Answer:
Q= 114°
R= 37°
P= 29°
x= 37
Step-by-step explanation:
x + x-8 + 3x +3 = 180
5x -5 = 180
5x = 175
x= 37
R = x = 37°
p= x-8 = 37-8 = 29°
Q = 3x+3= 3×37+3 = 114°
Answer:
c
Step-by-step explanation:
Answer:
Pr(X >42) = Pr( Z > -2.344)
= Pr( Z< 2.344) = 0.9905
Step-by-step explanation:
The scenario presented can be modeled by a binomial model;
The probability of success is, p = 0.65
There are n = 80 independent trials
Let X denote the number of drivers that wear a seat belt, then we are to find the probability that X is greater than 42;
Pr(X > 42)
In this case we can use the normal approximation to the binomial model;
mu = n*p = 80(0.65) = 52
sigma^2 = n*p*(1-p) = 18.2
Pr(X >42) = Pr( Z > -2.344)
= Pr( Z< 2.344) = 0.9905
0-2+9=7 is the answer I think
Super easy just add 2 in front of Na H CO3(s). Your formula will be balanced.
