The number of triangles is (a) 1 triangle

From the question, we have the following parameters that can be used in our computation:

m/A = 51°, a = 22,b = 27

There is only one triangle that can be created using the given parameters

This is so because the given information provides the angle measure of one angle of the triangle and the lengths of the two sides adjacent to that angle.

These three pieces of information (angle measure and two side lengths) are enough to determine the unique triangle.

The total problems assigned over the weekend are 15.

In mathematics, a fraction is used to denote a portion or component of the total. It stands for the proportionate pieces of the whole. Numerator and denominator are the two components that make up a fraction. The numerator is the number at the top, while the denominator is the number at the bottom. The denominator specifies the total number of equal parts in the whole, whereas the numerator specifies the number of equal parts that were taken.

Let us suppose the total number of problems assigned = x.

Given that the problems solved on Saturday is 3/5 of her total questions. This is represented as:

(3/5) x

The remaining problems are:

1 - (3/5) x = (2/5) x

On, Sunday the problems solved are 1/3 of the remaining. This is represented as:

(1/3) (2/5) x

(2/15) x

The remaining problems are:

(1 - 1/3)(2/5 x) = (2/3) * (2/5) x = 4/15 x

Given that the final number of problems remaining are 4, that is:

(4/15) x = 4

x = 4 (15/4)

x = 15

Hence, the total problems assigned over the weekend are 15.

Step-by-step explanation:

The angles that share the same sine value as sin(45°) have terminal sides in second quadrant .

The sine function relates the ratio of the length of the side opposite an acute angle to the length of the hypotenuse of a right triangle. The sine of an angle is always between -1 and 1.

The sine of 45 degrees is √2/2, which is a positive value. Since the sine of an angle is positive in the first and second quadrants, the angles that share the same sine value as sin(45°) must have their terminal sides in the first or second quadrant.

To find the angles that have the same sine value as 45 degrees, we can use the inverse sine function, also known as the arcsine function. The arcsine of √2/2 is 45 degrees or π/4 radians, which is an angle in the first quadrant.

However, since the sine function is periodic, there are infinitely many angles with the same sine value as 45 degrees, and they are all separated by integer multiples of 360 degrees or 2π radians.

Therefore, the angles that share the same sine value as sin(45°) have terminal sides in second quadrant, and can be represented by the formula:

θ = n(360°) ± 45°

or

θ = n(2π) ± π/4

where n is an integer.

Step-by-step explanation:

The ordered, rooted tree representing the infix form of the equation (20 pts.)((X*Y) + (Y * ((X+5) * (Y+7))))/3 is illustrated below. The prefix form of the equation is (/ (+ (* (pts. 20) (* X Y)) (* Y (* (+ X 5) (+ Y 7)))) 3).

To create the ordered, rooted tree for the infix form of the equation, we start by breaking down the equation into its individual components and operators. The tree is built by considering the hierarchy of operations and associativity rules.

The infix equation can be divided into different levels based on parentheses and operators. The tree structure represents the hierarchical relationship between these levels. Here is the tree representation of the infix equation:

                            /

                          /   \

                         +     3

                        / \

                      *     *

                     / \   / \

                pts. 20  *   *

                           / \ / \

                          X  Y +

                               / \

                              X  5

                                 / \

                                Y   7

To obtain the prefix form of the equation, we traverse the tree in a prefix (pre-order) manner. Starting from the root node, we visit the current node, followed by its left subtree, and then its right subtree. This gives us the following prefix form:

(/ (+ (* (pts. 20) (* X Y)) (* Y (* (+ X 5) (+ Y 7)))) 3)

In the prefix notation, the operators appear before their operands, which allows for easy parsing and evaluation of the expression.

Therefore, the prefix form of the given equation is (/ (+ (* (pts. 20) (* X Y)) (* Y (* (+ X 5) (+ Y 7)))) 3).

