Answer:

0.3172 rounded to the nearest tenth would be 0.3.

This is because you would first look at the number in the tenths place which is 3.

Then you would look to the number to the right to determine if you would round up or down.

If the number in the hundredths place is bellow 5, the number would remain the same, and if it were above 5, it would round up by one number.

If the number were 5, you would look to the number in the thousandths place and then go from there.

Since the number in the hundredths place is 1, then you will ignore the other numbers to the right and, you would have a result of 0.3.

Answer: 0.3171 rounded to the nearest tenth is 0.3.

Step-by-step explanation:

Follow these steps for rounding the decimal number 0.3171 to the nearest tenth (one decimal place):

Find the tenth digit, = 3 in the 0.3171. 

Find the digit immediately to the right of the tenth place. If this number is greater than or equal to 5, round up; otherwise, round down. 

= 1 in the 0.3171

Because 1 is less than 5, the tenth position digit 3 remains constant.

Remove all digits to the right of the rounding digit and rewrite the number.

As a result, 0.3171 rounded to the nearest tenth is 0.3.

Therefore , in response to the given problem of triangle, we can state that the triangles ECD and PQR

A triangle is a polygon since it has four segments and three vertices. It is one of the basic geometric forms. The title given to that of a triangle with the vertex A, B, and C is Triangle ABC. A unique planes and trapezoid in Geometric forms are discovered once the three criteria are not collinear. Quadrilateral and three corners define a triangle as a polygon. The triangle's corners are defined as the locations where its three sides converge. 180 degrees is the result of multiplying three triangle angles.

Here,

=> EC = PQ (equal side)

=> CD = PR  (equal side)

=> ED = QR (equal side)

as a result, the SSS property compares both triangles.

Answer:

Step-by-step explanation:

You want to know the translation effected by subtracting -2 from the x-coordinate, and subtracting -4 from the y-coordinate of the vertices of a triangle.

You have correctly observed that the triangle vertex (-2, 0) is translated to (0, -4) by the subtraction of the translation matrix. That is, the x-coordinate is increased by 2, moving the point 2 units to the right, while the y-coordinate is decreased by 4, moving the point 4 units down.

The translation is to the right by 2 units, and a translation down by 4 units.

Answer: 2 units right  4 units down

Answer:

a.

The 95% confidence interval for the proportion of all American adults who have a gun in their home is (0.4066, 0.4734). This means that we are 95% sure that the true population proportions of American adults who have a gun in their home is between these two values.

b.

The confidence level is the probability of the confidence interval containing the population proportion.

Step-by-step explanation:

Question a:

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 z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

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

Poll of 850 randomly selected American adults and finds that 44% of those surveyed have a gun in their home.

This means that [tex]n = 850, \pi = 0.44[/tex]

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.44 - 1.96\sqrt{\frac{0.44*0.56}{850}} = 0.4066[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.44 + 1.96\sqrt{\frac{0.44*0.56}{850}} = 0.4734[/tex]

The 95% confidence interval for the proportion of all American adults who have a gun in their home is (0.4066, 0.4734). This means that we are 95% sure that the true population proportions of American adults who have a gun in their home is between these two values.

b. Explain what is meant by 95% confidence in this context.

The confidence level is the probability of the confidence interval containing the population proportion.

1 ≤ x < 6

Step-by-step explanation:

Okay so the answer is 1 ≤ x < 6, and the way you solve it is pretty simple :)

First: Eliminate the functions of the inequality, leaving it to just being an inequality. You have to understand that the function is decreasing on its domain, so the sign will reverse itself once you take away g(x)

This should take you from having [tex]g(x^{2} )>g(5x+6)[/tex]  to having [tex]x^2<5x+6[/tex]. From here you solve the inequality to get [tex]-1<x<6[/tex], although you aren't done.

Afterwards you take into account the domain, which restricts everything to being greater than or equal to one. This means that your inequality changes to 1 ≤ x < 6.

yw and good luck w ur rsm hw haha

lmk if this was helpful :P

The solution of inequality is 1 ≤ x < 6.

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

Remove the inequality's functions, leaving it as an inequality alone.

As, the function is decreasing on its domain, the sign will change if g(x) is removed.

We have

g (x²) > g (5x+6)

x² > 5x +6

For the above equation the interval is -1 < x < 6.

The domain, which limits everything to being larger than or equal to one, is then taken into consideration.

So, the inequality is 1 ≤ x <6.

The perimeter of the considered isosceles triangle is  28.8 in. approx.

