I would go with A but I am not 100% sure so you may want to check however you can.
Mean = 60 / 4 = 15
13 - 15 = -2
17 - 15 = 2
9 - 15 = -6
21 - 15 = 6
Total of squares = 4 + 4 + 36 + 36 = 80
because this is a sample we divide this by n - 1 ( = 3)
Standard deviation = sqrt (80/3) = 5.16 answer
Answer:
Option (C)
Step-by-step explanation:
Value of y is more than the product of x and 2.
Equation representing the given condition will be,
y = 2x + 1
Therefore, by substituting the values of x in the equation we can get the table for the input - output values for the equation,
x 0 1 2 3 4
y 1 3 5 7 9
Therefore, table given in the Option (C) will be the correct option.
If we let x as candy A
y as candy B
a as dark chocolate in candy a
b as dark chocolate in candy b
c as caramel
d as walnut
P as profit
we have the equations:
a + c = x
2b + d = y
a + 2b ≤ 360
c ≤ 430
d ≤ 210
P = 285x + 260y
This is an optimization problem which involves linear programming. It can be solved by graphical method or by algebraic solution.
P = 285(a + c) + 260(2b +d)
If we assume a = b
Then a = 120, 2b = 240
P = 285(120 + 120) + 260(240 + 120)
P = 162000
candy A should be = 240
candy B should be = 360
A+7
4+7
4+7=11
b-3
5-3
5-3=2
9c
9(10)
9(10)=90
