Answer:
Step-by-step explanation:
Let x be the random variable representing the lifespan of laptops. Since the lifespans are normally distributed and population mean and population standard deviation are known, we would apply the formula,
z = (x - µ)/(σ/√n)
Where
x = sample mean
µ = population mean
σ = standard deviation
n = number of samples
From the information given,
µ = 24.5
σ = 2.6
n = 33
the probability that the mean lifespan of these laptops will be less 23.8 months is expressed as
P(x ≤ 23.8)
For x = 23.8
z = (23.8 - 24.5)/(2.6/√33) = - 1.55
Looking at the normal distribution table, the probability corresponding to area on the left of the z score is 0.061
P(x ≤ 23.8) = 0.061
Answer:
Correct answer: C (6.5 , - 8)
Step-by-step explanation:
Given points A(-1,-2) and B(9, -10)
The formula by which we calculate the coordinates of a point, let be C, that divides the line segment in the given ratio is.
Xc = (Xa + λ · Xb) / (1 + λ) and Yc = (Ya + λ · Yb) / (1 + λ)
Where λ is the coefficient which depends on the direction of the ratio in this case is:
λ = 3 : 1 = 3
Xc = (-1 + 3 · 9) / (1 + 3) = (-1 + 27)/ 4 = 26 / 4 = 6.5
Xc = 6.5
Yc = (-2 + 3 · (-10) / (1 + 3) = (-2 - 30)/ 4 = -32 / 4 = - 8
Yc = - 8
