Set J is the set that represents the numbers that Janet thinks are lucky.
J={3,7}
Set K is the set that represents the numbers that Kyle thinks are awesome!
K={2,4,6,8}
Set L is the set that represents the numbers that Lauren thinks she should write on the wall of her bedroom (with her parent’s permission, of course)!
L={0,3,5,6,7,8,9}
What is the set defined by ~(J ∪K) ?
Answer:
The correct option is;
b)
Step-by-step explanation:
a) 95% Sample CI = 152.6395 to 153.3605; Range = 0.721 Wider
90% Sample CI = 152.6975 to 153.3025; Range= 0.605 Narrower
b) Sample size ∝ 1/Error²
Therefore, increasing the sample will decrease the margin of error
c) The critical value is the value of the test statistic at the level of confidence
Variance = (Standard deviation)²
d) Point estimate is the mean or average, variation is the range or also the variance
e) Smaller samples have their relative standard deviations which does not depend on the sample size
Answer:
El indicador mencionado en el enunciado indica que la suma de los resultados de las pruebas de razonamiento cualitativo de los estudiantes dividido por la población de los estudiantes arroja ese promedio.
El promedio indica el valor "central" del indicador, no estudia la dispersión de los resultados de las pruebas, es decir, como se distribuye la colección de indicadores.

Answer:
Step-by-step explanation:
There were 1000 trees in the first year and every year new trees are getting added.
The sequence formed for the new trees every year is
Year 1 2 3
New trees 1000 200 40
We see a geometric sequence has been formed by the new trees added
Ratio of the second year and 1st year trees added =
Similarly ratio of trees added in 3rd year to 2nd year =
So there is a common ratio of
Explicit formula of a geometric sequence representing growth of the trees by
where a = number of trees grown first year
r = common ratio
n = number of years
Explicit formula showing the growth of the trees using sigma notation will be
And Formula for number of trees every year will be
Sum of the trees will be
=
=
=
= 2500
