Since the range of the scores given was between 300 and 700 (which is 2 standard deviations below and above the mean), the probability that a randomly selected student's math score - as based on the empirical rule of statistics - is 95%. In decimal form, it is .95.
Answer:
-73, -34, 0.5, 1.2, 23
Step-by-step explanation:
In Mathematics, the set of numbers are arranged in two ways. It means that the numbers can be arranged either in ascending order or descending order. If the numbers are arranged from the least to the greatest, then it is called ascending order. In this form, the numbers are in increasing order. The first number should be lesser than the second number.
If the numbers are arranged from the greatest to the least, then it is called descending order. In this form, the numbers are in decreasing form. The first number should be greater than the second number.
Also, read: Descending Order
Standard Form
<em>The standard form to represent the least to the greatest arrangement </em>of numbers is given by:
a < b < c < d < …..
Here,
a, b, c, d represent the numbers
Example: 2 < 5 < 7 < 8
Answer:
29 minutes
Step-by-step explanation:
Given



Required
Determine the number of minutes (t) that he was on the trampoline.
This can be expressed as:

Where t represents the number of minutes
Substitute values for Total, Entrance Fee and Amount per minute


Solving further to get the value of t, we have:




Answer: y = 3x + 60
<u>Step-by-step explanation:</u>
Set up two equations and solve the system:
270 = 70x + b
- <u>(150 = 30x + b)</u>
120 = 40x
3 = x
Input "x" into one of the equations and solve for "b":
150 = 30x + b
150 = 30(3) + b
150 = 90 + b
60 = b
Equation: y = 3x + 60
This means that there is a flat fee of $60 plus a rate of $3 per student
Answer:
20%
Step-by-step explanation:2.8-3.5 then divide that by 3.5 and multiple the answer by 100 to get the percent
