TO MAKE ANGLE THAT ARE NEEDED IN CONSTUCTION

Answer:

A ≈ 62.3 ft²

Step-by-step explanation:

the area (A) of the triangle is calculated as

A = [tex]\frac{1}{2}[/tex]  product of 2 sides × angle between them , that is

A = 0.5 × 18 × 11.5 × sin37°

   = 103.5 × sin37°

   ≈ 62.3 ft² ( to the nearest tenth )

Answer: A

Using the z-distribution, it is found that the 90% confidence interval is given by: (0.6350, 0.6984).

A confidence interval of proportions is given by:

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

In which:

In this problem, we have a 90% confidence level, hence[tex]\alpha = 0.9[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.9}{2} = 0.95[/tex], so the critical value is z = 1.645.

The sample size and the estimate are given by:

[tex]n = 600, \pi = \frac{400}{600} = 0.6667[/tex]

Hence, the bounds of the interval are given by:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6667 - 1.645\sqrt{\frac{0.6667(0.3333)}{600}} = 0.6350[/tex]

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6667 + 1.645\sqrt{\frac{0.6667(0.3333)}{600}} = 0.6984[/tex]

The 90% confidence interval is given by: (0.6350, 0.6984).

Correct answer is C.

Step-by-step explanation.

Answer:

All real numbers

Step-by-step explanation:

We can start out by knowing that the domain of a graph is, the side, to side from the x axis directions.

We can see that the line continues of the graph shown, meaning it is infinite. Meaning the answer is the domain is all real numbers.

We can double check by seeing that the other options don't work or aren't enough:

[tex]x\geq 2\\and\\x\leq 2\\and\\x\geq -4[/tex]

The first wouldn't work becuase, yes that is part of the answer, but not the whole answer. The same goes for the others as well, they are on the line and are correct, but the best, and full answer is "All real numbers"

Answer:

Step-by-step explanation:

(x - 10)² is not an equation. It is in factorized form. If you do not mention the equals sign, then that is not an equation. But however, this factorized form can be converted to expanded form using  Algberaic formulae. The formulae are,

(a - b)² = a² - 2ab + b², (a + b)² = a² + 2ab + b²

According to the question,

a = x and b = 10

(x - 10)² = x² - 2 (x)(10) + 10²

             = x² - 20x + 100

x² - 20x + 100 is the expanded form of (x - 10)².

A quadrilateral is a polygon with 4 number of sides and 4 vertices. The shape of the field is either square or a rhombus.

A quadrilateral is a polygon with 4 number of sides and 4 vertices. A few examples of a quadrilateral are square, rectangle, rhombus, parallelogram, etc.

Given that ABCD represents a field, therefore, the field is a quadrilateral. Now, as the path is going between the field. And starts from A therefore, it will end at C.

Since It is the same distance from BA and BC. Therefore, it will be the diagonal of the quadrilateral. And as BA and BC are consecutive sides and are of the same length.

Hence, the shape of the field is either square or a rhombus.

Answer:

B. 6 cm

Step-by-step explanation:

[tex]\text{Take the volume of a sphere and solve for r.}\\V=\frac{4}{3}\pi r^3\\\text{We already know that the volume is 113, so substitute that value.}\\113=\frac{4}{3}\pi r^3\\\text{Divide both sides by 4/3 pi.}\\\frac{113}{\frac{4}{3}\pi}=r^3\\\text{Divide 113 by 4/3 pi.}\\r^3=26.98\\\text{For a more accessible value, round up.}\\r^3 \approx27\\\text{Take the cube root of both sides.}\\r=3[/tex]

Now that the radius is known, all we have to do is multiply it by 2 to get the diameter. Here the answer is simply 3 * 2, or 6.

Answer:

B. 6 cm

Step-by-step explanation:

You can use the formulas [tex]d=(\frac{6V}{\pi } )^{\frac{1}{3} }[/tex] or [tex]d = \sqrt[3]{\frac{6V}{\pi } }[/tex] to solve for diameter using volume. I will use the first forumla for this problem.

1. Substitute 113 for "V":

[tex]d=(\frac{6(113)}{\pi }) ^{\frac{1}{3} }[/tex]

2. Multiply in the parenthesis:

[tex]d=(\frac{678}{\pi } )^{\frac{1}{3} }[/tex]

3. Divide by pi (3.14):

678 ÷ 3.14 = 215.923567

[tex]d=215.9^{\frac{1}{3} }[/tex]

4. Apply the exponent:

d = 5.99907...

d = 6 cm
