Answer:

The 93% confidence interval of the true proportion of people who watched educational TV

(0.73716 , 0.80684)

Step-by-step explanation:

Step(i):-

Given sample size 'n' = 145

A random sample of 145 people, 112 said that they watched educational TV.

Sample proportion

                         [tex]p^{-} = \frac{112}{145} = 0.772[/tex]

Step(ii):-

The 93% confidence interval of the true proportion of people who watched educational TV

[tex](p- Z_{0.07}\sqrt{\frac{pq}{n} } , p + Z_{0.07} \sqrt{\frac{pq}{n} } )[/tex]

[tex](0.772- 1.427\sqrt{\frac{0.772X0.228}{145} } , 0.772 + 1.427 \sqrt{\frac{0.772X0.228}{145} } )[/tex]

( 0.772 - 0.03484 , 0.772 + 0.03484)

(0.73716 , 0.80684)

Final answer:-

The 93% confidence interval of the true proportion of people who watched educational TV

(0.73716 , 0.80684)

Using translation concepts, it is found that:

The graph of g(x) is a translation of f(x) 2 units down.

---------------------------------------------

Translating a function f(x) a units down is the same as finding f(x) - a.

---------------------------------------------

In this question:

Thus, g(x) is f(x) translated 2 units down, and the correct option is:

The graph of g(x) is a translation of f(x) 2 units down.

Answer:

x = 10

y = 5

Step-by-step explanation:

Since, two lines p and q are the parallel lines and FA is a transversal line intersecting these parallel lines.

ΔAOB and ΔDOC are the similar triangles.

Therefore, by the property of similar triangles, corresponding sides of the similar triangles will be proportional.

[tex]\frac{AO}{OD}= \frac{OB}{OC}[/tex]

[tex]\frac{x}{15}= \frac{8}{12}[/tex]

x = [tex]\frac{15\times 8}{12}[/tex]

x = 10

Similarly, triangles AOB and OEF will be similar.

And by the property of similar triangles,

[tex]\frac{AO}{OF}= \frac{OB}{OE}[/tex]

[tex]\frac{x}{15+y}= \frac{8}{12+4}[/tex]

[tex]\frac{10}{15+y}= \frac{8}{16}[/tex]

8(15 + y) = 160

120 + 8y = 160

8y = 160 - 120

8y = 40

y = 5

Answer:

£27

Step-by-step explanation:

From the above question, we know that:

The price of a shirt is usually = £45. During a sale the prices in the shop are reduced by 2/5 .

Hence, the amount that the cost of tht shirt is reduced by is :

£45 × 2/5

= £18

The cost of this shirt in the sale is calculated as:

£45 - £18

= £27

Answer:

-18y =1

It is simple addition

Step-by-step explanation:

sin²x = 2 - 2cosx

1 - cos²x = 2 - 2cosx (because sin²x + cos²x = 1)

cos²x - 2cosx + 1 = 0

(cosx - 1)² = 0

cosx - 1 = 0

cosx = 1

Hence x = 0.

Answer:

44

Step-by-step explanation:

44÷5 is 8.8 which is greater than 7

Answer:

x=44

Step-by-step explanation:

Divide each number by 5

-44/5 = -8.8

34/5 = 6.8

44/5=8.8

-34/5=-6.8

8.8 is the only one greater than 7 so 44 is the only one that satisfies the inequality

Answer:

108 degrees

Step-by-step explanation:

From the diagram we are given

Interior angles are 2x + 1 and 63 degrees

Exterior angle = 5x -2

The sum of interior angles is equal to the exterior angle

2x + 1 + 63 = 5x - 2

2x + 64 = 5x - 2

2x - 5x = -2-64

-3x = -66

x = -66/-3

x = 22

Get the exterior angle:

Exterior angle = 5x-2

Exterior angle = 5(22) - 2

Exterior angle = 110-2

Exterior angle  = 108 degrees

Hence the measure of the exterior angle is 108 degrees

Answer: 6 purple rectangles

Step-by-step explanation: We know that each scarf will have 5 rectangles and 2/5 of the rectangles will be purple: 2/5 * 5 = 2. It means that each scarf will have 2 purple rectangles. And for 3 scarves : 3 * 2 = 6. Answer: She needs 6 purple rectangles.

Answer:

120ways

Step-by-step explanation:

This question bothers combination. Combination has to do with selection.

Given

Total number of brands = 10

If we the service is to rank the top 3, this can be done in 10C3 number of ways.

10C3 = 10!/(10-3)!3!

10C 3 = 10!/7!3!

10C3 = 10*9*8*7!/7!3!

10C3 = 10*9*8/6

10C3 = 720/6

10C3 = 120

Hence it will take 120ways for the consumer testing service to arrive at the final ranking

Answer:

x ^2+x-3

Step-by-step explanation:

Answer:

I believe it is 6 days.

The total number of days all crew needs to pour concrete is 6 days consecutive.

What information do we have?

Total number of crew = 3

Total yards = 175,000

Each crew pour concrete per hour = 1200

Total concrete pour per day = 1200 × 3 × 8

Total concrete pour per day = 28,800 yard

Total number of days crew pours concrete = Total yards / Total concrete pour per day

Total number of days crew pours concrete = 175,000 / 28,800

Total number of days crew pours concrete = 6.076

Total number of days crew pours concrete = 6 days

Answer:

m = 1/3 and b = - 4

Step-by-step explanation:

The equation already gives the answer as the equation is in slope-intercept form.

[tex]y = mx + b[/tex]

Where m = slope and b = y-intercept.

From the equation —

[tex]y = \frac{1}{3} x - 4 \\ m = \frac{1}{ 3} \\ b = - 4[/tex]

Therefore, our slope is 1/3 and y-intercept is - 4.
