Let... the smaller integer be x
Then, the larger integer is 2x+26(Two times.. =2x, 26 more... is =2x+26
Both added is 74
2x+26=74
2x=74−26
2x=48
x=24
I believe it’s is d because of the way the degrees go and the km it’s is traveling
Answer:
Probability = 0.8444
Step-by-step explanation:
To solve this problem, we need to obtain the z-value which corresponds to the probability that the mean of a sample of 84 computers would differ from the population mean by less than 1.39 months
Let x' denote the mean life of the computer.
Mean = 88 months
Variance = 81
Thus, standard deviation = √81 = 9
Thus, we obtain;
P(|x - μ| < 1.39) = P(-1.39 > x < 1.39)
For x' = - 1.39,
z = -1.39/(9/√84)
z = -1.39/0.982
z = -1.42
For x' = 1.39,
z = 1.39/(9/√84)
z = 1.39/0.982
z = 1.42
Thus, P(|x - μ| < 1.39) =
P(−1.42 < z < 1.42)
From the Z-distribution tables i attached, we obtain ;
0.92220 - 0.07780 = 0.8444
27.5
Just divide 330 and 12 because 1 dozen is 12!
