When rolling a die (1) what's the probability of getting an even number in two successive throws??​

Mathematics

Answer:

when rolling a die you can end up getting 6 possibilities all together.

the number of even numbers in a die is 3.

therefore in the first throw you have a possibility of getting an even number at 0.5 or 50%.

and in the second throw you have a possibility of getting an even number at 0.5 x 0.5 which is 0.25 or 25%.

Hope this helps.

Pyramid A is a square pyramid with a base side length of 14 inches and a height of 6 inches. Pyramid B has a volume of 3,136 cub
mash [69]

Answer:

12.5%    Step 1  to find volume of Pyramid A  Step 2 is find percentage through division then multiplication of 100  

Step-by-step explanation:   Length of one side of the base (a) = 14 in

Height of square pyramid (h) = 6 in

Using the square pyramid volume formula,

Volume = 1/3 x a^2 x h

Volume = 1/3 x 14^2 x 6

Volume = 392 in3

The volume Pyramid A is 392 cubic inches.

Pyramid A has a volume = 392 cubic units     Pyramid B has a volume of 3,136 cubic inches.    to find percentage 392 of 3136 we divide then * 100   To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator...  = (392/3136 ) x 100% = 12.5%   Proof is  (12.5 * 3136 ) / 100 = 392

If the first differences of a sequence are a constant -7 and the third term is 22, find the first 5 terms of the sequence.
Andru [333]

Answer:

36, 29, 22, 15, 8

Step-by-step explanation:

Step 1: State known information

First difference is -7

Third term of the sequence is 22

Step 2: Find first 5 terms

You just need to add and subtract 7 to 22 and the answer 5 times

1. 36 +7

2. 29 +7

3. 22 <- We know 22 is the 3rd term

4. 15 -7

5. 8 -7

Therefore the first 5 terms of the sequence is 36, 29, 22, 15, 8

8u/u^2-18u+81 subtract 72/u^2-18u+81
Karo-lina-s [1.5K]
Your question is:
\frac{8u}{u^2-18u+81} -\frac{72}{u^2-18u+81}
Then, the above formula equate:

\frac{8u-72}{u^2-18u+81}
Factor out 8 from the numerator we get:
\frac{u-9}{u^2-18u+81}
Factorization of the denominator:
\frac{u-9}{(u-9)^2}
Simplifying the numerator and the denominator by (u-9) we get:
\frac{1}{(u-9)}
