Answer:
0.02566
0.972559
Step-by-step explanation:
Given that :
Sample size (n) = 36
σ² = 6
sample variance S^2
a) greater than 9.1;
b) between 3.5 and 10.5.
The degree do freedom (df) = n - 1
S² > 9.1
P(S² > 9.1) = X² > ((n - 1) * S²) / 6
P(S² > 9.1) = ((36 - 1) * 9.1) / 6
P(S² > 9.1) = (35 * 9.1) / 6
P(S² > 9.1) = 53.083
P(X² > 53.08) = 0.02566 ( chi square distribution calculator)
b) between 3.5 and 10.5.
((36 - 1) * 3.5) / 6 ≤ S² ≤ ((36 - 1) * 10.5) / 6
20.416666 ≤ S² ≤ 61.25
Using the Chisquare distribution calculator :
P(X² > 20.42) = 0.9765
P(X² > 61.25) = 0.003941
Hence,
0.9765 - 0.003941 = 0.972559
Answer:
$ 1,946.00
Step-by-step explanation:
Average income per year=total income per month/12 months
total income=average income for first 4 months*4+ total income for 8 months
Let x represent total income total income for remaining 8 months
$1780.75=($1450.25*4+x)/12
$1780.75*12=$5,801+x
$21,369==$5,801+x
x=$21,369-$5,801
x=$15,568
The average income for the remaining eight months=x/8=$15568/8
=$1,946.00
The average income for the remaining 8 months is $ 1,946.00
Answer:
.
Step-by-step explanation:
We have been an division problem: .
We will simplify our division problem using rules of exponents.
Using product rule of exponents we can write:
Substituting these values in our division problem we will get,
Using power rule of exponents we will get,
Using product rule of exponents we will get,
Using power rule of exponents we will get,
Using quotient rule of exponent we will get,
Therefore, our resulting quotient will be .
