Answer:
-62
Step-by-step explanation:
Answer:
y = -4/5 x - 6
Step-by-step explanation:
First turn both standard form equations to slope-intercept form.
4x + 5y = 10 -3x - 4y = 24
-4x -4x +3x +3x
<u>5y</u> = <u>-4x + </u><u>10</u> <u>-4y</u> = <u>3x + 24</u>
5 5 -4 -4
y = -4/5 x + 2. y = -3/4 x - 6
Now that you have each in slope-intercept form, we can begin the magic.
So we know that this line's y-intercept will be -6.
Not to mention since it's parallel, that means it will share the same slope as y = -4/5 x + 2, which the slope is -4/5. All together it will be
y = -4/5 x - 6. Now we can graph the line's to see if we we're right. (Look at graphs, attached above⤴⤴⤴) As you can see they are parallel.
Hope this helped :)
We are given the data 4 8 5 12 3 9 5 2 and is asked for the mean and standard deviation of the numbers or data set. The mean is the average equal to 6. The standard deviation reveals the spread of the data. In this case, the standard deviation is equal to 3.16
Answer: 1%
Explanation:
Add up the frequencies in the bottom row: 350+200+245+125+66+10+4 = 1000
There are 1000 families total. Of this total, 10+4 = 14 families have more than six people. I added up the frequency counts for "7 people" and "8 people" to get 14.
Divide 14 over 1000 and we get 14/1000 = 0.014 = 1.4% which rounds to 1%
