Answer:

  (c)  115.2 ft³

Step-by-step explanation:

The volume of a composite figure can be found by decomposing it into figures whose volumes are easy to compute. Here, the figure can be nicely represented as a cube and a square pyramid.

__

The volume of the cube on the left is given by ...

  V = s³

  V = (4.2 ft)³ = 74.088 ft³

__

The volume of the pyramid on the right is given by ...

  V = 1/3Bh . . . . . where B is the area of the square base

  V = 1/3(s²)h = (4.2 ft)²(7 ft) = 41.16 ft³

__

The volume of the composite figure is the sum of these volumes:

  cube volume + pyramid volume = 74.088 ft³ +41.16 ft³ = 115.248 ft³

The volume of the composite figure is about 115.2 ft³.

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.

The Snack Shop

Step-by-step explanation:

The equation given, y=1.25x means this store sells a bar of granola for $1.25.

The other store sells their granola bar for $1.30.

1.25 is less than 1.30.

Hence, the snack shop sells their granola bars for a lower price.

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).

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.

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:

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

Answer:

C ∪ D = (-∞, 2] ∪ (7, ∞)

C ∩ D = Ø  (empty)

Step-by-step explanation:

C ∪ D:  The union of two sets or intervals is the set of elements which are in either set.  

C ∩ D:  The intersection of two sets or intervals is the set of elements which are in both sets.

Interval notation symbols

Square brackets [ ]: both endpoints are included in the set.

Round brackets ( ): both endpoints are excluded in the set.

Round, square ( ]: left endpoint is excluded and right endpoint is included in the set.

Square, round [ ): left endpoint is included and right endpoint is excluded in the set.

Given:

Therefore,

Therefore,  C ∪ D = (-∞, 2] ∪ (7, ∞)

As x is either equal to or less than 2, or greater than x, there are no elements which are in both sets.

Therefore,  C ∩ D = Ø  (empty)
