What is the probability

Answers

Answer 1

Answer:

Probability = the number of ways of achieving success. the total number of possible outcomes.

Step-by-step explanation:

For example, the probability of flipping a coin and it being heads is ½, because there is 1 way of getting a head and the total number of possible outcomes is 2 (a head or tail). We write P(heads) = ½ .

Write the equation of the line PERPENDICULAR to x = -12 passing through (4,5)​

Answers

Answer:

hope ithelps :)

Step-by-step explanation:

1) x=3 is a vertical line, so if you are looking for a line that is perpendicular you are looking for a horizontal line.

And horizontal lines go through the y-axis and have equations of y= a #

2)the point on the vertical line is (4,-5), it has a y-value of -5

****Every y value on a horizontal line will be the same

so the equation for a perpendicular line would be y= -5

Answers

Answer:

1.65 + 0.09s

Step-by-step explanation:

Given that :

Cost of speaker = $22

Cost per song = $1.25

Sales tax rate = 7.5%

Expression to obtain the amount of sales tax on entire purchase : 0.075(22 + 1.25s)

Expanding the expression :

0.075(22 + 1.25s)

(0.075 * 22) + (0.075 * 1.25s)

1.65 + 0.09375s

Rounding to the nearest hundredth :

Sales tax on entire purchase :

1.65 + 0.09s

Answers

Answer:

(2 n)/3-2/3 = n/6+4/3

(2 n)/3-2/3 = (2 n-2)/3:

(2 n-2)/3 = n/6+4/3

Put each term in n/6+4/3 over the common denominator 6: n/6+4/3  =  n/6+8/6:

(2 n-2)/3 = n/6+8/6

 

n/6+8/6 = (n+8)/6:

(2 n-2)/3 = (n+8)/6

 

Multiply both sides by 6:

(6 (2 n-2))/3 = (6 (n+8))/6

 

6/3 = (3×2)/3 = 2:

2 (2 n-2) = (6 (n+8))/6

 

(6 (n+8))/6 = 6/6×(n+8) = n+8:

2 (2 n-2) = n+8

 

Expand out terms of the left hand side:

4 n-4 = n+8

Subtract n from both sides:

(4 n-n)-4 = (n-n)+8

 

4 n-n = 3 n:

3 n-4 = (n-n)+8

 

n-n = 0:

3 n-4 = 8

Add 4 to both sides:

3 n+(4-4) = 8+4

4-4 = 0:

3 n = 8+4

8+4 = 12:

3 n = 12

Divide both sides of 3 n = 12 by 3:

(3 n)/3 = 12/3

3/3 = 1:

n = 12/3

The gcd of 12 and 3 is 3, so 12/3 = (3×4)/(3×1) = 3/3×4 = 4:

Answers

Answer:

1.08 * 10^57

Step-by-step explanation:

Given that:

Number of atoms in the sun = 1.2 * 10^57

Number of atoms in the rest of the solar system = 1.2 * 10^56

About how many more atoms exist in the Sun than in the rest of the Solar System?

Subtract the number of atoms in solar system from number of atoms in sun

(Number of atoms in sun - number of atoms in rest of the solar system)

(1.2 * 10^57) - (1.2 * 10^56)

= 1.08 * 10^57 (using calculator)

what is the expression for f(x) when we rewrite 64^x/4^5x-1 as 4^f(x)

Answers

Answer: f(x)= -2x+1

Step-by-step explanation:

The expression for f(x), when we rewrite [tex]\frac{64^x}{4^{5x-1}}[/tex] as [tex]4^{f(x)}[/tex] will be [tex]4^{-2x+1}[/tex].

What is expression ?

Expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

We have,

[tex]\frac{64^x}{4^{5x-1}}[/tex]

So,

Now, to rewrite in form of [tex]4^{f(x)}[/tex],

So,

Rewrite the given expression in the form of 4,

i.e.

[tex]\frac{64^x}{4^{5x-1}}[/tex]

[tex]=\frac{(4^3)^x}{4^{5x-1}}[/tex]

[tex]=\frac{(4^3x)}{4^{5x-1}}[/tex]

NOw,

Using Exponent rule,

We get,

[tex]=4^{3x-(5x-1)}=4^{3x-5x+1}[/tex]

On solving we get,

[tex]=4^{-2x+1}[/tex]

So,

[tex]4^{f(x)}=4^{-2x+1}[/tex]

Hence, we can say that the expression for f(x), when we rewrite [tex]\frac{64^x}{4^{5x-1}}[/tex] as [tex]4^{f(x)}[/tex] will be [tex]4^{-2x+1}[/tex].

-4/1 it would be y=-4x in y=mx+b

Answer:

y = -2x

Step-by-step explanation

slope intercept form: y = mx + b

m is slope and b is y-intercept

1. lets find y-intercept cuz thats easiest

the line crosses (0,0) at the y-axis so there is no y-intercept

2. to find slope rise/run

we'll start at (0,0) since that's the y-intercept

3. slope is rise/run = -2/1 = -2

it's negative becuase it's going left

_____________________________________________________

another way you can find slope is by the equation y2 - y1/ x2 - x1

take 2 random points from the line, i will use (0,0) and (-2,4)

4 - 0/ -2 - 0 = 4/-2 = -2

slope is -2

How do you graph Y=1.2x-4 ?

Answers

Step-by-step explanation:

Use the y=mx+b reference

the b refers to the y intercept which in your case is -4

so on the graph you would put -4 on the y line so at (0,-4)

Then the m or the slope which is 1.2 means from the point (0,-4) you move 1.2 units up and 1 unit to the right forever to create your line so you continuously move 1.2/1 and -1.2/-1

The required, graph of the linear equation y = 1.2x-4 is shown in the image attached below.

To graph the equation y = 1.2x - 4:

Set up the coordinate plane with the x and y axes.Label the axes as "x" and "y" with numerical markers.Plot the y-intercept: When x = 0, y = 1.2 * 0 - 4 = -4. Plot the point (0, -4).Identify the slope: The coefficient of x is 1.2, which represents the slope.Use the slope to find another point: Starting from (0, -4), move 1 unit to the right (increase x by 1) and 1.2 units upward (increase y by 1.2). Plot the point (1, -2.8).Draw a straight line through the two points you plotted.

The graph of Y = 1.2x - 4 will be a straight line that passes through the points (0, -4) and (1, -2.8), and it will continue infinitely in both directions. The line will slope upwards from left to right with a slope of 1.2.
