Step-by-step explanation:

The Pyramid would have a height of 3 units to have a volume of 15 cubic units and base area of 15 square units. The correct option is B

An equation is an expression that shows how numbers and variables are related to each other using mathematical operators.

The volume of an oblique pyramid is given by:

Volume = (1/3) * base area * height

The base area is 15 square units and the volume is 15 cubic units. If h is the height, hence:

15 = (1/3) * 15 * h

h = 3 units

The Pyramid would have a height of 3 units to have a volume of 15 cubic units and base area of 15 square units.

Answer:

the first one is (6.5,13)

the second one is (4,4)

Step-by-step explanation:

-2x-0=-13    

-2x=-13 divide -2 by -13

x=6.5

-2(0)-1y=-13

0-1y=-13

-1y=-13

13

so that gives you (6.5,13)

The value of p from the given equation is 4.5.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign \(=\\\).

The given equation is \(0.5p-3.45=-1.2\)

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

The equation can be solved as follows

\(0.5p-3.45=-1.2\)

\(0.5p= -1.2+3.45\)

\(0.5p= 2.25\)

\(p= 2.25\div0.5\)

\(p= 4.5\)

Therefore, the value of p is 4.5.

A bicycle store costs ​$3000 per month to operate. The store pays an average of ​$40 per bike. The average selling price of each bicycle is ​$80, The store must sell 75 bicycles each month to break even.

To determine the number of bicycles the store must sell each month to break even, we need to consider the costs and revenues involved.

Let's denote the number of bicycles sold each month as "x".

Costs:

The store incurs a fixed cost of $3000 per month to operate.

Variable Costs:

The store pays an average of $40 per bike, so the variable cost for x bikes would be 40x dollars.

Total Costs:

The total cost (TC) is the sum of the fixed and variable costs:

TC = Fixed Cost + Variable Cost

TC = 3000 + 40x

Revenues:

The average selling price of each bicycle is $80, so the total revenue (TR) for x bikes would be 80x dollars.

To break even, the total revenue should equal the total cost:

TR = TC

Substituting the expressions for TR and TC, we have:

80x = 3000 + 40x

Simplifying the equation:

80x - 40x = 3000

40x = 3000

x = 3000 / 40

x = 75

To find the polar coordinates (r, θ) corresponding to the Cartesian coordinates (-6, 6), we can use the following formulas:

r = √(x² + y²)

θ = arctan(y / x)

(a) For the given point (-6, 6):

x = -6

y = 6

First, let's find the value of r:

r = √((-6)² + 6²) = √(36 + 36) = √72 = 6√2

Next, let's find the value of θ:

θ = arctan(6 / -6) = arctan(-1) = -π/4 (since the point lies in the third quadrant)

Therefore, the polar coordinates of the point (-6, 6) are (6√2, -π/4).

(b) For r > 0 and 0 ≤ θ < 2:

In this case, the polar coordinates will remain the same: (6√2, -π/4).

(c) For r < 0 and 0 ≤ θ < 2:

Since r cannot be negative in polar coordinates, there are no valid polar coordinates for r < 0 and 0 ≤ θ < 2.

i) 170 students did not like any of the three types of music.

ii) 30 students liked any two types only.

iii) 36 students liked folk music but not rock music.

To solve this problem, we can use the principle of inclusion-exclusion.

Let's define the following events:

A: Liked rock music

B: Liked folk music

C: Liked classical music

We are given the following information:

|A| = 114 (number of students who liked rock music)

|B| = 50 (number of students who liked folk music)

|C| = 41 (number of students who liked classical music)

|A ∩ B| = 14 (number of students who liked both rock music and folk music)

|A ∩ C| = 15 (number of students who liked both rock music and classical music)

|B ∩ C| = 11 (number of students who liked both folk music and classical music)

|A ∩ B ∩ C| = 5 (number of students who liked all three types of music)

(i) To find the number of students who did not like any of the three types of music, we need to find the cardinality of the complement of the union of A, B, and C. Using the principle of inclusion-exclusion:

|A ∪ B ∪ C| = |A| + |B| + |C| - |A ∩ B| - |A ∩ C| - |B ∩ C| + |A ∩ B ∩ C|

|A ∪ B ∪ C| = 114 + 50 + 41 - 14 - 15 - 11 + 5 = 170

So, 170 students did not like any of the three types of music.

