ALLWAYS REMEMBER OR MEANS ADD AND AND MEANS MULTIPLY
The probability of pulling a red card or a pink card is [tex]\frac{1}{4}[/tex].
Probability: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.Step-by-Step Solution -To remember -
'OR' means add.'AND' means multiply. [tex]0.2(red)+0.05(pink)\\= 0.25\\=\frac{1}{4}[/tex]Therefore, the probability of pulling a red card or a pink card is [tex]\frac{1}{4}[/tex].

Find the slope, if it exists, of the line containing the pair of points.
(8,-6) and (3,9)
Answer:
The slope is -3
Step-by-step explanation:
the equation for finding the slope between two different points is:
M= (y2-y1)/(x2-x1)
Or in other words the change in y over the change in x.
M= (9+6)/(3-8) = 15/-5 = -3.
(sidenote: I added 9 and 6 for the change in y because you cannot subtract a negative number. Instead you have to add it.)

A. -2
B. -1

A hotel charges $80 for the first night and $70 dollars for each additional night. How long can you stay at the hotel if your budget is $850 dollars?
Answer:
12 nights.
Step-by-step explanation:
70×11=770
This means that 11 nights will cost $770.
Now we must add $770 + $80 = $850
The $80 will be an extra night.
So all together it will be 12 nights.

a number which produces a specified quantity when multiplied by itself.
Step-by-step explanation:
What is the slope of the line that passes through the points (2, -3)and (2,13)?
Write your answer in simplest form.
Slope = change in y / change in x
Both x values are the same, they are both 2’s. 2-2 = 0
Because the change in x is 0 the slope is undefined.
An undefined slope means the line is a vertical line ( straight up and down with no angle)
Answer:

Both x values are the same, they are both 2’s. 2-2 = 0

Michelle is planting flowers in her garden. She wants the ratio of daisies to carnations to be 3 to 2. Michelle wants to plant a total of 30 flowers. How many daisies should she plant?
Answer:
18 Daisies and 12 Carnations
Step-by-step explanation:
The total amount of flowers adds to be 30 therefore the amount of daises plus the amount of carnations should equal 30 (d+c=30). Then your ratio of daises to carnations is 3 to 2. Which means that you are going to have three daisies for every 2 carnations.

a piece of wire is 28cm in length is cut into two parts, each part bend to make a square. given that area of square is 416m^2. find the perimeter of each square.
Answer:
25.488 cm and 2.512 cmStep-by-step explanation:
Note: the area of squares is 41 cm² but not 416 m², typo
Let the sides of squares be x and y
Based on given we have equations:
4x + 4y = 28x² + y² = 41Simplify the first equation
4x + 4y = 28x + y = 7x = 7 - ySubstitute x to solve for y:
(7 - y)² + y² = 4149 - 14y + y² + y² = 412y² - 14y + 49 - 41 = 02y² - 14y + 8 = 0y² -7y + 4 =0Solving we get:
y= 6.372 cm or y= 0.628cmThen
x = 0.628 cm or x = 6.372 cmPerimeter of each square is:
4*6.372 = 25.488 cmand
4*0.628 = 2.512 cmHow many different triangles ABC can be formed if C=60∘, c=17√3 and a=34?
Answer:
Jordan, Its been 5 hours, whats the answer?
Step-by-step explanation:
There can be only 1 triangle formed by the given information.
What is triangle?A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices. A triangle is also a polygon.
Given that, ABC can be formed if C=60∘, c=17√3 and a=34
Using the sine law for triangle,
A/sina = B/sinb = C/sinc
34/sina = 17√3/sin60°
⇒ sina = 90°
Since, The triangle ABC is a right triangle,
Hence, There can be only 1 triangle formed by the given information.

Find mzC.
B
(2x – 12)
(9x – 26)
(4x + 43)
Answer:
m<C = 119°
Step-by-step explanation:
Create an equation to find the value of x.
(9x - 26)° = (2x - 12)° + (4x + 43)° (exterior angle theorem of a ∆)
Solve for x
9x - 26 = 2x - 12 + 4x + 43
Add like terms
9x - 26 = 6x + 31
9x - 6x = 26 + 31
3x = 57
Divide both sides by 3
x = 19
✔️m<C = 4x + 43
Plug in the value of x
m<C = 4(19) + 43
m<C = 76 + 43
m<C = 119°
Kiran says that a solution to the equation `x-7=3` must also be a solution to the equation `3x-21=9`.
Write a convincing explanation as to why this is true. Explain how these are equivalent equations.
Answer: This is true because everything in the first equation was multiplied equally to get to the second equation. Every part was multiplied by three. The first equation is x-7=3 and the second can be seen as 3(x-7=3). The three will not affect x seeing that the entire equation had the same thing done to it.

We are performing a one-sample z-test about mean. The sample size is 64, the sample mean 56.7, the sample standard deviation is 30, and the testing mean is 60. What is the value of the test statistic?
Answer:
-0.880
Step-by-step explanation:
Mean X = 56.7
Sd = 30
N = sample size = 64
Null hypothesis:
H0:u = 60
Alternative hypothesis:
H1:u not equal to 60
This corresponds to a 2 tailed test. So we will have to use a z test with 1 mean, known population and standard deviation
Level of significance = 0.05
Z critical value = 1.96
The test statistic
Z = X - u/sd/√n
= 56.7 - 60/30√64
= -0.880
The test statistic is equal to -0.880

Math please help 20 points plus brainly if you can answer each question.
The perimeter of a rectangle is 40 cm. The length is 14 cm.
Let x = width of the rectangle.
Ravi says he can find the width using the equation 2(x + 14) = 40.
Fran says she can find the width using the equation 2x + 28 = 40.
Answer the questions to solve the equations and to compare the steps and solutions.
1. Which of these is the most helpful first step for solving Ravi's equation, 2(x + 14) = 40?
Circle the best answer.
Add 14 to both sides
Subtract 14 from both sides
Divide both sides by 2
Multiply both sides by 2
2. What would your next step be?
Write your answer in the space below.
3. Solve Ravi's equation, 2(x + 14) = 40, to find the width of the rectangle. Show your work.
Write your answer in the space below.
4. Which of these is the most helpful first step for solving Fran's equation, 2x + 28 = 40?
Circle the best answer.
Multiply both sides by 2
Subtract 28 from both sides
Divide both sides by 2
Add 28 to both sides
5. What would your next step be?
Write your answer in the space below.
6. Solve Fran's equation, 2x + 28 = 40, to find the width of the rectangle. Show your work.
Write your answer in the space below.
7. The two equations have different solution steps. Do they have the same solution? Use the distributive property to show why this answer makes sense.
Write your answer in the space below.
Answer:
number 1 is D
number 2 is distribute 2 into x and 14(multiplying) getting 2x+28=40
then subtract 28 from each side 40-28=12 after just simply divide 2x by its self and into 12 getting 6
number 3 is 12
number 4 is subtract 2 from both side
number 5 is divide
number 6 is 6
