Answer:
see explaination
Step-by-step explanation:
Using the formulla that
sum of terms number of terms sample mean -
Gives the sample mean as \mu=17.954
Now varaince is given by
s^2=\frac{1}{50-1}\sum_{i=1}^{49}(x_i-19.954)^2=9.97
and the standard deviation is s=\sqrt{9.97}=3.16
b) The standard error is given by
\frac{s}{\sqrt{n-1}}=\frac{3.16}{\sqrt{49}}=0.45
c) For the given data we have the least number in the sample is 12.0 and the greatest number in the sample is 24.1
Q_1=15.83, \mathrm{Median}=17.55 and Q_3=19.88
d) Since the interquartile range is Q_3-Q_1=19.88-15.83=4.05
Now the outlier is a number which is greater than 19.88+1.5(4.05)=25.96
or a number which is less than 15.83-1.5(4.05)=9.76
As there is no such number so the given sample has no outliers
<span> 3.6/3=1.2*2=2.4 which is what 1 lb is equal to than you multiple by 34=81.6

Answer:
Step-by-step explanation:
The product of a binomial and a trinomial is
we have to simplify that
bringing the like terms together we get
hence our expression becomes
Answer:
Answer:22:37
DECIMAL: 10.38
bwcause of how the factors and dev7mals or other stuff they been added or divided 100 45 mix with the 1/2 and thus it is not equal from angles

HOPE IT HELPS!!!!!
52.25 x 0.08 = 4.18
So the tax is $4.18, and the total cost is $56.43
