Answer:
Option d) The data is symmetrical, showing that the majority of the monthly rainfall amounts was less than 2.01 or greater than 4 inches.
Step-by-step explanation:
Given that the amount of rainfall each month over the past four years is shown below.
The histogram appears as a reflection on the vertical line through the middle
The rainfall first is maximum then decreases gradually after minimum increases gradually so that it equals the start amount
Thus the histogram is perfectly symmetrical
It is not skewed to left or right
Option d) The data is symmetrical, showing that the majority of the monthly rainfall amounts was less than 2.01 or greater than 4 inches.
Answer: i think the answer is 39
Step-by-step explanation:
sorry this one got me
Doubling the dimensions gives us a 12 by 16 triangle. 12 X 18 = 216. because it's a triangle we need to divide it by 2. 216 / 2 = 108.
the answer is 108 inches squared

Step-by-step explanation:
Answer: it will take 10 minutes to get back to room temperature.
Step-by-step explanation:
Let us assume that the room temperature is 25 degrees. The current temperature of the soup before the decrease would be 25 + 50 = 75 degrees.
The soup drop about 5 degrees every minute. This is a linear rate. The rate at which the temperature is decreasing is in arithmetic progression. The formula for determining the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
a represents the first term of the sequence.
d represents the common difference.
n represents the number of terms in the sequence.
From the information given,
a = 75 degrees
d = - 5 degrees (it is decreasing)
n = t
We want to determine how long it will take to get back to 25 degrees, . Therefore,
25 = 75 -5 (t - 1) = 75 - 5t
5t = 75 - 25 = 50
t = 50/5 = 10 minutes
