hi <3
this would be false. an isosceles trapezium has one line of symmetry down the centre
hope this helps :)
Answer:
66.28% of students study more than 8 hours
Step-by-step explanation:
The percent of students study more than 8 hour can be calculated as
P(X>8)=?
P(X>8)=P((X-mean)/sd>(8-9.92)/4.54)
The calculated z-score is -0.42.
P(X>8)=P(Z>-0.42)
P(X>8)=P(0<Z<-0.42)+P(0<Z<∞)
P(X>8)=0.1628+0.5=0.6628.
Thus, 66.28% of students study more than 8 hours.
We know that
applying the law of sines
a/sin A=b/sin B---------> a*sin B=b*sin A
<span>A = 80°, a = 24, b = 50
sin B=[b*sin A]/a-----> sin B=50*sin 80/24-----> sin B=2.0517
the sines value </span><span>can not be greater than 1
hence
the answer is
zero triangles</span>
Answer:
The second and third option are both functions!!
Glad to help!!
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
1. Use sine law to solve
3/sin35 = x/sin55
3sin55/sin35 = 7
