8 0

Answer:

Step-by-step explanation:

Given

Probability of finding oil at site 1 is 0.30

Probability of finding oil at site 2 is 0.15

Probability of finding oil at site 3 is 0.20

Probability of Finding oil at all three sites

i.e. oil is present in all three sites simultaneously

=0.3\times 0.15\times 0.20=0.009

Probability of not finding oil at any of these sites=(1-0.3)\cdot (1-0.15)\cdot (1-0.2)=0.476

Complement of Finding oil at all three sites is equivalent to not finding the oil at all three sites

i.e. A'\cap B'\cap C'

Complement of not finding oil at any of the sites is equivalent to probability of finding oil at any of the given sites

A\cup B' \cup C' or

'\cup B \cup C' or

A'\cup B' \cup C

What is the simplified value of the exponential expression 16 Superscript one-fourth?
pochemuha

<u>Answer: </u>

The value of the exponential expression 16^{\frac{1}{4}} is 2  

<u>Solution:</u>

16 superscript one-fourth= 16^{\frac{1}{4}}

As per the problem,  

We have to find the value of 16^{\frac{1}{4}}  

16 in terms of 2 can be written as 2\times2\times2\times2

= (2 \times 2 \times 2 \times 2)^{\frac{1}{4}}

=\left(2^{4}\right)^{\frac{1}{4}}

As per the exponential rule, a^{(m)^{n}}=a^{m \times n}

=2^{4 \times \frac{1}{4}}

Here, 4\times\frac{1}{4}=1

= 2^{1}

= 2

Hence, the value is 2.

If you have a cube measuring 1 unit on each side, how many of those cubes would fit into a space 2 units by 3 units by 4 units
alisha [4.7K]

Given:

Measure of a cube = 1 unit on each side.

Dimensions of a space 2 units by 3 units by 4 units.

To find:

Number of cubes that can be fit into the given space.

Solution:

The volume of cube is:

V_1=a^3

Where, a is the side length of cube.

V_1=(1)^3

V_1=1

So, the volume of the cube is 1 cubic units.

The volume of the cuboid is:

V_2=l\times b\times h

Where, l is length, w is width and h is height.

Putting l=2,b=3,h=4, we get

V_2=2\times 3\times 4

V_2=24

So, the volume of the space is 24 cubic units.

We need to divide the volume of the space by the volume of the cube to find the number of cubes that can be fit into the given space.

n=\dfrac{V_2}{V_1}

n=\dfrac{24}{1}

n=24

Therefore, 24 cubes can be fit into the given space.
