Answer:
2.1
Step-by-step explanation:
Given :
Radios(X):_0 ___ 1 ___2 ___ 3 ___4 ___5
P(X=x) : 0.03 0.20 0.50 0.20 0.05 0.02
The expected weekly radio sales :
Σ(X) * p(x) : (0*0.03) + (1*0.20) + (2*0.50) + (3*0.20) + (4*0.05) + (5* 0.02) = 2.1
Hence, expected weekly radio sale = 2.1
130
srv is a straight line so angleSRV=180
TRV and SRT make up SRV so TRV + SRT = SRV.
(x-10) + (2x+10) = 180.
the 10s cancel each other out so 3x = 180
so x=60 bc 180/3=60. sub 60 for x in TRV and u get 130. sub 60 for x in SRT and you get 50, which, with 130 makes 180, so the answer is correct!
Answer:
16
Step-by-step explanation:
So if 4 numbers have an average of 14, that means to find the sum of all 4 numbers, you work backwards & multiply 4x14 to get 56.
Then 56-the sum of the 3 numbers you already have (11+12+17=40)
56-40=16
To double check, to find the average of 4 numbers that total 56, you divide 56 by 4 & get 14
The difference between a blue whale's heart and a African bull elephant heart is 2963.27 lbs. it will take 49 African bull elephant's heart to equal one blue whale's heart.
F is increasing, there are no jumps: if there's a jump from an a to a b
then one of the endpoints would be a limit point of F(S)
