Step-by-step explanation:

Answer: x = 2

Step-by-step explanation:

first, we remove the parentheses.

10 - 54 - 24x = 10x - 120 + 8

then, we just calculate that out.

-44 - 24x = 10x - 112

next, we move the terms.

-24x - 10x = -112 + 44

then, we collect the like terms and calculate it.

-34x = -68

finally, we divide both sides.

x = 2

Answer:

(c) n = 100, p = 0.2

Step-by-step explanation:

To approximate to use the normal distribution for a binomial, we need that:

[tex]np \geq 10, n(1-p)\geq 10[/tex]

So, for each option

(a) n = 10, p = 0.5

[tex]np = 10*0.5 = 5 < 10[/tex]

So not appropriate

(b) n = 40, p = 0.88

[tex]np = 40*0.88 = 35.2 > 10[/tex]

[tex]n(1-p) = 40*0.12 = 4.8 < 10[/tex]

So not appropriate.

(c) n = 100, p = 0.2

[tex]np = 100*0.2 = 20 > 10[/tex]

[tex]n(1-p) = 100*0.8 = 80 > 10[/tex]

So appropriate

(d) n = 100, p = 0.99

[tex]np = 100*0.99 = 99 > 10[/tex]

[tex]n(1-p) = 100*0.01 = 1 < 10[/tex]

So not appropriated

(e) n = 1000, p = 0.003

[tex]np = 1000*0.003 = 3 < 10[/tex]

So not appropriate

A Normal distribution to approximate probabilities for a binomial distribution with the given values of n = 100 and p = 0.2.

Given that,

Normal distribution to approximate probabilities for a binomial distribution with the given values of n and p.

We have to determine,

In which of the following situations would it be appropriate to use a normal distribution to approximate probabilities for a binomial distribution with the given values of n and p.

According to the question,

Probabilities for a binomial distribution with the given values of n and p.

(a) n = 10, p = 0.5

(b) n = 40, p = 0.88

(c) n = 100, p = 0.2

(d) n = 100, p = 0.99

(e) n = 1000, p = 0.003

To approximate to use the normal distribution for a binomial is given as,

[tex]np\geq 10 , \ n(1-p)\geq 10[/tex]

        [tex]= np \geq 10\\\\= 10 \times 0.5 = 5<10[/tex]

The normal distribution is less than 10 so, this not appropriate.

        [tex]= n.p \geq 10\\\\= (40).(0.88) \geq 10\\\\= 35.2\geq 10\\\\Then,\\=n(1-p) = 40(1-0.88) \geq 10 \\\\= 40\times 0.12 \geq 10 = 4.8\leq 10[/tex]

The normal distribution is less than 10 so, this not appropriate.

        [tex]= n.p \geq 10\\\\= (100).(0.2) \geq 10\\\\= 20\geq 10\\\\Then,\\=n(1-p) = 100(1-0.2) \geq 10 \\\\= 100\times 0.8\geq 10 = 80\geq 10[/tex]

The normal distribution is greater than 10 so, this appropriate.

        [tex]= n.p \geq 10\\\\= (100).(0.99) \geq 10\\\\= 99\geq 10\\\\Then,\\=n(1-p) = 100(1-0.99) \geq 10 \\\\= 100\times 0.01\geq 10 = 1\leq 10[/tex]

The normal distribution is less than 10 so, this not appropriate.

        [tex]= np \geq 10\\\\= 1000 \times 0.003 = 3<10[/tex]

The normal distribution is less than 10 so, this not appropriate.

Hence, A Normal distribution to approximate probabilities for a binomial distribution with the given values of n = 100 and p = 0.2.

Answer:

The value of d = -5

The polynomial function   x³ +5 x² - 4x -20 =0

Step-by-step explanation:

Explanation

Given that the equation is third degree polynomial

p(x) = x³ - d x² - 4x -20

Given factors x= 2 and x=-2

Substitute 'x' = 2 in given polynomial

     8 -d(2²)-4(2) - 20 =0

⇒   8 - 4 d - 8 -20=0

⇒     - 4 d-20 = 0

⇒    - 4 d = 20

⇒         d = - 5

The value of d = -5

Verification:-

After substitution d =-5 in given polynomial

x³ - (-5) x² - 4x -20 =0

put x=2

8 +5(4)-8-20 =0

             20 =20

The factors are x= 2 and x=-2 of the given polynomial

Answer:

Fred is 26 and Natalie is 12

Step-by-step explanation:

X= Fred's age

Y= Natalie's age

x+y=38

x+4y=74

Use the first equation and isolate the variable x to one side.

x+y=38

 -y= -y

x=38-y

Now use this equation and subsitute it into the second equation.

(38-y) + 4y = 74

Simplify to find y

38+3y=74

-38     =-38

3y=36

÷3   ÷3

y= 12

Now that we know y, input it into the second equation to find x.

x+12=38

  -12   -12

x= 26

Fred is 26 and Natalie is 12

To breakeven, the total cost of the company which is the sum of the fixed and variable cost will be equal to the total sales of the company such that the profit/loss is zero.

Let x be the number of screwdriver that must be produced  daily to break even

Then

68 + 1 * x = 2.5 * x

68 + x = 2.5x

collect like terms

68 = 2.5x - x

1.5x = 68

Divide both sides by 1.5

x = 68/1.5

= 45.33

This would be approximated to 46 screws

Multiply to get 25/16

The value of x is 5.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

ΔKLM ≈ ΔKQP

This means,

KL/KQ = KM/KP

(3x - 1) / 7 = 8/4

Cross multiply.

3x - 1 = 2 x 7

3x - 1 = 14

3x = 14 + 1

Divide both sides with 3.

3x = 15

x = 5

Thus,

x is 5.
