Answer:
Probabilty[First and second fruit is peach without replacement] = 0.267 (Approx.)
Step-by-step explanation:
Given:
Number of oranges = 3
Number of peach = 8
Number of apple = 4
Find:
Probabilty[First and second fruit is peach without replacement]
Computation:
Probablity of an event = Number of favourable outcomes / Number of outcomes
Probabilty[First fruit is peach] = 8 / [3 + 8 + 4]
Probabilty[First fruit is peach] = 8 / 15
Probabilty[Second fruit is peach] = [8-1] / [3 + 8 + 4 - 1]
Probabilty[Second fruit is peach] = 7 / 14
Probabilty[Second fruit is peach] = 1 / 2
Probabilty[First and second fruit is peach without replacement] = Probabilty[First fruit is peach] x Probabilty[Second fruit is peach]
Probabilty[First and second fruit is peach without replacement] = [8/15][1/2]
Probabilty[First and second fruit is peach without replacement] = 8 / 30
Probabilty[First and second fruit is peach without replacement] = 0.267 (Approx.)
What is the value of X?
Answer:
x=20
Step-by-step explanation:
First, find LJ
Angle L = 60 (180 - 30 - 90)
The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.
cos(L)=adj/hyp
cos(60)=LJ/40√2
LJ = cos(60)*40√2
LJ = 20√2
Now you can use LJ to find x. You also know the value of each angle, 45
x=20√2⋅cos(45)
x=20
Alice draws a triangle and measures two of the angles with a protractor. The angle measures are 65 and 45. Cal says the measure of the third angle is 60. Explain why Cal's answer is incorrect.
Answer: Cal's answer must be incorrect because the sum of angles is incorrect.
Step-by-step explanation:
The sum of all interior angles of a triangle is 180 degrees.
According to Cal, the three angles of the triangle has magnitude 65, 45 and 60 respectively.
Sum of angles = 65+45+60
i.e. Sum of angles = 170 which is not equal to 180
Hence, Cal's answer must be incorrect because the sum of angles is incorrect.

Lauren is given a 12% pay rise.Her new salary is £24,080. What was Lauren's salary before the pay rise?
Answer:
The base salary was £21,500.
Step-by-step explanation:
Giving the following information:
Increase rate (g)= 12%
New salary= £24,080
To calculate the base salary, we need to use the following formula:
Base salary= new salary / (1 + increase rate)
Base salary= 24,080 / (1.12)
Base salary= £21,500
The base salary was £21,500.

In a bag, there are 8 blue marbles, 4 yellow marbles, and 6 red marbles. First question: What is the probability of not selecting a blue or yellow marble? Second question: What is the probability of first selecting a red marble, then selecting a yellow marble? Third question: What is the probability of first selecting a blue or yellow marble, replacing the marble, then selecting a red or blue marble?
Answer:
Question 1
P(not b or y) = P(r) = 6 / (8 + 4 + 6) = 6 / 18 = 1/3Question 2
Assumed no replacement here
P(r then y) = 6/18 * 4/17 = 4/51Question 3
P(b or y) = (8 + 4) / 18 = 12/18 = 2/3P(r or b) = (6 + 8)/18 = 14/18 = 7/9P(b or y then r or b) = 2/3*7/9 = 14/27Which statement is true about the local minimum of the graphed function?

What is the first step you will use to solve this equation:
4x +2 = 7x - 13
1. Subtract 2 from both sides of the equation
4x + 2 = 7x - 13
4x + 2 - 2 = 7x - 13 - 2
2. Simplify
4x + 2 - 2 = 7x - 13 - 2 -----> 4x = 7x - 13 - 2 -----> 4x = 7x - 15
3. Subtract 7x from both sides of the equation
4x = 7x - 15
4x - 7x = 7x - 15 - 7x
4. Simplify
4x - 7x = 7x - 15 - 7x -----> -3x = 7x - 15 - 7x -----> -3x = -15
5. Divide both sides of the equation by the same term
-3x = -15
-3x/-3 = -15/-3
6. Simplify
-3x/-3 = -15/-3
x = -15/-3
x = 5
7. Solution
x = 5

The perimeter, P, of a rectangle is equal to twice the sum of the length and width of the rectangle. Determine the width of a rectangle with a perimeter of 34 inches and a length of 5 inches. In your final answer, include all necessary calculations.
Answer:
12 inches
Step-by-step explanation:
5 + 5 = 10
34 - 10 = 24
24 ÷ 2 = 12
Therefore, the answer is 12 inches.
Find the value of x.
Answer:
x = 16
Step-by-step explanation:
Angles in a triangle add up to equal 180
Hence, 9x - 8 + x + 10 + x + 2 = 180
^ ( note that we just created an equation that we can use
to solve for x )
We now solve for x using the equation created.
9x - 8 + x + 10 + x + 2 = 180
step 1 combine like terms
9x + x + x = 11x
-8 + 10 + 2 = 4
we now have 11x + 4 = 180
step 2 subtract 4 from each side
180 - 4 = 176
4 - 4 cancels out
we now have 11x = 176
step 3 divide each side by 11
176 / 11= 16
11x / 11 = x
we're left with x = 16
5=97 find 2 and 4....................,,..,...
Answer:
∠ 2 = ∠ 4 = 83°
Step-by-step explanation:
∠ 2 and ∠ 5 are same- side interior angles and sum to 180° , that is
∠ 2 + 97° = 180° ( subtract 97° from both sides )
∠ 2 = 83°
∠ 2 and ∠ 4 are vertical angles and are congruent, then
∠ 4 = 83°
Tell whether the angles are complementary, supplementary, or neither.
Answer:they are supplementary

