Answer:
18.75%
Step-by-step explanation:
The probability of the coin is 1/2, because it only has two options (tail or head).
Now, in the case of roulette, it has a total of 8 options, and the red region has 3 parts, that is, of the 8 options, roulette 3 is red, therefore the probability is 3/8
Now the final probability is the multiplication of the probability of both events:
(1/2) * (3/8) = 0.1875
s 18.75%
In other words, the probability of these two events happening, that the tail comes out and is red, i

Ab=750 and a=b-5, using this value of a in the original equation gives you:
(b-5)b=750
b^2-5b=750
b^2-5b-750=0
b^2-30b+25b-750=0
b(b-30)+25(b-30)=0
(b+25)(b-30)=0
b=30
SA = (2 x 3 x 10) + (2 x 3 x 12) + (12 x 10 x 2)
SA = 60 + 72 + 240
SA = 372
So, the surface area of the prism is 372 in².
Answer:
Step 1: 798/ 8= 99.75
Step 2: 99.75 * 41 = 4089.75
The first significant figure is the first non-zero digit in a number. Therefore the first significant figure in 4089.75 is 4.
If the number following the value that you are rounding to (in this case, the first significant figure ie 4) is greater than or equal to 5, round up the value, ie add 1 to the number. Otherwise round down to the nearest whole number.
Since the number following the significant digit, 4, is zero we therefore round down the number.
Resulting in:
4000.
Therefore, your answer is 4000
