The probability of getting 2 on the first roll and not getting 4 on the second roll is 5/36.
The two events mentioned are independent.
Given, first event getting 2 on the first roll and second event getting 4 in second roll.
So, the first roll of the die is independent of the second roll.Therefore, the probabilities can be directly multiplied.
P (getting first 2) = 1/6
P (no second 4) = 5/6
Therefore P (getting first 2 and no second 4) = 1/6 x 5/6 = 5/36

Use the point slope form to write the equation of a line that passes through the point (1,-17) with slope 4
The equation of line passing through (1, -17) with slope 4 will be y = 4x - 21 .
What is the slope intercept form of a line ?
The equation of line that can be written as y = mx + c, where m is the slope and c is the line's y-intercept, is known as a slope intercept form.
The equation of a line which is passing through point (1 , -17) with slope m = 4 can be found by using the slope intercept form which is given by :
y = mx + c
Here ; m is the slope and c is the y - intercept of the line.
So ;
The point given is (x , y) = (1, -17) and slope m = 4. Let's use these values to find out the equation of the line. But before that let's find out the value of y-intercept (c).
-17 = (4 × 1) + c
c = - 17 - 4
c = -21
Hence , the equation of line passing through (1, -17) will be :
y = 4 × x + (-21)
or
y = 4x - 21
Therefore , the equation of line passing through (1, -17) with slope 4 will be y = 4x - 21 .

choose the equation that represents the line that passes through the point (6, −3) and has a slope of one half. (1 point)
The equation that represents the line that passes through the point (6, −3) and has a slope of one half is 2y - x = 13.
The equation of a line is represented as,
y = mx + c equation1
x and y are the coordinates of the point from where the line is passing and m is the slope of the line.
As per the question the line is passing from the point (6, -3). This means value of x = 6 and that of y = -3. The slope of line is (1/2), means m = (1/2).
The slope of the line through the point (-1,6) can also be written as (y - 6)/(x - (-1)) = (y-6)/(x+1).
i.e., m = (y-6)/(x+1)
On equating both the values of m, we will get
(y-6)/(x+1) = 1/2
On simplifying, we get
2y - 12 = x +1
or 2y - x = 13
The equation that represents the line that passes through the point (6, −3) and has a slope of one half is 2y - x = 13.

We take the value 2 for which y(2)=4 and [tex]y^{2}[/tex]=2 and see that y(x)=[tex]x^{2}[/tex] is a function and [tex]y^{2}[/tex]=x is a relation.
Domain is the set of values that a variable can take in an algebraic expression.For the equation y(x)=[tex]x^{2}[/tex], x can take any value from negative infinity to positive infinity so we can say that the domain for x is (-∞,∞). For the equation [tex]y^{2}[/tex]=x, x can take any value greater than or equal to zero. Since x=[tex]y^{2}[/tex] we can't take a negative value for x because squared numbers are always positive, so the domain of x will be [0,∞). The common domain for both the equations is [0,∞). Let us choose a value from this common domain,let's say 2. Then for
y(x)=[tex]x^{2}[/tex]⇒y(2)=4 ...(i)
[tex]y^{2} =x[/tex]=2 then y=±[tex]\sqrt{2}[/tex]...(ii)
A function always has an output variable and one or more input variables.For first equation, y is the output variable and x is the input variable. A relation states that two expressions are equal and one is not dependant on another. For equation (i) y is dependant on x but in equation (ii) both the variables are independant.
Thus we can conclude that y(x)=[tex]x^{2}[/tex] is a function and [tex]y^{2}[/tex]=x is a realtion.

Enter your answer, in the form (x, y, z), in the boxes in simplest terms.
Step-by-step explanation:
the second equation gives us right away
y = 4 - 3x
we can use that now in the 3rd equation :
-2(4 - 3x) + 2z = 4
-8 + 6x + 2z = 4
6x + 2z = 12
3x + z = 6
z = 6 - 3x
now we use both in the 1st equation :
-2x + 3(4 - 3x) - (6 - 3x) = -2
-2x + 12 - 9x - 6 + 3x = -2
-8x + 6 = -2
-8x = -8
x = 1
y = 4 - 3x = 4 - 3×1 = 4 - 3 = 1

