m∠1 =
Answer:
I believe the answer is 103.
Step-by-step explanation:
Since line a is parallel to line b, angle m1 = angle m3.
Supposedly, angle m4 + angle m5 = 180 degrees, since it's a line. That also means that angle m3 + angle m4 = 180 degrees too.
That means:
angle m4 + angle m5 = angle m3 + angle m4
Subtract angle m4 from both sides of the equation.
You get,
angle m5 = angle m3.
Angle m5 is 103, and as we stated earlier, angle m3 = angle m1.
Thus, angle m1 = 103 degrees.
a. The probability of contracting a certain virus is 0.02. Find and evaluate numerically, the probability that at least 5 people in population of 200 get the virus.
b. The probability of having a certain gene is .25. Find the probability that in a population of 300, between 70 and 105 have the gene.
c. A fair die is rolled 19 times. Find the probability that the result is either 2 or 3 at least 6 and at most 10 times.
Using the binomial distribution, the probability of at least 5 people in a population of 200 getting a virus with a probability of 0.02 is 0.1237. The probability of between 70 and 105 people in a population of 300 having a gene with a probability of 0.25 is 0.9189. The probability of rolling a 2 or 3 at least 6 and at most 10 times in 19 rolls of a fair die is 0.0065.
This scenario follows a binomial distribution with n=200 and p=0.02, where n is the number of trials and p is the probability of success. We want to find the probability of at least 5 people getting the virus, which can be written as P(X≥5). Using the binomial probability formula, we get:
P(X≥5) = 1 - P(X<5) = 1 - P(X=0) - P(X=1) - P(X=2) - P(X=3) - P(X=4)
Using a binomial probability table or calculator, we can find the probabilities for each value of X:
P(X=0) = 0.9802, P(X=1) = 0.0392, P(X=2) = 0.0012, P(X=3) = 0.00003, P(X=4) = 0.0000006
Therefore,
P(X≥5) = 1 - (0.9802 + 0.0392 + 0.0012 + 0.00003 + 0.0000006) ≈ 0.038
So the probability that at least 5 people in a population of 200 get the virus is approximately 0.038.
This scenario follows a binomial distribution with n=300 and p=0.25. We want to find the probability that between 70 and 105 people have the gene, which can be written as:
P(70≤X≤105) = P(X≤105) - P(X<70)
Using a binomial probability table or calculator, we can find the probabilities for each value of X:
P(X<70) = 0.015, P(X≤105) = 0.999999999999997
Therefore,
P(70≤X≤105) = 0.999999999999997 - 0.015 ≈ 0.985
So the probability that between 70 and 105 people in a population of 300 have the gene is approximately 0.985.
This scenario follows a binomial distribution with n=19 and p=1/3, where p is the probability of getting either 2 or 3. We want to find the probability that the result is either 2 or 3 at least 6 and at most 10 times, which can be written as:
P(6≤X≤10) = P(X≤10) - P(X<6)
Using a binomial probability table or calculator, we can find the probabilities for each value of X:
P(X<6) = 0.778, P(X≤10) = 0.9999
Therefore,
P(6≤X≤10) = 0.9999 - 0.778 ≈ 0.221
So the probability that the result is either 2 or 3 at least 6 and at most 10 times in 19 rolls of a fair die is approximately 0.221.

Use the laplace transform to solve the given initial-value problem. y'' − 8y' 16y = t, y(0) = 0, y'(0) = 1
If the initial value problem is \(y^{11} -8y^{1} -15y=0\) and \(y^{1}(0) =1\),y(0)=0 then y(t)=\((e^{3t} -e^{5t} )/2\).
Given the initial value problem be \(y^{11} -8y^{1} -15y=0\)and \(y^{1}(0) =1\),y(0)=0.
We are required to find the solution of the given initial value problem.
Laplace transform is an integral transformation that converts a function of a real variable to a function of a complex variable.
Take laplace on the DE, we get
\(s^{2}-sY(0)-y^{i}(0)-8[sY(s)-y(0)-15Y(s)]=0\)
\(s^{2}Y(s)-s(0)-1-8{sY(s)-0)}+15Y(s)=0\)
(Putting the values given in question)
Y(s)=(\(s^{2} -8s+15)-1=0\)
Y(s)=1/(\(s^{2} -8s+15\))
Simplifying the above:
=1/(\(s^{2} -5s-3s+15)\)
=1/[s(s-5)-3(s-5)]
=1/2 [1/(s-3)-1/(s-5)]
Taking inverse of the above we get,
y(t)=\((e^{3t} -e^{5t} )/2\)
Hence if the initial value problem is \(y^{11} -8y^{1} -15y=0\) and \(y^{1}(0) =1\),y(0)=0 then y(t)=\((e^{3t} -e^{5t} )/2\).

The probability of picking the winning 4-digit number in a pick 4 lottery is 1/10,000.
explain what this probability means.
The probability of picking the winning 4-digit number in a pick 4 lottery being \(\frac{1}{10000}\) means that for every 10,000 possible number combinations, there is only one combination that will match the winning number.
In a pick 4 lottery, you need to select a 4-digit number out of the available options. The total number of possible combinations is determined by the number of digits and the range of values for each digit. In this case, there are 10 options (0-9) for each digit, resulting in a total of 10,000 possible combinations (\(10^4\)).
The probability of picking the winning number can be calculated by dividing the number of favorable outcomes (which is 1, as there is only one winning combination) by the total number of possible outcomes (which is 10,000). Therefore, the probability of selecting the winning 4-digit number is 1/10,000.
This probability indicates that out of every 10,000 tickets sold or number combinations played, statistically, only one of them will match the winning number. It highlights the rarity of winning the lottery and emphasizes the long odds involved. It's important to note that each individual ticket or number combination has the same probability of winning, regardless of previous outcomes or patterns.

You are purchasing a new car. In order to determine which car will provide maximum savings, you’ve researched miles per gallon (mpg) ratings of cars. If gas is $3.45 per gallon and you drive an average of 18,000 miles per year, the following rational equation is given:
d. The other car you are considering buying will get 33 mpg, but it costs $3000 more than the 27 mpg car. Would the additional savings in gas be worth the extra $3000 over a 5 year loan?
e. What gas mileage would your new car have to be if you saved $800 per year over your 18 mpg current car?
18000/x defines the gallons of the gas consumed by the old car in one year.
Step-by-step explanation:
If I purchase a car, I will definitely concentrate on a factor that is gas consumed by the car in a year.
As per statement given in the question if gas is $3.45 per gallon and I drive an average of 18000 miles per year.
If x miles per gallons is the average of the old car and y miles per gallons is the average of of new car.
Then total difference in gallons of the gas consumed by the old and new cars will be represented by the equation.
g(x) = 3.45 - 3.45
Here, 18000/x defines total number of gallons of the gas consumed by the old car in one year.
