Answer:The greatest possible error of a measurement is considered to be one-half of the measuring unit. If you measure a length to be 4.3 cm. (measuring to the nearest tenth), the greatest possible error is one-half of one tenth, or 0.05. This means that any measurements in the range from 4.25 cm. to 4.35 cm. are perceived as correct.

Step-by-step explanation:

Answer:

The greatest possible error for a measurement of 0.05 metric tons would depend on the accuracy of the measurement device or technique being used. Without more information about the specific measurement method, it is impossible to determine the greatest possible error.

Answer: A. A number is an integer

Step-by-step explanation:

When we write a statement such as “If P then Q” we should note that the statement means that anytime P is true, it also means that Q must also be true.

The statement P is what we refer to as a hypothesis of the conditional statement, while we refer to the statement Q as conclusion of a conditional statement.

In the above example, the hypothesis if the conditional will be "a number is an integer" while the conclusion will be "it is either positive or negative".

By applying velocity concept, it can be concluded that the height of the object is 48 feet at 1 second and 3 seconds.

Velocity is the distance traveled, and the direction in which the distance is changing. It can also be described as the instantaneous rate of change of a moving object.

velocity = Δs / Δt  , where:

Δs = distance change

Δt  = time change

The height of the object is given by the equation h = -16t² + 64t.

We need to find the time t when the height is 48 feet.

To do this, we can plug in the value of h and solve for t:

 h = -16t² + 64t

48 = -16t² + 64t

 0 = -16t² + 64t - 48

Dividing by -16 gives us:

0 = t² - 4t + 3

  = (t - 3)(t - 1)

Therefore, the possible values of t are 1 and 3 seconds.

So, the height of the object is 48 feet at 1 second and 3 seconds.

It will take 5.00 seconds for the object to reach a height of 48 feet.

To answer this question, we need to use the equation given: h = -16t2 + 64t. We know that the height is 48 feet and need to calculate the number of seconds it will take to reach this height.

We can rearrange the equation to solve for t, which will give us the number of seconds it takes to reach 48 feet:

48 = -16t2 + 64t

To solve for t, we can use the quadratic formula:

t = (-64 ± √(642 - 4(-16)(48))) / (2(-16))

After simplifying, we get:

t = (8 ± √384) / -32

Therefore, the two solutions are t = 5.00 seconds and t = -6.25 seconds.

Since the object is being propelled upwards, the only solution that makes sense is t = 5.00 seconds.

Therefore, it will take 5.00 seconds for the object to reach a height of 48 feet.

This statement best illustrates money used as a medium of exchange. In this scenario, the individual goes to the store and exchanges $68 for a pair of jeans. Money serves as a medium of exchange when it is used to facilitate transactions between buyers and sellers. In this case, the buyer wants a pair of jeans, and the seller wants to sell them for $68. Without money, they would have to engage in bartering, which can be cumbersome and inefficient. Money makes the transaction smoother and allows both parties to get what they want. Overall, this example demonstrates how money is an essential tool for facilitating transactions in our modern economy.
Hi! Your question is about the function of money as illustrated by the example of paying $68 for a pair of jeans. This statement best illustrates money used as a medium of exchange.

In this scenario, money is being used as a medium of exchange because it is facilitating the transaction between you and the store. Instead of using barter or trading goods and services directly, you use money to acquire the pair of jeans. This makes transactions more efficient and convenient since it eliminates the need for a double coincidence of wants, which is when two parties each have something the other wants. As a medium of exchange, money serves as a universally accepted means to buy and sell goods and services, like your jeans purchase at the store.

In 1960, the percentage of black students attending integrated schools in the South was approximately 2%.

Brown v Board of Education was a landmark decision in 1954 that declared segregation in public schools unconstitutional. However, it took several years for this decision to be implemented in Southern states, and in 1960, only 2% of black students in the South attended integrated schools. This highlights the resistance to desegregation in Southern states and the slow pace of change. It also underscores the ongoing struggles for civil rights and the continued efforts to address systemic racism in education and other aspects of American society.

1. 48,000 oz = 1.5 ton, 2. 4 and 1/5 T = 8,400 lb, 3. 7 gal = 56 pt, 4. 125 fl oz = 3.90625 qt 5.  the perimeter of the rectangle is 132.8 m.

Measurement units are standard quantities used to express physical quantities, such as length, mass, time, volume, and temperature. They provide a standard framework for expressing and comparing quantities, allowing for precise and accurate communication and measurement.

There are two types of measurement units: fundamental units and derived units. Fundamental units are the basic units used to express physical quantities, such as meter (for length), kilogram (for mass), and second (for time). Derived units are combinations of fundamental units used to express other physical quantities, such as square meters (for area) or meters per second (for speed).

