School meeting was attended only by sophomores, juniors, and seniors. 5/12 of those who attended were juniors, and 1/3 were seni

Veronika [31]

If $\frac{9}{12}$ of students were juniors and seniors that leaves the 36 sophomores to be $\frac{3}{12}$ or $\frac{1}{4}$ of attendees. I got $\frac{9}{12}$ by converting $\frac{1}{3} to \frac{4}{12} by multiplying it by 4$ and adding it to $\frac{5}{12}$ .

Now if 36 is $\frac{3}{12}$ of the equation that means theirs at least 36 juniors and seniors.

Lets start with seniors. there should be just over 36 of them there. Lets start by multiplying 36 by $\frac{3}{12}$ to figure out how many $\frac{1}{12}$ is.
The equation would look like this 36*(3/12)
start with 3/12. this equals .25 or $\frac{1}{4}$ .
Now multiply 36 by .25. this equals 9.

We have 9 students per $\frac{1}{12}$ of the attendees.

To get the amount of seniors add 9 to 36 $\frac{4}{12}$ because we already stated $\frac{3}{12}$ is 36.
36+9=45

Now to find the juniors add another 9 to create $\frac{5}{12}$ .
45+9=54

In total you have:
36 sophomores
54 juniors
45 seniors

The correct answer is c. There is no possible way to know how much the mean age decreases, but we know it definitely will (averages decrease as values less than the average are added to the data.) <span />

A manager records the number of hours, X, each employee works on his or her shift and develops the probability distribution belo

Reika [66]

Answer:

c. 2

Step-by-step explanation:

Given : X = No. of hours worked

No. of people work for the manager = 50

X = 3, 4 , 5 , 6 , 7, 8

P(X) = 0.1 , ? , 0.14 , 0.3 , 0.36 , 0.06

To Find : No. of people work for four hours

Solution : First understand the fact that sum of all probabilities is equal to 1

So, sum of all values of P(X) = 1

⇒ $0.1+?+0.14+0.3+0.36+0.06 = 1$

⇒ $0.96+? = 1$

⇒ $?= 1-0.96$

⇒ $? = 0.04$

So, the probability of no. of people worked for 4 hours is 0.04.

⇒P(4)=0.04

Thus , To calculate no. of people work for four hours :

$0.04\times 50$

⇒ 2 no. of people work for four hours per shift .

Kevin says that lines p and m will eventually intersect. Lines A and B intersect. Plane A contains lines p, m, and n. Line n is

ANTONII [103]

Answer:

No, because they are parallel.

Step-by-step explanation:

The lines $p$ and $m$ will not intersect, so Kevin is not correct.

It is given that planes A and B intersects. The plane A contains the line p, m and n on its plane. The lines p and m are parallel to each other. They are identical and move in the same direction.

Since the line p and m are parallel, they will not meet each other at any point because parallel lines does not intersect or meet at a point, they run parallelly along each other.

So, line p and m will not intersect.

Thus the answer is " No, because they are parallel."
