Answer:
A.) 15 ; b.) 17 ; c.) 20 ; d.) 19 ; e.) 55 ; 67; 76 ;100 ; F.) 369
Step-by-step explanation:
Let :
Cars = C ; Motorcycle = M ; Tricycle = T ; Walking = W
a) How many students ride in a tricycle, motorcycle and car going to their school
Intersection of the 3 modes;
(C n M n T) = 15 ; it is the number which sits in between all the three circles.
B.) How many students ride in both a motorcycle and a tricycle?
(M n T) = 17 ; number in the middle of both circles representing motorcycle and tricycle
C.) How many students ride in both a motorcycle and a car?
(M n C) = 20 ; number in the middle of both circles representing motorcycle and Car
D) How many students ride in both a car and tricycle?
(C n T) = 19 ; number in the middle of both circles representing Car and tricycle
e.)How many students go to school
in a car only = 55
in a motorcycle only = 67
Tricycle only = 76
Walking = 100
F.) How many Grade Seven students of Koronadal National Comprehensive High School are there in all?
(100 + 67 + 76 + 55 + 19 + 20 + 17 + 15) = 369
Answer:
6
Step-by-step explanation:
so if she has $65 and she spent 38.50 you find the difference which is $26.50 then you divide it by 4 which is 6.62 so yes your right its 6 if you round it
Answer: The answers are
(ii) The cost to attend Universal Studios increases by 1% each year,
(iii) An endangered species population is decreasing by 12% each year,
(iv) The population of a town that is growing by 5% each year.
Step-by-step explanation: We are given five functions and we are to select those which can be modelled with an exponential function.
(i) Here, height is varying with respect to time, so it will be a linear function.
(ii) Here, the cost to attend Universal Studios is increasing by 1% every year, so this will be an exponential function.
(iii) Here, an endangered species population is decreasing by 12% each year.
So, this will also be an exponential function.
(iv) Since we are considering the distance travelled by the bicycle at a constant speed of 25 mph, so this will be a linear function.
(v) Here also the population is growing by 5% each year. So, the function will be exponential.
Thus, the correct answer is second, third and fifth.
