Answer:

127

Step-by-step explanation:

You can add 158 + 378 + 237 altogether for a total of 773

then subtract 773 from 900 for a total of 127

You can subtract 158 from 900 = 742

then subtract 378 from 742 = 364

and finally 237 from 364 = 127

Rt=R1 R2__, determined Rt when R1=100 and R2 =200?<br>R1+R2 (electronics)

zloy xaker [14]

Answer:

$R_t=300\ \Omega$

Step-by-step explanation:

Given that,

R₁ = 100 ohms

R₂ = 200 ohms

We need to find the equivalent resistance of the circuit. So,

$R_t=R_1+R_2\\\\R_t=100+200\\\\R_t=300\ \Omega$

So, the equivalent resistance is $300\ \Omega$ .

Times for an ambulance to respond to a medical emergency in a certain town are normally distributed with a mean of 450 seconds a

laila [671]

Mean = 450 sec
standard deviation = 50 sec
450-50 =400
450+50=500

Between 400 sec and 500 sec means one deviation above and one deviation below the mean, and it is 68%.

68%=0.68
0.68*288= 195.84≈196

Answer is d) 196
