a. Taylor's approach is different from Tash's by adding the numbers in the parenthesis first.

b.  I noticed that Tash and Taylor both end with the same answer

c. 7(x) + 7(2)

Step-by-step explanation:

b. Taylor = 5(9 + 2) = 5(11) = 55

    Tash = 5(9 + 2) = 5(9) + 5(2) = 45 + 10 = 55

The height of Jane's shadow who is 5.9 feet tall is appoximately 6.3 feet

Given that, a tree 54 feet tall casts a shadow 58 feet long and Jane is 5.9 feet tall.

To find the height of Jane's shadow, we can use proportions and ratios.

Hence:

(Height of the tree) : (Length of the tree's shadow) = (Height of Jane) : (Length of Jane's shadow)

Plug in:

Height of the tree = 54

Length of the tree's shadow = 58

Height of Jane = 5.9

Let Length of Jane's shadow = x

54 feet : 58 feet = 5.9 feet : x

54/58 = 5.9/x

Cross multiply:

54 × x = 58 × 5.9

54x = 342.2

x = 342.2/54

x = 6.3 feet

Therefore, the measure of her shadow is approximately 6.3 feet.

The final value for each expression is presented: -4, -4, 6 and 6, respectively.

Here it is important to remember the rules for the  addition of integers numbers:

+  +   Add  Final result (+) - Final result (+)  

-   -   Add  Final result (-) - Final result (-)  

+  -   Subtract - Final result (the sign of the integer having a greater value)

Answer:

Answer: 51.3∘ and 128.7∘

Step-by-step explanation:

In ΔUVW, w = 5.3 inches, v = 3.6 inches and ∠V=32°. Find all possible values of ∠W, to the nearest 10th of a degree.

We solve the above question using sine rule formula. This is given as:

w/sin W = v/sin V

w = 5.3 inches

v = 3.6 inches

∠V=32°.

5.3/sin W = 3.6/sin 32

Cross Multiply

sin W × 3.6 = 5.5 × sin 32

sin W = 5.5 × sin 32/3.6

W = arc sin (5.5 × sin 32/3.6)

W = 51.28° or 128.72°

Kirk must earn an annual rate of return of approximately 6.07% on his investment to accumulate enough money to pay for the ring.

To calculate the annual rate of return Kirk must earn on his investment, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
where:
A = final amount (the cost of the ring, which is $13,000 in 9 years)
P = initial amount (the amount Kirk currently has, which is $4,532)
r = annual interest rate (what we need to solve for)
n = number of times interest is compounded per year (assuming it's compounded annually, n = 1)
t = number of years (9 years)

Plugging in the given values:
$13,000 = $4,532(1 + r/1)^(1*9)
Next, simplify the equation:
(1 + r)^(9) = 13000/4532
Take the ninth root of both sides:
1 + r = (13000/4532)^(1/9)
Solve for r:
r = (13000/4532)^(1/9) - 1
Now, plug the value into a calculator to find r:
r = 0.0607

A survey is taken at a movie theater in Wayside. The first 200 people who entered the theater were asked about their favorite type of movie. The true about this situation is: The population is the total number of people who go to the movie theater, and the sample is the first 200 people at the theater.

In this situation, the population refers to the entire group of people who go to the movie theater in Wayside. The population includes all individuals who have the potential to be surveyed about their favorite type of movie.

The sample, on the other hand, is a subset of the population and represents the first 200 people who entered the theater. These 200 individuals are selected to provide information about the preferences of the larger population.

It is important to note that the sample is not the entire population but rather a smaller representative group. By surveying the sample, we aim to gather insights and make inferences about the preferences of the larger population of moviegoers in Wayside.

The correct answer is: The population is the total number of people who go to the movie theater, and the sample is the first 200 people at the theater.

The dimensions of the rectangle is 25m × 25m.

Two dimensions make up a rectangle: the length and, perpendicular to that, the breadth.

The three dimensions of a three-dimensional shape are length, width, and depth.

It is given that

Perimeter of the rectangle = 100m

Area is as large as possible if both the values are the same number.

The measurements must be equivalent for the rectangle to attain its maximum area.

Consider the dimensions as x

So perimeter can be written as

2 (x + x) = 100

2 (2x) = 100

By additional computation

4x = 100

Divide both sides by 4

x = 25

Therefore, the dimensions of a rectangle is 25m × 25m.

Any measure can be thought of as comprising two components: the numerical value or quantity being measured, and the unit of measurement.

Any measure can be understood as having two components: the numerical value or quantity being measured, and the unit of measurement. The numerical value represents the quantity or magnitude of what is being measured. For instance, if we measure the mass of an object, the numerical value would represent the amount of mass, such as 5 kilograms.

