Foresters want to estimate the average age of trees in a stand. Determining age is cumbersome, because one needs to count the tree rings on a core taken from the tree. In general, though, the older the tree, the larger the diameter, and diameter is easy to measure. The foresters measure the diameter of all 1132 trees and find that the population mean equals 10.3. They then randomly select 20 trees for age measurement

Answer:

Triangle 2: 7, 24 and 25.

Step-by-step explanation:

To find the triangle with its dimensions being that of a right angle triangle;

We would have to apply Pythagorean' theorem.

Let the length of sides of the triangle be;

Opposite side = a

Adjacent side = b

Hypotenuse side = c

From Pythagorean theorem;

c² = a² + b²

When a = 7, b = 24 and c = 25

25² = 7² + 24²

625 = 49 + 576

625 = 625

This ultimately implies that, the square of the hypotenuse of a right angle triangle is equal to the sum of the square of its opposite and adjacent sides according to Pythagorean' theorem.

The solution is Option B.

The value of the equation is x = 2

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

x + 5 = 7   be equation (1)

On simplifying the equation , we get

Subtracting 5 on both sides of the equation , we get

x = 7 - 5

x = 2

Therefore , the value of x is 2

Hence , the equation is x = 2

2.       46

3.      0

Step-by-step explanation:

math

Answer:

1. x = 42

2. y = 46

3. z = 0

Step-by-step explanation:

1. 45 + x = 87

         subtract 45 from both sides

  x = 42

2. y - 31 = 15

         add 31 to both sides

  y = 46

3. 5z = 0

         divide 5 from both sides

  z = 0/5

         since any fraction with a numerator of 0 is equal to 0, we get

  z = 0

Step-by-step explanation:

North

The northern soil and climate favored smaller farmsteads rather than large plantations. Industry flourished, fueled by more abundant natural resources than in the South, and many large cities were established (New York was the largest city with more than 800,000 inhabitants). By 1860, one quarter of all Northerners lived in urban areas. Between 1800 and 1860, the percentage of laborers working in agricultural pursuits dropped drastically from 70% to only 40%. Slavery had died out, replaced in the cities and factories by immigrant labor from Europe. In fact an overwhelming majority of immigrants, seven out of every eight, settled in the North rather than the South. Transportation was easier in the North, which boasted more than two-thirds of the railroad tracks in the country and the economy was on an upswing.

Far more Northerners than Southerners belonged to the Whig/Republican political party and they were far more likely to have careers in business, medicine, or education. In fact, an engineer was six times as likely to be from the North as from the South. Northern children were slightly more prone to attend school than Southern children.

South

The fertile soil and warm climate of the South made it ideal for large-scale farms and crops like tobacco and cotton. Because agriculture was so profitable few Southerners saw a need for industrial development. Eighty percent of the labor force worked on the farm. Although two-thirds of Southerners owned no slaves at all, by 1860 the South's "peculiar institution" was inextricably tied to the region's economy and culture. In fact, there were almost as many blacks - but slaves and free - in the South as there were whites (4 million blacks and 5.5 million whites). There were no large cities aside from New Orleans, and most of the ones that did exist were located on rivers and coasts as shipping ports to send agricultural produce to European or Northern destinations.

Only one-tenth of Southerners lived in urban areas and transportation between cities was difficult, except by water.  Only 35% of the nation's train tracks were located in the South. Also, in 1860, the South's agricultural economy was beginning to stall while the Northern manufacturers were experiencing a boom.

A slightly smaller percentage of white Southerners were literate than their Northern counterparts, and Southern children tended to spend less time in school. As adults, Southern men tended to belong to the Democratic political party and gravitated toward military careers as well as agriculture.

Answer:

X=2,3

Step-by-step explanation:

Answer:

A) I consumed 69 calories.

B)  There are 21 cashews in one serving.

Step-by-step explanation:

Given that the nutrition facts label on a container of dry roasted cashews indicates there are 161 calories in 28 grams, and I eat 9 cashews totaling 12 grams, to determine how many calories do I consume and how many cashews are in one serving should be performed the following calculations:

A)

28 = 161

12 = X

12 x 161/28 = X

1932/28 = X

69 = X

So, I consumed 69 calories.

B)

12 = 9

28 = X

28 x 9/12 = X

252/12 = X

21 = X

Therefore, there are 21 cashews in one serving.

Step-by-step explanation:

Hi! So there is no equation, image, or otherwise added here which would make it difficult to answer your question. X is always changing based on the situation. But if you have an equation you should be able to simplify the equation and then take the quadratic formula to get the value of x. If you have  a graph you can find the rise/run.

The central angle of the shaded region is 40 degrees so we have to multiply [tex]3^2\pi[/tex] by [tex]\frac{40}{360}[/tex] or [tex]\frac{1}{9}[/tex]. 3 squared is 9 so 9[tex]\pi[/tex] times [tex]\frac{1}{9}[/tex] is just equal to [tex]\pi[/tex].
