In a parallel circuit, the supply voltage is 120 V, 60 Hz. The resistance is 30 Ω and the inductive reactance is 40 Ω. What is t

kvasek [131]

Given : supply voltage = 120V;60 Hz

Inductive Reactance $(X_{L}) = 40$ Ω

The inductive reactance is given by the formula, $X_{L}=Lw$ , where L is inductance and $w$ is given by formula, $w = 2\pi(frequency)$

Apply this, we can say that, $L = \frac{X_{L}}{2\pi (frequency)} = \frac{40}{2(3.14)(60)} = 0.106157 H = 106.157 mH$

Consider the one-sided confidence interval expressions for the mean of a normal population. Round your answers to 2 decimal plac

ser-zykov [4K]

Answer: a) 0.84 b) 0.67 c) 1.28

Step-by-step explanation:

Using the standard normal distribution table for z-value , we have

(a) The value of $z_{\alpha}$ would result in a 80% one-sided confidence interval : $z_{(1-0.80)}=z_{0.20}=0.8416\approx0.84$

(b) The value of $z_{\alpha}$ would result in a 85% one-sided confidence interval : $z_{(1-0.85)}=z_{0.25}=0.6744897\approx0.67$

(c) The value of $z_{\alpha}$ would result in a 90% one-sided confidence interval : $z_{(1-0.90)}=z_{0.10}=1.2815515\approx1.28$

Angle A and B are supplementary angles. The measure of angle B is twice the measure of angle A minus 24. Find the measure of the

ivann1987 [24]

Answer:

A = 58

B = 112

Step-by-step explanation:

A + B = 180 Supplementary angles

B = 2A - 24 Given

Substitute for B in the first equation

A + 2A - 24 = 180

3A - 24 = 180 Add 24 to both sides

3A = 180 + 24 Combine the right

3A = 204 Divide both sides by 3

A = 204/3

A = 68

B = 2A - 24

B = 2*68 - 24

B = 136 - 24

B = 112
