Which game isn’t fair for two players to play?

The sides of a triangle are in the ratio 1 : 2 : 4. The difference between the longest side and the shortest side is 84 cm. What is the perimeter of the triangle ?

The sides of a triangle are in the ratio 1: 2: 4. (Given)

Let the three sides of a triangle be x, 2x and 4x respectively.

So,

ATQ ,

4x - x = 84

3x = 84

x = \( \bf \frac{84}{3} \)

\( \therefore \) Longest side = 4x = 4 × 28 = 112 cm.

Shortest side = x = 28 cm.

And, the other side = 2x = 2 × 28 = 56 cm

Now, we have to find the perimeter of the triangle.

Hence, Perimeter of the triangle = (112 + 56 + 28) cm = 196 cm.

Step-by-step explanation:

The equation y=x^2+7x-15 is a quadratic equation. It might be the result of a quadratic regression.

_____

The descriptors "linear," "quadratic," "exponential," and "power" describe the sort of equation that is used to try to match the data. Quadratic regression returns a quadratic equation.

The graph of the linear function 4x + 6y = -12 is given by the image presented at the end of the answer.

The slope-intercept representation of a linear function is given by the equation presented as follows:

According to the Angle Addition Postulate, the measure of m∠ABD = 202°.

According to the Angle Addition Postulate, an angle's measure is equal to the sum of the measures of any two adjacent angles. The Angle Addition Postulate can be used to determine the measurement of a missing angle or to determine the angle produced by two or more other angles.

Given:

The angle measures:

m∠ABC=37°,

and m∠⁡C⁣B⁣D= 165⁢°.

So, according to the angle addition postulate;

m∠ABD = m∠ABC + m∠CBD

Substituting the values,

m∠ABD = 37° + 165⁢°

m∠ABD = 202°

Therefore, the angle measure of m∠ABD = 202°.

YES, Standardized score necessarily a z-score.

Z-scores, usually referred to as standardized scores, are data values or scores that have been assigned a common standard. This benchmark has a zero mean and a one standard deviation. Contrary to popular belief, z-scores are not always evenly distributed.

By reducing a score's variance by the standard deviation in a data set, the z-score, also known as the standard score, may be used to standardize scores on the same scale. A standard score is the end outcome. It counts how many standard deviations a particular data point deviates from the mean. Z-scores can be either positive or negative.

Answer:

The region where the inequality is valid is (x>-5) and (x<-9).

The graph is attached.

Step-by-step explanation:

We have a inequality and we have to determine the region in the xy-plane that inequality.

\(|x+7|-2>0\\\\|x+7|-2+2>0+2\\\\|x+7|>2\)

We divide the inequality in two regions:

1) When (x+7)>0, we have:

\(x+7>2\\\\x+7-7>2-7\\\\x>-5\)

2) When (x+7)<0, we have:

\(-(x+7)>2\\\\-x-7+7>2+7\\\\-x>9\\\\(-x)(-1)<9(-1)\\\\x<-9\)

Then, the region where the inequality is valid is (x>-5) and (x<-9).

\( = \frac{2 \sqrt{2} - \sqrt{3} }{ \sqrt{2} + \sqrt{3} } \times \frac{ \sqrt{2} - \sqrt{3} }{ \sqrt{2} - \sqrt{3} } \)

\( = \frac{ 2( \sqrt{2} - \sqrt{3} )( \sqrt{2} - \sqrt{3} )}{ { \sqrt{2} }^{2} - { \sqrt{3} }^{2} }\)

\( = \frac{2(2 - \sqrt{6} - \sqrt{6} - 3) }{2 - 3} \)

\( = \frac{2( - 1 - 2 \sqrt{6} )}{ - 1} \)

\( = \frac{ - 2(1 + 2 \sqrt{6} )}{ - 1} \)

\( = 2(1 + 2 \sqrt{6} )\)
