Answer:

Step-by-step explanation:

Both triangles are the same shape, just to different scales. In order to find out the length of side AB in triangle ABC, you have to find out the length of side PQ in triangle PQR and how much bigger than side AB is.

You can tell that sides AC and PR are similar, and 30/5 is 6. You see also that sides BC and QR are similar, and 42/7 is also 6. We have now discovered that triangle PQR is 6 times bigger than triangle ABC.

So now, to find the length of the missing side, we have to shrink side PQ by 6. 24/6 is 4. Therefore, the length of side AB is 4.

When playing roulette at the Venetian casino in Las Vegas, a gambler is trying to decide whether to bet $5 on the number 27 or t

cricket20 [7]

Answer:

Step-by-step explanation:

Given that:

To bet $5 that the outcome is any one of these five possibilities: 0, 00, 1, 2, 3.

Let Y represent the Amount of net profit

Then, Y= {-5, 30}

The probability distribution of Y is:

Y -5 30

P(Y=y) $\dfrac{33}{38}$ $\dfrac{5}{38}$

a) The expected value of X is given by:

$E[Y] =\sum y P(Y=y)= 30*\dfrac{5}{38}-5*\dfrac{33}{38}$

$=-0.39$

$= -39 \ cents$

On a bet of $5 on the number 25 we are expected to loose 24 cents.

While on a $5 bet that the outcome is any one of the numbers 0,00, or 1 we are expected to loose 39 cents.

Hence, $5 bet on the number 27 is better. Because the expected loss is less in this bet

Complete the recursive formula of the arithmetic sequence -3, -1, 1, 3,...

Strike441 [17]

Given:

The given arithmetic sequence is:

$-3,-1,1,3,...$

To find:

The recursive formula of the given arithmetic sequence.

Solution:

We have,

$-3,-1,1,3,...$

Here, the first term is -3. So, $b(1)=-3$ .

The common difference is:

$d=-1-(-3)$

$d=-1+3$

$d=2$

The recursive formula of an arithmetic sequence is:

$b(n)=b(n-1)+d$

Where, d is the common difference.

Putting $d=2$ , we get

$b(n)=b(n-1)+2$

Therefore, the recursive formula of the given arithmetic sequence is $b(n)=b(n-1)+2$ , where $b(1)=-3$ .

Y = f(x) + 3<br> describe the functions that take place

hram777 [196]

Answer:

A function can be reflected about an axis by multiplying by negative one. To reflect about the y-axis, multiply every x by -1 to get -x. To reflect about the x-axis, multiply f(x) by -1 to get -f(x).
