A bag contains 8 red pens, 7 blue pens, and 14 black pens. Denato will pull a pen from the bag.
When Denato pulls a pen from the bag, how many outcomes are possible?
A.8
B.7
C.14
D.29
20 POINTS!!
The probability helps us to know the chances of an event occurring. The number of possible outcomes When Denato pulls a pen from the bag is 29.
What is Probability?The probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
Given that the bag has 8 red pens, 7 blue pens, and 14 black pens. Therefore, if Denato will pull a pen from the bag the number of possibilities will be the sum of all the number of pens.
Number of Possibilities = 8 + 7 + 14 = 29
Thus, the number of possible outcomes When Denato pulls a pen from the bag is 29.

the figure is symmetric about the x- and y-axis. what is the area of the figure below
Answer:
126 units²
Step-by-step explanation:
Draw 5 vertical lines BR, CQ, EO, GM, HL and we will have 4 trapezoids and 2 rectangles.
Trapezoid ABRS ≅ trapezoid IHLK
Trapezoid DEOP ≅ trapezoid FEON
Rectangle BCQR ≅ rectangle GHLM
Area of trapezoid is [tex]\frac{b_{1} +b_{2} }{2}h[/tex]
Area of rectangle is [tex]lw[/tex]
The total area of the figure is: ( 2 × [tex]A_{ABRS}[/tex] + 2 × [tex]A_{BCQR}[/tex] + 2 × [tex]A_{DEOP}[/tex] )
In trapezoid ABRS: [tex]b_{1}[/tex] = 6, [tex]b_{2}[/tex] = 8 and h = 3 ⇒
2 × [tex]A_{ABRS}[/tex] = 2 × [3(6 + 8) ÷ 2] = 42 units²
In rectangle BCQR: l = 6 and w = 3 ⇒
2 × [tex]A_{BCQR}[/tex] = 2 × (6 × 3) = 36 units²
In trapezoid DEOP: [tex]b_{1}[/tex] = 6, [tex]b_{2}[/tex] = 10 and h = 3 ⇒
2 × [tex]A_{DEOP}[/tex] = 2 × [3(6 + 10) ÷ 2] = 48 units²
[tex]A_{total}[/tex] = 42 + 36 + 48 = 126 units²

miles. If the area of the playground is 5/8
square miles, what is its width? Input your answer as a fraction. Need help ASAP for a grade
Answer:5/4
Step-by-step explanation:
Area = length* width
5/8 = 1/2 * width
Width = 5/4
Answer:
5/4 miles.
Step-by-step explanation:
Width = area / length
= 5/8 / 1/2
= 5/8 * 2
= 10/8
= 5/4 miles.

A company orders 18 boxed lunches from a deli for $223.20. If each boxed lunch costs the same amount, what is the unit cost of each boxed lunch?
Answer:
12.40
Step-by-step explanation:
[tex]223.20 \div 18[/tex]
that will give you the answer of 12.40 for each unit.
Answer:
Step-by-step explanation:
1 box costs x amount
18 boxes cos 223.20
Cross multiply
223.20 * 1 = 18 x
Divide by 18
223.20 / 18 = 18x / 18
x = 12.40
Cost of 1 box is 12.40

Find an exact value. Cos 75° negative square root of six plus square root of two quantity square root of six minus square root of two divided by four quantity negative square root of six plus square root of two divided by four square root of six minus square root of two
Answer:
√2(√3 - 1)/4
Step-by-step explanation:
To find an exact value for Cos75°, we use the compound angle formula. Since 75° = 45° + 30°, Cos75° = Cos(45° + 30°).
Using Cos(A + B) = CosACosB - SinASinB where A = 45° and B = 30°,
Cos75° = Cos(45° + 30°) = Cos45°Cos30° - Sin45°Sin30°
Now Cos45° = Sin45° = 1/√2 = √2/2, Cos30° = √3/2 and Sin30° = 1/2.
Substituting these values into the above equation, we have
Cos75° = Cos(45° + 30°)
= Cos45°Cos30° - Sin45°Sin30°
= √2/2 × √3/2 - √2/2 × 1/2
= √6/4 -√2/4
= √2(√3 - 1)/4

