Answer:
idk
Step-by-step explanation:
Answer:
1:2
Step-by-step explanation:
convert kg to g
they both have a factor of 1100g
divide them both by 1100 to get 1:2
Answer:
Q1 = 61
Q3 = 63
Step-by-step explanation:
From the plot attached :
Data obtained is :
Temperature frequency
59 0
60 2
61 3
62 3
63 4
64 2
65 1
Frequency Total 15
Data in raw format :
60,60,61,61,61,62,62,62,63,63,63,63,64,64,65
The first quartile :
Q1 = 1/4(n+1)th term
n = 15
Q1 = 1/4(15+1)th term
Q1 = 1/4 * 16th
Q1 = 4th term
Q1 = 61
Third quartile (Q3):
Q3 = 3/4(n+1)th term
n = 15
Q3 = 3/4(15+1)th term
Q3 = 3/4 * 16th
Q3 = (48/4)th term
Q3 = 12th term
Q3 = 63
Okay, so it might be a little difficult to explain it but here we go:
You find the LCD (lowest common denominator) and multiply the top and bottom half of the fraction by the LCD:
(1/x) times xy (since it is divisible by both x and y)
then you do the same for the bottom (2/y) times xy
The x's on the top cancel out leaving you with 1/y
The y's on the bottom cancel out leaving you with 2/x
So now you multiple the top half (numerator) by the reciprocal of the denominator. In other words, multiply (1/y) by (x/2).
The answer is x/2y
I just answered a so let's start with b :
______________________________
b. The equivalent resistance of series
resistances is equal to their sum
Thus :
equivalent resistance = 480 + 360
equivalent resistance = 840
_______________________________
c.
I = V ÷ R
I = 120 ÷ 840
I = 0.1428 A
_______________________________
d. 0.1428 A
_______________________________
e. 480 ===》 120 - ( 480 × 0.1428 ) =
120 - 68.544 =
51.456
360 ===》 120 - ( 360 × 0.1428 ) =
120 - 51.408 =
68.592
_______________________________
f. 480 ===》68.544 lower than battery
360 ===》 51.408 lower than battery
