Answer:
y=400x
Step-by-step explanation:
This is because the graph rate is up 400 each time. Ex. (1,400) (2,800) (3,1200) etc
Hope this helped
Answer:
Kindly check explanation
Step-by-step explanation:
Calculate the 25th, 50th, and 75th percentiles.
b. Calculate the interquartile range.
c. Construct a boxplot. Are there any outliers?
Reordered data:
25, 40, 52, 55, 60, 70, 70, 72, 74, 75, 75, 80, 80, 85, 85, 86, 87, 90, 92, 99
25 th percentile :
1/4 (n + 1)th, tetm
n = 20
1/4(21) = 5.25th term
(5 + 6) th term / 2
= 65
50th percentile :
1/2 (n + 1)th, tetm
n = 20
1/2(21) = 10.5th term
(10 + 11) th term / 2
= 75
75th percentile:
3/4 (n + 1)th, tetm
n = 20
3/4(21) = 15.75th term
(15 + 16) th term / 2
= 85.5
Interquartile range :
Q3 - Q1
75th percentile - 25th percentile
85.5 - 65
= 20.5
25 is an Outlier

Answer:
B. 66 square inches
Step-by-step explanation:
Area of a trapezoid = (a + b)/ 2 * h
Where,
a = base a = 14 inches
b = base b = 8 inches
h = height = 6 inches
Area of a trapezoid = (a + b)/ 2 * h
= (14 + 8) / 2 * 6
= 22/2 * 6
= 11 * 6
= 66 inches ²
Area of a trapezoid = 66 inches ²
The correct answer is
B. 66 square inches
Answer: 7 miles/h and 1 miles/h
Step-by-step explanation:
With the speed of current = x + 1
Against the speed of current = x - 1
ATQ
4(x-1) = 3(x+1)
4x-4 = 3x+3
4x - 3x = 3+4
x = 7
Speed of boat = 7miles/h
Current of river = 1 miles/h
