Answer 1

x = 44°

Step-by-step explanation:

Since AB is a diameter,

arcAC + arcCB = 180

92° + arcCB = 180

arcCB = 88°

ArcCB is the intercepted arc and by definition, the inscribed angle x is half the measure of the intercepted arc. Therefore,

x = (1/2)arcCB

= 44°

A company operates three machines during three shifts each day. From production records, the data in the table below were collected. At the .05 level of significance test to determine if the number of breakdowns is independent of the shift.

Machine
Shift A B C
1 Observed 46 11 13
Expected 40.27933 14.07821 15.64246
2 Observed 37 10 11

3 Observed 20 15 16
Expected 29.34637 10.25698 11.39665

a. Yes, you can reject the claim that the number of breakdowns is independent of the shift because the p-value = 0.0423
b. Yes, you can reject the claim that the number of breakdowns is independent of the shift because the p-value = 0.9577
c. No, you cannot reject the claim that the number of breakdowns is independent of the shift because the p-value = 0.0423
d. No, you cannot reject the claim that the number of breakdowns is independent of the shift because the p-value = 0.9577

unbounded region

A feasible region that cannot be enclosed in a closed figure is known as an unbounded region. A feasible region is a set of all possible points of an optimization problem that satisfy the problem's constraints; feasible sets may be bounded or unbounded.

Step-by-step explanation:

Si compraste 0.5 mts. de alambre grueso con un costo de $ 4.00 pesos por metro y 0.4 mts. de alambre delgado con un costo de $5.00 pesos por metro,
¿Cuánto fue el costo total en la compra de los metros de alambre?

Answers

Answer:

El costo total en la compra es $4.00 pesos.

Step-by-step explanation:

El costo total en la compra de los metros de alambre viene dado por la suma de los costos de los metros individuales de los alambres gruesos y delgados:

[tex] C_{t} = C_{g} + C_{d} [/tex]

En donde:

[tex] C_{t} [/tex]: es el costo total

[tex] C_{g} [/tex]: es el costo del alambre grueso

[tex] C_{d} [/tex]: es el costo del alambre delgado

Podemos encontrar el costo de cada alambre multiplicando el valor por la cantidad de metros:

[tex]C_{g} = 0.5 m*\frac{\$ 4.00}{m} = \$2.00[/tex]

[tex]C_{d} = 0.4 m*\frac{\$ 5.00}{m} = \$2.00[/tex]

Entonces, el costo total es:

[tex]C_{t} = 2.00 + 2.00 = \$4.00[/tex]

Por lo tanto, el costo total en la compra es $4.00 pesos.

A company hopes to improve customer satisfaction, setting a goal of less than 5% negative comments. A random survey of 850 customers found only 34 with complaints. Does this provide evidence at the 10% significance level that the company has reached its goal of decreasing the percentage of complaints

Answers

Answer:

The p-value of the test is 0.0901 < 0.1, which means that this provides evidence at the 10% significance level that the company has reached its goal of decreasing the percentage of complaints.

Step-by-step explanation:

A company hopes to improve customer satisfaction, setting a goal of less than 5% negative comments.

At the null hypothesis, we test if the proportion of negative comments is of at least 5%, that is:

[tex]H_0: p \geq 0.05[/tex]

At the alternative hypothesis, we test if this proportion is less than 0.05, that is:

[tex]H_1: p < 0.05[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

0.05 is tested at the null hypothesis:

This means that [tex]\mu = 0.05, \sigma = \sqrt{0.05*0.95}[/tex]

A random survey of 850 customers found only 34 with complaints.

This means that [tex]n = 850, X = \frac{34}{850} = 0.04[/tex]

Value of the test statistic:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{0.04 - 0.05}{\frac{\sqrt{0.05*0.95}}{\sqrt{850}}}[/tex]

[tex]z = -1.34[/tex]

P-value of the test and decision:

The p-value of the test is the probability of finding a sample proportion below 0.04, which is the p-value of z = -1.34.

Looking at the z-table, z = -1.34 has a p-value of 0.0901.

The p-value of the test is 0.0901 < 0.1, which means that this provides evidence at the 10% significance level that the company has reached its goal of decreasing the percentage of complaints.

1. Determine the length of JG using
circle D.
Show your work and write out your
justification.
Be prepared to answer questions
about additional angles, arcs and
segments from circle D.

Answers

Given:

In circle D, [tex]\angle EDH\cong \angle EDG[/tex].

To find:

The length of JG.

Solution:

We know that, if two central angles are congruent then the corresponding chords are congruent and their measures are equal.

We have,

[tex]\angle EDH\cong \angle EDG[/tex]

It means chords EH and EG are congruent and their measures are equal.

[tex]EH=EG[/tex]

[tex]9=EG[/tex]

Using segment addition property, we get

[tex]EJ+JG=EG[/tex]

[tex]4+JG=9[/tex]

[tex]JG=9-4[/tex]

[tex]JG=5[/tex]

Therefore, the length of JG is 5 units.
