PLEASE HELP ME WITH THIS STATISTICS WORK SAMPLE (will give brainliest)

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.

Rewind the "mind movie" of what happened. She added $74 to her account and then had $192. Back it up by subtracting the $74 from $192.

192 - 74 = 118

Answer:

a) = 14, because we solve the absolute value first, making it 9 + 5.

b) = 4, because we solve -9 + 5 first, which equals -4, then we solve the absolute value which is 4.

X-2y=1;3x-6y=3 substitution

emmainna [20.7K]

Answer:

All solutions

Step-by-step explanation:

When solving by substitution, we will first set one equation equal to a variable, and then plug that value into the second equation as the variable. Here is what I mean;

x - 2y = 1

3x - 6y = 3

x = 1 + 2y

3x - 6y = 3

3(1 + 2y) - 6y = 3

3 + 6y - 6y = 3

3 = 3

[] Oh no! This doesn't work well. Let's graph it and see what is happening;

-> See attached

-> I have made the lines very thick so you can see the overlap, they are the same size in reality

The answer is all solutions because the graphs are exactly the same.

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.
