Answer:
check: 50+160+130+20 = 360
50:160 = 5 : 16
Step-by-step explanation:et the smaller of the unknown angles be 5x and the larger of the two be 16x
so 130+20+5x+16x = 360
21x = 210
x = 10
so the two missing angles are 50° and 160°
check: 50+160+130+20 = 360
50:160 = 5 : 16
Answer: 144ft
Step-by-step explanation: Hope this help :D
Step-by-step explanation:
f(x) = 6x - 4
f(8) = 6(8) - 4
= 48 - 4
= 44
Answer:
Step-by-step explanation:
Hello!
To know what will be the resulting E(X) and V(X) of the total volume shipped, you have to add the three variables.
According to the properties of the E(X) The expected value of two variables or more independent variables is equal to the addition of the expected values of each variable: X+Y⇒ E(X+Y)= E(X) + E(Y)
In this case:
E(X₁+X₂+X₃)= E(X₁)+E(X₂)+E(X₃)= 200 + 240 + 120= 560 ft³
The same happens with the variance, if you add two independent variables, the variance of the resulting variable will be equal to the addition of the variance of each variable: X+Y ⇒ V(X+Y)= V(X)+V(Y)
In this case:
V(X₁+X₂+X₃)= V(X₁)+V(X₂)+V(X₃)= 10+13+8= 31
I hope it helps!
