Answer:
Step-by-step explanation:you take the biggest number on the graph and then you subtract the smallest number from it so if the biggest was 5, and the smallest was 3, you would do 5-3=2 and then 2 is your range

Answer:
A:
Multiple: 3 * 5 = 15
Add: 7 + the result of step No. 1 = 7 + 15 = 22
Divide: 4 / 2 = 2
Subtract: the result of step No. 2 - the result of step No. 3 = 22 - 2 = 20
Add: the result of step No. 4 + 3 = 20 + 3 = 23
B:
Add: 7 + 3 = 10
Multiple: the result of step No. 1 * 5 = 10 * 5 = 50
Divide: 4 / 2 = 2
Subtract: the result of step No. 2 - the result of step No. 3 = 50 - 2 = 48
Add: the result of step No. 4 + 3 = 48 + 3 = 51
Answer:
The number of students who scored more than 90 points is 750.
Step-by-step explanation:
Quartiles are statistical measures that the divide the data into four groups.
The first quartile (Q₁) indicates that 25% of the observation are less than or equal to Q₁.
The second quartile (Q₂) indicates that 50% of the observation are less than or equal to Q₂.
The third quartile (Q₃) indicates that 75% of the observation are less than or equal to Q₃.
It is provided that the first quartile is at 90 points.
That is, P (X ≤ 90) = 0.25.
The probability that a student scores more than 90 points is:
P (X > 90) = 1 - P (X ≤ 90)
= 1 - 0.25
= 0.75
The number of students who scored more than 90 points is: 1000 × 0.75 = 750.
