Answer:
see explanation
Step-by-step explanation:
a + b + c = 180 ( sum of angles in a triangle )
c + d = 180 ( adjacent angles are supplementary ), thus
a + b + c = c + d ( subtract c from both sides )
a + b = d
The reason for the value of a+b being equal to d is because adjacent angles are supplementary.
First and foremost, it should be noted that a triangle has three sides and the sum of the angles in the triangle will be equal to 180°.
Therefore, based on the information given in the question, the solution will go thus:
a + b + c = 180°
Note that c + d = 180° since adjacent angles are supplementary.
Therefore, a + b + c = c + d
Collect like terms
a + b + c - c = d
a + b = d
Therefore, the equation has been proven and showed that a + b = d.

When studying radioactive material, a nuclear engineer found that over 365 days, 1,000,000 radioactive atoms decayed to 974,728 radioactive atoms, so 25,272 atoms decayed during 365 days a. Find the mean number of radioactive atoms that decayed in a day b. Find the probability that on a given day, 50 radioactive atoms decayed
a) The mean number of radioactive atoms that decayed in a day is approximately 69.28 atoms. and b) the probability that on a given day, 50 radioactive atoms decayed is approximately 2.314685e-47.
a. To find the mean number of radioactive atoms that decayed in a day, we can divide the total number of atoms decayed over 365 days by the number of days:
Mean number of radioactive atoms decayed per day = Number of atoms decayed / Number of days
Mean number of radioactive atoms decayed per day = 25,272 atoms / 365 days
Mean number of radioactive atoms decayed per day ≈ 69.28 atoms
Therefore, the mean number of radioactive atoms that decayed in a day is approximately 69.28 atoms.
b. To find the probability that on a given day, 50 radioactive atoms decayed, we can use the Poisson distribution. The Poisson distribution is often used to model the number of events occurring in a fixed interval of time or space.
The formula for the Poisson distribution is:
P(X = k) = [tex](e^(-λ) * λ^k) / k![/tex]
Where:
P(X = k) is the probability that k events occur,
e is Euler's number, approximately 2.71828,
λ is the average number of events occurring in the given interval,
k is the number of events we are interested in.
In this case, the average number of radioactive atoms decayed in a day is approximately 69.28 atoms (calculated in part a). Therefore, λ = 69.28.
Substituting the values into the Poisson distribution formula:
P(X = 50) =[tex](e^(-69.28) * 69.28^50)[/tex] / 50!
Calculating [tex]e^(-69.28):[/tex]
[tex]e^(-69.28)[/tex] ≈ 2.67048178576e-31
Calculating [tex]69.28^50:[/tex]
[tex]69.28^50[/tex] ≈ 2.64267020807e+80
Calculating 50! (factorial of 50):
50! ≈ 3.04140932017e+64
Substituting these values back into the formula:
P(X = 50) ≈ (2.67048178576e-31 * 2.64267020807e+80) / 3.04140932017e+64
P(X = 50) ≈ 2.314685e-47
Therefore, the probability that on a given day, 50 radioactive atoms decayed is approximately 2.314685e-47.

Step-by-step explanation:
85 has the stem of 8.
The only leaf in stem 8 that has a number higher than the leaf 5 is 8.
The stem 9 is higher than the stem 8 so all of it's leaves are higher than 85.
There are 4 leaves under the stem 9 and there is one leaf in stem 8 that's higher than 5.

A vacation resort rents SCUBA equipment to certified divers. The resort charges an up-front fee of $25 and another fee of $12.50 an hour. What is the amount if you rent the SCUBA equipment for 1 hour and 15 minutes? • $40.63 $28.13 $50 $41
The amount for renting SCUBA equipment for 1 hour and 15 minutes is (1) $40.63, including an up-front fee of $25 and an hourly rate of $12.50.
To calculate the amount for renting SCUBA equipment for 1 hour and 15 minutes, we need to consider the up-front fee and the hourly rate.
The up-front fee is $25, which is a fixed cost.
The additional fee for each hour is $12.50. Since we have 1 hour and 15 minutes, we can consider it as 1.25 hours.
Therefore, the total cost can be calculated as:
Total cost = up-front fee + (hourly rate × number of hours)
Total cost = $25 + ($12.50 × 1.25)
Total cost = $25 + $15.63
Total cost = $40.63
Hence, the amount for renting the SCUBA equipment for 1 hour and 15 minutes is $40.63.
Therefore, the correct answer is: (1) $40.63

Let f(x)= ax^2+bx+c and g(x)= ax^2-bx+c. If f(1) = g(1)+2 and f(2)=2, find g(2).
Answer:
first lets calculate f(1)=g(1)+2
a+b+c=a-b+c+2 so b=1
next lets calculate f(2)=2 remembering that we found b=1
4a+2*1+c=2 so c=-4a
Now lets find g(2)
g(2)=4a-2b+c= -c-2+c=-2 this is the final response

pls help now plz On your own paper, please write a fraction with x^-5*y^4*z^18 in the numerator and x^-6*y^19*z^-2 in the denominator. Simplify this fraction.
Answer:
xz^20 / y^15
Step-by-step explanation:
x^-5*y^4*z^18
------------------------
x^-6*y^19*z^-2
We are dividing so we subtract the exponents
First simplify the x terms
x^ -5 / x^ -6 = x^( -5 - -6) = x^ (-5+6) = x
Then simplify the y terms
y^ 4 / y^ 19 = y^( 4 - 19) = y^ (-15)
Finally simplify the z terms
z^ 18 / z^ -2 = z^( 18 - -2) = z^ (18+2) = z^20
x y ^ -15 z^20
The positive exponent terms are in the numerator and the negative exponent terms are in the denominator ( they change to positive exponents)
xz^20 / y^15

A project has an initial cost of $40,400, expected net cash inflows of $14,000 per year for 9 years, and a cost of capital of 12%. What is the project's NPV? (Hint: Begin by constructing a time line.) Do not round your intermediate calculations. Round your answer to the nearest cent.
Answer:
$59,750
Step-by-step explanation:
According to the given situation, the calculation of net present value is shown below:-
Net present value = Net cash inflows × PVIFA factor(9,12%) - Initial cost
= $14,000 × 7.1607 - $40,400
= $100,250 - $40,500
= $59,750
Therefore as per the situation for computing the net present value we simply applied the above formula.
