2 because there is 18 squares and if you divide 18 by 2 you get 9 which is the fraction and then you just shade in the 2/9

Answer:

<em>The value of the expression for x=3 is 51</em>

Step-by-step explanation:

<u>Evaluating expressions</u>

To evaluate a given expression, we simply substitute the value of the variables and complete the operations.

The expression to evaluate is:

P=3(2+5x)

We will evaluate for x=3:

P=3(2+5*3)

The product must be done first:

P=3(2+15)=3*17=51

The value of the expression for x=3 is 51

ycow [4]

Answer:

22.5 cm

We know, that the formula for the circumference of a circle is d*pi or 2 * r * pi

So we know 45 = diameter. Meaning r = 22.5

Assume c and d function independently. for the system to function, either c or d must function.

almond37 [142]

For the "system" to function, we require that $C\cup D$ occurs (i.e. the event that either $C$ or $D$ function properly). This occurs with probability

$\mathbb P(C\cup D)=\mathbb P(C)+\mathbb P(D)-\mathbb P(C\cap D)$

but since $C$ and $D$ are independent,

$\mathbb P(C\cup D)=\mathbb P(C)+\mathbb P(D)-\mathbb P(C)\mathbb P(D)$

We're given that $\mathbb P(C^C)=0.08$ and $\mathbb P(D^C)=0.12$ , so

$\mathbb P(C\cup D)=(1-0.08)+(1-0.12)-(1-0.08)(1-0.12)=0.9904$

If $\mathbb P(C^C)=\mathbb P(D^C)=p$ , then

$\mathbb P(C\cup D)=(1-p)+(1-p)-(1-p)^2=1-p^2$
