How are the measures of angles, arcs and segments formed by secant lines that intersect within a circle related?
Answer:
The answers below ._.
Step-by-step explanation:
A secant is a line that intersects a circle in exactly two points. When a tangent and a secant, two secants, or two tangents intersect outside a circle then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs.
The formation of secant lines that intersect within a circle is related when a secant and a tangent or two tangents intersect each other outside a circle.
What is a secant line?A secant line is a straight line that connects two points on a curve. The secant line approaches a tangent line when the two points are drawn together.
So, If a tangent and a secant, or two tangents intersect at the exterior side of a circle, the angle created has a measure equal to one-half the positive difference between the intercepted arcs' measures.

One number is six less than a second number. Six times the first is 8 more than 4 times the second. Find the numbers.
To find the values of the two numbers, we can set up a system of equations based on the given information and then solve for x and y. The first number is 16 and the second number is 22.
Explanation:Let's represent the first number as x and the second number as y.
We can set up two equations based on the given information.
The first equation is: x = y - 6
The second equation is: 6x = 4y + 8
Now we can solve this system of equations to find the values of x and y.
Substituting the first equation into the second equation, we get: 6(y - 6) = 4y + 8
Simplifying, we get: 6y - 36 = 4y + 8
Bringing like terms together, we have: 6y - 4y = 8 + 36
Combining like terms, we get: 2y = 44
Dividing both sides by 2, we have: y = 22
Now substitute y = 22 back into the first equation: x = 22 - 6
Simplifying, we get: x = 16
Therefore, the first number is 16 and the second number is 22.

one length of a swimming pool is 25m Alison swims 60 lengths of the pool. how many more lengths must Alison swim to complete 1 mile?
hint= 1 mile is 1.6km
Answer:
4
Step-by-step explanation:
1 mile = 1.6 km
1 km = 1000 m
1.6 * 1000 = 1600, So to swim 1 mile, she must swim 1600 m
She has already swam 60 lengths which is 1500 m because 60 (the number of lengths)*25 (the length of the pool) = 1500.
1600 (the amount she needs to swim) - 1500 (the amount she has already swam) = 100.
She needs to swim 100 m more, which is 4 lengths because 100/25 = 4.
In the right triangle shown, DF=EF=3DF=EF=3D, F, equals, E, F, equals, 3.
How long is DEDED, E?
The length of side DE in the right triangle shown is 4.24 units.
We can use the Pythagorean Theorem to solve for the length of DE, since we know the lengths of the other two sides.
The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
The hypotenuse of the triangle is DE, and the other two sides are DF and EF. We know that DF = EF = 3 units. Therefore, we can set up the following equation:
[tex]DE^2 = DF^2 + EF^2[/tex]
Substituting in the known values, we get:
[tex]DE^2 = 3^2 + 3^2[/tex]
[tex]DE^2 = 9 + 9[/tex]
[tex]DE^2 = 18[/tex]
Taking the square root of both sides, we get the length of DE:
DE = √18
DE ≈ 4.24 units
Therefore, the length of side DE in the right triangle shown is 4.24 units.

There are 250 economy class seats on board. The airline sells some economy class seats at a discount price of $440 in advance and reserve a number of seats to sell at the full price of $770. Suppose that Dallas One Airline can always sell all discount tickets, and the demand for full price tickets is normally distributed with a mean of 100 and a standard deviation of 25. What is the probability that there will be no empty seat when the Dallas One Airline uses the optimal protection level? Choose the closest number.
Answer:
Check the explanation
Step-by-step explanation:
Cost of over reserving full cost tickets, Co = $440 ( empty seats as we cannot get even the discounted revenue)
Cost of under reserving Cu = 770-440 = $330 ( because you sell more discounted tickets)
Now critical ratio = Cu / (Cu+Co) = 330/770 = 0.42857
Now for above critical ratio ,z = -0.18 ( refer standard normal distribution table)
Optimal protection level = mean +z*standard deviation = 100-0.18*25 = 95.5 = 96
The possible costs include: all the above. You may need to provide compensation to passenger and make alternative travel arrangements. Also passenger won't be happy by over booking and their will be loss of good will.
All members of our painting team paint at the same rate. If 20 members can paint a 4800 square foot wall in 36 minutes, then how long would it take for 9 members to paint a 4200 square-foot wall, in minutes?
Answer:
70 minutes
Step-by-step explanation:
We assume that the time is proportional to the area and inversely proportional to the number of members.
Then the time for the second job will be the first job's time multiplied by ...
20/9 . . . the inverse of the ratio of members painting
4200/4800 = 7/8 . . . the ratio of area being painted
The time it would take is ...

