<h2>Answer:</h2>

The statement which is correct is:

B.     A and B cannot be both independent and mutually exclusive.

<h2>Step-by-step explanation:</h2>

Let we toss a coin single time.

and event A denote the tossing up a head.

and event B denote tossing a tail.

  • Now, we know that two events A and B are said to be mutually exclusive if:

                               P(A∩B)=0

  • and if two events A and B are independent then:

                         P(A∩B)=P(A)×P(B)

Here we have:

P(A)≠0 and P(B)≠0

So, if the events are independent then we have:

P(A∩B)≠0

Hence, the events can't be mutually exclusive.

Similarly if the two events are mutually exclusive then they can't be independent.

i.e. both mutually exclusive property and independent property can't exist at the same time if the two events have non-zero probability.

     Hence, the answer is: Option: B

Find the volume of the cement block in the figure shown.<br><br><br> Please help :)
Alexxandr [17]

9514 1404 393

Answer:

  1240 in³

Step-by-step explanation:

The overall dimensions of the block are ...

  10 in by 11 in by 17 in

The volume of that space is ...

  V = LWH = (10 in)(11 in)(17 in) = 1870 in³

The volume of each of the three identical holes is similarly found:

  V = (10 in)(3 in)(7 in) = 210 in³

Then the volume of the block is the overall volume less the volume of the three holes:

  = 1870 in³ - 3(210 in³) = 1240 in³

0.3(3a-4)-0.05(8a)(-7a)
Anit [1.1K]

Answer:

2.8a²+0.9a - 1.2

Step-by-step explanation:

Given the expression 0.3(3a-4)-0.05(8a)(-7a)

Expand using the distributive law

0.3(3a-4)-0.05(8a)(-7a)

0.3(3a)-0.3(4)-0.05(8a)(-7a)

0.9a-1.2 - 0.05(8a)(-7a)

0.9a - 1.2 + 2.8a²

Rearrange

2.8a²+0.9a - 1.2

Hence the required expression is 2.8a²+0.9a - 1.2

Find the surface area of a square pyramid with a base length of 24 cm and a height of 16 cm. Explain how you solved the problem.
icang [17]

Answer:

the answer b

Step-by-step explanation:

[surface area]=[area of 4 triangles sides]+[area of square base]

[area of square base]=24*24--------> 576 cm²

[area of one triangles side]

l=slant height

l²=16²+12²-------> l²=400-----------> l=20 cm

[area of one triangles side]=24*20/2--------> 240 cm²

[area of 4 triangles sides]=4*240----------> 960 cm²

[surface area]=[960]+[576]--------> 1536 cm²
