No, less than half of the applicants got an interview. 1/2 of the applicants would be 24 that would need to be interviewed.
To calculate the percentage: 22/48 x 100. This gives you 45.8% got interviewed.
Answer:
x^2 -9
Step-by-step explanation:
(x + 3)(x − 3)
FOIL
first x*x =x^2
outer -3x
inner 3x
last -3*-3 =-9
Add together
x^2 -3x+3x -9
Combine like terms
x^2 -9
Price of the dining set = $785
Sales Tax = 7% of $785
Sales Tax = 0.07 x 785
Sales Tax = $54.95
Total price = $785 + $54.95 = $839.95

Answer:
0.0869
Step-by-step explanation:
The arc electronic company had an income of 90 million dollars last year.
Mean(μ) = 75 million dollars
Standard deviation (σ) = 11 million dollars
Probability that the randomly selected will earn more than arc did last year = Pr(x>90)
Using normal distribution,
Z = (x - μ) / σ
Z = (90 - 75) / 11
Z = 15/11
Z = 1.36
From the normal distribution table, 1.36 = 0.4131
Φ(z) = 0.4131
Recall that when Z is positive, Pr(x>a) = 0.5 - Φ(z)
= 0.5 - 0.4131
= 0.0869