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

Considering the attached image below, which has same isosceles triangle with same measurements, we see that:

|AC| = |AB| (because perpendicular dropped leaves two congruent triangles in ABC, as ADC and ADB)

similarly, we have:

|BD| = |DC|

But |BC| = 6 =  |BD| + |DC|,

Thus, 6 = |BD| + |DC| = |BD| + |BD| =2|BD|

|BD| = 6/2 = 3 inches = |DC|

From Pythagoras theorem for triangle ADB, we get:

[tex]|AB|^2 = |AD|^2 + |BD|^2\\|AB|^2 = 11^2 + 3^2 = 121 + 9 = 130\\|AB| = \sqrt{130} \approx 11.4 \: \rm in. = |AC|[/tex]

(positive square root since |AB| is length, which is a non-negative measure).

Thus, we get:

Perimeter of the rectangle = |AB| + |BC| + |AC| ≈ 11.4 + 6 + 11.4 = 28.8 in.

The true statement

For Can A, we have:

[tex]h =8[/tex]

[tex]r = 0.5[/tex]

The volume is:

[tex]Volume = \pi r^2h[/tex]

This gives:

[tex]V_A = \pi * 0.5^2 * 8[/tex]

[tex]V_A = \pi * 2[/tex]

[tex]V_A = 2\pi[/tex]

For Can B, we have:

[tex]h =4[/tex]

[tex]r = 1[/tex]

The volume is:

[tex]Volume = \pi r^2h[/tex]

This gives:

[tex]V_B = \pi * 1^2 * 4[/tex]

[tex]V_B = \pi * 4[/tex]

[tex]V_B = 4\pi[/tex]

2x^5+y^12*x^2/3

Step-by-step explanation:

The value of π can be written with upper and lower limits as -

3.12 ± 0.062.

Significant figures of a number in positional notation are digits in the number that are reliable and necessary to indicate the quantity of something.

Given is that Helen draws a random circle, she then measures the circumference and diameter. She gets a circumference {C} of 405mm correct to 2 significant figures She gets a diameter {D} of 130mm correct to 2 significant figures.

We can write -

Circumference {C} = (405 ± 2) mm

Diameter {D} = (130 ± 2) mm

The value of π can be calculated as -

π = {C}/{D}

π = (405 ± 2)/(130 ± 2)

Now, divide the numbers without errors first -

405/130

3.12

Now, we will calculate the relative errors in each number -

2/405 = 0.004

2/130 = 0.016

Adding the relative errors -

0.004 + 0.016

0.02

Absolute error = 0.02 x 3.12 = 0.062

The value of π can be written with upper and lower limits as -

3.12 ± 0.062

Therefore, the value of π can be written with upper and lower limits as -

3.12 ± 0.062.

Step-by-step explanation:

A percentage of Bashir's commute that would be shorter than 32 minutes, to the nearest 10th is 50%.

Mathematically, the z-score of a given sample size or data set can be calculated by using this formula:

Z-score, z = (x - μ)/σ

Where:

Substituting the parameters into the z-score formula, we have;

Z-score, z = (32 - 32)/3

Z-score, z = 0/3

Z-score, z = 0

Since a commute of 32 minutes on a test has a z-score of 0, the percentage of Bahir's commute that would be shorter than 32 minutes can be calculated as follows:

P(x > 32) = P(z > 0)

P(z > 0) = 0.5

P(z > 0) = 50%.

Explanation:

The left-most rectangle spans from x = 0 to x = 2. It has base 2 and height 2, which means it has an area of 2*2 = 4 square units. Let A = 4 since we'll use it later.

The middle rectangle goes from x = 2 to x = 4. It has base 2 and height 3 (because it goes from y = 0 to y = -3). The area is B = 2*3 = 6

Draw a vertical line through 6 on the x axis. This forms the final rectangle we need. It has base 2 (because it goes from x = 4 to x = 6) and height 5. The area is C = 2*5 = 10.

The small sliver to the right of x = 6 is ignored completely.

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

Summary so far:

Those represent the areas of the rectangles from left to right. We ignore the portion to the right of x = 6.

Since rectangle B is below the x axis, we treat this as a negative area, or we subtract off this area. The positive areas of rectangles A and C are added.

So,

A-B+C = 4-6+10 = 8 is the final answer

We can write [tex]\displaystyle \int_{0}^{6}f(\text{x})d\text{x} = \boldsymbol{8}[/tex]

Answer:

Sum of all the interior angles = 900°

Each angle ≅  128.57° (rounded to the nearest hundredth)

Step-by-step explanation:

The sum of the interior angles of a polygon can easily be found by using the following formula...

Sum of all the interior angles = 180°(n - 2)  

In that formula "n" equals the number of sides a polygon has so in our case

n = 7

So now we know that the sum of all angels equals...

180°(n - 2) = 180° (7 - 2) = 180° (5) = 900°

From here we can easily find the measure of each angle since there is a rule that states that in a regular polygon all angles are equal to each other, so we just have to divide the sum of all interior angles by the number of interior angles, and so we get...

900° / 7 ≅ 128.57 (rounded to the nearest hundredth).
