Answer:
m = -1
b = 5
Step-by-step explanation:
Hello!
Slope - Intercept Form: 
<h3>Slope</h3>
The slope of the line is the rate of change, or how the graph changes in y as it changes in x.
Slope can be calculated by the formula: 
We need two points on the line to get the x and y-values. I'm going to choose points (0,5) and (4,-3).
Calculate Slope
The slope is -2.
<h3>Y-intercept</h3>
The y-intercept of the line is where the graph touches the y-axis (x = 0). It can be found by looking at the intersection of the graph and the axis.
The intersection happens at point (0,5), so the y-intercept is 5.
<h3>Equation</h3>
We found m, the slope, to be -2 and b, the y-intercept, to be 5. We can just plug it into the equation format.
Equation:
Answer: 2(x+y)-25
Step-by-step explanation:
First, we need to show the sum of Roger and Olivia's heights. If Roger is x and Olivia is y, the sum is <em>x+y</em>
Next, we need to double that. To double something we multiply it by 2. Since we need double the expression we found above, we put it in parentheses. So the doubled sum is shown as <em>2(x+y)</em>
Finally, we need to show that Isabella is 25 centimeters shorter than the doubled sum. To do that, subtract 25.
The final expression for Isabella's height is 2(x+y)-25
Answer:
yes
Step-by-step explanation:
-2*(-7) = 14
Answer:
Step-by-step explanation:
Given
--- proportion that have very little confidence
--- sample
Required
Determine the probability that exactly 5 have very little confidence
This question will be solved using binomial probability:
In this case: x = 5.
So, we have:
Hello!
You first have to look and see if there is an outlier
An outlier is something that is away from the rest of the data
All the numbers are with 1 from each other so there is no outliers
The answer is the first one
Hope this helps!
