Given the information below, write the conclusion in context. 1. H0 : The proportion of defective batteries = 0.02 2. HA : The proportion of defective batteries < 0.02 3. Z-score of observed sample = −1.23

Answers

Answer 1

Answer:

[tex] z = -1.23[/tex]

And we can calculate the p value with the following probability taking in count the alternative hypothesis:

[tex] p_v = P(z<-1.23) = 0.1093[/tex]

And for this case using a significance level of [tex]\alpha=0.05 ,0.1[/tex] we see that the p value is larger than the significance level so then we can conclude that we FAIL to reject the null hypothesis and we don't have enough  evidence to conclude that the true proportion is less than 0.02

Step-by-step explanation:

For this case we want to test the following system of hypothesis:

Null hypothesis: [tex]p =0.02[/tex]

Alternative hypothesis: [tex] p < 0.02[/tex]

The statistic for this case is given by:

[tex]z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}[/tex] (1)  

And for this case we know that the statistic is given by:

[tex] z = -1.23[/tex]

And we can calculate the p value with the following probability taking in count the alternative hypothesis:

[tex] p_v = P(z<-1.23) = 0.1093[/tex]

And for this case using a significance level of [tex]\alpha=0.05 ,0.1[/tex] we see that the p value is larger than the significance level so then we can conclude that we FAIL to reject the null hypothesis and we don't have enough  evidence to conclude that the true proportion is less than 0.02

Angle BCD = 2y

Step 2

Consider Figure 2 attached, each of the figure forms an isosceles trapezoid ABCF and DEFC.

By these properties of Isosceles Trapezoids

Lower Base Angles are CongruentUpper base angles are congruentAny lower base angle is supplementary to any upper base angle

Therefore:

123+2y+y=360

3y=360-123

3y=237

y=79 degrees

Therefore:

[tex]\angle BCD=2 X 79^\circ=158^\circ\\\angle BCD=\angle AFE=158^\circ\\\angle AFE=158^\circ[/tex]

Answers

Complete question:

Triangle A″B″C″ is formed using the translation (x + 2, y + 0) and the dilation by a scale factor of one half from the origin. Which equation explains the relationship between segment AB and segment A double prime B double prime?

A) segment a double prime b double prime = segment ab over 2

B) segment ab = segment a double prime b double prime over 2

C) segment ab over segment a double prime b double prime = one half

D) segment a double prime b double prime over segment ab = 2

Answer:

A) segment a double prime b double prime = segment ab over 2.

It can be rewritten as:

[tex] A"B" = \frac{AB}{2} [/tex]

Step-by-step explanation:

Here, we are given triangle A″B″C which was formed using the translation (x + 2, y + 0) and the dilation by a scale factor of one half from the origin.

We know segment A"B" equals segment AB multiplied by the scale factor.

A"B" = AB * s.f.

Since we are given a scale factor of ½

Therefore,

[tex] A"B" = AB * \frac{1}{2} [/tex]

[tex] A"B" = \frac{AB}{2} [/tex]

The equation that explains the relationship between segment AB and segment A"B" is

[tex] A"B" = \frac{AB}{2} [/tex]

Option A is correct

The drama club is selling tickets to their play to raise money for the show's expenses. Each student ticket sells for $4 and each adult ticket sells for $8.50. The auditorium can hold at most 79 people. The drama club must make no less than $460 from ticket sales to cover the show's costs. If 53 student tickets were sold, determine the minimum number of adult tickets that the drama club must sell in order to meet the show's expenses.

Answers

Answer:

79 people can only be in this so we have 53 kids so 53 * 4 = 212

Step-by-step explanation:

However, there is 53 kids to find how many adults you will have to do 79 - 53 which that = 26 so 26 adults were there. so 26 * 8.50 = 221.

To fine how much money they earn you will just have to add them up so

$212 + $ 221 = $433 so they didn't really earn the amount of money they really want which is $ 460.

Thus the minimum number of adult tickets that the drama club must sell in order to meet the show's expenses is 29 tickets.

Given,

The drama club is selling tickets to their play to raise money for the show's

expenses.

Each student ticket sells for $4 and each adult ticket sells for $8.50.

The auditorium can hold at most 79 people.

The drama club must make no less than $460 from ticket sales to cover

the show's costs.

If 53 student tickets were sold, determine the minimum number of adult

tickets that the drama club must sell in order to meet the show's expenses.

How to find the number of items from a total cost where each item cost is the same?

We will divide the total cost by the cost of each item.

Example:

Cost of each item = $3

Total cost = $9

Number of items = $9 / $3 = 2

We have,

Student ticket:

Cost of each ticket = $4

Number of tickets sold = 53

Total sell from student tickets sold = 53 x $4 = $212

Adult ticket:

Cost of each ticket = $8.50

Number of adult tickets sold = M

Total sell of adult tickets sold = M x $8.50

Total number of people the auditorium can hold = 79

Minimum amount to make from ticket sales = $460

The remaining amount that needs to sale from adult tickets:

= $460 - $212

= $248

The number of adult tickets sold:

M = $248 / $8.50 = 29

Thus the minimum number of adult tickets that the drama club must sell in order to meet the show's expenses is 29 tickets.

what is the range of the function shown in the graph?
a. -♾ < y < 5
b. -♾ < y < ♾
c. -♾ < y < -5
d. -5 < y < ♾

Answers

Answer:

-♾ < y < 5

Step-by-step explanation:

Range is set of all possible values for Y.

To know the range of value from graph one needs to see points on  axis beyond which the curve does not move.

Alternatively, we can say range is  the  value of y which is limiting the movement of curve beyond those limits.

Here we can see that upper point on curve is constrained at midpoint of  4 and 6 which is point 5.

Thus, upper limit is 5

which can be written as

y<5

___________________________________

For lower limit , it

Since , the at lower end curve is extended till the end of graph and the end of graph represents infinity. Also, this infinity is on the negative side of y .

Then lower end is -♾ .

which can be written as

y> -♾

Also we can see that graph is continuous one as there is no break in the curve between 5 and -♾.

Thus range of curve is from minus infinity to 5

which can be expressed as

-♾ < y < 5
