How to solve 72 + x+x + 52+80°

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:

4) 2/6 or 1/3

5) 42/110 or 21/55

Step-by-step explanation:

4) there are two red options out of a total of 6 options, so 2/6

5) 7 red out of total of 11, so 7/11 · 6/10 = 42/110

To get the fraction 6/10:

we reduce 7 to 6 because there is one less red than originally

we reduce 11 to 10 because there is one less from the initial total

Answer:

AB = 54

Step-by-step explanation:

DE is a midsegment of the triangle and is half of AB , that is

2x + 13 = [tex]\frac{1}{2}[/tex](13x - 37) ← multiply through by 2 to clear the fraction

4x + 26 = 13x - 37 ( subtract 13x from both sides )

- 9x + 26 = - 37 ( subtract 26 from both sides )

- 9x = - 63 ( divide both sides by - 9 )

x = 7

Thus

AB = 13x - 37 = 13(7) - 37 = 91 - 37 = 54

Answer:

Step-by-step explanation:

Y = k1/x

4 = k 1/2.5

2.5 x 4 = k

10 = k

Now using this equation we will find the other answers

A) find y when x = 20

Y = k 1/x

Putting values

= 10(1/20) = 1/2 = 0.5

B) find x when y = 5

Y = k 1/x

Putting values

5 = 10 1/x

5x = 10

x = 10/5 = 2

The answer is D. 110

Step-by-step explanation:

You add 8 and 3 and get 11 first because in parentheses, and then you subtract that by 14, which will give you 3. Then you multiply 3 times 5 to get 15 and add that to 95 to get your answer. Hope this helps!

Step-by-step explanation:

Answer: The numbers are 1 and 3.

Step-by-step explanation:

Let x = smaller number , y= larger number.

As per given,

[tex]x=\dfrac{y}{3}[/tex]   ...(i)

[tex]x+y=y^2-5[/tex]       ...(ii)

Put value of x from (i) in (ii)

[tex]\dfrac{y}{3}+y=y^2-5\\\\\Rightarrow\ \dfrac43y=y^2-5\\\\\Rightarrow\ 3y^2-4y-15=0\\\\\Rightarrow\ 3y^2-9y+5y-15=0\\\\\Rightarrow\ 3y(y-3)+5(y-3)=0\\\\\Rightarrow\ (y-3)(3y+5)=0\\\\\Rightarrow\ y=3 \ \ or\ y=\dfrac{-5}{3}[/tex]

Since numbers are positive , so y=3 is correct.

And x will be 1  [from (i)]

Hence, the numbers are 1 and 3.

Answer: 18 feet

Step-by-step explanation:

Well, first we need to find the circumference because that is the outside of the pipe.

Circumference = 2 x Pi x Radius

Radius is half of diameter.

So we plug in all the values in to the formula.

2 x Pi x 6 inches = Circumference

12Pi = 37.69911184 inches

37 inches to feet = about 3 feet.

3 x 6 = 18 feet.

The volume of the cube is 1 cubic foot.

Given that, each side of cube is 1 inch.

When dilation of the cubic inch by a factor of 12. Then each side of cube became 12 inches.

As we know that,

            [tex]12inch=1 foot[/tex]

So that, each side of cube become 1 foot.

   Volume of cube [tex]=(side)^{3}[/tex]

               [tex]Volume=1^{3}=1ft^{3}[/tex]

The division allows us to divide or 'share' numbers to find the answer to a problem.

For example, to evenly share 10 sweets between 5 kids, we use division to find 10/5 = 2 sweets per kid.

It's given a high school football stadium has 3,892 seats distributed in 14 sections and each section has the same number of seats.

To find the number of seats in each section we use division:

3,892 seats / 14 sections = 278 seats per section

Answer:

s = 2r + 1

Step-by-step explanation:

Number of sunflower (s) is 1 more than twice the number of roses (r)

Mathematically ;

Number of sunflower = 1 + 2 * number of roses

Sunflower = s ; roses = r

s = 2r + 1

We want to study the relation between the number of sunflowers and roses, we will see that it is an equation and the equation is:

s = 2*r + 1

So we know that the number of sunflowers is one more than twice the number of roses, notice that it represents an equation (so it is not an inequality)

And the equation can be written as:

s = 2*r + 1

The number of sunflowers is 2 times the number of roses, plus 1.

Answer:

x= -2

Step-by-step explanation:

Let's solve your equation step-by-step.

15−10x=5(x+9)

Step 1: Simplify both sides of the equation.

15−10x=5(x+9)

15+−10x=(5)(x)+(5)(9)(Distribute)

15+−10x=5x+45

−10x+15=5x+45

Step 2: Subtract 5x from both sides.

−10x+15−5x=5x+45−5x

−15x+15=45

Step 3: Subtract 15 from both sides.

−15x+15−15=45−15

−15x=30

Step 4: Divide both sides by -15.

−15x/-15 = 30/ -15  

x= −2