Angle Theorems for triangles
Answer:
Step-by-step explanation:
The interior angles of a triangle add to 180°:a + b + c = 180°
Angles c and d make a straight angle, which is 180°:d + c = 180°
So d + c equals a + b + c:d + c = a + b + c.
Subtract c from both sides:d = a + b.
I need help with linear regression
Answer:
In statistics, linear regression is a linear approach to modelling the relationship between a scalar response (or dependent variable) and one or more explanatory variables (or independent variables). The case of one explanatory variable is called simple linear regression. For more than one explanatory variable, the process is called multiple linear regression. This term is distinct from multivariate linear regression, where multiple correlated dependent variables are predicted, rather than a single scalar variable.
XYZ shown below has a measure of (8x + 12)°. The measure of 1 is (4x + 8)°, and the measure of 2 is (9x - 11).
What is the measure of ZXYZ?
A 3
B 20°
C 36°
D 60
Answer:
C
Step-by-step explanation:
∠ XYZ = ∠ 1 + ∠ 2, substitute values
8x + 12 = 4x + 8 + 9x - 11 = 13x - 3 ( subtract 13x from both sides )
- 5x + 12 = - 3 ( subtract 12 from both sides )
- 5x = - 15 ( divide both sides by - 5 )
x = 3
Thus
∠ XYZ = 8x + 12 = 8(3) + 12 = 24 + 12 = 36° → C

HELP PLEASE
Answer:
The points that lie in the solution set of following system of inequalities are:
Option A (1,-5) and Option C (5,1)
Step-by-step explanation:
We need to find the points that lie in the solution set to the following system of inequalities
[tex]y<-3x+3\\y<x+2[/tex]
We will check each option to identify if they satisfy the given set of inequalities or net.
Option A (1,-5)
We have x=1, y=-5
Putting values and checking
[tex]\\y<-3x+3\\-5<-3(1)+3\\-5<0 \ (true)\\y<x+2\\-5<1+2\\-5<3 \ (true)[/tex]
So, Option A is correct as both values satisfy the given set of equations
Option B (1,5)
We have x=1, y=5
Putting values and checking
[tex]y<-3x+3\\5<-3(1)+3\\5<0 \ (false)\\y<x+2\\5<1+2\\5<3 \ (false)[/tex]
So, Option B is not correct as both values doesn't satisfy the given set of equations
Option C (5,1)
We have x=5, y=1
Putting values and checking
[tex]y<-3x+3\\1<-3(5)+3\\1<-15+3\\1<12 \ (true)\\y<x+2\\1<5+2\\1<7 \ (true)[/tex]
So, Option C is correct as both values satisfy the given set of equations
Option D (-1,5)
We have x=-1, y=5
putting values and checking
[tex]y<-3x+3\\5<-3(-1)+2\\5<3+2\\5<5 \ (false)\\y<x+2\\5<-1+2\\5<-1 \ (false)[/tex]
So, Option D is not correct as both values doesn't satisfy the given set of equations

A book weighs 0.65 kg. A printing company packs 5 copies of
the book in a box. How much do the books in the box weigh?
Answer:
3.25 kg
Step-by-step explanation:
Since there are five books in the box, and one book weighs 0.65 kg, you just have to multiply 0.65 by five.
0.65(5)=3.25. So the answer is 3.25kg
Which statements about the Commutative Property of Multiplication are TRUE? Select all that apply. A. The property applies to all real numbers. B. The property states that ab is equivalent to ba. a ( x + y ) = ax + ay C. There is also a Commutative Property of Division because multiplication and division are related operations. D. The property states that when multiplying three numbers together, you can multiply any two of them first and then multiply by the remaining number.
Answer:
b) The property states that ab is equivalent to b a
Step-by-step explanation:
Commutative property:-
the commutative property , when we multiply two integers , the answer we get after multiplication will remain the same, even if the position of the integers are interchanged.
Let 'a' and 'b' be the two integers , then ab = b a
Example:-
. 1 X 2 = 2 X 1 = 2
. 12 X 5 = 5 X 12 = 60

-4x = 22
Answer:
x=-5.5
Step-by-step explanation:
This equation has already been simplified to the last part for you so all you have to do is divide 22 by -4 and you get -5.5
22/-4=-5.5
Answer:
x = -5.5
Step-by-step explanation:
To answer this you need to isolate the x.. So -4x/-4 and then do the same to 22. So 22/-4 = -5.5
The answer is x = -5.5