Historically, a certain region has experienced 92 thunder days annually. (A "thunder day" is day on which at least one instance of thunder is audible to a normal human ear). Over the past fifteen years, the mean number of thunder days is 72 with a standard deviation of 38. Can you conclude that the mean number of thunder days is less than 92? Use the level of significance.
Answer:
We conclude that the mean number of thunder days is less than 92.
Step-by-step explanation:
We are given that Historically, a certain region has experienced 92 thunder days annually.
Over the past fifteen years, the mean number of thunder days is 72 with a standard deviation of 38.
Let [tex]\mu[/tex] = mean number of thunder days.
So, Null Hypothesis, [tex]H_0[/tex] : [tex]\mu \geq[/tex] 92 days {means that the mean number of thunder days is more than or equal to 92}
Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu[/tex] < 92 days {means that the mean number of thunder days is less than 92}
The test statistics that would be used here One-sample t test statistics as we don't know about the population standard deviation;
T.S. = [tex]\frac{\bar X-\mu}{\frac{s}{\sqrt{n} } }[/tex] ~ [tex]t_n_-_1[/tex]
where, [tex]\bar X[/tex] = sample mean number of thunder days = 72
s = sample standard deviation = 38
n = sample of years = 15
So, test statistics = [tex]\frac{72-92}{\frac{38}{\sqrt{15} } }[/tex] ~ [tex]t_1_4[/tex]
= -2.038
The value of z test statistics is -2.038.
Since, in the question we are not given with the level of significance so we assume it to be 5%. Now, at 5% significance level the t table gives critical value of -1.761 at 14 degree of freedom for left-tailed test.
Since our test statistics is less than the critical value of t as -2.038 < -1.761, so we have sufficient evidence to reject our null hypothesis as it will fall in the rejection region due to which we reject our null hypothesis.
Therefore, we conclude that the mean number of thunder days is less than 92.

Step-by-step explanation:
A state Department of Transportation claims that the mean wait time for various services at its different locations is at most 6 minutes. A random sample of 34 services at different locations has a mean wait time of 10.3 minutes and a standard deviation of 8.0 minutes. Is there enough evidence to reject the claim at alpha equals 0.01? Find the critical value. Round your answer to the thousandths place.
To determine whether there is enough evidence to reject the claim of the state Department of Transportation, a hypothesis test needs to be performed. The null hypothesis (H0) is that the mean wait time is 6 minutes or less, while the alternative hypothesis (H1) is that the mean wait time is greater than 6 minutes. Using a one-sample t-test, the test statistic is calculated and compared to the critical value obtained from the t-distribution table or calculator. In this case, the test statistic is greater than the critical value, indicating that there is enough evidence to reject the null hypothesis.
Explanation:To determine whether there is enough evidence to reject the claim of the state Department of Transportation, we need to perform a hypothesis test.
Hypotheses:
Let:
μ be the mean wait time for various services at different locations.
The null hypothesis (H0) is that the mean wait time (μ) is 6 minutes or less:
H0: μ ≤ 6
The alternative hypothesis (H1) is that the mean wait time (μ) is greater than 6 minutes:
H1: μ > 6
Test statistic:
We will use a one-sample t-test since the population standard deviation is unknown.
The test statistic (t) is calculated using the formula:
t = (Xbar - μ)/(s/√(n))
Where:
Xbar is the sample mean - 10.3 minutes,
μ is the claimed mean - 6 minutes,
s is the sample standard deviation - 8.0 minutes, and
n is the sample size - 34.
Critical value:
To find the critical value, we need to determine the rejection region using the significance level (alpha) of 0.01 and the degrees of freedom (df) which is n - 1 = 33.
From the t-distribution table or calculator, the critical value for a one-tailed test at alpha = 0.01 and df = 33 is approximately 2.449.
Conclusion:
The test statistic (t) = (10.3 - 6)/(8.0/√(34)) = 3.720.
Since the test statistic (t) = 3.720 > 2.449 (the critical value), we have enough evidence to reject the null hypothesis.
Therefore, we can conclude that there is sufficient evidence to reject the claim of the state Department of Transportation at alpha = 0.01.
