Answer:
Analysis of variance
Step-by-step explanation:
The appropriate statistical tool for this is the analysis of variance. The analysis of variance, also known as the ANOVA, is a statistical method which has the ability to separate data from observed variance into various components which is then use for more tests.
The anova gives an analysis of the differences that are in the group means of a sample.
The annual premium is given as 5260$
The company pays 70 percent of the cost.
Therefore the amount that company pays is given by:
The company pays 3682 dollars.
Therefore M has to pay:
M has to pay 1578$ annually
Hence the weekly payment given that there are 52 weeks in a year is given by:
Hence mr M has to pay 30.35$ weekly for his medical insurance.
Let x be the number of student
x×30%=6
x=6÷30%
x=20
the number of students is 20

Answer:
x = 1 , -6
Step-by-step explanation:
given,
ln (x + 2) = ln (12) − ln (x + 3)
using identity of logarithm
ln (ab) = ln (a) + ln (b)
ln (a) - ln(b) = ln (a/b)
now
ln (x + 2) = ln (12) − ln (x + 3)
ln (x + 2) =
on comparing
(x+2)(x+3) = 12
x² + 5 x + 6 = 12
x² + 5 x - 6 = 0
x² + 6 x - x - 6 = 0
x(x + 6) -1 (x+ 6) = 0
(x - 1)(x + 6) = 0
x = 1 , -6
Hence, the value of x comes out to be x = 1 , -6
