Answer:

b) 0.1x - 16 is the correct option,

Reason,

-3.4x - 25 + 3x + 0.5x +9 (Perimeter of triangle = Sum of all sides)

=> (-3.4x + 3x + 0.5x) + (9 + (-25))

=> (-3.4x + 3.5x) + (-16)

=> 0.1x - 16

Answer:

1. Circumference= 395.6

2. Circumference= 10.05

3. Circumference= 56.5

4. Diameter= 20

Step-by-step explanation:

We have two right-angled triangles that share a common side, with side lengths 6 and 10. Let's label the sides of the triangles as follows:

Triangle 1:

Side adjacent to the right angle: 6 (let's call it 'a')

Side opposite to the right angle: x (let's call it 'b')

Triangle 2:

Side adjacent to the right angle: x (let's call it 'c')

Side opposite to the right angle: 10 (let's call it 'd')

Using the Pythagorean theorem, we can write the following equations for each triangle:

Triangle 1:\(a^2 + b^2 = 6^2\)

Triangle 2: \(c^2 + d^2 = 10^2\)

Since the triangles share a common side, we know that b = c. Therefore, we can rewrite the equations as:

\(a^2 + b^2 = 6^2\\b^2 + d^2 = 10^2\)

Substituting b = c, we get:

\(a^2 + c^2 = 6^2\\c^2 + d^2 = 10^2\)

Now, let's add these two equations together:

\(a^2 + c^2 + c^2 + d^2 = 6^2 + 10^2\\a^2 + 2c^2 + d^2 = 36 + 100\\a^2 + 2c^2 + d^2 = 136\)

Since a^2 + 2c^2 + d^2 is equal to 136, we can conclude that x (b or c) is between 11 and 12

The parameter is the average number of hours of study time for the entire population of state university students. A parameter is a numerical measurement describing some characteristics of a population.

In this case, the population is the state university students, and the parameter is the average number of hours of study time that they spend each week. When we estimate the average number of hours of study time each week to be 30 ± 2 based on an epsem sample of 300 state university students, we are creating a sample statistic. A sample statistic is a numerical measurement describing some characteristics of a sample. In this case, the sample is the 300 state university students, and the sample statistic is the estimated average number of hours of study time that they spend each week.The sample statistic provides us with information about the population parameter. We can use the sample statistic to make inferences about the population parameter. However, we need to take into account the variability of the sample statistic when making inferences about the population parameter. The sample statistic can be influenced by random sampling variation, which can cause it to be different from the population parameter. Therefore, we need to use inferential statistics to make inferences about the population parameter based on the sample statistic.

In conclusion, the parameter in this example is the average number of hours of study time for the entire population of state university students. The sample statistic is the estimated average number of hours of study time based on the sample of 300 state university students. We can use inferential statistics to make inferences about the population parameter based on the sample statistic.

The two (2) possible locations of point F include the following: F. [7, 9.5].

In this scenario, line ratio would be used to determine the coordinates of the point on the directed line segment that partitions the segment into a ratio of 5 to 3.

Mathematically, line ratio can be used to determine the coordinates of F and this is modeled by this mathematical expression:

F(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

Given the following parameters:

Point (x, y)= (4, 11)

Point (x, y) = (8, 9)

m:n = 3:1

Substituting the given parameters into the line ratio formula, we have;

F(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

F(x, y) = [(3(8) + 1(4))/(3 + 1)],  [(3(9) + 1(11))/(3 + 1)]

F(x, y) = [(24 + 4)/(3 + 1)],  [(27 + 11)/(3 + 1)]

F(x, y) = [(28)/(4)],  [(38)/(4)]

F(x, y) = [7, 9.5]

Various values that are being measured in the sample will increase, which can make the interpretation of the results difficult and potentially confusing.

When a practitioner forgets to ice and ABG sample and leaves it at room temperature for 45 minutes, some of the values that will be increased include the following:1. pH levels:The pH level of the sample is going to rise, leading to an increase in the alkalinity of the blood.2. PaO2:PaO2 (partial pressure of oxygen) is going to decrease since oxygen dissolved in blood will diffuse out into the air.

This will lead to an increase in the level of PaCO2 (partial pressure of carbon dioxide) since the respiratory rate will increase in order to get rid of more CO2.3. PCO2:The partial pressure of carbon dioxide (PCO2) in the sample is going to increase. The increase in PCO2 level in the sample will cause it to become more acidic due to the increase in carbon dioxide.4.

Therefore, under the null hypothesis of no color preference, we would expect each color to be chosen as the first peck by approximately 9 birds.

Under the null hypothesis of no color preference, the expected number of first pecks for each color would be equal.

The null hypothesis assumes that the birds have no preference for any particular color and their choices are purely random. Therefore, we can assume that the probability of choosing each color is the same. Since there are four colors, the expected number of first pecks for each color would be equal to 36 divided by 4, which is 9.

The researcher studying the pecking behavior of 1-day-old bobwhites observed their choices among four pins with different colored heads inserted in an area painted white. The color of the pin chosen on the bird's first peck was noted for 36 bobwhites. To test the hypothesis of whether the birds had a preference for any particular color, we need to calculate the expected number of first pecks for each color under the null hypothesis of no color preference.

Under the null hypothesis, we assume that the birds' choices are purely random and they have no preference for any particular color. Therefore, the probability of choosing each color is the same, which is 1/4. We can use this probability to calculate the expected number of first pecks for each color.

To calculate the expected number of first pecks for each color, we can multiply the total number of birds (36) by the probability of choosing each color (1/4). This gives us the expected number of first pecks for each color as follows:

Expected number of first pecks for each color = Total number of birds x Probability of choosing each color
= 36 x 1/4
= 9

If the observed number of first pecks for any color is significantly different from 9, then we can reject the null hypothesis and conclude that the birds have a preference for that particular color.

The expected value of the game, where a basketball player makes two free throws, is approximately -$15.02. If the player makes both, you receive $1; otherwise, you pay $26.

To find the expected value of the game, we need to calculate the probabilities of the two possible outcomes: the player making the next two free throws and the player missing at least one of the next two free throws.
Probability of making both free throws:
The player has made 229 out of 337 free throws, so the probability of making one free throw is 229/337. Therefore, the probability of making both free throws is (229/337) * (229/337) = 0.4061.
Probability of missing at least one free throw:
The complement of making both free throws is missing at least one free throw. Therefore, the probability of missing at least one free throw is 1 – 0.4061 = 0.5939.
Now, let’s calculate the expected value.
Expected value = (Probability of winning * Amount won) – (Probability of losing * Amount lost)
If you win, you will be paid, so the amount won is positive (+1).
If you lose, you will pay $26, so the amount lost is negative (-26).
Expected value = (0.4061 * 1) – (0.5939 * 26)
Expected value = 0.4061 – 15.424
Expected value ≈ -15.0179
Therefore, the expected value of the game is approximately -15.0179.

Answer:

Step-by-step explanation:

Work Expences

7 pairs of a are sold and 9 pairs of b are sold.

The equation that will be used in solving the equation will be:

a + b = 16 ......... i

45a + 30b = 585 ......... ii

From equation i,

a = 16 - b ...... iii

Put equation iii into ii

45a + 30b = 585.

45(16 - b) + 30b = 585.

720 - 45b + 30b = 585.

Collect like terms

-45b + 30b = 585 - 720

-15b = -135

b = 135/15.

b = 9

Since a + b = 16

a = 16 - b

a = 16 - 9

a = 7

Therefore, 7 pairs of a are sold and 9 pairs of b are sold.