The unit of measurement, on the other hand, provides the scale or standard against which the quantity is measured. In the previous example, the unit of measurement is kilograms, which is the standard unit for measuring mass.

Together, these two components form a complete measure, allowing us to quantify and compare different attributes or properties of objects. It is essential to specify both the numerical value and the unit of measurement to provide meaningful information and ensure accurate communication of measurements.

There are 28 ways to choose 6 teams for the playoffs if there are 8 college basketball teams in a certain sub-division.

To determine the number of ways to choose 6 teams for the playoffs out of the 8 college basketball teams in a certain Sub-Division, we can use the combination formula. The formula for combinations is given by

nCr = n! / (r! * (n-r)!),

where n represents the total number of teams and r represents the number of teams to be chosen.

In this case, n = 8 and r = 6.

Plugging in these values, we have

8C6 = 8! / (6! * (8-6)!) = 8! / (6! * 2!) = (8 * 7) / (2 * 1) = 28.

Therefore, there are total 28 ways to choose 6 teams.

Papers do you expect to hand in before you receive each possible grade at least once is 14.7.

given,

Total number of grades= 6

Imagine Y to be number of papers till we get all grades once. Hence

Yi= Number of papers till we get i th newer grades

Expected value of Y₆= ?

The difference between getting a new grade maybe represented as

Xi= Yi+1 - Yi

Using above equation for Y₆, we get

[Y₆]= ∑⁵i=o Xi

which means, we need to get 5 different grades from the first grade.

Number of tries to see second new grade maybe represented as

X₁= {(6-1)/6}, which, for generalization is written as Xi=geo{(6-i)/6}

Xi represents the success probability of seeing further new grade.

Expected value of Xi is inverse of parameter of geometric distribution, which is,

[Xi] = 6/(6-i) = 6.{1/(6-i)}

Expected value of Y₆= [∑⁵ i=0 Xi] = ∑⁵ i=0 [Xi]

Substituting value of [Xi] in the above expression

6.∑⁵i=0 {1/(6-i)} = 6. ∑⁶i=1 (1/i)

Now solving for 6 grades

Y₆ = 6[(1/6) + (2/6) + (3/6) + (4/6) + (5/6) + (6/6)]

Y₆ = 6 x 2.45 = 14.7

The terms syllabic, melismatic, and neumatic are all related to the number of notes in relation to each syllable of a text. Syllabic means that each syllable of the text is sung to one note.

This is the simplest type of setting for text to music. In contrast, melismatic means that each syllable of the text is sung to many notes, creating a more intricate and ornamental melody. Neumatic is somewhere in between syllabic and melismatic, where each syllable is sung to a few notes, but not as many as in a melismatic setting.

Answer:

A, B, E, and F

Step-by-step explanation:

The solution of the given system of equations is x = -4, y = 5 and z = 2 is the answer.

The system of equations given below:x + 2y + 3z = 11;2x + 4y + 5z = 21;3x + 5y + 6z = 27.

Here, we will solve this system of equations using inverse of the matrix method as follows:

We can write the given system of equations in matrix form as AX = B where, A = [1 2 3; 2 4 5; 3 5 6], X = [x; y; z] and B = [11; 21; 27].

The inverse of matrix A is given by the formula: A-1 = (1/ det(A)) [d11 d12 d13; d21 d22 d23; d31 d32 d33]  where,

d11 = A22A33 – A23A32 = (4 × 6) – (5 × 5) = -1,

d12 = -(A21A33 – A23A31) = -[ (2 × 6) – (5 × 3)] = 3,

d13 = A21A32 – A22A31 = (2 × 5) – (4 × 3) = -2,

d21 = -(A12A33 – A13A32) = -[(2 × 6) – (5 × 3)] = 3,

d22 = A11A33 – A13A31 = (1 × 6) – (3 × 3) = 0,

d23 = -(A11A32 – A12A31) = -[(1 × 5) – (2 × 3)] = 1,

d31 = A12A23 – A13A22 = (2 × 5) – (3 × 4) = -2,

d32 = -(A11A23 – A13A21) = -[(1 × 5) – (3 × 3)] = 4,

d33 = A11A22 – A12A21 = (1 × 4) – (2 × 2) = 0.

We have A-1 = (-1/1) [0 3 -2; 3 0 1; -2 1 0] = [0 -3 2; -3 0 -1; 2 -1 0]

Now, X = A-1 B = [0 -3 2; -3 0 -1; 2 -1 0] [11; 21; 27] = [-4; 5; 2]

Therefore, the solution of the given system of equations is x = -4, y = 5 and z = 2.
