If a six-sided die is rolled 5 times, what is the probability of rolling numbers less than 3 ?
Distributions of probabilities help to model our world, allowing us to estimate the likelihood of a said event or to approximate the variability of incidence. It is a common way of describing the probability of an event as well as possibly forecasting it, and the further calculation can be defined as follows:
The possibility of rolling a six on a 6-sided die is [tex]\frac{1}{6}[/tex]. There are
Three 6's are therefore [tex]\binom{1}{6}^3[/tex] likely to roll.
The probability that you don't roll a 6 is [tex]\binom{5}{6}[/tex] and you are not 6 double the record is[tex]\binom{5}{6}^2[/tex].
In 5 tests, there are 10 different ways [tex]\binom{5}{3}=10[/tex] to rolle three 6s.
Then we all have together:
[tex]\to 10 \times \binom{1}{6}^3 \times \binom{5}{6}^2 \approx 0.0322[/tex]
Therefore, the final answer is "0.0322".

Solve 6b - 1 = 2/3b + 11 for b.
A) 5/18
B) 9/4.
C) 9/5
D) 4/9
9514 1404 393
Answer:
B) 9/4
Step-by-step explanation:
We can multiply by 3 to eliminate fractions, then solve the resulting 3-step equation in the usual way.
6b -1 = 2/3b +11
18b -3 = 2b +33 . . . . . . multiply by 3
16b -3 = 33 . . . . . . . . . . subtract 2b
16b = 36 . . . . . . . . . . . . add 3
b = 36/16 = 9/4 . . . . . . .divide by the coefficient of b
The solution is b = 9/4.

AnswerA,B,C
Step-by-step explanation:
A is right , using the exponet property, it turns into [tex]x^{1/5}[/tex] to the 7 power which equal x to the 1.4 th power. Using the product of power, [tex]x^{1/5}[/tex] to the 7th power is the same as 1/5 times 7 which equal 1.4. so b is right .Using the fractioal exponet rule C is also right as 5th root of x to the 7th power is the same as to the 7 power divided by 5 which 1.4 so c is right

Given a right triangle, find the length of the missing leg given the hypotenuse is 13 cm and the other leg is 5 cm. (Round to two decimal places.)
The length of the missing leg given the hypotenuse is 13 cm and the other leg is 5 cm would be 12 cm.
What is the Pythagoras theorem?The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.
a² + b² = c² (Pythagoras theorem)
where, c is the hypotenuse (longest length) of a triangle.
And a and b are the two other side of the triangle excluding the longest one.
Let x be the length of the missing leg of the given right triangle.
x² + 5² = 13²
x² = 13² - 5²
x² = 169 - 25
x² = 144
x = √144
x = 12
Hence, the length of the missing leg given the hypotenuse is 13 cm and the other leg is 5 cm would be 12 cm.

In an isosceles triangle the base angles are both 32 degrees, find the vertex
Answer:
116 deg
Step-by-step explanation:
note that an isoceles triangle always have 2 base angles that are equal.
Here we are already given one base angle of 32 deg. It follows that the other base angle must also be 32 deg.
We now have 2 angles of a triangle and we need to find the remaining one. Also recall that all 3 internal angles of a triangle sum to 180 deg. if we let the missing angle be x, then:
base angle + base angle + vertex angle = 180°
or,
32° + 32° + x° = 180°
64° + x = 180 deg
x = 180 - 64
x = 116 deg

Can anyone give me a hint or answer this?
Answer:
x=8.5
Step-by-step explanation:
∠AOC=68
∠COD= (2x+5)
∠AOC and ∠COD are complimentary angles. This means that when you add them together you get 90.
∠AOC + ∠COD = 90
68 + (2x+5) =90
2x+5=22
2x=17
x=8.5
