Answers

Answer:

A - since the median can be any number we know of. B - Again the median can be any number we know of, since it is a undetermined amount. E - The range can be 10 flights, this is because it is not a determiend value, and it is possible for the value to be 10.

Step-by-step explanation:

Wrong answer reasoning:

The mode doesnt need to be 9 if there is more than 1 mode, so that isnt it. Eliminating D. The mean can most definatly be determinded if we know the values. This elimnates C. The mean can be 6.875, but we dont know, so we can assume it IS 6.875. This eliminates F.

Can anyone tell me what the answer to this problem is and the explination?

Answers

The figure shown above is triangle. The area of the triangle is a= 1/2base times height.

Base  is 10 .  The height is 6.

A= 1/2bh

A= 1/2*10*6

A= 1/2*60

A= 30

Or you can find the area of the triangle separately and add them up.

First triangle :

The half of the base is 10/2= 5

B= 5  H= 6

A= 1/2*6*5

A=  15

Second triangle :

b= 5

h= 6

a= 1/2*5*6

a= 15

Add up them both areas 15+15= 30

Area of a square is l x w=9x9=81
Area of a triangle is 1/2(bxh)=1/2(9x7)=31.5
As there r 4 triangles, multiply 31.5 by 4 to get the tot surface area of the triangles as 126.
Now add the square area to the triangles area for the total surface area.

In southern California, a growing number of individuals pursuing teaching credentials are choosing paid internships over traditional student teaching programs. A group of eleven candidates for five local teaching positions consisted of six who had enrolled in paid internships and five who enrolled in traditional student teaching programs. All eleven candidates appear to be equally qualified, so five are randomly selected to fill the open positions. Let Y be the number of internship trained candidates who are hired. (a) Does Y have a binomial or hypergeometric distribution

Answers

Answer:

Candidates are chosen without replacement, thus trials are dependent, meaning that Y has a hypergeometric distribution.

Step-by-step explanation:

Difference between hypergeometric and binomial distributions:

In the hypergeometric distribution, trials are dependent of other trials, while in the binomial distribution, they are independent. This can be examplified that in the hypergeometric distribution, the candidates are chosen from a set without replacement, while in the binomial distribution they are chosen with replacement.

In this question:

Candidates are chosen without replacement, thus trials are dependent, meaning that Y has a hypergeometric distribution.

Find the length of the unknown side.
25 cm
15 cm

Answers

Answer:

b = 20 cm.

Step-by-step explanation:

Define and explain:

This is a right triangle, so the Pythagorean Theorem applies.

The Pythagorean Theorem states that the sum of the squared legs will equal the squared length of the hypotenuse.

The legs of a triangle are the sides that form the right angle.

The hypotenuse is the longest side; the hypotenuse is always diagonal from the small square indicating a right angle.

Solve:

[tex]a^2+b^2=c^2[/tex]

[tex]a,b-legs[/tex]

[tex]c-hypotenuse[/tex]

[tex]15^2+b^2=25^2[/tex]

[tex]225+b^2=625[/tex]

[tex]625-225=400[/tex]

[tex]b^2=400[/tex]

[tex]b=20[/tex]

Conclude:

Therefore, the length of the unknown side is 20 centimeters.

A tray contains 16 chocolate chip cookies and 12 oatmeal raisin cookies. HOw many ways can a child select 3 cookies that include at least 1 chocolate chip cookie

Answers

Answer:

Number of ways chosen cookies = 8 ways

Step-by-step explanation:

Given;

Total number of chocolate chip cookies = 16

Total number of oatmeal raisin cookies = 12

Total number of cookies choose = 3

At least 1 chocolate cookie

Find:

Number of ways chosen cookies

Computation;

Number of total ways = 2³

Number of total ways = 8

If at least on cookie is chocolate cookie,

Number of ways chosen cookies = Number of total ways - 1

Number of ways chosen cookies = 9 - 1

Number of ways chosen cookies = 8 ways

What is the magnitude of 8 and -8?

Answers

9514 1404 393

Answer:

  8 and 8

Step-by-step explanation:

The magnitude of a number is the positive distance it is from the origin. The number 8 is 8 units from the origin (in the + direction). The number -8 is also 8 units from the origin (in the - direction).

Both 8 and -8 have a magnitude of 8 units.

what is the average rate of change of f(x) = (x + 3)2 − 2

Answers

Answer:

When we have a function f(x), the average rate of change in the interval (a, b) is:

[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]

In this case, we have the function:

f(x) = (x + 3)^2 - 2

(but we do not have the interval, and I couldn't find the complete question online)

So if for example, we have the interval (2, 4)

The average rate of change will be:

[tex]r = \frac{(4 + 3)^2 - 2 - (2 + 3)^2 + 2}{4 - 2} = \frac{24}{2} = 12[/tex]

If instead, we want the rate of change in a differential dx around the value x, we need to differentiate the function (this is way more complex, so I will define some rules first).

Such that the rate of change, in this case, will be:

f'(x) = df/dx

For a function like:

g(x) = x^n + c

g'(x) = n*x^(n - 1)

And for:

h(x) = k( g(x))

h'(x) = k'(g(x))*g'(x)

So here we can write our function as:

f(x) = k(g(x)) = (x + 3)^2 - 2

where:

g(x) = x + 3

k(x) = x^2 - 2

Then:

f'(x) = 2*(x + 3)*1 = 2*x + 6

That is the rate of change as a function of x (but is not an "average" rate of change)
