(-0.75X – 8) – (3.5X +5.4)

Answer:

x = 6

Step-by-step explanation:

Given

x + 5 = 11 ( isolate x by subtracting 5 from both sides )

x = 11 - 5 = 6

The probability that at least 1 number cube will show a number 8 or larger is 0.83.

In an experiment with two possible outcomes, the likelihood of exactly x successes on n repeated trials is known as the binomial probability (commonly called a binomial experiment). The binomial probability is

[tex]n^C_xp^xq^{n - x}.[/tex]

Given, In a certain board game, a 12-sided number cube showing numbers 1 to 12 is rolled.

So, Numbers that are 8 or larger is 8, 9, 10, 11, 12.

Now, The probability(p) of getting a number 8 or larger P(X ≥ 8) = 5/12.

hence q = 1 - p = 7/12.

Therefore, If 4 such cubes rolled the probability that at least 1 number cube will show a number 8 or larger is,

P(X≥ 8) = [tex]^4C_1(\frac{5}{12})(\frac{7}{12})^4+^4C_2(\frac{5}{12})^2(\frac{7}{12})^2+^4C_3(\frac{5}{12}^3)(\frac{7}{12})^1+^4C_4(\frac{5}{12})^4(\frac{7}{12})^0[/tex].

P(X≥ 8) = 4(0.41×0.115) + 6(0.173×0.34) + 4(0.072×0.58) + 1(0.030×1).

P(X≥ 8) = 0.283 + 0.35 + 0.167 + 0.030.

P(X≥ 8) = 0.83 or 83% chance.

Answer:

15+3n

Step-by-step explanation:

Answer:

[tex]a_{n} =15+3n[/tex]

Step-by-step explanation:

In this sequence, each term increases by 3, which means it is arithmetic with a common difference of 3. The explicit formula for an arithmetic sequence is [tex]a_{n}=a_{0} +dn[/tex], where [tex]a_{0}[/tex] is the zeroth term and d is the common difference. To find the answer simply plug in the values. The zeroth term is 15, we get this by going back one term before the sequence started, so subtracting 3 from 18. Then plugin 3 for d and you get your final answer.

Answer:

the answer is 6/25 , hope this helps

Answer:

6/25 is the correct answer. I guess it helps you

Step-by-step explanation:

sin2x - sinx = 0

2sinxcosx - sinx = 0

(Double Angle Formula)

sinx(2cosx - 1) = 0

Either sinx = 0 or cosx = 1/2.

When sinx = 0,

x = 0 or x = π.

When cosx = 1/2,

x = π/3 or x = 5π/3.

Hence the solutions are

x = 0, x = π/3, x = π or x = 5π/3.

Answer:

6.3

Step-by-step explanation:

8.5 - (-4.8)

Let's focus on - (-4.8)

if a negative number is subtracted, it reverses itself

In other words, if a negative number is being subtracted, it is the same as being added as a positive number

So we change the equation to

8.5 + 4.8 = 13.3

Now we subtract 7 from 13.3

Since positive 7 is being subtracted, the rule for -4.8 does not apply to it

13.3 - 7 = 6.3
