Step-by-step explanation:
Formula
m = (y2 - y1)/(x2 - x`1)
Givens
Points M(-5,4) and N(2,-1)
y2 = 4
y1 = -1
x2 = - 5
x1 = 2
Solution
m = (4 - - 1) / (-5 - 2)
m = (4 + 1) / (- 7)
m = (5) / (- 7)
Answer: m (slope ) = 5/-7

What is the surface area of a sphere ?Let, r be the radius of the sphere.
Then the surface area of the sphere = [tex]4\pi r^{2}[/tex] sq. unit
How to find the radius of the toy ball?The structure of the toy ball is sphere.
Given, Surface area of the toy ball = 7543 square millimeter
Let, the radius be r millimeter
∴ [tex]4\pi r^{2}[/tex] = 7543
⇒ [tex]r^{2}[/tex] = [tex]\frac{7543}{4*3.14}[/tex] , where [tex]\pi[/tex] = 3.14
⇒ [tex]r^{2}[/tex] = [tex]\frac{7543}{12.56}[/tex]
⇒ [tex]r^{2}[/tex] = 600.56
⇒ r = [tex]\sqrt{600.56}[/tex]
⇒ r = 24.5 (approx)
Radius = 24.5 millimeter (to nearest tenth)

So, it is proven that the area of triangle ABC is [tex]\frac{1}{2} * a*b*SinC[/tex].
What is a triangle?A triangle is a 2D shape having three sides and the sum of all angles is 180°.
We have,
A ΔABC,
And,
AB = c
BC = a
CA = b
H = Altitude of the triangle,
Now,
Area of triangle [tex]=\frac{1}{2} * Base *Altitude[/tex]
i.e.
Area of triangle ABC [tex]=\frac{1}{2} * a*h[/tex] .....(i)
Now,
Using trigonometric ratios,
[tex]Sin C = \frac{Perpendicular}{Hypotenuse}[/tex]
i.e.
[tex]Sin C = \frac{h}{b}[/tex]
We get,
h = b * SinC
Now,
putting this value in equation (i),
We get,
Area of triangle ABC [tex]=\frac{1}{2} * a*b*SinC[/tex]
So,
It is proved that area of triangle ABC [tex]=\frac{1}{2} * a*b*SinC[/tex] ,
Hence, we can say that it is proven that the area of triangle ABC is [tex]\frac{1}{2} * a*b*SinC[/tex], using trigonometric ratios and the triangle's area formula.

The second column, y, has the entries, 26, 18, 10, 2. A 2 column table with 5 rows. The first column, x, has the entries, negative 4, negative 2, 0, 2. The second column, y, has the entries, 14, 8, 2, negative 4. What is the solution to this system? (1, 0) (1, 6) (8, 26) (8, –22) tables represent two linear functions in a system. A 2 column table with 5 rows. The first column, x, has the entries, negative 4, negative 2, 0, 2. The second column, y, has the entries, 26, 18, 10, 2. A 2 column table with 5 rows. The first column, x, has the entries, negative 4, negative 2, 0, 2. The second column, y, has the entries, 14, 8, 2, negative 4. What is the solution to this system? (1, 0) (1, 6) (8, 26) (8, –22) is deciding which of two gyms to join. Each gym charges a monthly rate plus a one-time membership fee. Lian correctly wrote and solved a system of linear equations by substitution to compare the costs of the memberships. In her work, she substituted an expression for one variable and solved for the other. This resulted in the equation 75 = 75. What can Lian conclude? One gym charges $75 per month. Each gym charges $75 per month. Both gyms charge the same monthly rate and the same membership fee. Both gyms charge the same monthly rate, but not the same membership fee.
Answer:
We want to solve a system of linear equations, we will get that the solutionis (8, -22)A system of equations is a group of equations that we must solve simultaneously. Here we have two lines defined by tables:line 1:x y-4 26-2 180 102 2line 2:x y-4 14-2 80 22 -4Remember that a line is written as:y = a*x + bWhere a is the slope and b is the y-intercept.We know that if a line passes through the points (x₁, y₁) and (x₂, y₂), then the slope can be computed as:With this we can find the slope of the first line, using any pair of the given points, I will use (0, 10) and (2, 2)And we know that the line passes through (0, 10), then the y-intercept is equal to 10.y = -4*x + 10For line 2 we can use the points (0, 2) and (2, - 4), so we get:And the y-intercept is y = 2, then the line is:y = -3*x + 2Now we must solve:-4*x + 10 = -3*x + 210 - 2 = 4x - 3x8 = xNow we evaluate x = 8 in any of the two lines:y = -3*8 + 2 = -22Then the solution of the system is (8, -22)
 Can a probability more than one or 100% Explain.
Answer:
No. Only 1 to 100, logically.
Let's make a scenario to solve this.
So let's say I have an all yellow, 9 quarter spinner board and I spin. It will always land on yellow, so it has a 9/9 or 100% chance of landing on yellow.
Now we must create another scenario.
For instance, I have one bottle, its starting direction was North, and I spin it. It will have a 1/4 chance of landing on North, East, South, or West because it will land in a random direction. For the 4 diagonal directions southeast, southwest, northeast, northwest it will be the same because there are only 4 directions, therefore giving the probability a 1 in 4 chance of landing on either one. :)

Tyrone randomly drew pieces of paper numbered 10 through 50 out of a bowl. After he drew each piece of paper, he recorded the number, returned the piece of paper to the bowl, and then drew the next piece of paper. His results are recorded in the stem-and-leaf plot below.
1 1 1 2 3 4 4 5 7 8
2 0 1 2 2 2 3 4 6 8 9
3 0 0 1 2 3 4 5 5 6 7 9 9
4 3 4 4 5 6 7 8 8 9
Key: 1 6 represents 16
Based on the information in the stem-and-leaf plot, what is the experimental probability that a piece of paper randomly drawn from the bowl will have the number 35 written on it?
A.
B.
C.
D.
Answer:
the answer is D, 1/20
Step-by-step explanation:
i got it wrong the first time but just look at the correct answer choice
The experimental probability is 1/20 that a piece of paper randomly drawn from the bowl will have the number 35 written on it.
What is the stem-and-leaf diagram?A stem-and-leaf diagram is a quantitative assessment of a collection of data in which the data values are divided into a "stem" (the first digit of the number) and a "leaf" (the remainder of the number) (the last digit of the number).
As per the given stem-and-leaf plot, the required solution would be as:
First, determine the total number of pieces of paper pulled from the bowl by totaling the entries in the stem-and-leaf plot.
The stem-and-leaf layout has 40 numbers, with two of them being 35.
As a result, two of the forty pieces of paper drawn had the number 35 scrawled on them.
So, the experimental probability of the piece of paper having 35 on it is :
2/40 = 1/20.
