I know this isn’t an answer but if you put a picture of the notes I can do this
Answer:
1200 Square Feet
Step-by-step explanation:
if he walks 40ft then turns 90* then walks 30ft. You take the 40ft along one side and mutiply it by the 30ft that he walks so you can get the area.
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
Answer:
Step-by-step explanation:
the first method :
s(x) = 2 - x and f(x) = 3x
(s f) (-7) = s(-7) ×f(-7)
but : s(-7) = 2 - (-7) =2+7 = 9
f(-7) = 3(-7) = - 21
so : (s f) (-7) = (9)×(-21) = - 189
the second method :
calculate : (s f) (x) == s(x)×f(x) = (2-x) 3x = 6x - 3x²
(s f) (-7) = 6(-7) -3 (-7)² = - 42 -147 = -189
Answer:
D. 48 square meters
Step-by-step explanation:
The rectangular mirror measures 6 meters by 8 meters.
To find the amount of space the mirror will cover, we simply need to find the area of the mirror.
The area of a rectangle is:
A = L * B
where L = length
B = breadth
Therefore, the area of the mirror is:
A = 6 * 8 = 48 square meters
The mirror will cover an area of 48 square meters.
