Answer:
Step-by-step explanation:
The confidence interval gives an estimate of range of values that could possibly contain the unknown population parameter which could be the population mean or population standard deviation.
Given that the lower end of the confidence interval is 20 minutes and the upper end of the confidence interval is 58 minutes, if the population mean time customers spent on that website is 31 minutes a day, then the correct option is
C. Yes, because the population mean, mu, is included within the confidence interval estimate.
P=6 - value .01
d=12 or 2*p - value .1
n=3 - value .05
q=12 or 4*n - value .25
Multiply each denomination's value by how many she had.
(6*.01)+(12*.1)+(3*.05)+(12*.25)
.06+1.20+.15+3.00
$4.41
Answer:
14 (B)
Step-by-step explanation:
Area = L * h
L = 7 in^2
h = 2
Area = 7 * 2
Area = 14 in^2
Answer:
Part 1) ∠MJK and ∠PJR have a unequal measures
Part 2) ∠KJL and ∠MJL have a unequal measures
Part 3) ∠LJP and ∠NJR have a equal measures
Part 4) ∠MJP and ∠PJR have a equal measures
Part 5) ∠KJR and ∠MJP have a unequal measures
Step-by-step explanation:
Part 1) ∠MJK and ∠PJR
we have that
Observing the figure
∠MJK=90°
∠PJR=48°+46°=94°
therefore
∠MJK and ∠PJR have a unequal measures
Part 2) ∠KJL and ∠MJL
we have that
Observing the figure
∠KJL=42°
∠MJL=90°-42°=48°
therefore
∠KJL and ∠MJL have a unequal measures
Part 3) ∠LJP and ∠NJR
we have that
Observing the figure
∠LJP=48°+46°+48°=142°
∠NJR=48°+48°+46°=142°
therefore
∠LJP and ∠NJR have a equal measures
Part 4) ∠MJP and ∠PJR
we have that
Observing the figure
∠MJP=46°+48°=94°
∠PJR=46°+48°=94°
therefore
∠MJP and ∠PJR have a equal measures
Part 5) ∠KJR and ∠MJP
we have that
Observing the figure
∠KJR=90°+46°+48°+48°+46°=278°
∠MJP=46°+48°=94°
therefore
∠KJR and ∠MJP have a unequal measures
20%=0.20
20% of 18 is 18(0.2)=$3.6
$18-$3.6= $14.4
the discount price is $14.4
