Answer:
Step-by-step explanation:
el número es 4,5
es una ecuación lineal:
2x+18=27
2x=9
x=9/2
x=4,5
for the formula is
Y = starting population x (1-rate of change)^number of years
2010-2001 = 9
Y= 567 x (1-0.015)^9 = 494.89, round up to 495 people
Answer:
x = 0, x = 0.5 or 1/2 The points on the graph are ( -1/2 or -0.5,0 ) and ( 1,0 )
Step-by-step explanation:
2x^2-x-1 = -1
2x^2-x = 0
x(2x-1) = 0
x=0
x=0.5 or 1/2
Answer:
Interval scale
Step-by-step explanation:
In statistics, there are 4 types of measurement scales namely;
Nominal scales, interval scales, Ordinal scales and Ratio scales.
Now, in this question Cassidy is trying to research the impacts of eating breakfast on college students who have classes prior to 9 am.
This has to do with order as it deals with people who have breakfast before 9 a.m. It also deals with the exact differences in the various answers on the scale of 1 - 10 for each student student in the research for the 20 questions.
This is exactly what the interval measurement scale is all about interval scale deals with order and exact differences in values.
Thus, the scale used is an interval scale.
