Answer:
Option c
Step-by-step explanation:
Systematic sampling is a probability type of samplng method in which elements are picked from a large population at a random start point and then the others are picked by constant periodic intervals which is usually done by dividing the population size by the chosen sample size. Then do a random start between 1 and the sampling interval, then repeatedly add the sampling interval to select subsequent elements.
Counterclockwise rotation about the origin by 180 degrees, followed by a reflection over the y-axis.
The second chloce.
Answer:
(x+3)(x+7)
Step-by-step explanation:
2e^(x+3)=10
e^(x+3)=5
ln[e^(x+3)]=ln 5
(x+3)ln e=ln 5
(x+3)=ln 5
x=(ln 5)-3
Answer: x=(ln 5) - 3
Answer:
x = -3 and x = -7
Step-by-step explanation:
7 + 2(x+5) = 11
7 + 2x + 10 = 11
2x + 17 = 11
2x = -6
x = -3
7 + -2(x+5) = 11
7 + (-2x) + (-10) = 11
-3 -2x = 11
-2x = 14
x = -7
