What equashion can be used to find two numbers those ratio are 3 to 2 and have the sum of 35
Tems11 [23]

We need to set up a system, rather than a single equation, because there are two variables involved.

The first equation represents the fact that the two numbers are in a 3:2 ratio:

\dfrac{x}{y}=\dfrac{3}{2} \iff x=\dfrac{3}{2}y

The second equation represents the fact that their sum is 35:

x+y=35

So, we have the following system:

\begin{cases}x = \dfrac{3}{2}y\\x+y=35\end{cases}

Using the expression for x in the first equation, the second one becomes

x+y=35 \iff \dfrac{3}{2}y+y=35 \iff\dfrac{5}{2}y=35 \iff 5y=70 \iff y = 14

which implies

x=35-y=35-14=21

Set his alarm with a probability of 0.10. If he sets the alarm, it will wake him on time to make his first class with a probabil
Tomtit [17]

Answer:

C) 0.880

B) 0.075

Step-by-step explanation:

If the professor forgets to set the alarm

Probability = 0.1,

Wakes up in time probability = 0.25.

If the professor sets the alarm

Probability = 1 - 0.1 = 0.9

Wake up in time probability = 0.95.

A.)

The probability that professor Moore wakes up in time to make his first class tomorrow

Probability = ( Forgets to set alarm probability x Wakes up in time )+ ( Sets the alarm probability x Wakes up in time ) = ( 0.1 x 0.25 ) + ( 0.9 + 0.95 ) =  0.88

B.)

Late in the class

Set the Alarm Probability = 0.1

Wakes up late probability = 1 - 0.25 = 0.75

Professor Sets the alarm probability = Set the Alarm Probability x Wakes up late probability  = 0.1 x 0.75 = 0.075
