Yes his equations are correct
Answer:
Step-by-step explanation:
In a geometric sequence, the nth term is
T_n = ar^(n-1)
a = first term
r = common ratio which can be gotten by dividing second term by first term, third term by second term etc
Therefore
a = 16
r = -3.2 ÷ 16
r = -0.2
T_7 = ar^(7-1)
T_7 = ar^6
T_7 = 16[(-0.2)^6]
T_7 = 16(0.000064)
T_7 = 0.001024
The list of scores from the given box-and-whisker plot are:
Lowest score: 20
Lower quartile (Q1): 30
Median: 60
Upper quartile (Q3): 80
Highest score: 100
The range = 80
<h3>How to Determine the Scores or Data Point from a Box-and-whisker Plot?</h3>
There are specifically 5 values that are referred to as the five-number summary which are displayed by a typical box-and-whisker plot. As shown in the image attached below, these values include the following:
- The minimum value which is the least value
- The lower quartile value (Q1)
- The median value
- The upper quartile value (Q3),
- The maximum value which is the largest data score.
Thus, from the box-and-whisker plot that is given in this question, the five-number summary are:
Minimum value (lowest score): 20
Lower quartile value (Q1): 30
Median: 60
Upper quartile value (Q3): 80
Maximum value (highest score): 100
The range = max - min = 100 - 20
The range = 80

Of course for a rectangle A = L × W and we need to be careful about the units.
Here that's
18900 sq cm = L × 180 cm
where the area's in sq cm so we converted the width. We get
L = 18900 / 180 = 105 cm
We're asked for the result in meters, so that's
Answer: 1.05 m
The perimeter of the outer rectangle is
18.4 m + 32.5 m + 18.4 m + 32.5 m = 101.8 m
Answer: 101.8 m
The area of the seating space is the big rectangle minus the small rectangle,
A = 18.4(32.5) - 15(28) = 178 sq m
Answer: 178 sq m
