Answer: 110˚

Step-by-step explanation:

Complementary angles have a sum of 90˚

With this knowledge, we can say <B = 90 - <A = 90 - 20 = 70˚

Supplementary angles have a sum of 180˚

With this knowledge we can say <C = 180 - <B = 180 - 70 = 110˚

∴ Measure of angle C = 110˚

The equation will be:

t = b - 2

And we can see that:

Here we have two variables:

t = taner's age

b = age of Tanner's brother.

The independent variable is the one that does not depend on the other, in this case (for how it is worded) is the brother's age.

The dependent variable depends on the other, on this case, Tanner's age.

Now let's write the equation, we know that Taner's age is 2 years less than his brother, then:

t = b - 2

That is the equation.

Answer:

ASA

Step-by-step explanation:

There are two pairs of congruent angles, and the pair of congruent sides is included between the angles.

the number of different possible teams that can be formed is equal to nCr, or n!/(r!(n-r)!).

Assuming that the state narcotics bureau has more than 5 agents from which to choose, the number of different possible teams that can be formed is equal to the number of combinations of 5 agents out of the total number of agents the bureau has. This can be calculated using the formula nCr (n choose r), where n is the total number of agents and r is the number of agents in each team, which in this case is 5.

Therefore, the number of different possible teams that can be formed is equal to nCr, or n!/(r!(n-r)!).

In the similar triangle, x = 67.5 ft

Similar triangles are triangles in which the ratio of their sides are equal.

Given the similar triangles, ΔMNP and ΔMAB

By the ratio of similar triangles, we have that

MP/MN = MB/MA

We observe that MN = MA + AN

So, MA = MN - AN

So, MP/MN = MB/MA

MP/MN = MB/(MN - AN)

Given that

We have that

MP/MN = x/(MN - AN)

Making x subject of the formula, we have that

x = (MN - AN)MP/MN

So, substituting the values of the variables into the equation, we have that

x = (MN - AN)MP/MN

x = (71.5 ft - 22 ft)97.5 ft/71.5 ft

x = 49.5 ft × 97.5 ft/71.5 ft

x = 4826.25 ft²/71.5 ft

Step-by-step explanation:

The maximum number of hours is 1.6 hours and the minimum  number of hours is 1.6 hours.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Given that, a plane is flying at a speed of 175 miles per hour.

The distance covered by the pilot, d = 250 ± 25 miles

We know that, speed = Distance/Time

The equation for the maximum number of hours is given as;

175 =(250+25)/t

t=275/175

t=1.6 hours

The equation for the minimum number of hours is given as;

175 =(250-25)/t

175=225/t

t=225/175

t=1.3 hours

Therefore, the maximum number of hours is 1.6 hours and the minimum  number of hours is 1.6 hours.

The statement "sum of a and b integers is a negative integer" is true given that A and B are both negative integers and A is greater than B.

When we add two negative integers, the sum is always negative. This is because adding a negative number is the same as subtracting its absolute value. Therefore, if A and B are negative integers, then A + B will be negative as well.

Since A > B, the sum A + B will be closer in value to A than to B. However, it will still be negative because A and B are both negative integers.

So, the sum of A and B is a negative integer, and the statement is true.

Step-by-step explanation:

3 Cartons, divided by 5 people =

The probability that exactly 16 people out of 25 favor the new building project is 0.1285.

The probability that at most 16 people out of 25 favor the new building project is 0.3528.

The probability that between 12 and 19 (including 12 and 19) people out of 25 favor the new building project is 0.9088.

A binomial distribution is a probability distribution that describes the number of successes in a fixed number of trials, where each trial has two possible outcomes (success or failure) and the trials are independent.

The distribution of x, the number of people who favor the new building project when 25 people are chosen at random, can be modeled using a binomial distribution.

In this case, the probability of success (favoring the new building project) is 0.61, and the probability of failure (not favoring the project) is 0.39. The number of trials is 25, since we are choosing 25 people at random.

Thus, we can write x ~ Bin(25, 0.61), which means that x follows a binomial distribution with 25 trials and a probability of success of 0.61.

