Answer:

0.262

Step-by-step explanation:

Edge 2021

The probability of getting 2 or more "Winner" caps on 4 bottles of water

is 0.2616.

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

The binomial probability is, [tex]^nC_xP^xq^{n - x}[/tex].

Let, p be the probability of winning,

Given,  1 out of every 4 bottles has the word "Winner".

Therefore, p = 1/4 and we know q = 1 - p = 3/4.

So, The probability of getting 2 or more "Winner" caps on 4 bottles of water

is P(X ≥ 2) which is, P(X = 2) + P(X = 3) + P(X = 4).

P(X ≥ 2) = [tex]^4C_2p^2q^2 + ^4C_3p^3q^1 + ^4C_4p^4q^0[/tex].

P(X ≥ 2) = 6(1/4)²×(3/4)² + 4(1/4)³×(3/4) + 1(1/4)⁴×1.

P(X ≥ 2) = 0.2109 + 0.0468 + 0.0039.

P(X ≥ 2) = 0.2616 or 26.16%.

Answer:

x+9

Step-by-step explanation:

4x³+12x²-72x

=4x(x²+3x-18)

=4x[x²+6x-3x-18]

=4x[x(x+6)-3(x+6)]

=4x(x+6)(x-3)

Answer:

The line on the graph below is my answer.

The graph of function y = -3x – 1 has been drawn below.

A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.

In order to plot the graph, we need to find out y's values corresponding to x's value

After that, we need to substitute the values of x's and y's into the coordinate geometry.

Given the line equation  y = -3x – 1

At x = 0 ⇒

y = -3(0) - 1

y = -1

So,

A(0,-1) is the first point on the line.

At y = 0 ⇒

0 = -3x – 1

x = -1/3

So,

B(-1/3,0) is the second point on the line.

Hence "The graph of function y = -3x – 1 has been drawn below".

Step-by-step explanation:

Answer:

The value of 2n - 2 is 4.

Step-by-step explanation:

Given the equation

[tex]n + 7 = 10[/tex]

Subtract  7 from both sides of the equation

[tex]n+7-7=10-7[/tex]

Simplify

[tex]n=3[/tex]

Now substituting n = 3 in the equation

2n - 2 = 2(3) - 2

          = 6 - 2

          = 4

Therefore, the value of 2n - 2 is 4.

Answer is x^2-2x-24

Step-by-step explanation:

Answer:

9y-3y=6y is equivalent to 9y – 3y.

Answer:

x=0.7x+24

We move all terms to the left:

x-(0.7x+24)=0

We get rid of parentheses

x-0.7x-24=0

We add all the numbers together, and all the variables

0.3x-24=0

We move all terms containing x to the left, all other terms to the right

0.3x=24

x=24/0.3

x=80

And that's how you get 80

Answer:

30

Step-by-step explanation:

Add all the measures 50+35+85+65+60= 210

subtract 180 from 210 and you get

210-180 = 30

we use 180 because  Example: Angles on one side of a straight line always add to 180 degrees. 30° + 150° = 180° When a line is split into 2 and we know one angle, we can always find the other one.

Answer:

x2+5x-3x-15=x2+2x-15

Step-by-step explanation:

(x)(x)=x2,(x)(5)=5x

(-3)(x)=-3x,(-3)(5)=-15

Answer: X^2 + 8x -15

Step-by-step explanation:

Use the foil method.

First, outer, inner, last

Multiply the first numbers inside each parenthesis. X*X = x^2

Next multiply the outer number in each parenthesis. X*5 = 5x

Then multiply the inner numbers of the parenthesis. -3*x= 3x

Finally multiply the last numbers in the parenthesis. -3*5 = -15

Now add all of these together

X^2 + 5x + 3x + -15

Combine like terms

X^2 + 8x -15

X can be solved from here, however it does not seem that you are asked to solve for x
