The possible outcomes of the fair coin and the dice is the sample space
The list of possible outcomes is: {H1,H2,H3,H4,H5,H6,T1,T2,T3,T4,T5,T6}The probability of getting a head and a 3 is 1/12How to list the possible outcomesThe items are given as:
Coin = 1
Dice = 1
The sample space of both items are:
Coin = {H,T}
Dice = {1,2,3,4,5,6}
So, the list of possible outcomes is: {H1,H2,H3,H4,H5,H6,T1,T2,T3,T4,T5,T6}
The probability of getting a head and a 3From the above list, there is only one outcome that has a head and a 3 out of 12 possible outcomes
So, the probability of getting a head and a 3 is:
p = 1/12
Hence, the probability of getting a head and a 3 is 1/12

What is the area of a rectangle with width =7 inches and diagonal =25 inches
Answer:
The area of any rectangular place is or surface is its length multiplied by its width. For example, a garden shaped as a rectangle with a length of 10 yards and width of 3 yards has an area of 10 x 3 = 30 square yards. A rectangular bedroom with one wall being 15 feet long and the other being 12 feet long is simply 12 x 15 = 180 square feet.

Mrs. Worthington purchased single slices of pizza for 24 students. The cost for 24 slices of pizza is $25.65. What is the cost for one slice of pizza? ______
Complete the chart.
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.
Determine which functions have two real number zeros by calculating the discriminant, b2 – 4ac. check all that apply. f(x) = x2 6x 8 g(x) = x2 4x 8 h(x) = x2 – 12x 32 k(x) = x2 4x – 1 p(x) = 5x2 5x 4 t(x) = x2 – 2x – 15
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.
Given quadratic functions are:
[tex]1) f(x)= x^{2} +6x+8\\2)g(x) = x^{2} +4x+8\\3)h(x) = x^{2} -12x+32\\4)k(x)=x^{2} +4x-1\\5)p(x)=5x^{2} +5x+4\\6)t(x) = x^{2} -2x-15[/tex]
What is the general form of a quadratic equation?The general form of a quadratic equation is:
[tex]ax^{2} +bx+c=0[/tex]
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.

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

Which value for x will result in the greatest relative frequency given discrete random variable X, when X∼B(4,110)? x=5 x=1 x=0 x=3
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
How to determine the greatest relative frequencyFor 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

Problem 5
Answer: 300 square inches------------------
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:
Part A) The area = 48 square inchesPart B) The area = 16*sqrt(2) square inches------------------
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
Answer: 36 cm------------------
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
Answer: 12.5*sqrt(15)------------------
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)

Please solve this equation
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°
