Answer:

$y=-1$

Step-by-step explanation:

We get the equation $2x-y=1$ , and $x=0$ . Since we know the value of $x$ , that it is equal to 0, we can plug this into the equation for $x$ :

$2(0)-y=1$

From here, we can multiply 2 by 0 and then divide both sides by -1 to isolate $y$ and get what it's equal to.

$0-y=1$

$-y=1$

$y=-1$

Hope this helps!

Answer:

y = -1

Step-by-step explanation:

2x - y = 1

x = 0

y = ?

2(0) - y = 1

-y = 1

y = -1

andre [41]

Answer:

$\dfrac{10}{4} \ hour$

Step-by-step explanation:

Given that :

Jack had 4 hours of school.

He spent 45 minutes in the library

1/2 hour on a science lecture and;

had a lunch break of 25 minutes

The objective is to determine how much time is left for the school to get over and we are to write the answer as a fraction.

In order to do that, we will have to convert the minutes into hours,

we all know that; 60 minutes = 1 hour.

Then,

45 minutes = (45/60)hour = 3/4 hour

25/60 minutes = 1/4 hour

Therefore, the amount of time left for the school to get over is:

= $4 - (\dfrac{3}{4}+\dfrac{1}{2}+ \dfrac{1}{4})$

= $\dfrac{16-(3+2+1)}{4}$

= $\dfrac{16-6}{4}$

= $\dfrac{10}{4} \ hour$

The life, in years, of a certain type of electrical switch has an exponential distribution with an average life β=44. If 100 o

Bond [772]

Answer:

0.9999

Step-by-step explanation:

Let X be the random variable that measures the time that a switch will survive.

If X has an exponential distribution with an average life β=44, then the probability that a switch will survive less than n years is given by

$\bf P(X$

So, the probability that a switch fails in the first year is

$\bf P(X$

Now we have 100 of these switches installed in different systems, and let Y be the random variable that measures the the probability that exactly k switches will fail in the first year.

Y can be modeled with a binomial distribution where the probability of “success” (failure of a switch) equals 0.0225 and

$\bf P(Y=k)=\binom{100}{k}(0.02247)^k(1-0.02247)^{100-k}$

where

$\bf \binom{100}{k}$ equals combinations of 100 taken k at a time.

The probability that at most 15 fail during the first year is

$\bf \sum_{k=0}^{15}\binom{100}{k}(0.02247)^k(1-0.02247)^{100-k}=0.9999$
