The greatest relative frequency is the relative frequency that gives the highest probability

The greatest relative frequency given discrete random variable X, when X∼B(4,110) is  x=3

For a discrete random variable, the smaller the value of the variable, the higher its relative frequency.

This means that:

A variable x = 0 would have a greater relative frequency than a variable x =  n, where n > 0

This means that, the greatest relative frequency given discrete random variable X, when X∼B(4,110) is  x=3

Answer:

Step-by-step explanation:

I am not sure how much to answer. I'll confine myself to the written question.

Equation

24 students 1 0iece  of pizza each = 25.65

 1 piece of pizza = x

Set up a proportion

24 students are given 24 pieces of pizza -- Cost 25.65

1 student 1 piece of pizza = x

Solution

24 / 1 = 25.65/x               Cross Multiply

24x = 1 * 25.65                Divide both sides by 24

24x/24 = 25.65/24

x  = 1.07 / slice.

The estimated proportion is given by:

And that represent 71.4%

Step-by-step explanation:

The number of dogs that are not puppies is 17, the number of adult dogs without long hair is 6, the number of puppy dogs with long hair is 8 and the number of puppy dogs without long hair is 7.

To complete the chart it is necessary to determine:

Number of dogs that are not puppies:

Adult dogs without long hair:

Puppy dogs with and without long hair

Total of puppy dogs = 15, this number can be obtained by adding 9+6 or 7+8. From these combinations, the only one that meets the rule "There are 6 more dogs that have long hair than dogs that do not have long hair" is 8 puppies with long hair and 7 puppies without long hair.

Note: This question is not written correctly; here is the correct and complete question.

Samantha gathered the following information on a given day at the dog park.

There are 32 dogs playing at the dog park.

15 of the dogs are puppies.

11 of the dogs are not puppies and have long hair.

X= 7 units

Step-by-step explanation:

since the triangles are similar the ratio. of their common sides will be equal so,

BE/BD= BC/BA

(4X-8)/18= 45/22.5

4X -8 = 18×2

4X= 36-8

X= 28/4

X= 7

Problem 5

------------------

Work Shown:

a = 15

b = unknown

c = 25

a^2 + b^2 = c^2

15^2 + b^2 = 25^2

225 + b^2 = 625

b^2 = 625 - 225

b^2 = 400

b = sqrt(400)

b = 20

The rectangle is a = 15 by b = 20 to get an area of ab = 15*20 = 300 square inches.

=======================================================

Problem 6

Answer:

------------------

Work Shown:

Part A)

area = base*height/2

area = 8*12/2

area = 96/2

area = 48

Part B)

a^2 + b^2 = c^2

8^2 + b^2 = 12^2

64 + b^2 = 144

b^2 = 144 - 64

b^2 = 80

b = sqrt(80)

b = sqrt(16*5)

b = sqrt(16)*sqrt(5)

b = 4*sqrt(5)

Therefore,

area = base*height/2

area = a*b/2

area = 8*4*sqrt(5)/2

area = 16*sqrt(2)

=======================================================

Problem 7

------------------

Work Shown:

area = 81

area = x^2

x^2 = 81

x = sqrt(81)

x = 9

The side lengths of the square are 9 cm each.

P = perimeter

P = 4x

P = 4*9

P = 36

Problem 8

------------------

Work Shown:

The horizontal base of 10 is cut in half to get 5.

a = 5 = horizontal side

b = unknown height

c = 20 = hypotenuse

a^2 + b^2 = c^2

5^2 + b^2 = 20^2

25 + b^2 = 400

b^2 = 400 - 25

b^2 = 375

b = sqrt(375)

b = sqrt(25*15)

b = sqrt(25)*sqrt(15)

b = 5*sqrt(15)

area = base*height/2

area = a*b/2

area = 5*5*sqrt(15)/2

area = 12.5*sqrt(15)

On comparing [tex]x^{2} +6x+8 =0[/tex] with the general form,

a=1, b=6, c=8

If discriminant D=b²-4ac is greater than zero, the quadratic equation will have two distinct real roots, if D is less than zero, roots will be imaginary.

So, discriminant D for f(x)=0 will be:

[tex]b^{2} -4ac[/tex] = [tex]6^{2} -4*1*8 = 4[/tex] i.e. greater than zero.

So, the quadratic function [tex]f(x) = x^{2} +6x+8[/tex] will have two real distinct

roots.

Similarly, h(x), k(x), and t(x) will have real roots since their discriminants are greater than zero.

Thus, Function f(x), h(x), k(x) and t(x) will have real roots while function g(x) and p(x) will have imaginary roots.

Step-by-step explanation:

-5k²- 22k + 15

(a)

-5( -3/5 )² - 22( -3/5 ) + 15

     -1.8 + 13.2 + 15 = 26.4 or

-125 - 110 + 15 = -220

(c)

-5 ( 3/5 )²- 22( 3/5 ) + 15

-1.8 - 13.2 + 15 = 0 or

First, we make the denominators of 1/4 and 3/8 the same as the LCM (= 8)

-> 1/4 = 1 x 2 / 4 x 2 = 2/8
-> 1 - ... = 2/8 + 3/8 = 5/8

The missing fraction = 1 - 5/8 = 3/8.

Answer:

Step-by-step explanation:

First find the length of the two equal sides. Use Pythagoras.

c^2 = a^2 + b^2

c = ?

a = 7

b = 1/2 48 = 24

c^2 = 24^2 + 7^2

c^2 = 576 + 49

c^2 = 625                Take the square root of 625

√c^2 = √625

c = 25

Both of the equal sides = 25

Answer:

∠2 = 41°

Step-by-step explanation:

This is because, all three interior angles in a triangle will have a sum of 180 degrees.

So given that we have two angles, 90 degrees(right angle) and 49 degrees, we can replace angle 2 as our unknown value(a variable) and make it equal to 180 degrees then solve for x;

49 + 90 + x = 180

139 + x = 180

-139        -139

x = 41°, ∠2 = 41°
