Answer:
Q1 = 61
Q3 = 63
Step-by-step explanation:
From the plot attached :
Data obtained is :
Temperature frequency
59 0
60 2
61 3
62 3
63 4
64 2
65 1
Frequency Total 15
Data in raw format :
60,60,61,61,61,62,62,62,63,63,63,63,64,64,65
The first quartile :
Q1 = 1/4(n+1)th term
n = 15
Q1 = 1/4(15+1)th term
Q1 = 1/4 * 16th
Q1 = 4th term
Q1 = 61
Third quartile (Q3):
Q3 = 3/4(n+1)th term
n = 15
Q3 = 3/4(15+1)th term
Q3 = 3/4 * 16th
Q3 = (48/4)th term
Q3 = 12th term
Q3 = 63
Answer:
The slope of the line 4x – 5y = 12 is m = 4/5.
Step-by-step explanation:
To find the slope of this line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = 12 is m = 4/5.
36000 divided by 29,400 get the answer then divide by 12
Answer:
16a + 20
12a + 20 + 4a
2(8a+10)
Step-by-step explanation:
Answer:
2744 Rhinos will be left after 10 years
Step-by-step explanation:
This question has to do with exponential decay rate. We solve this using the formula:
P(t) = Po(1 - r)^t
Where P(t) = Amount left after t years
Po = Initial amount
r = Decay rate = 3.7% = 0.037
t = time in years = 10 years
P(t) = 4000(1 - 0.037)¹⁰
P(t) = 4000 × 0.963¹⁰
P(t) = 4000 × 0.6859032667003232
P(t) = 2743.6130668
Approximately = 2744 Rhinos will be left after 10 years
