Answer:
An applicant must score a minimum of 128
Step-by-step explanation:
To solve this question, we make use of the z-score formula.
Z = (X - mean)/standard deviation
Firstly, let’s list out the parameters from the question. From the question, we can deduce that:
Z = 1.5
X = ?
Mean = 110
Standard deviation =12
1.5= (X-110)/12
18 = X - 110
X = 110 + 18
X = 128
Answer:
1/3
Step-by-step explanation:
I think this is 1/3 because it is a ratio of successful outcomes to total number of outcomes..
Ex. Rolling a 6 sided dice.. you roll a 5... it would be 1/6.
Hope that makes sense.
Answer:
<u>The correct answer is </u>
<u>C. k+d=130
</u>
<u>7k = 3d</u>
<u>Number of kids Dr. Irvine see in a week is 39.</u>
Step-by-step explanation:
1. Let's review the information given to answer the question correctly:
Number of patients Dr. Irvine see in a week = 130
Radio of kids to adults = 3:7 or 3/7
Number of Kids = k
Number of adults = d
2. Let's find the equations system that should be set up to find out how many kids Dr. Irvine see
k + d = 130 (Number of patients Dr. Irvine see in a week)
Including the ratio:
7k = 3d
Replacing d:
d = 130 - k
Now substituting:
7k = 3 * (130 - k)
7k = 390 - 3k
10k = 390
k = 390/10
<u>k = 39</u>
Answer: 11, 7
11 + 7 = 18
11 x 7 = 77
