Answer:

5 is the median

Step-by-step explanation:

ok the median is the middle number of a number or so whatever

so basically in this number line there are dots on top of a number saying how many times the number repeats

3 has two dots so : 3,3 and so on with the others too

3,3,4,5,5,5,6,8,8 this is what it would look like

3,3,4,5,5,5,6,8,8 as you can see 5 is the middle number of the all numbers so it is ur answer

A box contains 15 resistors. twelve of them are labelled 50ω and the other three are labeled 100ω. what is the probability that

Igoryamba

Answer : P(second resistor is 100ω , given that the first resistor is 50ω) is given by

$\frac{1}{5}$

Explanation :

Since we have given that

Total number of resistors =15

Number of resistors labelled with 50ω = 12

Number of resistors labelled with 100ω =3

Let A: Event getting resistor with 50ω

B: Event getting resistor with 100ω

Since A and B are independent events .

So,

$P(A\cap B)=P(A).P(B)$

Now, According to question , we can get that

$P(A)= \frac{12}{15}=\frac{4}{5}\\\\P(B)=\frac{3}{15}=\frac{1}{5}$

So,

$P(A\cap B)=P(A).P(B)\\\\P(A\cap B)=\frac{4}{5}\times \frac{1}{5}\\\\P(A\cap B)=\frac{4}{25}$

So, by using the conditional probability , which state that

$P(B\mid A)=\frac{P(A\cap B)}{P(A)}$

$P(B\mid A)=\frac{\frac{4}{25}}{\frac{4}{5}}\\\\P(B\mid A)=\frac{5}{25}\\\\P(B\mid A)=\frac{1}{5}$

So, P(second resistor is 100ω , given that the first resistor is 50ω) is given by

$\frac{1}{5}$

I need help plzzzzzzo

antoniya [11.8K]

Answer:

$→ {x}^{3} + 2 {x}^{2} - 9x - 18 \\ = {x}^{2} (x + 2) - 9(x + 2) \\ = (x + 2)( {x}^{2} - 9) \\ = \boxed{(x + 2)(x + 3)(x - 3)}$

<u>A. (x + 2)</u> is a factor of the polynomial.
