NEED HELP ASAP <br> Factor the trinomial: x² +22x + 72. Explain your steps.
BigorU [14]

I got you, bro

Answer:

(x+4)(x+18)

Explanation

Let's factor x2+22x+72

x2+22x+72

The middle number is 22 and the last number is 72.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 22

Multiply together to get 72

Can you think of the two numbers?

Try 4 and 18:

4+18 = 22

4*18 = 72

Fill in the blanks in

(x+_)(x+_)

with 4 and 18 to get...

(x+4)(x+18)

Answer:

(x+4)(x+18)

Help binomial distributions
Ymorist [56]

We have the formula to compute the probability of having exactly k successed over n trials, given a probability p of success (and implicitly a probability 1-p of failure), which is


P(\text{k successed on n trials}) = \binom{n}{k}p^k(1-p)^{n-k}


Now, the probability of at least 3 successes is the union of the following event: exactly three successes,exactly four successes and exactly five successes.


We can compute their probability and sum them:\binom{5}{3}\left(\frac{3}{7}\right)^3\left(\frac{4}{7}\right)^2 + \binom{5}{4}\left(\frac{3}{7}\right)^4\left(\frac{4}{7}\right)^1 + \binom{5}{5}\left(\frac{3}{7}\right)^5 \approx 0.36788


So, the answer is about 36.79%

List all your possibility of outcomes (there are 36 outcomes) if you roll a dice containing numbers 1-6 two times. Determine the
Talja [164]
Check the table attached. 

The first coordinates of each pair represent the 1.roll, and the second coordinates the 2nd, roll.

All the possible outcomes are {(1, 1), (1, 2).... (6, 5), (6, 6)}, a total of 36, as can be seen in the table.

Each outcome has a chance of 1 out 36 total possible outcomes of occurring.

So the probability is 1/36=0.02778

2. Let f(x) = 2x² + 2. Find each of the following:<br> a. f(-3)<br> b. f(6)<br> c. f(-1)<br> d. f(4)
r-ruslan [8.4K]

Answer:  The answers are in the steps please look carefully.

Step-by-step explanation:

To solve for each value input the value into the function and solve to find f(x)

A. f(-3) = 2(-3)^2 + 2

   f(-3)  = 2(9) + 2

    f(-3) = 18 + 2  

    f(-3) = 20

B.      f(6) = 2(6)^2 + 2

        f(6) = 2(36) + 2

        f(6) = 72+ 2

        f(6) = 74

C.      f(-1) = 2(-1)^2 + 2

        f(-1) = 2(1)  + 2

        f(-1)=  2 + 2

        f(-1) = 4

D.     f(4) = 2(4)^2 + 2

       f(4) = 2(16)  + 2

       f(4) = 32 + 2

       f(4) = 34
