Wewaii [24]

Answer:

d = √34

Step-by-step explanation:

(-2, -1) & (3, 2)

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

denis-greek [22]

Answer:

The surface area is 116 square inches

Step-by-step explanation:

Given

L = 7 -- Length

W = 4 -- Width

H = 4 -- Height

Required

Determine the surface area of the box [Missing from the question]

Since the box has no lid, the surface area is:

Area = 1\ bottom + 2\ fronts + 2\ sides

Area = 7 * 4 + 2 * 7 * 4 + 2 * 4 * 4

Area = 116

<em>Hence, the surface area is 116 square inches</em>

the equation y=5,280x gives the number of feet,y,in x miles.what does the number 5,280 represent in this relation ship
siniylev [52]

The term 5280 represents the number of feet in a mile in this relationship y=5,280x.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The linear equation is:

y=5,280x

The number 5,280 here represents the number of feet in a mile in this connection.

The equation is calculated:

Since Y=5,280x, the equation

It gives the quantity, y, of feet in x miles.

We may conclude that 5,280 represents the number of feet in a mile in this relationship.

Thus, the term 5280 represents the number of feet in a mile in this relationship y=5,280x.

rjkz [21]

The test statistic and p-value of the given data are 6.274 and 0.0001 respectively.

<h3>Test Statistic</h3>

The test statistic can be calculated using the formula below

t = \frac{x-\mu}{\sigma / \sqrt{n} }

Solving for the mean and standard deviation, we can substitute the values into the above equation which will be

t = \frac{x-\mu}{\sigma / \sqrt{n} } = 6.274

<h3>P-Value</h3>

Using the data from the test statistic, we can calculate the p-value of the data

p-value = p(z < 6.274)= 0.0001 = 0.00

From the calculation above, the test statistic and p-value of the given data are

  • 6.274
  • 0.0001
