what is the equation in slope intercept form for the line that passes through the points (-2,-1) and (1,5)

The cost of a council tax bill increased by 5%.

andreyandreev [35.5K]

The council tax bill before the increase is £1240

The equation that represents the percentage increase in council tax bill is :

percentage increase x t = £62

Where t represents the initial council tax bill - council tax bill before the 5% increase

5% x t = £62

0.05 x t = £62

Divide both sides of the equation by 0.05

t = £62 / 0.05 = £1240

To check if the answer derived is correct : 5% x 1240 = 62.

HELP!!!!!!!!!!!!!!!!!!!!!!!!!! Can U Answer All These.

mash [69]

QUESTION 1

In figure A, the area of the bigger square is $625\:units^2$ . This means that the length of this square is the hypotenuse of the right angle triangle formed, which is $25\:units$ .

The area of the two smaller squares are $576\:units^2$ and $49\:units^2$ .

The length of these two squares form the two shorter legs of the right angle triangle, which are $24$ and $7$ units respectively.

Therefore we can write the equation, $576+49=625$ .

This implies that, $24^2+7^2=25^2$

We can see that the sum of the squares of the two shorter legs equals the square of the longer side which is the hypotenuse and this what the Pythagoras theorem says.

But in fig. B,

$5^2+4^2\ne 6^2$

Therefore the correct answer is Fig A.

QUESTION 2

See diagram.

We introduce the two lines as shown in the diagram.

From Pythagoras' Theorem,

$|AB|^2=|AC|^2+|BC|^2$

But $|AC|=|7-3|=4$ units.

and

$|BC|=|8-2|=6$ units.

This implies that,

$|AB|^2=4^2+6^2$

$|AB|^2=16+36$

$|AB|^2=52$

$|AB|=\sqrt{52}$

$|AB|=2\sqrt{13}$

$|AB|=7.2$ to the nearest tenth.

QUESTION 3

The numbers $3,4$ and $5$ form a Pythagorean triplet because $3^2+4^2=5^2$ .

If these numbers represent the side lengths of a triangular fence, then the triangular fence must be a right angle triangle.

The correct answer is B

Yes,because $3^2+4^2=5^2$ .

QUESTION 4

See graph.

We want to find the image of the triangle with vertices A(-5,-4), B(-2,-4), and C(-5,-1) after a reflection in the x-axis.

The mapping for this transformation is

$P(x,y)\rightarrow P'(x,-y)$ .

We just have to negate the y-coordinates.

$A(-4,-5)\rightarrow A'(-4,5)$ .

$B(-4,-1)\rightarrow B'(-4,1)$ .

$C(-5,-1)\rightarrow C'(-5,1)$ .

A statistic is said to be unbiased if

xxMikexx [17]

Answer:

A statistic is said to be unbiased if the mean of its sampling distribution is equal to the true value of the parameter being estimated.

Step-by-step explanation:

A parameter is a number that describes the population.

A statistic is a number that describes a sample.

A statistic used to estimate a parameter is unbiased if the mean of its sampling distribution is exactly equal to the true value of the parameter being estimated. For example, the mean of a sample is an unbiased estimate of the mean of the population from which the sample was drawn.

A statistic is biased if its expected value is not equal to the parameter.
