Arc length formula:
s = 2 π r (θ/360°)Substitute values:
s = 2*3.14*15(80/360) = 20.93 inA number is chosen at random from 1 to 25. Find the probability of selecting an odd number or multiples of 5. *
Answer:
Odd number: 13/25 (52%)
Multiples of 5: 5/25 (20%)
Step-by-step explanation:
There are 13 odd numbers between 1 and 25 so you have a 13/25 chance which is 52% (13/25 = 0.52). There are 5 multiples of 2 between 1 and 25 so you have a 5/25 chance which is 20% (5/25 = 0.2).
The probability of selecting an odd number or multiples of 5 is 3/5
What is probability?"It is finding out the possibilities of the occurrence of an event."
Formula to find the probability of an event:"P(A) = n(A) / n(S)
where, n(A) is the number of favorable outcomes of an event A
n(S) is the total number of outcomes for an experiment"
For given question,
A number is chosen at random from 1 to 25.
n(S) = 25
Let event A: selecting odd number
⇒ A = {1 , 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25}
⇒ n(A) = 13
So, the probability of selecting odd number would be,
⇒ P(A) = n(A)/n(S)
⇒ P(A) = 13/25
Let event B: selecting a number which is multiple of 5
⇒ B ={5, 10, 15, 20, 25}
⇒ n(B) = 5
So, the probability of selecting a number which is multiple of 5 would be,
⇒ P(B) = n(B)/n(S)
⇒ P(B) = 5/25
Let (A ∩ B) represents the odd numbers which are multiple of 5
⇒ (A ∩ B) = {5, 15, 25}
⇒ n(A ∩ B) = 3
So, the probability of selecting odd numbers which are multiple of 5 would be,
⇒ P(A ∩ B) = n(A ∩ B)/n(S)
⇒ P(A ∩ B) = 3/25
So, the probability of selecting an odd number or multiples of 5 is,
⇒ P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
⇒ P(A ∪ B) = 13/25 + 5/25 - 3/25
⇒ P(A ∪ B) = 15/25
⇒ P(A ∪ B) = 3/5
Therefore, the probability of selecting an odd number or multiples of 5 is 3/5

What is an equation of the line that passes through the points (-6, -2) and
(-3, 2)? Put your answer in fully reduced form.
Answer:
The equation of line is: [tex]\mathbf{4x-3y=-18}[/tex]
Step-by-step explanation:
We need to find an equation of the line that passes through the points (-6, -2) and (-3, 2)?
The equation of line in slope-intercept form is: [tex]y=mx+b[/tex]
where m is slope and b is y-intercept.
We need to find slope and y-intercept.
Finding Slope
Slope can be found using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have [tex]x_1=-6,y_1=-2, x_2=-3, y_2=2[/tex]
Putting values and finding slope
[tex]Slope=\frac{2-(-2)}{-3-(-6)}\\Slope=\frac{2+2}{-3+6} \\Slope=\frac{4}{3}[/tex]
So, we get slope: [tex]m=\frac{4}{3}[/tex]
Finding y-intercept
Using point (-6,-2) and slope [tex]m=\frac{4}{3}[/tex] we can find y-intercept
[tex]y=mx+b\\-2=\frac{4}{3}(-6)+b\\-2=4(-2)+b\\-2=-8+b\\b=-2+8\\b=6[/tex]
So, we get y-intercept b= 6
Equation of required line
The equation of required line having slope [tex]m=\frac{4}{3}[/tex] and y-intercept b = 6 is
[tex]y=mx+b\\y=\frac{4}{3}x+6[/tex]
Now transforming in fully reduced form:
[tex]y=\frac{4x+6*3}{3} \\y=\frac{4x+18}{3} \\3y=4x+18\\4x-3y=-18[/tex]
So, the equation of line is: [tex]\mathbf{4x-3y=-18}[/tex]

In DCAB, If DB=38, What is DC? 38 45 52 112
Answer:
C. 52°
Step-by-step explanation:
In ∆CAB, m<A = right angle = 90°
m<B = 38°
m<C + m<A + m<B = 180° (sum of ∆)
m<C + 90° + 38° = 180° (substitution)
m<C + 128 = 180
m<C = 180 - 128 (subtraction property of equality)
m<C = 52°

162 divided by 4.1 estimate
Answer:
40
Step-by-step explanation:
162/4.1= 39.51 round to 40
The solution of the equation after dividing would be 40.
Used the concept of the divide that states,
The division method is used to distribute a group of things into equal parts. The division is just the opposite of multiplications.
Given that,
162 divided by 4.1
Now divide the numbers,
162 divided by 4.1
It can be written as,
162 ÷ 4.1
162 / 4.1
1620/41
This gives,
39.512
Rounded to whole numbers,
40
Therefore, the solution is 40.

In science class, Vicky did an experiment with an unknown solid. She started with 11 grams of the solid. During the experiment, the change in the mass of the solid was –4 grams. What was the final mass of the solid To solve the problem, Jamal subtracted 11–(–4) and came up with an answer of 15 grams. Is Jamal correct? Why or why not?
Step-by-step explanation:
In this following excerpt,
We know that jamal wants to know the final mass, for this to be solved. We have to add the initial mass (11) to the change in the mass i.e, [-4] for this to be qualified as the final mass we are supposed to add the 11 to the -4, i.e, (11+(-4).)
Answer:
All in all the statement to support this resolution is,
11 + (-4)

The area
The area of a triangle ABC is 64 cm². Given AB = 11 cm and BC = 15 cm, Find ABC. Trying to find angle B.
Answer:
∠B ≈ 50.9°
Step-by-step explanation:
The area formula for a triangle can be used to find the missing angle.
Area formulaWe don't want confusion between A for area and angle A, so we define Q as the area of the triangle with sides a, c, and included angle B. In this scenario, 'a' represents side BC (opposite angle A), and 'c' represents side AB (opposite angle C).
Q = (1/2)ac·sin(B)
Unknown angleSolving for B, we have ...
2Q/(ac) = sin(B)
B = arcsin(2Q/(ac)
B = arcsin(2(64)/(11(15)) = arcsin(128/165)
∠B ≈ 50.9°

guys I need help with both of the questions
half of the substance to remain is called the half-life of the substance.
The half-life of a pesticide is 10 years. A farmer initially applies 200 grams of the
pesticide to a fence post.
Complete the following statements.
After 20 years, there are
grams of pesticide left. Round your answer
to the nearest whole gram.
After 60 years, there are
grams of pesticide left. Round your answer
to the nearest hundredth of a gram.
After
years, there are approximately 1.03 grams of pesticide
left. Round your answer to the nearest whole year.
Answer:
Instructions are below.
Step-by-step explanation:
To calculate the final amount of a given substance, we need to use the following formula:
final amount= initial amount / (2^n)
n= elapsed time / half-life
For 20 years:
n= 20/10= 2
Final amount= 200/(2^2)
Final amount= 50 grams
For 60 years:
n= 60/10= 6
Final amount= 200/ (2^6)
Final amount= 3.125 grams
To calculate the elapsed time it is more complicated:
elapsed time= ln(ending amount/beginning amount) / (-decay constant)
ln= natural logarithm
decay constant= ln(2) / half-life
decay constant= 0.0693
elapsed time= ln(1.03/200) / (-0.0693)
elapsed time= 76.028
Prove:
n= 76.02/10= 7.602
Final amount= 200/(2^7.602)= 1.03 grams
