See Explanation Below
Step-by-step explanation:
Given
Total Sweets = 10
Red = 4
Green = 2
Yellow = 3
Purple = 1
Required
a & b
The question is not properly presented; however the solution is as follows;
A.
Let P(Yellow) represent the probability of selecting a yellow sweet and n(Yellow) represent the number of Yellow sweets;
[tex]P(Yellow) = \frac{n(Yellow)}{Total}[/tex]
[tex]P(Yellow) = \frac{4}{10}[/tex]
[tex]P(Yellow) = 0.4[/tex]
So, whichever letter that shows [tex]0.4[/tex] or [tex]\frac{4}{10}[/tex] is the probability of choosing a yellow sweet
B.
Let P(Orange) represent the probability of selecting an orange sweet and n(Orange) represent the number of orange sweets;
Since, there's no orange sweet in the bag;
[tex]n(Orange) = 0[/tex]
[tex]P(Orange) = \frac{n(Orange)}{Total}[/tex]
[tex]P(Orange) = \frac{0}{10}[/tex]
[tex]P(Orange) = 0[/tex]
In probability; opposite probabilities add up to 1;
Let P(Not\ Orange) represent the probability of choosing a sweet that is not orange
[tex]P(Not\ Orange) + P(Orange) = 1[/tex]
Substitute [tex]P(Orange) = 0[/tex]
[tex]P(Not\ Orange) + 0 = 1[/tex]
[tex]P(Not\ Orange) = 1[/tex]
So, whichever letter that shows 0 is the probability of choosing a sweet that is not orange

Whoever answers this fully will get brainliest. Part A: Using the graph above, create a system of inequalities that only contains points C and F in the overlapping shaded regions. Explain how the lines will be graphed and shaded on the coordinate grid above. Part B: Explain how to verify that the points C and F are solutions to the system of inequalities created in Part A. Part C: Chickens can only be raised in the area defined by y > −4x + 3. Explain how you can identify farms in which chickens can be raised.
Answer:
Step-by-step explanation:
a. the inequality is x+y >= 2 (red line) that keeps onlythe two farms in the region.
b. substituting the coordinates of the farms in the inequality and see if they are satisfied:
C(2,2) 2+2 = 4 > 2 checks
F(3,4) 3+4 = 7 > 2 checks.
The other farms will not , for example,
D(1,-2) 1-2 = -1 < 2 does not check.
...
c. y > -4x + 3 is shown in blue.
Farms that satisfy given inequality can raise chickens, i.e. to the right of the blue line, or farms C,E and F.
If necessary, we can again check by the coordinates as in part b.
C(2,2) -4(2) + 2 = -8+2 = -6 y=2 > -6, so checks.

Answer:
The lines are NOT perpendicular because the slopes are not negative reciprocals.
Step-by-step explanation:
For two lines to be parallel, they must have the same slopes. For two lines to be perpendicular, they must be negative reciprocals.
In this case, the two slopes are simply reciprocals; they are not negative reciprocals. And so, the lines are NOT perpendicular because the slopes are not negative reciprocals.

pls hurry the answer is not 36.......Given a * b=ba−ba+ab, find (2*3)×(3*2).
Answer:
36
Step-by-step explanation:
In the above question, we have been given a rule to follow
Given a * b = ba−ba+ab
We are to find (2*3)×(3*2)
Let simplify each bracket first
a * b = ba−ba+ab
2*3, a = 2, b = 3
2*3 = 3×2 - 3×2 + 2×3
= 6 - 6 + 6
= 6
a * b = ba−ba+ab
3*2, a = 3, b = 2
3*2 = 2×3 - 2×3 + 3×2
= 6 - 6 + 6
= 6
(2*3)×(3*2)
= 6 × 6
= 36
The answer is 36

The corners of a square are cut off two centimeters from each corner to form an octagon. If the octagon is 10 centimeters wide, what is its area?
Answer:
Step-by-step explanation:
Area of octagon = area of square - area of 4 triangles that are formed in four corners
Area of square:
Side = Width of the octagon = 10 cm
Area = side * side
= 10 * 10
= 100 cm²
Area of triangle:
Base = 2cm
height = 2 cm
Area =[tex]\frac{1}{2}b*h[/tex]
=[tex]\frac{1}{2}*2*2[/tex]
= 2 cm²
Area of octagon = 100 - 2 = 98 cm²
Write the interval {x|1 < x < 3} as an i inequality
and using interval notation.
Answer:
1 < x < 3
(1 , 3)
Step-by-step explanation:
We have been provided with a set that is
{x|1 < x < 3}
We have to write it in both as an inequality and also in the form of interval notation.
The inequality can be found easily by just looking at the given set. It states that the set contains x, such that x is greater than 1 and x is smaller than 3, so the inequality can be written as:
1 < x < 3
To write in interval notation, we use brackets, As both 1 and 3 are not included, we'll use round brackets to show the interval.

