Answer:
x°=60°
y°=60
Step-by-step explanation:
For triangle abd it is ab equilateral triangle which means that all sides are equal.
Total angle in a triangle =180
x+x+x= 180
3x=180
x=60°
For troangle bcd it is an isosceles triangle which means only twi sides are equal
Answer:
Step-by-step explanation:
Given that the proportion of murders with firearm is 79.2 %
Each murder is independent and there are two outcomes either with fire arm or without fire arm.
Hence X no of murders with fire arm is binomial with n = 200 and p = 0.792
q=1-0.792 = 0.208
a) Expected value of x = np
b) P(X=173) = 0.002289
Since probability is very low it can be concluded it would be unusual to observe 173 murders by firearm in a random sample of 200 murders
79.55/8.6=9.25
The answer is 9.25
