Answer:

0.4018

Explanation:

Since all other outcomes are failures, the probability that a die rolled a number different of 5 is equal to:

5/6

Because there are 5 possibilities (1, 2, 3, 4, and 6) out of 6 total options.

Then, if the die is rolled five times, the probability of 0 successes is

P = 5/6 x 5/6 x 5/6 x 5/6 x 5/6

P = 0.4018

Therefore, the answer is 0.4018

8 times the sum of a number and 26 is less than 304.
Jlenok [28]

Answer:

x < 12

Step-by-step explanation:

So 8 times the sum of a number and 26 is less than 304. To find the number, lets write a equation where the "number" is x.
8 times the sum of a number and 26 can be written as 8 * x+26, however since the sum of x and 26 are being multiplied, we write this as 8(x+26). Since 8 times the sum of a number and 26 is less than 304, we set 8(x+26) to < 304. This gives us our equation:

8(x+26) < 304

Lets start to solve for x by dividing by 8, giving us:

x+26 < 38

Now lets isolate x by subtracting 26 from both sides, which gives us our answer:

x < 12

So x is less than 12.

Hope this helps!

Answer:

The area of the circular cross section of the pipe is 100\pi\ cm^{2}

Step-by-step explanation:

we know that

The area of the circle (cross section of the pipe) is equal to

A=\pi r^{2}

we have

r=20/2=10\ cm ----> the radius is half the diameter

substitute

A=\pi (10)^{2}

A=100\pi\ cm^{2}
