In a parallel circuit, ET = 120 V, R = 30 Ω, and XL = 40 Ω. What is IR?

soldi70 [24.7K]

Answer:

Step-by-step explanation:

Given

ET = 120 V

, R = 30 Ω,

XL = 40 Ω.

To find = IR=?

as in circuit inductor and resistor are parallel so ET =EL = ER = 120V

IR = current through resistor = IR = ER/ R

= 120V /30Ω.

= 4 ampere.

Which expression is equivalent to 24x2 - 22x + 5?

enot [183]

Answer:

Step-by-step explanation:

Given

24x² - 22x + 5

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 24 × 5 = 120 and sum = - 22

The factors are - 12 and - 10

Use these factors to split the x- term

24x² - 12x - 10x + 5 ( factor the first/second and third/fourth terms )

= 12x(2x - 1) + 5(2x - 1) ← factor out (2x - 1) from each term

= (12x - 5)(2x - 1) ← in factored form → C

The accompanying table describes results from groups of 8 births from 8 different sets of parents. The random variable x represe

insens350 [35]

Using the discrete probability outputs given in the attached table ; the probability values of having exactly 6 ; and having 6 or more girls are :

P(X = 6) = 0.111

P(X ≥ 6) = 0.1

The probability of having exactly 6 girls can be defined as :

P(X = 6) = 0.111 (from the discrete probability table)

2.)

The probability of having 6 or more girls can be defined as :

P(X ≥ 6) = P(X = 6) + P(X = 7) + P(X = 8)

From the table attached :

P(X ≥ 6) = 0.111 + 0.014 + 0.003 = 0.1

Therefore, the probability of having exactly 6 girls is 0.111 while the probability of having 6 or more girls is 0.1
