The table shown shows the heights of voices.
To get the tallest height you calculate the mean of each voice.
Mean height of soprano;
(60+62+62+64+65+65+66+66+67+68)/10 = 645/10 =64.5
Mean height of alto;
(60+61+62+63+64+65+66+69+70+72)/10 =592/10 =59.2
Mean height of tenor;
(64+66+66+67+68+70+72+73+74+76)/10 = 550/10 =55
mean height of Bass;
(66+68+68+69+70+70+71+72+73+75)/10 = 702/10 =70.2

The two voice parts that have the tallest singers are Soprano and Bass.

These is because the two voices have the highest average height.

Find the slope of the line going through the points (0,6) and (-3,9)

andre [41]

Answer:

The slope of the line is 5.

The point slope form of the line is y=5x+6.

Step-by-step explanation:

We can find the slope using this formula: $\frac{y_{2} }{x_{2} } -\frac{y_{1} }{x_{1} }$

$\frac{6}{0} -\frac{9}{-3} =$

$\frac{6}{0} -(-\frac{9}{3} )=$

$\frac{6}{0} +\frac{9}{3} =$

$\frac{15}{3} =$

The slope of the line is 5.

To find point slope form, we use the equation y=mx+b where m is the slope and b is the y-intercept.

The y-intercept of this slope is 6 and the slope is 5 so we get, y=5x+6

How to reduce into simpler terms.?

Sveta_85 [38]

Answer:

The simplest form of the fraction $\frac{45}{100}$ is $\frac{9}{20}$ .

i.e.

$\frac{45}{100}=\frac{9}{20}$

Step-by-step explanation:

Here are some simple observations regarding how to reduce a fraction into simpler terms:

A fraction is reduced to lowest or simplest terms by finding an equivalent fraction in which the numerator and denominator are as small as possible.

In order to reduce a fraction to lowest or simplest terms, divide the numerator and denominator by their (GCF). Note that (GCF) is also called Greatest Common Factor .

So, lets take a sample fraction and reduce into simpler terms.

Considering the fraction

$\frac{45}{100}$

$\mathrm{Find\:a\:common\:factor\:of\:}45\mathrm{\:and\:}100\mathrm{\:in\:order\:to\:cancel\:it\:out}$
