Answer:
0
Step-by-step explanation:
We can find the slope by using
m = (y2-y1)/(x2-x1)
= (10-10)/(1-4)
= 0/-3
=0
Answer:
3
Step-by-step explanation:
<span>a)
2=(x-2.7)/.5
(2)(.5) = x-2.7
1=x-2.7
x=3.7
-2.5=(x-2.7)/.5
(-2.5)(.5) = x-2.7
-1.25 =x-2.7
x=2.7-1.25 = 1.45
b)
95% of the students' score lie within 2 standard deviation of the mean. Therefore, the top 2.5% corresponds to a z value of 2.
The limits are (2, infinity) --- top 2.5 %</span>
Y=50x+550
This is a linear equation of the form:
y=mx+b, where m=rate of change or slope and b=y-intercept.
The slope is the rate of change and the y-intercept is the value of y when x=0, which is the initial value. So in this context...
The change per week is $50.
The starting amount was $550
