If the data is symmetrical, then the mean is the best measure of central tendency to use, and the standard deviation is the best spread to use.

If the data is asymmetrical, the median is the best measure of central tendency to use, and the inter-quarterly range is the best spread to use.

<h3>What are symmetrical and asymmetrical data?</h3>

A histogram for symmetrical data will give a symmetrical shape, and the mean, median and mode will all be the same value. Therefore, the best measure of the central tendency to use is the mean. The standard deviation shows how far away the values in a given data set are from the mean, and since the mean is used as the measure of central tendency in this case, the standard deviation should be used as the spread.

A histogram for a an asymmetric data set will give an asymmetric shape, and the mean is not always equal to the median. Therefore, the best measure of central tendency to use is the median. The inter-quarterly range shows the range of the middle 50% of a certain data, which is considered from the median value. Since the median is used as the measure of central tendency in this case, it is wise to use the inter-quarterly range as the measure of spread.

Work out the size of the angle marked t
tiny-mole [99]

Answer:

<h2>35°</h2>

Step-by-step explanation:

This is an isoceles triangle

And as we all know an isoceles triangle has two equal base angles.

And we also know that the sum of all interior angles of the triangle is 180°

So based on this we can form an algebraic equation of solve for angke t (Let's do it :))

110 + 2t = 180 \\ 2t = 180 - 110 \\ 2t = 70 \\ t  =  \frac{70}{2}  \\ t = 35

So the base angle is 35°

5x=4y+8 3y=3x-3 using elimination
suter [353]
Let's rewrite the equation with x and y on the left side of the equal sign.  
5x-4y=8 --------(1) 
3x-3y=3---------(2)  
Divide equation (2) by 3, 
x - y= 1 
now we have, 
5x-4y = 8 --------(1) 
x - y = 1 ---------(2)  
To eliminate x, multiply equation (2) by 5. This makes both the coefficients of x to be 5. Subtract the second equation from the first equation.  
5x - 4y = 8 
(2) * 5 5x - 5y = 5 
(-) (+) (-) 
---------------- 
 0x +y =3
 Therefore, y=3 
 Substitute the value of y, in any one of the two equations. Let's substitute y in the second equation.
 x-3=1
 x=4 
 x=4 and y=3
