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
Answer:
The correct options for the solution values are:
Step-by-step explanation:
Given the expression

Subtract 25 from both sides

Simplify

Add 25 or 5² to both sides

as

so the expression becomes


solve

Subtract 5 from both sides


solve

Subtract 5 from both sides


Therefore, the solution to the equation

Hence, the correct options for the solution values are:
Answer:
1. Never
2. Sometimes
3. Never
4. Always

If the equation is
(2 times 3^x)
Then the answer is d. (0,2)
This is because plugging x = 0 leads to y = 2 as shown below