To find the probability that exactly 16 people out of 25 favor the new building project, we can use the binomial probability formula:

[tex]P(X = k) = (^n_k) * p^k * (1 - p)^{n - k}[/tex]

where X is the random variable (in this case, the number of people who favor the project), k is the number of successes we are interested in (in this case, 16), n is the number of trials (25), p is the probability of success (0.61), and (n choose k) is the binomial coefficient, which represents the number of ways to choose k successes out of n trials.

Plugging in the values, we get:

P(X = 16) = (25 choose 16) * 0.61¹⁶ * 0.39⁹ = 0.1285

Therefore, the probability that exactly 16 people out of 25 favor the new building project is 0.1285.

To find the probability that at least 16 people out of 25 favor the new building project, we need to add up the probabilities of all the events where the number of successes is 16 or greater. We can do this using the cumulative distribution function (CDF) of the binomial distribution, which gives us the probability of X being less than or equal to a certain value.

Using a calculator or a table, we can find that P(X ≥ 16) = 0.3528.

Therefore, the probability that at least 16 people out of 25 favor the new building project is 0.3528.

To find the probability that at most 16 people out of 25 favor the new building project, we can use the complement rule, which states that the probability of an event occurring is equal to 1 minus the probability of its complement (the event not occurring). In this case, the complement event is the number of people who favor the project being greater than 16.

Using the same CDF, we can find that P(X > 16) = 0.6472. Therefore,

P(X ≤ 16) = 1 - P(X > 16) = 1 - 0.6472 = 0.3528

We can do this using the binomial probability formula for each possible value of k, and then summing the results.

P(12 ≤ X ≤ 19) = P(X = 12) + P(X = 13) + ... + P(X = 19)

Using a calculator or a table, we can find the probabilities for each value of k, and then add them up:

P(12 ≤ X ≤ 19) = 0.0309 + 0.0746 + 0.1322 + 0.1821 + 0.2001 + 0.1821 + 0.1322 + 0.0746 = 0.9088

The x has a value of 36. The line's two points are (-12, 1) and (36, 7).

The slope of a line frequently represents the steepness and direction of the line. The slope of a straight line between the two locations, (x1,y1) and (x2,y2), can be easily determined by calculating the difference between their coordinates.

We can apply the slope formula to determine the value of x:

m is the slope and (x1, y1) and (x2, y2) are two points on the line, with m = (y2 - y1) / (x2 - x1).

We are given the point (x1, y1) = (-12, 1) and the slope m = 1/8. We are also given the y-coordinate of the other point as y2 = 7.

Plugging in the known values, we get:

1/8 = (7 - 1) / (x - (-12))

Simplifying and solving for x, we get:

1/8 = 6 / (x + 12)

1 = 48 / (x + 12)

x + 12 = 48

The probability of obtaining the same number of heads is 3/8 or 0.375 when each of two persons tosses three fair coins.

The probability that two persons will obtain the same number of heads depends on the number of possible combinations of heads and tails that can be obtained by each person.

Since each coin flip results in either a heads or tails, there are 2 possible outcomes for each flip. Therefore, for three coin flips,

there are 2^3 or 8 possible combinations of heads and tails.

Out of these 8 combinations, there are 3 in which both persons have the same number of heads (i.e., 0 heads, 1 head, or 3 heads).

In the chi-square goodness-of-fit test, the number of ways in which the expected classes are free to vary is represented by the degrees of freedom (df) of the test.

The degrees of freedom for the chi-square goodness-of-fit test are calculated as df = k - 1, where k is the number of categories or classes being compared.

In this test, we compare the observed frequencies in each category with the expected frequencies, assuming that the null hypothesis is true. The null hypothesis is that there is no significant difference between the observed and expected frequencies, and any deviation between the two is due to chance.

The degrees of freedom are the reflection of the number of independent pieces of information that are available to estimate the expected frequencies.

The more degrees of freedom, the more likely it is that the observed frequencies could be due to chance, and the less significant the test result will be. Conversely, fewer degrees of freedom means that the observed frequencies are more likely to be significantly different from the expected frequencies, and the test result will be more significant.
