Answer:
Rainfall: Continuous
Soil type: Discrete
Voting districts:Discrete
Temperature:Continuous
Elevation: Continuous
Vegetation type:Discrete
Step-by-step explanation:
Discrete data is one that involves round, definite numbers that can be determined by just counting whereas continuous data is one that involves complex numbers that are usually measured across a specific time interval. In a nutshell, we can say that discrete data is one that is counted while continuous is one that is measured.
Rainfall: This will be considered as a continuous data because it can't be counted in a definite number but can only be measured over a long period of time.
Soil type: This is Discrete because it can be counted. We can count the number of soil types we have in different areas.
Voting districts: This is Discrete because we can count the number of districts we have at any given time.
Temperature: This is Continuous because temperature cannot be counted but measured by the use of a thermometer.
Elevation: This continuous because it can't be counted as a number but measured.
Vegetation type: This is Discrete as we can count the number of places that have a particular vegetation type.
Answer: 18 cm
Step-by-step explanation:
Length means the same thing as “long” so whatever the length is, that’s how long it is. In this case, 18 cm is the length, so that’s how long it is.
Given:
The insect population function is:
Where x is the number of weeks.
To find:
The population after 4 weeks.
Solution:
The population of insect after x weeks is given by:
We need to find the population after 4 weeks.
After substituting , we get
The population after 4 weeks is 160. Therefore, the correct option is C.
Answer:
9 hours
Step-by-step explanation:
According to Newton's laws of cooling
dT/dt = -k(T - A)
Let U = T - A
dU/dT = 1
dU = dT
dt/dt = -kU
dT = -kU(dt)
dU/U = -kdt
On integration
ln(U) = -kt + C
U = Ce^-kt
T - A = Ce^-kt
T(0) = 68
T(5) = 25
68 - 20 = Ce^-k(0)
C = 48
and
25 -20 = 48e^-k(5)
5 = 48e^-5k
e^-5k = 5/48
-5k = ln (5/48)
k = - ln(5/48) / 5
k = - 0.4524
T - 20 = 48e^-0.4524t
When T = 21
21 -20 = 48e^-0.4524t
1 = 48e^-0..4524t
e^-0.4524t = 1/48
-0.4524t = ln (1/48)
t = - ln(1/48) / 0.4524
t = 8.5570
t= 9 hours ( to the nearest hour)
Answer:
I believe its A
Step-by-step explanation:
Angle K is congruent to itself doesn't really look like it helps to do anything at all except say " Angle K looks like Angle K"
