Answer:

6\ lb = 2.724\ kg

11\ kg = 24.2\ lb

Step-by-step explanation:

Given

1\ kg = 2.2\ lb

1\ lb = 0.454\ kg

Required

- Convert 6 lb to kg

- Convert 11kg to lb

To solve for (a), we make use of the second conversion unit:

1\ lb = 0.454\ kg

Multiply both sides by 6

6 * 1\ lb = 0.454\ kg * 6

6\ lb = 2.724\ kg

<em>Hence, a 6lb backpack weighs 2.724kg</em>

Solving (b): 11 kg to lb

Here, we make use of the first conversion unit

1\ kg = 2.2\ lb

Multiply both sides by 11

11 * 1\ kg = 2.2\ lb * 11

11\ kg = 24.2\ lb

<em>Hence, the cat weighs 24.2lb</em>

Setler [38]

Answer:

Step-by-step explanation:

To see if two events are independent you can use the formula P(a|b) = P(a)

In this problem P(C|Y) = 35/75 = .4667 and P(C) = 110/300 = 3.667,

therefore C and Y are not independent events because P(C∣Y) ≠ P(C).

The answer is choice D

PLEASE HURRY NEED TO TURN IN BY 8 PM SUPER EASY WILL GIVE BRAINLEIST
AlladinOne [14]

Answer:

answer: 5x + 10

Step-by-step explanation:

The distributive property (of which this is an example) demands that the 5 must multiply the x (which was done correctly) to give 5x

But the problem becomes undone when you forget about the 2. You must multiply the 2 by 5 as well to give 10.

The plus sign cannot be destroyed. The terms are not alike. So the answer is 5x + 10
