If there are 4 bags of lettuce per whole box, 4 x 3 = 12
Then you must factor in the half of a box that can still contain lettuce, 4 ÷ 2 = 2
Which means that you would have 14 bags of lettuce total.
4 x 3 = 12
4 ÷ 2 = 2
12 + 2 = 14
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
• tanx = 
• sin²x + cos²x = 1 ⇒ sin²x = 1 - cos²x
Consider the left side
= 
- 
= 1 - cos²x
= sin²x = right side ⇒ verified
Answer:
k = 2
x = 2y
Step-by-step explanation:
If variables x and y vary directly, this is expressed as;
x ∝ y
x = ky
k is the proportionality constant
Let's assume the value of x and y since we are not given;
x = 20
y = 10
Substitute
20 = k(10)
10k = 20
k = 20/10
k = 2
Hence the constant of proportionality is 2
Substitute i=k = 2 into the equation x = ky
x = 2y
Hence an equation that relates x and y is x = 2y
<em>Note that the values here are assumed value, you can use the same method for any values of x and y</em>
Answer:

Step-by-step explanation:
Answer:
The standard deviation is 2.6832815729997
Step-by-step explanation:
SD^2=(12-12)^2+...+(14-12)^2/10
SD^2=72/10
SD^2=7.2
SD=squeare root of 7.2
SD=2.6832815729997
