A historian wants to estimate the average age at which men married in the United States in 1956. He locates marriage records for 1956 in his state's archives and records his findings. What step of the data analysis process is he using?

The value of angle m∠FCG is 27.5.

x = 25

x = 35

We have,

1.

GCH and ECD are alternate angles.

This means,

GCH = 125 = ECD

And,

ECG and DCH are alternate angles.

This means,

ECG = DCH = x

Now,

GCH + ECD + ECG + DCH = 360

125 + 125 + x + x = 360

250 +2x = 360

2x = 360 - 250

2x = 110

x = 55

Now,

ECG = ECF + FCG

55 = ECF + FCG

ECF and FCG are equal.

So,

m∠FCG = 55/2 = 27.5

2.

The straight angles are formed by (5x + 20) and (2x - 5).

So,

5x + 10 + 2x - 5 = 180

7x + 5 = 180

7x = 180 - 5

7x = 175

x = 25

3.

2x + 43 and 2x - 3 are on the same side of the parallel lines.

So,

2x + 43 + 2x - 3 = 180

4x + 40 = 180

4x = 180 - 40

4x = 140

x = 35

Thus,

The value of angle m∠FCG is 27.5.

x = 25

x = 35

The graph and table show the weight of two Chihuahua puppies, A and B, over a 10-week period. We can use the graph to determine the change in weight of Puppy B from week 2 to week 9.

This change in weight can be expressed in various ways, including as the rate at which Puppy B gained weight per week

(B(9) - B(2) divided by 7),

the amount of weight Puppy B gained in ounces during the seven-week interval ending at

t=9 (B(9) - B(2)),

or simply as the difference in height between the two points on the graph representing weeks 2 and 9.

The equation B(t) = A(t) + 3

It represents the relationship between Puppy B's weight and Puppy A's weight at any given time t. Specifically, Puppy B weighs three more ounces than Puppy A at time t.

This equation can be used to calculate Puppy A's weight at any given time if we know Puppy B's weight, or vice versa.

It can also be used to compare the weights of the two puppies at any given time, as the difference between their weights will always be

3 ounces.

Let x be the number of one hour sessions that Mrs. B teaches and let y be the number of half hour sessions that she teaches per week. Then we can write the following system of inequalities to represent her goals:

60x + 40y > 800 (She hopes to make more than $800 tutoring)

x + y <= 12 (She can work a maximum of 12 hours per week)

To determine how many one hour sessions and half hour sessions she can teach, we need to graph these inequalities on a coordinate plane. The graph should show the shaded region that satisfies both inequalities.

To graph the inequality 60x + 40y > 800, we can first rewrite it as:

3x + 2y > 40

Then we can graph the line 3x + 2y = 40 by plotting the points (0,20) and (13.33,0) and drawing a line through them. Since we want to graph the inequality 3x + 2y > 40, we need to shade the region above the line.

To graph the inequality x + y <= 12, we can simply graph the line x + y = 12 by plotting the points (0,12) and (12,0) and drawing a line through them. Since we want to graph the inequality x + y <= 12, we need to shade the region below the line.

The shaded region that satisfies both inequalities is the region that is above the line 3x + 2y = 40 and below the line x + y = 12. This region is a triangle with vertices at (0,12), (8,4), and (13.33,0).

To determine if Mrs. B can teach 5 one hour sessions and 14 half hour sessions, we can plug these values into the inequalities and see if they are satisfied:

60(5) + 40(14) = 860 > 800 (This inequality is satisfied)

5 + 14 = 19 <= 12 (This inequality is not satisfied)

Since the second inequality is not satisfied, it is not possible for Mrs. B to teach 5 one hour sessions and 14 half hour sessions.

Answer: The formula for simple interest is:

I = Prt

Where:

I is the interest earned

P is the principal (the initial amount deposited)

r is the interest rate (as a decimal)

t is the time period in years

Using this formula, we can calculate the interest earned by Patricio after 4 years:

I = Prt

I = 800 * 0.025 * 4

I = 80

So, after 4 years, Patricio will have earned $80 in interest. Adding this to the initial deposit of $800, the total amount of money he will have in the account is:

Total = P + I

Total = 800 + 80

Total = $880

Therefore, Patricio will have $880 in the savings account after 4 years.

Some alkenes have geometric cis-trans isomers because of the presence of a double bond between two carbon atoms. In a carbon-carbon double bond, the carbon atoms are connected to two different groups of atoms, which can be oriented differently in space. In the cis configuration, the two substituent groups on each carbon atom are on the same side of the double bond, while in the trans configuration, the two substituent groups on each carbon atom are on opposite sides of the double bond.

The cis-trans isomerism arises due to the restricted rotation around the carbon-carbon double bond. In the case of cis isomers, the substituent groups are too bulky to rotate around the double bond, and they remain on the same side of the double bond. In contrast, in the trans isomers, the substituent groups are oriented on opposite sides of the double bond, which allows them to rotate freely around the bond.

The presence of cis-trans isomers has important consequences for the physical and chemical properties of alkenes, including their reactivity, solubility, and melting points. The two isomers can have different properties and can exhibit different biological activities, making them important targets for drug design and synthesis.

A ratio is a comparison of two or more quantities expressed as a fraction. For example, if we say that the ratio of apples to oranges is 2:3, it means that for every two apples, there are three oranges. Ade received an amount of 1500 from the total sum of 4000 .

In order to find out the amount Ade received, we need to first understand the concept of ratio. A ratio is a comparison of two or more quantities expressed as a fraction. For example, if we say that the ratio of apples to oranges is 2:3, it means that for every two apples, there are three oranges.

In this problem, we are given that Ade and Ola share a sum of 4000 in the ratio of 3:5. This means that the total ratio is 3+5 = 8.

To find out the amount Ade received, we need to first find the fraction of the total sum that belongs to Ade. We can do this by dividing Ade's ratio by the total ratio.

Ade's ratio is 3, so the fraction of the total sum that belongs to Ade is 3/8.

Now, we can find the amount Ade received by multiplying this fraction by the total sum:

Amount Ade received = (3/8) x 4000 = 1500.

1.Add the ratio parts: 3 (Ade's part) + 5 (Ola's part) = 8 total parts.

2. Divide the total sum (4000) by the total parts (8): 4000 ÷ 8 = 500. This gives us the value of one part.

3. Multiply Ade's ratio part (3) by the value of one part (500): 3 × 500 = 1500.

So, Ade received an amount of 1500 from the total sum of 4000.

Answer:

x = 9

Step-by-step explanation:

30 = 2(x +6)

30 = 2x +12

Subtract 12 from both sides.

18 = 2x

divide both sides by 2.

9 = x

First, we can simplify the equation by dividing both sides by 2:

30/2 = x + 6

This gives us:

15 = x + 6

Now we can solve for x by subtracting 6 from both sides:

15 - 6 = x

Therefore, the solution is:

x = 9.
