If Ethan is 3 inches taller than Daisy then this means that whatever is the height of Ethan, Daisy's height should be 3 inches shorter than that. Therefore, if Ethan's height is equal to x then, Daisy's height is equal to x - 3.

Given any undergraduate student, there is 10% chance that they will join the graduate program. In an undergraduate class of 400
nydimaria [60]

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 :

\mu=np=400\times0.10=40\\\\\sigma=\sqrt{np(1-p)}=\sqrt{400\times0.10(0.90)}=6

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 : z=\dfrac{x-\mu}{\sigma}

For x= 50 , we have

z=\dfrac{50-40}{6}=1.67

Using the standard normal distribution table , we have

P(x\geq50)=P(z\geq1.67)=1-P(z

Hence, the value i.e.closest to the probability that at least 50 students will be joining a graduate program = 5%

If 2/3p+6=7/6p what is the value of p?
ehidna [41]
The first thing to do is to clear the equation of fractions by multiplying by its LCM, which is 6 in this case.  When you do that, you will get the equation
4p + 36 = 7p.  Much easier to deal with, right? Now move the 4p over by subrtracting it: 36 = 3p, and p = 12