1. To convert 48,000 oz to T (tons):

1 ton = 32,000 oz (since there are 2,000 pounds in a ton, and 1 pound = 16 ounces)

48,000 oz ÷ 32,000 oz/ton = 1.5 T

Therefore, 48,000 oz = 1.5 T

2. To convert 4 and 1/5 T to lb (pounds):

1 ton = 2,000 lb

4 T = 8,000 lb

1/5 T = 1/5 x 2,000 lb = 400 lb

4 and 1/5 T = 8,000 lb + 400 lb = 8,400 lb

Therefore, 4 and 1/5 T = 8,400 lb

3. To convert 7 gal to pt (pints):

1 gal = 8 pt

7 gal x 8 pt/gal = 56 pt

Therefore, 7 gal = 56 pt

4. To convert 125 fl oz to qt (quarts):

1 qt = 32 fl oz

125 fl oz ÷ 32 fl oz/qt = 3.90625 qt

Therefore, 125 fl oz = 3.90625 qt

5. The perimeter of a rectangle with sides of 17.1 m and 49.3 m can be found by adding up all four sides:

Perimeter = 2(17.1 m) + 2(49.3 m) = 34.2 m + 98.6 m = 132.8 m

Therefore, the perimeter of the rectangle is 132.8 m.

Answer:

Step-by-step explanation:

The function that has a range of {y | y > -10} is any linear function with a positive slope and a y-intercept greater than -10.

In mathematical terms, we can represent this function as y = mx + b, where m is the slope and b is the y-intercept.

For the range to be {y | y > -10}, the function's y-values must be greater than -10.

This means that the line must be above the horizontal line y = -10.

A linear function with a positive slope will always have a range that extends to positive infinity, as the y-values increase indefinitely as x increases.

However, to satisfy the condition that y > -10, the y-intercept must also be greater than -10.

The y-intercept represents the value of y when x is equal to 0. So, the function must have a y-intercept greater than -10 to ensure that all y-values are greater than -10.

Overall, any linear function with a positive slope and a y-intercept greater than -10 will have a range of {y | y > -10}.

A higher slope indicates a stronger relationship between the variables, and the sign (positive or negative) indicates the direction of the relationship (positive: both variables increase together, negative: one variable increases while the other decreases).

When comparing the slopes of the regression lines for two models, you're essentially looking at the differences in their unstandardized coefficients. These coefficients represent the change in the dependent variable for each unit change in the independent variable, keeping all other variables constant.

In the unstandardized model you mentioned, the slope of 0.96 means that for every one-unit increase in the independent variable, the dependent variable is expected to increase by 0.96 units, on average. This helps us understand the strength and direction of the relationship between the two variables in the model.

To compare the slopes between two models, simply examine their unstandardized coefficients.

Yes you are correct. The diagonals of any kite are perpendicular.

This can be proven by showing that triangle KGH is congruent to triangle KJH through the SSS congruence theorem. From there you break up the triangles focusing on triangle JRK and triangle GRK, now using the SAS rule to conclude that angle JRK = angle GRK. Since those are a linear pair, those angles must be right angles.

Side note: A kite is defined to be any quadrilateral in which it has two pairs of adjacent congruent sides. Not all four sides are the same length though (otherwise we would have a rhombus).

The number of pies that Red Riding Hood takes to her grandmother: 1/2(x - 1)

0.5(x - 1)

0.5x - 0.5

Pies left after Red Riding Hood ate 2: [(0.5x - 0.5) - 2]

Pie after she gave the wolf 1/3 ; (1 - 1/3) × [(0.5x - 0.5) - 2]

2/3 × [(0.5x - 0.5) - 2]  = 8

In order to determine the value of x, take the following steps:

Multiply both sides of the equation by 3/2.

[(0.5x - 0.5) - 2] = 12

Add 2 to both sides of the equation: 0.5x - 0.5 = 12 + 2

0.5x - 0.5 = 12

Step-by-step explanation:

Find the vertex

¼(x-5) = (y-2)²

x-5 = 4(y-2)²

x = 4(y-2)² + 5

This is a right-opening parabola with vertex (5,2).

focal length p = 1/(4·coefficient of y²) = 0.0625

directrix: x = 5-p = 4.9375

D

The equation of directrix of the parabola will be x = 4, i.e. Option A.

Directrix is a straight line distance to which from any point of a conic section is in fixed ratio to the distance from the same point to a focus. The directrix is perpendicular to the axis of symmetry and does not touch the parabola.

We have,

\(\frac{1}{4} (x - 5) = (y - 2)^2\)

Now,

Rewrite as,

\((x - 5) = 4(y - 2)^2\)

Now,

\(x= 4(y - 2)^2+5\)

Now,

Comparing it with the vertex form,

i.e.

\(x = a ( y - h )^ 2 + k\)

Vertex of parabola = (2, 5),

So,

Focus at (a, 0),

So,

Focus of the parabola = (4, 0),

i.e., a = 4

Now,

The Equation of directrix is given by x = a

So,

The equation of the directrix of this parabola,

x - a = 0,

i.e.

x - 4 = 0

⇒

x = 4

Hence, we can say that the equation of directrix of the parabola will be x = 4, i.e. Option A.
