If you write everything down, you can get 0,1,2,3 or 4 heads. The probabilities are: 1/16, 4/16, 6/16, 4/16, and 1/16. Notice, the probabilities add up to 16/16 = 1. You toss 4 fair coins.
What is probabilities?
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.
An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes.
Statistics is the study of events that follow a probability distribution.

What is the graph of the function
f(x)=−⌊x⌋
Answer:
Step-by-step explanation:
The equation being shown in the question is the absolute value of x. Absolute values when graphed show up as a V-shaped graph pointing upwards. This is because whatever value is passed as an input will output a positive, regardless of whether the input is positive or negative. Meaning that both 4 and -4 will output 4. That is why the graph is a V-shaped because the outputs repeat for both positive and negative inputs. In this case since the negative is outside the absolute value brackets the positive value given from the absolute value of the input will be turned into a negative. So this will cause the V-shape graph to be reflected across the x-axis. As seen in the attached picture below.

Answer:
B and A
Step-by-step explanation:
Calculate distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
(1) with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (6, 8)
d = [tex]\sqrt{6-0)^2+(8-0)^2}[/tex]
= √(6² + 8²)
= √ (36 + 64)
= √ 100
= 10 → B
(2)
Using (x₁, y₁ ) = (- 5, 3) and (x₂, y₂ ) = (3, 15)
d = √ (3 + 5)² + (15 - 3)²
= √ 8² + 12²
= √ 64 + 144
= √ 208

Javier and his friends go out to eat. The restaurant they chose automatically adds a 15% gratuity to their food bill since they are a party of 12. The total bill after the automatic 15% gratuity was $213.90. Because they received such good service, the group decided to add an extra $20 to the total bill as an additional tip.
So, instead of leaving a 15% tip, Javier and his friends ended up leaving a tip that was about _% of the food bill.
Question 3
Write the rational number as a decimal.
Answer: -2.2
Step-by-step explanation:
-10 is the most possible that can be divided by 5, resulting in -2.
The leftover 1 is divided by 5, resulting in .2.
The decimal ends up being -2.2.
Answer:
-2.2 or -1.2
Step-by-step explanation:
When you want to write a decimal as a fraction, you simply divide the numerator with the denominator. So when you divide -11 by five that would be a -2.2. Or if it is -1 1/5 the answer would be -1.2. I cant really tell what that number is.
the topic is piecewise functions, can someone help? i’m a little confused :)
Given:
The piecewise function is:
[tex]f(x)=\begin{cases}x+5&x<-2\\x^2+2x+3&x\geq -2\end{cases}[/tex]
To find:
The values of [tex]f(-4),f(-2),f(0),f(3)[/tex].
Solution:
For [tex]x<-2[/tex], the function is
[tex]f(x)=x+5[/tex]
For [tex]x\geq -2[/tex], the function is
[tex]f(x)=x^2+2x+3[/tex]
a) The value of [tex]f(-4)[/tex] is:
[tex]f(-4)=-4+5[/tex]
[tex]f(-4)=1[/tex]
b) The value of [tex]f(-2)[/tex] is:
[tex]f(-2)=(-2)^2+2(-2)+3[/tex]
[tex]f(-2)=4-4+3[/tex]
[tex]f(-2)=3[/tex]
c) The value of [tex]f(0)[/tex] is:
[tex]f(0)=(0)^2+2(0)+3[/tex]
[tex]f(0)=0-0+3[/tex]
[tex]f(0)=3[/tex]
d) The value of [tex]f(3)[/tex] is:
[tex]f(3)=(3)^2+2(3)+3[/tex]
[tex]f(3)=9+6+3[/tex]
[tex]f(3)=18[/tex]
Therefore, the required values are [tex]f(-4)=1,f(-2)=3,f(0)=3,f(3)=18[/tex].

