Step-by-step explanation:
it is a right angled triangle so
with reference angle x
perpendicular (p) = 7
hypotenuse (h) = 10
so Now
sin x = p/h
sin x = 7 / 10
x = sin^-1( 7/ 10)
x = 44.42°
Rounding to nearest tenth
= 44°
Answer:
i think it is 7 i just looked it up but it might be accurate
any more help just ask :)
Answer:
The representative sample contained more girls than boys.
Step-by-step explanation:
Solution:-
- Denote the number of boys going on trip, B = 65
- Denote the number of boys going on trip, G = 95
- The total of T = 160 students are going on the trip.
- We are to randomly select a representative sample from the population of students with T = 160 students in total.
- The proportion of boys population ( p ) among the total population can be determined:
p = B / T
p = 65 / 160
p = 0.40625
- The proportion of girls population ( q ) among the total population can be determined:
q = G / T
q = 95 / 160
q = 0.59375
- For us to select a representative group of sample size ( n ) from the population of 160 student. The possibility of finding a girl on that representative group is q = 59.4 % while the possibility of finding a boy on that representative group is p = 40.6 %.
Answer: We are likely to see more girls as part of the representative group as compared to boys.
U.v = (1*-5) + (6*-2) = -5 - 12 = -17 <------- Answer
Answer:
Step-by-step explanation:
a) 300km in 5hrs = 300/5 = 60km/hr
b) $320 for 8hrs = $320/8 = $40/hr
c) 120 passengers in 4 buses = 120/4= 30 passengers in a bus
d) 50 degrees in 12 minutes = 50/12 = 4.2 degrees/minute
