Answer: A. 5%
Step-by-step explanation:
Given : The chance that they will join the graduate program : p=0.10
The total number of students in the class: n = 400
For this binomial situation :

We assume that this is normal distribution.
Let X be the random variable that represents the students will be joining a graduate program.
Z-score : 
For x= 50 , we have

Using the standard normal distribution table , we have

Hence, the value i.e.closest to the probability that at least 50 students will be joining a graduate program = 5%
Answer:
1) 257
2) 24^1=24
3) 47/8(Decimal: 5.875) How to: 5/1+7/8 = 40/80+7/8 = 40 + 7 / 8 <em>=</em><em> </em><em>4</em><em>7</em><em>/</em><em>8</em>
4)=920
5) =32.484
6) =33.444
7) = 4 : 1 How to: The GCF of 12 and 3 is 3 Divide both terms by the GCF, 3:
12 ÷ 3 = 4
3 ÷ 3 = 1 The ratio 12 : 3 can be reduced to lowest terms by dividing both terms by the GCF = 3 :
12 : 3 = 4 : 1
8) = 9 cups. How to: 2*3=6. so you multiply the other side (3) by 3 so 3*3=9 cups.
9) The second pack weighs more. How to: Since 45 ounces is 2.812 pounds (Formula
divide the mass value by 16) and 2.812 is less than 3 so second pack weighs more.
10) =26.6