O A.3
O B.4
O C.5
O D.8
Answer:
A. 3
Step-by-step explanation:
Let the integers be
x
(x+1)
(x+2)
(x+3)
Sum the integers
We have,
x+(x+1)+(x+2)+(x+3)=18
x+x+1+x+2+x+3=18
4x+6=18
Subtract 6 from both sides
4x-6=18-6
4x=12
Divide both sides by 4
4x/4=12/4
x=3
The smallest integer which is x is equal to 3
Check:
3+4+5+6=18

x + 12 < 15 Subtracted 3x from both sides
x < 3 Subtracted 12 from both sides
Answer:
4x^2+9x-15<0
Step-by-step explanation:
x.4(x+3)<3(x+5)
(4x)(x+3)<3x+3x5
(4x)(x+3)<3x+15
4xx+4x.3<3x+15
4x^1+1+4x3x<3x+15
4x^2+12x<3x+15
(4x^2+12x)+(-3x-15)<(3x+15)+(-3x-15x)
4x^2+9x-15<3x-3x+15-15
4x^2+9x-15<0

the circle.
AOC is a straight line.
Angle BAO is 24° and Angle ADO is 42°
a)find angle CAD
b)find the size of ACB
c)find the size of angle BCD
Answer:
Step-by-step explanation:
a) angle CAD= angle ODA ( in triangle OAD, OA=OD(same radius) angels opp to equal sides are equal)
hence angle CAD=42
b)angle b =90(angle subtended by diameter)
hence using angle sum property in triABC,
angle ACB=66-------------eq4
c) in tri OAD,
Angle AOD=180-(42+42)-------(using angle sum prop.)
=> 96-----------------eq1
angleACD=1/2 Angle AOD ( angle subtende by an arc at centre is double the angle subtended...)
hence angle ACD =1/2 x 96(from eq1)
angleACD=48--------------eq3
from eq 3,and eq4,
angle BCD= 48+66
=114 degree...
hope this helped you........pls mark brainliest
a) Measure of angle CAD is, 42°
b) The size of ACB is, 66°
c) The size of angle BCD is, 114°
What is Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Given that;
In the diagram O is the center of the circle.
And, AOC is a straight line.
Here, Angle BAO is 24° and Angle ADO is 42°.
Now,
a) In triangle OAD,
⇒ OA=OD (same radius)
And, Angels opposite to equal sides are equal.
Hence, We get;
⇒ ∠CAD= ∠ODA
⇒ ∠ CAD = 42°
b) We have;
⇒ ∠B =90 (Angle subtended by diameter)
Hence, By using angle sum property in ΔABC,
⇒ ∠ BAC + ∠ACB + ∠B = 180°
⇒ 24 + ∠ACB + 90° = 180°
⇒ ∠ ACB = 66°
c) In ΔOAD,
⇒ ∠AOD = 180 - (42 + 42) ( By using angle sum property)
= 96
And, Angle subtended by an arc at center is double the angle subtended.
Hence, We get;
⇒ ∠ACD = 1/2 ∠AOD
= 1/2 × 96
= 48°
Hence, We get;
⇒ ∠ BCD = 48° + 66°
= 114°

A coordinate plane with 2 lines drawn. The first line is labeled f(x) and passes through the points (0, negative 2) and (1, 1). The second line is labeled g(x) and passes through the points (negative 4, 0) and (0, 2). The lines intersect at about (2.5, 3.2) How does the slope of g(x) compare to the slope of f(x)? The slope of g(x) is the opposite of the slope of f(x). The slope of g(x) is less than the slope of f(x). The slope of g(x) is greater than the slope of f(x). The slope of g(x) is equal to the slope of f(x). ALSO ITS NOT A NUMBER ANSWER
Answer:
Option B.
Step-by-step explanation:
If a line passing through two points, then the slope of line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given that f(x) passing through the points (0,-2) and (1,1). So, slope of f(x) is
[tex]m_1=\dfrac{1-(-2)}{1-0}=1+2=3[/tex]
It is given that g(x) passing through the points (-4,0) and (0,2). So, slope of g(x) is
[tex]m_2=\dfrac{2-0}{0-(-4)}=\dfrac{2}{4}=\dfrac{1}{2}[/tex]
Since, [tex]\dfrac{1}{2}<3[/tex], therefore [tex]m_2<m_1[/tex].
The slope of g(x) is less than the slope of f(x).
Therefore, the correct option is B.

Answer:
look below
Step-by-step explanation:
The equation of graph g(x) = f(-x) as it has been rotated along y-axis and the maximum coordinates of g(x) is (-3, 4).
What is a function?A function can be thought of as output for the given set of inputs. The output is called the dependent variable and the inputs are called the independent variable.
We know when we rotate a function along the y-axis sign of x changes.
Given a function y = f(x) after rotation along y-axis it becomes y = f(-x) = g(x)
and if the given function is odd f(-x) becomes -f(x).
Also given that the maximum point of f(x) = (3, 4).
∴ Function g(x) will have maximum at coordinates (-3, 4).
