In a recent year, there were 15,900,000 high school
students in the United States. Suppose 250,000 of a
random sample of 500,000 high school students
during that year played on a sports team. Estimate
the total number of U.S. High school students that
played on a sports team that year.

Answers

Answer 1

Answer:

The total number of U.S. high school students that played on a sports team that year can be estimated to be 7,950,000.

Step-by-step explanation:

From the random sample, we can expect that [tex]\frac{250000}{500000}=\frac{1}{2}[/tex] of all students played on a sports team that year. So in the bigger sample of 15900000 high school students, we can expect [tex]15900000 \cdot \frac{1}{2} = 7950000[/tex] students to have played on a sports team that year.

Solve the system by substitution.
y = 5x
y = 9x + 4

Answers

Answer:

(-1, -5)

Step-by-step explanation:

[tex]\left \{ {{y=5x} \atop {y=9x+4}} \right.[/tex]

1. We must calculate x, for that we must substitute y, so we have:

5x=9x+4

2. Now we solve the equation.

5x-9x=4

-4x=4

x=-1

3. Now we must calculate y

y=5x

y=5(-1)

y=-5

And the answer is (-1, -5)

Identify whether the expressions are equivalent or not equivalent: 7y – 15 + 2y and 9y - 15

Answers

Answer:

Yes, the two expressions are equivalent

The given expression 7y - 15 + 2y and   9y - 15 are equivalent.  

What is equivalent expression?

Two algebraic expressions are said to be equivalent if their values obtained by substituting the values of the variables are same, even they look different.

According to the given question.

We have two expressions

[tex]7y - 15 + 2y ...(i)[/tex]

And, [tex]9y - 15 ...(ii)[/tex]

The expression (i) can be written as

[tex]7y - 15 + 2y[/tex]

[tex]=(7y + 2y)-15[/tex]            (adding the like terms)

[tex]= 9y -15[/tex]    

Hence, the given expression 7y - 15 + 2y and   9y - 15 are equivalent.

Answer:

p=-2

Step-by-step explanation:

Move the -3 to the other side by adding 3 on both sides:

-6p-3+3=9+3

The equation now looks like this:

-6p=12

Divide -6 on both sides:

-6p/-6=12/-6

The equation now looks like this:

p=-2 which is the answer

What is 9/2 × 20/3 × 9/4?

Answers

Answer:

67.5

Step-by-step explanation:

4.5 times 6.66 times 2.25 will be 67.5

Well, when multiplying fractions together, you don’t really have any problem of converting fractions for common denominators or any of that stuff and instead it’s actually quite simple because you just have to straight multiply the numerators and the denominators

9/2 * 20/3 * 9/4
= (9 * 20 * 9)/(2 * 3 * 4)
= (1620)/(24)
= 1620/24
= 67.5

So, in conclusion, 9/2 * 20/3 * 9/4 is equal to 67.50 or 1620/24.

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).

Given:

The Burj Khalifa, a building in Dubai,

United Arab Emirates, is about 828 meters tall.

Brody is making a scale model of this building,

using the scale factor 1:500.

The height of the model = 828 / 500 = 1.656

= 1.7 to the nearest tenth.

Therefore, the model is 1.7 meters tall to the nearest tenth.

Graph the line with a slope of 2/3 that contains the point (−3,−5)

Answers

Answer:

Step-by-step explanation:

So for the given information, it would be easiest to use slope-intercept form, which is y=mx + b, where m is the slope and b is the y-intercept.

We can plug in 2/3 for the slope, because we are given that.

y=2/3x + b.

To find the y-intercept, plug in the given point for x and y and solve for b.

-5 = 2/3 · (-3) + b

-5 = -2 + b

b = -3

So now we have the complete equation of the line.

y = 2/3x -3

Now to graphing.

We can put the y-intercept, (0, -3), and the given point, (-3, -5) on a graph.

Anyone who has ever tried to make anything with these kinds of tools knows how limiting they are: if you hit a piece of wood it either splinters, cracks, or snaps. The same is true of rock or bone. Metals are fundamentally different from these other materials because they can be hammered into shape: they flow, they are malleable. Not only that, they get stronger when you hit them; you can harden a blade just by hammering it. And you can reverse the process simply by putting metal in a fire and heating it up, which will cause it to get softer. The first people to discover these properties ten thousand years ago had found a material that was almost as hard as a rock but behaved like a plastic and was almost infinitely reusable. In other words, they had discovered the perfect material for tools, and in particular cutting tools like axes, chisels, and razors. This ability of metals to transform from a soft to a hard material must have seemed like magic to our ancient ancestors. *** In 1961 Professor Richmond from Oxford University discovered a pit that had been dug by the Romans in AD 89. It contained 763,840 small two-inch nails, 85,128 medium nails, 25,088 large nails, and 1,344 extra-large sixteen-inch nails. The hoard was of iron and steel and not gold, which most people would have found bitterly disappointing. But not Professor Richmond. Why, he asked himself, would a Roman legion bury seven tons of iron and steel? The legion had been occupying the advance headquarters of Agricola in a place called Inchtuthil in Scotland. This was at the outer reaches of the Roman Empire, and their mission was to protect its border from what they saw as the savage tribes who threatened it: the Celts. The legion of five thousand men occupied the region for six years before retreating and, in the process, abandoning their fort. They made great efforts to leave behind nothing that could help their enemies. They smashed all food and drink containers and burned the fort to the ground. But they werent satisfied with this. In the ashes were the steel nails that had held the fort together, and they were far too valuable to be left to the tribes that had driven them out. Iron and steel were the materials that enabled the Romans to build aqueducts, ships, and swords; they allowed them to engineer an empire. Leaving the nails to their enemies would have been as useful as leaving a cache of weapons, so they buried them in a pit before marching south. Which line from the excerpt provides context that supports the meaning of the word malleable? a) metals are fundamentally different b) hammered into shape c) they flow d ) stronger when you hit them what was the first plan of goverment in north america.what this plan do HELP I NEED HELP ASAP During elections in a democracy, it is important that all citizens exercise their right todetermine their future by voting.The suffix -cracy means "form of government."
