Answer:

12 pages

Step-by-step explanation:

3 1/2 pages = 1/3 hour

? pages = 1 hr

; Cross multiply. Multiply 1 times 3 1/2 which is 4. Then, divide 4 by 1/3.

4/1 times 3/1 which equals 12 pages.

Answer:

  x = 70

Step-by-step explanation:

The measure of the angle x° is half the sum of the intercepted arcs.

  x° = (112° +28°)/2 = 140°/2

  x° = 70°

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.

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 .

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].

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:

its B cuz there r six tetras and 2 platies so it is 6/2

Answer:

77°

Step-by-step explanation:

As we can see ABCD is a cyclic quadrilateral so opposite angles of a cyclic quadrilateral is supplementary.

< A + <B = 180° { being opposite angles of cyclic quadrilateral }

2x + 9° + 3x + 1° = 180°

5x + 10° = 180°

5x = 180° - 10°

5x = 170°

x = 170° / 5

x = 34°

Now

< A = 2x + 9°

= 2 * 34° + 9°

= 77°

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

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