(ii) To find the number of students who liked any two types only, we need to find the cardinality of the symmetric difference of (A ∩ B), (A ∩ C), and (B ∩ C). Using the principle of inclusion-exclusion:

| (A ∩ B) ∪ (A ∩ C) ∪ (B ∩ C) | = |A ∩ B| + |A ∩ C| + |B ∩ C| - 2 |A ∩ B ∩ C|

| (A ∩ B) ∪ (A ∩ C) ∪ (B ∩ C) | = 14 + 15 + 11 - 2 * 5 = 30

So, 30 students liked any two types only.

(iii) To find the number of students who liked folk music but not rock music, we need to find the cardinality of B ∩ (A complement). Using the principle of inclusion-exclusion:

|B ∩ (A complement)| = |B| - |A ∩ B|

|B ∩ (A complement)| = 50 - 14 = 36

So, 36 students liked folk music but not rock music.

1. The probability of selecting exactly one tank with high-viscosity material is 0.

2. The probability of selecting at least one tank with high-viscosity material is 1.

3. The probability of selecting exactly one tank with high-viscosity material and exactly one tank with high impurities is 0.25.

1. The probability of selecting exactly one tank with high-viscosity material is calculated by the binomial distribution formula, P(X = n) = (nCx)p^x(1-p)^n-x, where n is the number of trials, x is the number of successes, and p is the probability of success. In this case, n = 4, x = 1, and p = 24/24 = 1. Therefore, P(X = 1) = (4C1)1^1(1-1)^4-1 = 0.

2. The probability of selecting at least one tank with high-viscosity material is calculated by the complement rule, P(X > 0) = 1 - P(X = 0). In this case, P(X > 0) = 1 - (4C0)1^0(1-1)^4-0 = 1.

3. The probability of selecting exactly one tank with high-viscosity material and exactly one tank with high impurities is calculated by the binomial distribution formula, P(X = n) = (nCx)p^x(1-p)^n-x, where n is the number of trials, x is the number of successes, and p is the probability of success. In this case, n = 8, x = 2, and p = 24/24 = 1. Therefore, P(X = 2) = (8C2)1^2(1-1)^8-2 = 0.25.

A kind of evolution through artificial selection is the practice of choosing creatures with desired features over several generations.

The mix of alleles found in an organism is known as its genotype. A phenotype is also the culmination of all the organism's discernible traits. In artificial selection, people choose animals or plants with favored phenotypic features for reproduction.

Since the phenotype is impacted by the genotype, the process of artificial selection alters allele frequencies throughout generations, resulting in the evolution of desirable features in offspring.

In conclusion, a kind of evolution through artificial selection is the practice of selecting creatures with desired qualities over several generations.

The area to which Zippy's Pizza makes delivery is 16·π square miles

The responses are;

Reasons:

The radius of the area that Zippy delivers pizza = 4 miles

Direction in which Empire Street runs = East to west

Direction of the route 26 route = North to south

Location of Zippy's Pizza parlor = 3 miles south of Empire street

-First Part:

The equation that represents the radius of delivery for Zippy's Pizza is given by the equation of a circle as follows;

(x - h)²+ (y - k) = r²

Where:

(h, k) = The center of the circle which is the location of Zippy's Pizza

r = The radius of the circle

Zippy's Pizza is at the center of the circular area with coordinates (h, k) = (0, 0)

r = 4 miles

-Which gives;

(x - 0)² + (y - 0)² = 4²

The equation that represent the radius is; x² + y² = 4²

-Second part:

The locations of addresses on Empire street, relative to Zippy's Pizza are given by the equation;

y = 3

Therefore, we have;

The furthest distances east and west on Empire street that can receive Zippy's Pizza delivery are given by the equation;

x² + 3² = 4²

x = √(4² - 3²) = ±√5

The furthest distances that can receive Zippy's Pizza delivery are ±√5 miles (east and west) from route 26

-Third Part:

Location of Little Cubs = 2 miles west and 4 miles north of Zippy's

The distance from Little Cubs Field to Zippy's = √((2² + 4²) = 2·√5

The distance from Little Cubs Field to Zippy's = 2·√5 miles

-Fourth Part:

The distance between Little Cubs Field from Zippy's radius of delivery, d, is found as follows;

d = 2·√5 - 4 = 2·(√5 - 2)

Therefore, d = 2·(√5 - 2) miles
