Answer:
5
Step-by-step explanation:
If you multiply the square root of any number by the square root of the same number you get that number.
Answer:
Step-by-step explanation:
Do you mean multiply?
- 8/15 * 20/24
- 8/15 * 5/6
5 and 15 have a common divisor -- 5
- 8/3 * 1 / 6
8 and 6 can be divided by 2.
-4/3 * 1/3
-4 / 9
====================
You could do the same thing without cancellation.
-8/15 * 20/24 = -160 / 360
Now you can divide by common factors. Start by dividing top and bottom by 10
- 16 / 36 Now divide top and bottom by 4
- 4 / 9
Answer:
-6
Step-by-step explanation:
The equation is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The y intercept is the value when x = 0
The y value is -6 when the x value is 0
y = -4x+ (-6)
Center : Mean Before the introduction of the new course, center = average(121,134,106,93,149,130,119,128) = 122.5 After the introduction of the new course, center = average(121,134,106,93,149,130,119,128,45) = 113.9 The center has moved to the left (if plotted in a graph) because of the low intake for the new course. Spread before introduction of the new course : Arrange the numbers in ascending order: (93, 106,119, 121), (128, 130,134, 149) Q1=median(93,106,119,121) = 112.5 Q3=median(128,130,134,149) = 132 Spread = Interquartile range = Q3-Q1 = 19.5 After addition of the new course,
(45,93, 106,119,) 121, (128, 130,134, 149)
Q1=median(45,93,106,119)=99.5
Q3=median (128, 130,134, 149)= 132
Spread = Interquartile range = 132-99.5 =32.5
We see that the spread has increased after the addition of the new course.
