8. There are approximately 2.2046 kilograms in 1 pound. There are about 0.4536 pounds in 1 kilogram. To convert 112 lxs to kilog

Zanzabum

Answer:

Step-by-step explanation:

first of all the question is wrong 1 kilogram = 2.2046 pounds. and 1 pound = 0.4536kilogram.

if we want to convert 112lb into kilogram. we multiply it by 0.4536.

ie 112lb = 112x0.4536kg = 50.8032kg

to convert lb to kg you do this; lb x 0.4536

to convert kg to lb you do this; kg x 2.2046

Sets A and B are independent events and are mutually exclusive

Lynna [10]

The solutions are ${P}({A} \text { and }B})=0$ and $P}({A} \text { or } {B})=\frac{7}{12}$

Explanation:

Given that the sets A and B are independent events and are mutually exclusive events.

We need to determine the value of $P(A \text { and } B)$ and $P(A \text { or } B)$

<u>The value of </u> $P(A \text { and } B)$ <u>:</u>

Since, the sets A and B are mutually exclusive events, it is impossible for the two events to occur together.

Hence, we have,

${P}({A} \text { and }B})=0$

Thus, the value of $P(A \text { and } B)$ is 0.

<u>The value of </u> $P(A \text { or } B)$ <u>:</u>

For mutually exclusive events, the value of $P(A \text { or } B)$ is given by the formula,

$P(A \text { or } B)=P(A)+P(B)$

Substituting the values, we get,

$P(A \text { or } B)=\frac{1}{4}+\frac{1}{3}$

$P}({A} \text { or } {B})=\frac{7}{12}$

Hence, the value of $P(A \text { or } B)$ is $\frac{7}{12}$

Thus, the solutions are ${P}({A} \text { and }B})=0$ and $P}({A} \text { or } {B})=\frac{7}{12}$

7<br> 10 mm<br> 6 mm 7 mm<br> I need help to solve this

Svetach [21]

Solution:

<u>Note that:</u>

Surface area: 2(LB) + 2(BH) + 2(LH)

<u>Substitute the values given into the expression to find the surface area.</u>

2(7 x 10) + 2(6 x 6) + 2(6 x 10)
=> 2(70) + 2(36) + 2(60)
=> 140 + 72 + 120
=> 332 mm²

The surface area of the rectangular prism is 332 mm².
