Answer:

The standard error is 0.0157.

The 90% confidence interval for the proportion of U.S. adults who are dissatisfied with the education students receive in kindergarten through grade 12 is (0.5042, 0.5558). This means that we are 90% sure that the true proportion of U.S. adults who are dissatisfied with the education students receive in kindergarten through grade 12 is between 0.5042 and 0.5558.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm zs[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

[tex]s = \sqrt{\frac{\pi(1-\pi)}{n}}[/tex] is the standard error.

In a Gallup survey of 1,012 randomly selected U.S. adults (age 18 and over), 53% said that they were dissatisfied with the quality of education students receive in kindergarten through grade 12.

This means that [tex]n = 1012, \pi = 0.53[/tex]

The standard error is:

[tex]s = \sqrt{\frac{\pi(1-\pi)}{n}} = \sqrt{\frac{0.53*0.47}{1012}} = 0.0157[/tex]

The standard error is 0.0157.

90% confidence level

So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].

The lower limit of this interval is:

[tex]\pi - zs = 0.53 - 1.645*0.0157 = 0.5042[/tex]

The upper limit of this interval is:

[tex]\pi + zs = 0.53 + 1.645*0.0157 = 0.5558[/tex]

The 90% confidence interval for the proportion of U.S. adults who are dissatisfied with the education students receive in kindergarten through grade 12 is (0.5042, 0.5558). This means that we are 90% sure that the true proportion of U.S. adults who are dissatisfied with the education students receive in kindergarten through grade 12 is between 0.5042 and 0.5558.

Answer:

76.93 ft^2

Step-by-step explanation:

it equals the whole circle's are divided by 2

The measure of the angle m∠1 is 31 degree and the measure of the angle m∠2 is 106 degree.

When two lines or rays converge at the same point, the measurement between them is called a "Angle."

We have:

m∠4=74° and m∠3=43°

m∠4 + m∠2 = 180

74 + m∠2 = 180

m∠2 = 106 degree

m∠3 + m∠2 + m∠1 = 180  (sum of angles in triangle is 180 degree)

43 + 106 + m∠1 = 180

m∠1 = 31 degree

Thus, the measure of the angle m∠1 is 31 degree and the measure of the angle m∠2 is 106 degree.

#SPJ2

Point 2 is 106°

Point 1 is 31°

Bit by bit clarification:

every triangle's total angle is 180

first you 180 - 74 = 106 for angle 2

angle 2 you had to use the angle two total then you add it with angle three like this 106 + 43 = 149 then you do  180 - 149 = 31 will give you your angle one

Answer:

BC = 36 ≅ (AQ+QD)

Step-by-step explanation:

1. Identify potential angles

∠Q≅90˚ so ∠B = 60˚ + 60˚ and ∠C = 30˚+30˚

2. Two isosoceles triangle

18=AB=AQ

18=CD=DQ

Answer:

[tex]2\sqrt{2} :1[/tex]

Step-by-step explanation:

This question was linked from another one regarding the lengths of the cubes, you can find it here: https://brainly.com/question/22396279

That question gave you the ratio of the lengths, which is [tex]\sqrt{2} :1[/tex]. Now in geometry, a general rule about solids is that if they are similar, the ratio of their volumes is the cube of the ratio of their edges. In a cube's case, every single cube known to mankind is similar as all the edges are the same length.

So the ratio of volumes would be [tex]\sqrt{2} ^3:1^3[/tex], which can be simplified as [tex]2\sqrt{2} :1[/tex].

Answer:

0.7558 = 75.58% probability this sale has occurred in Dallas

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Belt sold

Event B: Sold in Dallas.

Probability of belt being sold:

50% of 65%(made in Dallas)

30% of 100 - 65 = 35%(made in Phoenix). So

[tex]P(A) = 0.5*0.65 + 0.3*0.35 = 0.43[/tex]

Sold in Dallas:

50% of 65%. So

[tex]P(A \cap B) = 0.5*0.65 = 0.325[/tex]

What is the probability this sale has occurred in Dallas?

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.325}{0.43} = 0.7558[/tex]

0.7558 = 75.58% probability this sale has occurred in Dallas

Answer:

[tex]x = \frac{3}{2} [/tex]

Step-by-step explanation:

[tex] \frac{x + 6}{x + 1} = \frac{6}{2} [/tex]

[tex] \frac{6}{2} = 3[/tex]

so, the solution of the equation will be as follows:

[tex] \frac{x + 6}{x + 1} = 3[/tex]

3(x+1) = x + 6

3x + 3 = x + 6

3x - x = 6 - 3

[tex]x = \frac{3}{2} [/tex]

so, the answer will be x = 3/2

The function representing the number of bacteria present each day is

[tex]\rm f(t) = 2032(0.85)^{t}[/tex] .

A function from a set X to a set Y assigns to each element of X exactly one element of Y.

The set X is called the domain of the function and the set Y is called the codomain of the function

A bacteria population starts at 2032 and decrease by 15% everyday.

a function representing the number of bacteria present each day

[tex]\rm f(t) = 2032(1-.15)^{t}[/tex]

[tex]\rm f(t) = 2032(0.85)^{t}[/tex]

Therefore [tex]\rm f(t) = 2032(0.85)^{t}[/tex] is the correct answer .
