Answer:
315
Step-by-step explanation:
No. of girls be g
No. of boys be b
g= 180
g/b = 4/3
b = 3g/4
b= 3(180/4)
b= 3*45
b= 135
.
Find b+g
= 135 + 180
= 315
Answer:
(a) 315°
(b) 3°
(c) 238°
Step-by-step explanation:
Bearings are measured clockwise from north. The triangle described is illustrated in the attachment.
<h3>(a)</h3>
The bearing of P from R is 180° different from the bearing of R from P it will be ...
135° +180° = 315° . . . . bearing of P from R
__
<h3>(b)</h3>
The bearing of Q from R is 48° more than the bearing of P from R, so is ...
315° +48° = 363°, or 3° . . . . bearing of Q from R
__
<h3>(c)</h3>
The angle QPR has a value that makes the sum of angles in the triangle equal to 180°. It is ...
180° -48° -55° = 77°
The bearing of Q from P is 77° less than the bearing of R from P, so is ...
135° -77° = 58°
As above, the reverse bearing from Q to P is ...
58° +180° = 238° . . . . bearing of P from Q
Answer:
210
Step-by-step explanation:
x = num of adults
x + 7.5x = 238
8.5x = 238
x = 28
#students = 238-x
= 210
The number of simple events in this experiment according to the probability is 16.
According to the statement
we have to find that the number of simple events in this experiment.
So, For this purpose, we know that the
Simple events are the events where one experiment happens at a time and it will be having a single outcome. The probability of simple events is denoted by P(E) where E is the event.
And according to the given information is:
Total number of coins tossed is 4.
then
the simple events become
Simple events = no. of coins * total coins tossed
Simple events = 4*4
Now solve it then
Simple events = 16.
So, The number of simple events in this experiment according to the probability is 16.
