8 mins. How many of these machines working simultaneously are required or needed to stamp 12

kati45 [8]

Answer:

24 minutes

Step-by-step explanation:

let y be the 120 envelope per minutes.

40/8 = 120/y

40y= 8 x 120

40x =960

x = 960/40

= 24 minutes

An angle measures 67.8° more than the measure of a supplementary angle. what is the measure of each angle?

BARSIC [14]

X=the measure of first angle.
Supplementary angle of an angle x=180º-x (the measure of the second angle)

We solve this equation:

x+67.8=180-x
2x=180-67.8
2x=112.2
x=112.2/2
x=56.1

Supplementary angle of 56.1º=180º-56.1º=123.9º

answer: our angles would be 56.1º and 123.9º

Banneker Middle School has 750 students. Lynn surveys a random sample of 50 students and finds that 27 of them have pet dogs. Ho

Alika [10]

Answer: 405 students

Step-by-step explanation:

From the question, Banneker Middle School has 750 students and we are told that Lynn surveys a random sample of 50 students and finds that 27 have pet dogs. The number of students at the school that are likely to have pet dogs goes thus:

Since out of 50 students surveyed, 27 have pet dogs, this means we multiply the fraction by 750. This can be mathematically written as:

= 27/50 × 750

= 27 × 15

= 405

This means 405 students are expecting to have pet dogs.
