Answer:

5.6⁻² 3.4⁻¹¹

Step-by-step explanation:

5.6⁻⁵ · 3.4⁻⁷ · 5.6³ · 3.4 ⁻⁴

= 5.6⁻⁵· 5.6³· 3.4⁻⁷· 3.4 ⁻⁴

= (5.6⁻⁵· 5.6³)· (3.4⁻⁷· 3.4 ⁻⁴)

= (5.6⁻⁵⁺³)(3.4⁻⁷⁻⁴)

= 5.6⁻² 3.4⁻¹¹

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

$\frac{1}{5}$

<u>Answer:</u>

Since the trianges are similar

then:

E = J = 90°

F = L = 65°

G = K = 180-90-65 = 25°

What is the best first step in solving -4x + 5/3 > 5/10

zavuch27 [327]

Answer:

Step-by-step explanation:

The best first step to solve this is to just subtract 5/3 from both sides so it is easier to simplify.
