Answer:
There are 23.1% probability of flights getting delayed.
Step-by-step explanation:
Given:
Number of samples of flights selected = 1000
Number of flights arrived on time = 769
We need to find the probability of flight being delayed.
Solution:
Now we will first find the number of flights which are delayed.
number of flights which are delayed can be calculated by subtracting Number of flights arrived on time from Number of samples of flights selected.
framing in equation form we get;
number of flights which are delayed = 
Now we will find the probability of flight being delayed.
probability of flight being delayed can be calculated by dividing number of flights which are delayed from the Number of samples of flights selected and then multiply by 100.
framing in equation form we get;
probability of flight being delayed = 
Hence There are 23.1% probability of flights getting delayed.
Answer:
Answer:y = 1/4x -8Step-by-step explanation:First find the slope of the linex-4y =3Subtract x from each sidex-4y -x = -x+3-4y = -x+3Divide each side by -4-4y/-4 = -x/-4 +3/-4y = 1/4 x -3/4This is in the form y= mx+b where the slope is m and the y intercept is bThe slope is 1/4We want the same slopey = 1/4x +bwe know the y intercept is -8y = 1/4x -8.
Step-by-step explanation:
Answer:
3. 10 - 5 is 5. so that is the difference. difference means subtraction.
4. 108 - 30 = 78. so she can move 78 degrees miore after therapy because 108 minues 30 is 78
5. 99 because 180 - 81 = 99. there is always 180 degrees in a line angle.
6. 130 degrees. 25 + 25 = 50 so 180 minus 50 equals 130

Answer:
The probability that a student is proficient in mathematics, but not in reading is, 0.10.
The probability that a student is proficient in reading, but not in mathematics is, 0.17
Step-by-step explanation:
Let's define the events:
L: The student is proficient in reading
M: The student is proficient in math
The probabilities are given by:
The probability that a student is proficient in mathematics, but not in reading is, 0.10.
The probability that a student is proficient in reading, but not in mathematics is, 0.17
You will need 50 because 10 divided by 500 is 50 so you will need 50 markers.<span />
