Answer:

Aubrey tip <u>$25.50</u> tip to the staff.

Step-by-step explanation:

Aubrey's dinner cost $ 85.

She tips the waitstaff 30%, percent for excellent service.

Now, to find the tip Aubrey pay to the staff.

Cost of dinner = $85.

Percent of tip = 30%.

So, to get the amount of tip:

30% of $85.

=\frac{30}{100} \times 85

=0.30\times 85

=\$25.50.

Therefore, Aubrey tip $25.50 tip to the staff.

Out of 48 job applicants, the manager chose 22 to interview. Did more than half of the applicants get an interview?
aleksandr82 [10.1K]
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.

The Arc Electronic Company had an income of 90 million dollars last year. Suppose the mean income of firms in the same industry
jok3333 [9.3K]

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
