Each person in a group of college students was identified by graduating year and asked when he or she preferred taking classes:

swat32

Answer:

Step-by-step explanation:

The frequency table is attached below.

We have to calculate, the probability that the student preferred morning classes given he or she is a junior.

i.e $P(\text{Morning }|\text{ Junior})$

We know that,

$P(A\ |\ B)=\dfrac{P(A\ \cap\ B)}{P(B)}$

So,

$P(\text{Morning }|\text{ Junior})=\dfrac{P(\text{Morning }\cap \text{ Junior})}{P(\text{Junior})}$

Putting the values from the table,

$\dfrac{P(\text{Morning }\cap \text{ Junior})}{P(\text{Junior})}=\dfrac{\frac{16}{143}}{\frac{26}{143}}=\dfrac{16}{26}=0.615$

A submarine dives 300 feet every 2 minutes, and 6,750 feet every 45 minutes. Solve for A and

Gelneren [198K]

A: To find the rate in feet per minute, we can use the information given.
Every two minutes, the submarine dives 300 feet. So
$\frac{300feet}{2minutes} = 150 \frac{feet}{minute}$ .
In order to confirm that our rate is correct, we can use the second set of information given.
$\frac{6750feet}{45minutes}$ = $150 \frac{feet}{minute}$ .
Since we know that the rate is 150 feet per minute, we can multiply it by any number of minutes and get the answer of how deep the submarine is. We can use a variable x to represent the number of minutes and y to represent the depth in feet.
$y=150x$
There's our equation.
B: It would be more reasonable to use an equation with the rate feet per minute because it is more accurate since the time interval isn't too big.

Step-by-step explanation:

Since this is not factorable, let's just complete the square:

$x^2+6x=19\\x^2+6x+9=28\\(x+3)^2=28\\x+3=\sqrt{28}\\x=2\sqrt{7}-3$
