A 98% Confidence Interval For A Proportion Is Found To Be (0.47, 0.53). What Isthe Sample Proportion?A.

Answers

Answer 1

Answer:

0.50

Step-by-step explanation:

Answer 2

The sample proportion to be found for 98% confidence interval is

D. 0.50.

What is a confidence interval?

The mean of your estimate plus and minus the range of that estimate constitutes a confidence interval.

Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within if you repeat the test.

In statistics, confidence is another word for probability.

Given, Sample = (0.47, 0.53).

Confidence interval = 98%.

Therefore, The sample proportion is,

= (0.47 + 0.53)/2.

= 1/2.

= 0.5.

So, The sample proportion is 0.50.

Olivia bought some granola bars and spent at least $6.24. Write and solve an equality to find the number of granola bars she bought. Explain the real-world meaning of the solution.

Answers

Answer:

n ≥ 6.24/x

Step-by-step explanation:

Given that :

Amount spent is atleast $6.24

Let price spent = p

p ≥ $6.24

If cost of granola bar = x

The number of granola bars, n purchased will be :

n ≥ 6.24/x

Since cost of granola bar isn't given, we represent it as x.

Toni rents bowling shoes for $6. She bowls 2 games and spends a total of $22. Write and solve an algebraic equation to find the cost of each game.

Answers

Answer:

22=2x+6

Step-by-step explanation:

you subtract 6 from both sides

that leaves u with 16=2x

then divide 2 by 16 and that equals

8

so 8=x

each game costs $8

you put the 2 in front of the x in the beginning due to Toni playing 2 games while the shoes are a one time fee.

Answer:

22969.39 yd^2

Step-by-step explanation:

Alright to start, lets do the easier part of it, the sides of it. Since it is an octagonal prism, there are 8 rectangular sides to it. Each of these sides can be found with L*W, so use the given length of 15 and width of 6 to do this.

15 * 6 = 90

Since there's 8 of these:

90 * 8 = 720

Now, with the tricky part with the bases of the octagonal prism. Let's find the perimeter of the octagon, so use the top width of each of the rectangles.

6 * 8 = 48 = Perimeter

Now, here's the magic equation to avoid making this more complicated:

2(1+√2)p^2

Then plug in p

2(1+√2)48^2

(2+2√2) * 2304

(2+2.8284)*2304

4.8284*2304

11124.69...

But there's two bases so: 22249.39

Lastly, add this to the 720 from the rectangular prisms.

22249.39+720 = 22969.39

Hope that helps.

Enter the patriot equivalent to Tan (A)

Enter the ratio equivalent to cos (B)

Answers

Answer:

[tex](a)\ \tan A = \frac{5}{12}[/tex]

[tex](b)\ \cos B = \frac{5}{13}[/tex]

Step-by-step explanation:

Given

See attachment for triangles

Solving (a)

[tex]\tan(A)[/tex]

The tan of an angle is:

[tex]\tan(\theta) = \frac{Opposite}{Adjacent}[/tex]

From the given triangle.

[tex]Opposite = 5[/tex]

[tex]Adjacent = 12[/tex]

So, we have:

[tex]\tan A = \frac{5}{12}[/tex]

Solving (b)

[tex]\cos(B)[/tex]

The cos of an angle is:

[tex]\cos(\theta) = \frac{Adjacent}{Hypotenuse}[/tex]

From the given triangle.

[tex]Adjacent = 5[/tex]

[tex]Hypotenuse = 13[/tex]

So, we have:

[tex]\cos B = \frac{5}{13}[/tex]

Pls give me the hole equation

Answers

Answer:

x = 2

y = -3

Step-by-step explanation:

2x + 2y = -2, then 2y = -2 - 2x

3x - 2y = 12, then 2y = 3x - 12

so:

-2 - 2x = 3x - 12

add 2x and 12 to each side of the equation:

5x = 10

divide both sides by 5:

x = 2

2y = 3(2) - 12

2y = -6

divide both sides by 2:

y = -3

¿Qué banco es el más conveniente para financiar la vivienda familiar?

Para el banco A, tenemos;

El pago inicial = 10/100 × 200,000 = 20,000

El interés = 180.000 × 15 × 20/100 = 540.000

Importe total, A = 540.000 + 20.000 = 560.000

Para el banco B, tenemos;

El pago inicial = 20/100 × 200,000 = 40,000

El interés = 160.000 × 13 × 25/100 = 520.000

Importe total, B = 520.000 + 40.000 = 560.000

Para el banco C, tenemos;

El pago inicial = 0/100 × 200,000 = 0

El interés = 200.000 × 10 × 30/100 = 600.000

Monto total, C = 600,000 + 00 = 600,000

Por lo tanto, la familia debe seleccionar el banco A o el banco B que tenga el monto total de reembolso más bajo

Let angle ABZ be angle 1 and angle ZBC be angle 2.

Angle 1 = 85 degree

Angle 2 = 6x + 9

measure of angle ABC = 24x+4

Angle 2 = ABC - 85

6x + 9 = 24x + 4 - 85

6x - 24x = 4 - 85 - 9

-18x = -90

x = -90/-18 = 90/18 =
