Answer:
15
Step-by-step explanation:
Rate of change or slope or gradient of a line passes two points (x1, y1) and (x2, y2) could be calculated by:
(y2 - y1)/(x2 - x1)
=> Rate of change of the line passing (1,15) and (3,45):
(45 - 15)/(3 - 1) = 30/2 = 15
Answer:
Incorrect
Step-by-step explanation:
This interpretation is incorrect because it states that 98% of the data is with in the confidence interval.
or 98% of the laptop have screen size between 19.2 and 21.4 inches
However, the interpretation would have been correct if it would have stated as - Value of the population mean i.e mean size of the laptop screen lies within the confidence interval.
Answer:
Perimeter of the rectangle = 96 meters.
Step-by-step explanation:
Let the width of the rectangle = K
So, the length of the rectangle = 5K
Area = 320 sq meters
Now, Area of a Rectangle = Length x Width
⇒ 320 = K x 5K
or,
So, the vlue of K = 8 or, K = -8
But as K represents a length hence, K ≠ -8
So, the <u>width of the rectangle = 8 meters</u>
and the<u> length of the rectangle = 8 x 5 = 40 meters</u>
Now, Perimeter = 2(length + width)
= 2(8 + 40) = 96 meters.
So, the perimeter of the rectangle = 96 meters.

Answer:
Each bag will get 5 candy canes and 3 cookies.
Step-by-step explanation:
Find the divisors of both numbers
75 = 1,75 : 3,25 : 5,15 : 15,5 : 25,3 : 75,1
45 = 1,45 : 3,15 : 5,9 : 9,5 : 15,3 : 45,1
Since the largest common divisor is 15, we want to use 15.
Each bag will get 5 candy canes and 3 cookies.
