Normally, one would have a certain pattern and they would make an equation to make the prediction for what values would come next in a sequence ( or at some x value ), but if one had an equation such as y=3x+4 ( I am using examples because this was a very general question ) they could see that when x is 0 y=4 and that the y value increases three units for every change in x value. since y=4 when x=0, 4 may be called the initial value as well as the y-intercept ( in fact this is generally true for all mathematical models ). This is where the pattern starts.
They make 18 chicken burritos because when you do 24 beef burritos total divided by 4 beef burritos you get 6 beef then you muliply 6 by the number of chicken burrittos.
To answer this item, find first the z-score of the given data.
z-score = (x - m) / d
where x is data point, m is the mean and d is the standard deviation
Substituting the given values,
z-score = (188 - 176.7) / 9.9 = 1.14
This translates to a percentage of 87.29%.
Because we are asked of the percentage of those with height greater than this, that would be,
100 - 87.29% = 12.71%
Answer: 12.71%
Answer:
<h2>x = -7 or x = 1</h2>
Step-by-step explanation:
Answer:
1. Slope: -3/4
2. Point-slope: y+4=-3/4(x+4)
3. Slope-intercept: y=-3/4x-7
4. Standard form: 3x+4y=-28
Step-by-step explanation:
1. To find the slope, use the slope formula, which is: y2-y1/x2-x1.
Plug the y-coordinates into the top part of the equation and the x-coordinates into the bottom part.
2--4/-4-4
2+4/-8 = 6/-8, or 3/-4
2. Use the slope and one of the x and y coordinates to put the equation into point-slope form. Recall that point-slope form is: y-y1=m(x-x1). Let's use the coordinates (4,-4).
y+4=-3/4(x+4)
3. To put the point-slope equation into slope-intercept form (y=mx+b), you need to distribute -3/4 to x+4 and subtract 4 from both sides.
When you distribute, the equation becomes:
y+4=-3/4x-3
Finally, when you subtract 4, the equation becomes:
y=-3/4x-7
4. Standard form is written as x+y= #.
To convert y=mx+b to standard form, first subtract -3/4x from both sides.
-3/4x + y = -7
Multiply everything by 4
3x + 4y = -28