4x - 35 = 234
Solve for 'x'.
Answer:
X= 67.25
Step-by-step explanation:
4x-35=234
Add 35 to both sides
4x= 269
Divide both sides by 4
X= 67.25
Answer:
x = 67,25
Step-by-step explanation:
Here it is given that,
x is an unknown to know. Since we are intelligent students, we will bring the unknowns to the left limb, and the numbers known in the right limb.[tex]\:[/tex]
We can write this matematically as,
[tex]\rightarrow 4x - 35 =234[/tex]
Move the constant to the right,
[tex]\rightarrow 4x =234 + 35[/tex]
Add the numbers,
[tex]\rightarrow 4x =269[/tex]
Divide both sides of the equation by 4,
[tex]\rightarrow x =\frac{269}{4}[/tex]
We determine the value of x,
[tex]\rightarrow \underline {x=67,25}[/tex]
Which equation below represents a line with a slope of - 2/3 that passes through the point (-4.5 , 10)?
A. y = - 2/3 x + 10
B. y = - 2/3 x +2.7
C. y = - 2/3 x + 7
D. y = - 2/3 x + 13
pls explain the answer if possible ^^
Answer:
Option C
Step-by-step explanation:
If a line passes through a point, then that point is called a solution to the line's equation. Substituting the x and y values of that solution into the equation will give a true statement. So, to find out which option is correct, we can substitute the x and y values of (-4.5, 10) into each equation and see if the result is a true statement.
Let's try this with option C. To make things easier, convert -4.5 into decimal form: [tex]-4\frac{1}{2}[/tex]. Substitute [tex]-4\frac{1}{2}[/tex] for x and 10 for y in the equation, then solve:
[tex]y = -\frac{2}{3} x+7\\\\10 = -\frac{2}{3} (-4\frac{1}{2} )+7\\10 = -\frac{2}{3} (-\frac{9}{2})+7\\10 = 3+7\\10 = 10[/tex]
10 does equal 10, so this is a true statement. Option C is the right answer.
what is 10c + 20 = 40 C =
Answer: c = 2
Step-by-step explanation:
First you write out your equation: 10c + 20 = 40
Next, since the equation is adding, you can subtract 20 the constant on both sides of the equation:
10c + 20 = 40
- 20 - 20
The 20s cancel each other out and 40 - 20 is 20.
Our new equation looks like: 10c = 20
Now to find the value of C you are going to divide 10 on both sides because the equation is multiplying.
10c divided by 10 is just c and 20 divided by 10 is 2.
Therefore, you are left with c = 2

A small airplane is approaching a stationary crowd at 100 meters per second. The engine of the plane is emitting a sound of 485 Hz. What is the apparent frequency as it approaches the crowd?
Answer:
695.87 Hz
Step-by-step explanation:
Using the equation for Doppler shift, the frequency of the apparent sound is f' = f(v ± v')/(v ± v") where f = frequency of sound emitted by the plane's engine = 485 Hz, v = speed of sound in air = 330 m/s, v' = speed of crowd(detector) = 0 m/s (since the crowd are stationary) and v" = speed of plane(source) = 100 m/s
So, f' = f(v ± v')/(v ± v")
f' = f(v ± 0)/(v ± v")
f' = fv/(v ± v")
Since the source moves towards the detector, we use a minus a minus sign in the denominator to get a shift upwards in frequency since a shift upwards means the objects are moving closer to each other.
So,
f' = fv/(v - v")
Substituting the values of the variables into the equation, we have
f' = 485 Hz × 330 m/s/(330 m/s - 100 m/s)
f' = 160050 Hzm/s ÷ 230 m/s
f' = 695.87 Hz

A factor of a number that, when multiplied by itself, gives the original number is called a square root.
The square root of 3 is 9.
The integer that has the nearest to the integer that has a square root of 3 is √10.
What is a square root?A factor of a number that, when multiplied by itself, gives the original number.
We have,
9 is a square root of 3.
The nearest square root of 3 can be 8 or 10.
The value of the square root of 8.
= √8
= 2.83
The value of the square root of 10:
= √10
= 3.16
The nearest can be determined by finding out the difference between each of its values with 3.
For √8,
= 3 - 2.83
= 0.17
For √10,
= 3.16 - 3
= 0.16
We see that √10 is nearest to the integer that has a square root of 3.
Thus the integer that has the nearest to the integer that has a square root of 3 is √10.
