Answer:
Quartiles are the values that divide a list of numbers into quarters
Step-by-step explanation:
Step 1: Put the numbers in order: 2, 5, 6, 7, 10, 12 13, 14, 16, 22, 45, 65. Step 2: Count how many numbers there are in your set and then divide by 4 to cut the list of numbers into quarters. There are 12 numbers in this set, so you would have 3 numbers in each quartile. Interquartile Range: 8.5.
Hope this helps :)
Answer:
(Slope intercept form)
(Slope point form)
Step-by-step explanation:
The slope of the line can be calculated as following:
The the equation of the line in slope point form is:
Where (
,
) is a point of the line.
Then you must susbtitute the point given and the slope and you obtain:
The intercept form is:
Where b is the y-intercept.
Solve for y from the equation of the line in slope point form obtained above, then:

Answer:
x = -7
Step-by-step explanation:
Given:
5 – x = 12
Subtract 5 from both sides
5 – x - 5 = 12 - 5
- x = 7
Note: the coefficient of -x is -1
- x = 7
Divide both sides by the coefficient of -x
- x / -1 = 7 / -1
x = -7
Check
5 – x = 12
5 - (-7) = 12
5 + 7 = 12
It is possible to subtract a number from 5 and have more than 5 as your answer when the unknown number is a negative value
Answer:
8t - 15
Explanation:
⇒ 3(t+5)+5(t−6)
distribute inside parenthesis
⇒ 3(t) + 3(5) + 5(t) + 5(-6)
multiply the variables
⇒ 3t + 15 + 5t - 30
collect like terms
⇒ 3t + 5t + 15 - 30
add/ subtract like terms
⇒ 8t - 15