Draco and his friends bought Bertie Bott's Every Flavor Beans for $3 per packet and chocolate frogs for $1 per packet at Honeydukes. They spent a total of $54 to buy a total of 36 packets of Beans and frogs.
Part A: Write a system of equations that Draco can solve to find the number of packets of Bertie Bott's Every Flavor Beans and the number of packets of chocolate frogs that he and his friends bought at Honeydukes. Tell what the variables used in the equations represent. (5 points)
Part B: Solve the system of equations from Part A to find out how many packets of chocolate frogs and Bertie Bott's Every Flavor Beans Draco and his friends bought and write the answer in (x, y) form. Tell which method you used to get the answer, and explain why you selected that particular method to get the answer.
Answer:
Part A: x + y = 36, 3x + y = 54
Part B: (9, 27), I used subtraction to solve the system, because it eliminated the "y" value, so it would be easiest to solve.
Step-by-step explanation:
Amount of Bean Packets: x
Amount of Frogs: y
We are given that:
x + y = 36
3x + y = 54
This is the answer to answer A.
To solve, use subtraction. Subtract:
3x + y - (x + y) = 54 - 36
3x - x + y - y = 18
2x = 18
x = 9
Substituting x = 9 into x + y = 36, we find that y = 27
In (x, y) form, substitute x = 9 and y = 27 to get (9, 27)
I used subtraction to solve the system, because it eliminated the "y" value, so it would be easiest to solve.

SOOO in math class today we learned more about algebra such as
X + 10 = Y should I care??
Like srsly miss teacher ???

welp
that's lame!!
Hello there I hope you are having an great day :)
X + 10 = Y if you are trying to work out Y it would equal y = x + 10
If you are trying to work out X it would equal x = y − 10

In ΔDEF, the measure of ∠F=90°, EF = 2.3 feet, and FD = 2.9 feet. Find the measure of ∠D to the nearest tenth of a degree.
Answer:
[tex]\theta=38.42 \textdegree[/tex]
Step-by-step explanation:
From the question we are told that:
Angle of F [tex]\angle F=90 \textdegree[/tex]
Length of [tex]EF = 2.3 feet,[/tex]
Length of [tex]FD= 2.9 feet,[/tex]
Generally the equation for Angle D [tex]\theta[/tex] is mathematically given by
Since [tex]\angle F=90[/tex].The triangle is a right angle Triangle
Therefore
[tex]tan \theta=\frac{EF}{FD}[/tex]
[tex]tan \theta=\frac{2.3}{2.9}[/tex]
[tex]\theta=tan^{-1} 0.793[/tex]
[tex]\theta=38.42 \textdegree[/tex]
Una micra (μm) es una milésima de milímetro. Si la densidad del agua es 1000 kg/m³, ¿cuál es la masa de 10⁹ μm³ de agua?
Answer:
La masa de 10⁹ μm³ de agua es 1 mg.
Step-by-step explanation:
La densidad del agua es:
[tex] d = \frac{m}{V} = 1000 kg/m^{3} [/tex]
En donde:
m: es la masa =?
V: es el volumen = 10⁹ μm³
Para encontrar la masa de agua debemos convertir las unidades del volumen de μm³ a m³:
[tex]V = 10^{9} \mu m^{3}*\frac{1 m^{3}}{(10^{6} \mu m)^{3}} = 10^{-9} m^{3}[/tex]
Ahora, la masa es:
[tex]m = d*V = 1000 kg/m^{3}*10^{-9} m^{3} = 10^{-6} kg = 10^{-3} g = 1 mg[/tex]
Por lo tanto, la masa de 10⁹ μm³ de agua es 1 mg.

If the m∠1=123° m ∠ 1 = 123 ° and m∠2= (2x+7)° m ∠ 2 = ( 2 x + 7 ) ° , determine the value of x that supports l∥m l ∥ m . Show your work to support your answer.
Answer:
25
Step-by-step explanation:
Let us assume that m<1 nad m<2 are supplementary. Since the sum of supplementary angles is 180degrees, hence;
<1 + <2= 180
123+2x+7 = 180
130+2x = 180
2x = 180 - 130
2x = 50
x = 50/2
x = 25
Hence the value of x is 25

In circle E with m DEF 36 and DE = 3 units find area of
sector DEF. Round to the nearest hundredth.
E
Answer:
A ≈ 2.83 units²
Step-by-step explanation:
The area (A) of the sector is calculated as
A = area of circle × fraction of circle
= πr² × [tex]\frac{36}{360}[/tex]
= π × 3² × [tex]\frac{1}{10}[/tex]
= [tex]\frac{9\pi }{10}[/tex]
≈ 2.83 units² ( to the nearest hundredth )
