So for this one all you have to do is use the formular

Z*k=x

30k=8

K=4/15

Then when x=4


4/15x=4

So x=15

Hey there!

2ab + 2 / 2ab - 2

= 2(1)(3) + 2 / 2(1)(3) - 2

= 2(3) + 2 / 2(3) - 2

= 6 + 2 / 6 - 2

= 8 / 4

= 2


Therefore, your answer should be: 2


Good luck on your assignment & enjoy your day!

tigry1 [53]

Answer:

f_X(k)=\binom{4}{k}0.003^k0.997^{4-k}

Step-by-step explanation:

Recall that a <em>probability mass function</em> defined on a discrete random variable X is just a function that gives the probability that the random variable equals a certain value k

f_X(k)=P(X=k)

In this case we have the event  

“The computer will ask for a roll to the left when a roll to the right is appropriate” with a probability of 0.003.

Then we have 2 possible events, either the computer is right or not.

Since we have 4 computers in parallel, the situation could be modeled with a binomial distribution and the probability mass function

f_X(k)=\binom{4}{k}0.003^k0.997^{4-k}

This gives the probability that k computers are wrong at the same time.

The value of x  is 9.

We have :    - 25 = 7 - (5x - 13)

We have to find the value of x.

<h3>If f(x) = g(x), than what do you understand by true solution of this equation?</h3>

The true Solution of the equation is the value of x for which LHS = RHS.

For example - if  ax + b = cx + d , then

ax - cx = d - b

x = \frac{d-b}{a-c}   is the true solution of the equation.

In the question given -

- 25 = 7 - (5x - 13)

- 25 = 7 - 5x + 13

5x = 45

x = 9

Hence, the value of x for which LHS = RHS is 9.

(1/8 + 3/12) x (1 1/6-1/2)
aivan3 [116]

Answer:

1/2

Step-by-step explanation:

(1/8+3/12)×(11/6-1/2)

Using bodmas

Deal with the bracket first and it should start with the addition

1/8+3/12

Lcm of the two is 96

12+24/96

=36/96

Then move to the next bracket

11/6-1/2

Lcm is 6

11-3/6

=8/6

Bring the two answers together

36/96×8/6

=1/2
