Answer:

(i) Five number summary: Minimum value = 1, Q_1=18,Median=18.5, Q_3=20.5, Maximum value = 26.

(ii) IQR = 2.5, upper fence = 24.25 and lower fence = 14.25.

(iii) 26 is an outlier of the data.

Step-by-step explanation:

The given data set is

19, 18, 23, 18, 18, 26, 19, 16, 20, 18, 17, 21

Arrange the data set in ascending order.

16, 17, 18, 18, 18, 18, 19, 19, 20, 21, 23, 26

Divide the data set in 4 equal parts.

(16, 17, 18), (18, 18, 18), (19, 19, 20), (21, 23, 26)

Minimum value = 16

Q_1=\frac{18+18}{2}=18

Median=Q_2=\frac{18+19}{2}=18.5

Q_3=\frac{20+21}{2}=20.5

Maximum value = 26

The inter quartile range (IQR) of the data is

IQR=Q_3-Q_1=20.5-18=2.5

Upper fence :

Q_3+1.5(IQR)=20.5+1.5(2.5)=24.25

Lower fence :

Q_1-1.5(IQR)=18-1.5(2.5)=14.25

If the any element of the data set lies out side the upper fence and lower fence, then it is called an outlier.

26 ∉ [14.25, 24.25]

Therefore, 26 is an outlier of the data.

In a right triangle, if a = 8 and c = 17, what is the correct setup to find the value of b?
salantis [7]

Answer:

b =15

Step-by-step explanation:

We can use Pythagoras theorem to find b:

a^{2}+b^{2} = c^{2}

8^{2} + b^{2} = 17^{2}

64 + b^{2} = 289

64 + 225 = 289

64 + 15^{2} = 289

b = 15

hope this helps :) and sorry if not right

What is the rate of change of the water level , in feet per hour
miskamm [114]
A; rate of change is the same as slope, so, using the slope formula, m= \frac{y_{2} - y\1_{1}   }{ x_{2} - x_{1} }, where m is the slope and x_{1}, x_{2}, y_{1}, and y_{2} are the x and y values.

Plug in 2 points for x and y, water level being the y and time being the x since we're looking for the answer in ft/hr-- you can choose any two, but from the same row.

m= \frac{ 30-50}{4-0}
m= \frac{-20}{4}
m= \frac{-5}{1}
m= -5 ft/hr
