Answer: 17.75

Step-by-step explanation:

The interquartile range(IQR) is the 3rd quartile - the 1st quartile.

How to get quartiles:

First get the median:

3.5, 10.4, 16, 21.7, 27.7

10.4, 16, 21.7

16

Then find the median of the first half of data(3.5, 10.4)

(3.5+10.4)/2 = 6.95

Then find the median of the last half of data(21.7, 27.7)

(21.7+27.7)/2 = 24.7

Then to get the IQR subtract 6.95 from 24.7 to get 17.75

Hope it helps <3

What does the line 5x + 4y = -6 look like
RoseWind [281]

Answer:

See attached photo for graph

Step-by-step explanation:

Solve the equation for y...  (that means get y by itself)

4y = -5x - 6         (subtract 5x from both sides)

y = -(5/4)x - 6/4  (divide both sides by 4)

y = -(5/4)x - 3/2      (simplify)

Now you can graph using slope-intercept method.   The y-intercept is -3/2, and the slope is -5/4

Suppose that a travel bureau claims that the trees in a forest are 83 feet tall on average, With a standard deviation of 2 feet
valentinak56 [21]

Answer:

Step-by-step explanation:

Given mean = 84,

Standard deviation = 2,

Sample 64,  

95% confidence interval: z = 1.96

Applying empirical rule , means that 95% of data fall within two standard deviations.

ME =  = 0.49

Rounding this to 0.5

CI =  83.5< mean < 84.5

Outside of this range=  x ≤ 83.5  and ≥  84.5

A circle is never a square?
Nookie1986 [14]

Answer:

never

Step-by-step explanation:

Since the area of the circle will always be a transcendental number and the area of a square has to be an integer, this can never happen in a finite number of steps. Therefore, you cannot square a circle