The rate of change of the surface area of the cylinder is approximately to 18.473 square meters per second.
What is the rate of change of the surface area of a cone?
In this question we find a formula for the surface area of a cone, of which we must estimate its rate of change by applying derivative rules and the concept of rate of change. The rate of change is the first derivative of the equation:
ds / dt = 2π · r · (dr / dt) + π · √(r² + h²) · (dr / dt) + π · r · [0.5 / √(r² + h²)] · [2 · r · (dr / dt) + 2 · h · (dh / dt)]
If we know that r = 3 m, h = 4 m, dr / dt = 0.5 m / s and dh / dt = 0.2 m / s, then the rate of change of the surface area of the cone is:
ds / dt = 2π · (3 m) · (0.5 m / s) + π · √[(3 m)² + (4 m)²] · (0.5 m / s) + π · (3 m) · [0.5 / √[(3 m)² + (4 m)²] · [2 · (3 m) · (0.5 m / s) + 2 · (4 m) · (0.2 m / s)]

James, fay and sal share 160 apples. james got 1/4 of the apples. fay and sal shared the remainder in the ratio 3:2 respectively. 1) find how many oranges fay received 2) how many oranges did sal receive than james?
Using the ratio given in the question,
Apples received by Fay are 72.Apples received by James are 40.Apples received by Sal are 48.What is Ratio?The relation between the quantities of two or more objects—referred to as a ratio—indicates how much of one object is contained in the other. The ratio formula can be used to represent a ratio as a fraction. The ratio formula is given as, for any two quantities, let's assume a and b.
a:b = a/b
Given that James, Fay and Sal share 160 apples.
Total number of apples = 160
Hence, apples received by James = 1/4(160)
= 40 apples
Remaining apples = 160 - 40 = 120 apples
It is also given that the remainder is shared by Fay and Sal in the ratio 3:2.
Hence, the total share will be 3+2=5
So, we can write that Fay's share will be 3/5 of total apples and Sal's share will be 2/5 of the total apples.
Fay's share = 3/5(120)
=3(24)
=72 apples
Sal's share = 2/5(120)
=2(24)
=48 apples
Therefore, the number of apples with Fay is 72.
The number of apples with Sal is 48.

The angles shown are same side interior angles, and when the lines are parallel, same side interior angles add to 180 degrees
< 1 + <2 = 180
x+23 + x+53 = 180
Combine like terms
2x+ 76 = 180
Subtract 76 from each side
2x+76-76 = 180 -76
2x = 104
Divide by 2
2x/2 = 104/2
x =52
Answer:
x = 52
Step-by-step explanation:
Angle 1 and angle 2 are on the same side, and on the inside of the interior. This means that when added together they = 180
We can set up an equation
x+23+x+53 = 180
Simplify: 2x + 76 = 180
Subtract 76 from both sides
2x = 104
Now divide by 2

The ending number is related to the starting number by n + 9.
To start with this magic number puzzle, let us take a positive number and a negative number. After that we have to perform some simple mathematical operations,
Taking positive number as 10 and negative number as -8.
Now, performing the mathematical operations as described in the next steps.
First starting with positive number which is 10.
Step-1. Add 10
So, 10+10 = 20
Step-2. Multiply by 2
So, 20×2 = 40
Step-3. Subtract 2,
So, 40 - 2 = 38
Step-4. Divide by 2,
So, 38/2= 19
Number chosen in the starting was 10 and at the end it became 19. The number 9 got added to 10.
Now, performing the steps on our negative number which is -8,
Step-1. Add 10
So, 10-8=2
Step-2. Multiply by 2
So, 2×2 = 4
Step-3. Subtract 2
So, 4-2 = 2
Step-4. Divide by 2
So, 2/2 = 1.
Number chosen in the starting was -8 and after performing the steps it became 1.
Now, for any number 'n',
Step-1. Adding 10
So, n+10
Step-2. Multiply by 2
So, 2(n-10) = 2n+20
Step-3. Subtract 2
So, 2n+20-2 = 2n+18
Step-4. Divide by 2.
So, (2n+18)/2 = n+9
The number taken in the starting was n and now it became n+9.
So the ending number becomes 9 times more in the end then the starting number.
