2.4z + 1.2z = (2.4 + 1.2)z = 3.6z;
We have 3.6z - 6.5 =0.7 / +6.5;
3.6z = 7.2 / ×10;
36z = 72 / ÷36;
z = 2.

By accident, four burned-out bulbs have been mixed in with 20 good ones. Ken is replacing old bulbs in his house. If he selects

ollegr [7]

We will be using the fact that $P(A \, and \,B) = P(A) \cdot P(B)$ , where $P(A)$ is the probability that the first bulb works and $P(B)$ is the probability that the second bulb works.

The probability that the first bulb works is $\frac{20}{24} = \frac{5}{6}$ . However, when we take one out (given that the first bulb works) we now have 19 working bulbs and 4 bad ones. This means that the probability that the second bulb works is $\frac{19}{23}$ .

Now, we can find our final probability:

$\dfrac{5}{6} \cdot \dfrac{19}{23} = \boxed{\dfrac{95}{138}}$

Find the common difference for the sequence shown 1/4,5/16,3/8

Vladimir79 [104]

<span>common difference for the sequence = 1/16

cause
1/4 = 4/16
and
3/8 = 6/16

so
4/16 + 1/16 = 5/16
5/16 + 1/16 = 6/16
