D. All ten selected gamers are the same age.

Answers

Answer 1

Answer:

For this to be a binomial experiment, the assumption that is made is:

C. The probability of being selected is the same for all ten gamers.

Step-by-step explanation:

a) A binomial experiment must meet the following four conditions:

1. The experiment must consist of 'n' identical trials.

2. Each experiment must result in one of the two outcomes of either success or failure.

3. The probability of success (p) must remain the same from one experiment to the next.

Form a polynomial whose zeros and degree are given.
Zeros: -2, 2, 9; degree: 3
Type a polynomial with integer coefficients and a leading coefficient of 1 in the box below.

Answers

Answer:

the polynomial is: [tex]\mathbf{x^3-9x^2-4x+36=0}[/tex]

Step-by-step explanation:

We need to form a polynomial whose zeros are:

-2,2,9

We can write them as: x=-2, x=2 and x=9

x+2=0, x-2=0 , x-9=0

(x+2)(x-2)(x-9)=0

Now multiplying all terms:

[tex](x(x-2)+2(x-2))(x-9)=0\\(x^2-2x+2x-4)(x-9)=0\\(x^2-4)(x-9)=0\\x^2(x-9)-4(x-9)=0\\x^3-9x^2-4x+36=0[/tex]

So, the polynomial is: [tex]\mathbf{x^3-9x^2-4x+36=0}[/tex]

In a large human population, cranial length is approximately normally distributed with a mean of 185.6 mm and a standard deviation of 12.7 mm. What is the probability that a random sample of size 10 from this population will have a mean less than than 180? a. 0.0174 b. 0.1357 c. 0.0823 d. -1.39

Answers

Answer:

The correct option is  c

Step-by-step explanation:

From the question we are told that

   The mean is  [tex]\mu = 185.6 \ mm[/tex]

   The standard deviation is  [tex]\sigma = 12.7 \ mm[/tex]

   The sample size is  n = 10  

    Generally the standard error of the mean is mathematically represented as

      [tex]\sigma_{x} = \frac{\sigma}{\sqrt{n} }[/tex]

=>    [tex]\sigma_{x} = \frac{ 12.7}{\sqrt{ 10 } }[/tex]

=>    [tex]\sigma_{x} = 4.016[/tex]

Generally the probability that a random sample of size 10 from this population will have a mean less than than 180 is mathematically represented as

     [tex]P(X < 180 ) = P(\frac{ X - \mu }{\sigma_{x} } < \frac{180 - 185.6}{4.016} )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

    [tex]P(X < 180 ) = P(Z < - 1.394 )[/tex]

From the z table  the area under the normal curve to the left corresponding to    -1.394  is  

          [tex]P(X < 180 ) = P(Z < - 1.394 ) = 0.081659[/tex]

=>      [tex]P(X < 180 ) = 0.0823[/tex]

A cylindrical mass has a radius of 5 cm and a height of 6 cm. If the mass of the cylinder is 900 grams, what is the density of the cylinder?

Answers

Approximately 1.9 grams per cubic centimeter.

First you calculate the size of the cylinder in centimeters by taking the area of the base and multiplying it by the height, and then you divide the mass of the cylinder by the volume.

Here is a number in expanded form. (6 x 100) + (1 x 10) + (7 x 1) + (9 x 1/10) + (2 x 1/1000) Write it in standard form. (Using Decimals) ​

Answers

Answer:

617.902

Step-by-step explanation:

(6 * 100) + (1 * 10) + (7 * 1) + (9 *1/10) + (2 *1/1000)=308951/500

308951/500=617.902

The standard form of given number is 6.17 ×10².

What is standard form?

Standard form is a way of writing down in easy form of very large or very small numbers.

Let E is the standard form of given number

E = (6 × 100) + (1 × 10) + (7 × 1) + (9 ×1/10) + (2 ×1/1000)

E =600+10+7+0.9+0.002

E =617.902

E =0.617 × 10³ = 6.17 ×10²

E = 6.17 ×10²

Hence, the standard form of given number is 6.17 ×10²

What is the distance between z1 = 5 - 2i and z2 = 8 + i?

3√2

18

Answers

Answer:

d=2√10

Step-by-step explanation:

The distance between the two points will be given by:

d=√[(x-x1)^2+(y-y1)^2]

point z1=(3-2i) has the coordinates of (3,-2)

point z2=(5-8i) has the coordinates of (5,-8)

thus the distance between them will be:

d=√[(-8-(-2)²+(5-3)²)]

d=√[(-6)²+2²]

d=√(36+4)

d=√40

d=2√10

Answer:

3√2

Step-by-step explanation:

distance formula: d = √(a₁ - a₂)² + (b₁ - b₂)²

a = x, b = y

d = √(x₁ - x₂)² + (y₁ - y₂)²

A car travels at a constant speed.

Use the information given in the picture.

Answers

Answer:

Step-by-step explanation:

Checkpoint A-> time being 1:00pm total miles driven being 120 and

checkpoint B-> time being 3:00pm and the total miles being 208

The distance between two checkpoint A  and B is 208 - 120 = 88 miles

Now the time between the two checkpoints = 3.00 - 1.00 = 2 hours

We need to find car speed between the checkpoints