Answer:

they take 5 dollars and 40 cents off of it so it would be $48.60

a) The range of the given data set is 25.

b) The standard deviation of the given data set is 10.1.

The given data set is 141, 116, 117, 135, 126, 121.

a) The range is the difference between the highest and lowest values within a set of numbers.

Range = Highest value - Lowest value

= 141-116

= 25

So, the range is 25.

b) Set up the formula for sample standard deviation. The standard deviation of a set of values is a measure of the spread of its values.

\(s=\sqrt{\frac{(x_i-\bar x)^2}{n-1} }\)

Here, mean (\(\bar x\)) = \(\frac{141+116+117+135+126+121}{6}\)

= 126

\(s=\sqrt{\frac{(141-126)^2+(116-126)^2+(117-126)^2+(135-126)^2+(126-126)^2+(121-126)^2}{6-1}}\)

\(s=\sqrt{\frac{(15^2+(-10)^2+(-9)^2+(9)^2+(0)^2+(-5)^2}{5}}\)

\(s=\sqrt{\frac{(225+100+81+81+25)}{5}}\)

\(s=\sqrt{\frac{512}{5}}\)

s=10.1

So, the standard deviation is 10.1.

Therefore,

a) The range of the given data set is 25.

b) The standard deviation of the given data set is 10.1.

Answer:

Si puede asegurarse, ya que la inversión en la cuenta bancaria que da un 8% anual, es menor a 100 000 y mayor que 500 000.

Step-by-step explanation:

Ci= 100 000 $

Cuenta #1 = 8% de interés simple. con depósitos de 50 000$.

La segunda para 6.4% con interés simple para depósitos de 100 000$

Determine si el dinero se puede depositar para que fenere un interés de 7500

7500 = C1(0.08)+C2(0.064)

C1+C2= 100 000

C2 = 100 000 -C1

7500 = C1(0.08)+(100 000 - C1)(0.064)

1100= 0.016 C1

C1= 68750$.

The equation 2 = -x√(x + 2) - x has two potential solutions: x = -1 and x = -8. However, x = -8 does not satisfy the equation, so the set of all solutions is {x = -1}.

To find the set of solutions to the equation 2 = -x√(x + 2) - x, we can solve it algebraically.

Starting with the given equation, we can simplify it step by step:

2 = -x√(x + 2) - x

Adding x to both sides:

2 + x = -x√(x + 2)

Squaring both sides to eliminate the square root:

(2 + x)^2 = (-x√(x + 2))^2

Expanding and simplifying:

4 + 4x + x^2 = x^2(x + 2)

Simplifying further:

4 + 4x = x^3 + 2x^2

Rearranging terms:

x^3 + 2x^2 - 4x - 4 = 0

Factoring the equation:

(x + 1)(x^2 + x - 4) = 0

Setting each factor to zero:

x + 1 = 0 or x^2 + x - 4 = 0

Solving the first equation, we find x = -1.

For the second equation, we can use the quadratic formula:

x = (-1 ± √(1^2 - 4(1)(-4))) / (2(1))

x = (-1 ± √(1 + 16)) / 2

x = (-1 ± √17) / 2

However, when we substitute x = (-1 + √17) / 2 into the original equation, it does not satisfy the equation. Therefore, x = -8 is not a solution.

Hence, the set of all solutions to the equation is {x = -1}.

Based on the given sample, the number of voters vote for the incumbent are 1,200,000.

Based on the sample, it can be estimated that approximately 1,200,000 of the 2,000,000 voters will vote for the incumbent.

This can be calculated by taking the sample size of 10 and multiplying it by the proportion of votes that the incumbent received (6/10).

This gives a result of 6/10 x 2,000,000 = 1,200,000.

However, it is important to note that this is just an estimate and the actual number of votes for the incumbent could be higher or lower than 1,200,000.

Therefore, based on the given sample, the number of voters vote for the incumbent are 1,200,000.
