Answer:

A=167⁰, B=13⁰

Step-by-step explanation:

A=167⁰

B=13⁰

I HOPE IT HELPED YOU

Answer:

a° = 167°, b° = 13°

Step-by-step explanation:

since the angles in a triangle add to 180°, we can work out b°

90° (right angle) - 77° = 167°

180° - 167° = 13°

since the angle of a straight line is also 180°, a° would be 180° - 13° which is 167°.

The change that will occur to the mean, median, mode of the data matched as follows:

1. e

2. b

3. d

4. a

5. c

To find the mean, the sum of all the values is divided by the number of values.

Given the data, 90, 85, 35, 70, 67, 76, 90, 79, 94, 100, 87, 61, 56, 80, 67, 65, therefore:

1. 35 is an extreme value, so it is an outlier. If we remove 35, the greatest change will be on the mean. (e)

2. If we remove 90, 67 will have the highest frequency. This means the mode of the data will change to 67. (b)

3. If 76 is removed from the data, the median of the data would be 79. (d)

4. If we remove 100, the range of the data would be, 94 - 35 = 59. (a)

5. If we remove 94, the mean of the data = 1108/15 = 73.87

This means the mean of the data will change to 73.87 if we remove 94. (c)

Answer:

  B.  x = 1, y = 0, z = 3

Step-by-step explanation:

Systems of linear equations are readily solved by a suitable calculator or spreadsheet. The attached calculator display shows the solution to be ...

  x = 1, y = 0, z = 3

__

There are several ways a calculator can solve these equations. The method shown here is to input the equations as an augmented matrix of their coefficients, and reduce it to row-echelon form. The right-most column of the reduced matrix is the set of variable values in the same order as the coefficients.

A graphing calculator can also be used to graph the equations. You may have to write one variable in terms of the others. (Here, it is convenient to let z=3-y.) The second attachment shows the solution (x, y) = (1, 0). This is sufficient to choose the correct answer. Or, you can finish the solution by substituting into the expression for z: z = 3 -y = 3 -0 = 3.

Many calculators will solve the system of equations after you enter it as presented in the problem statement.

Answer:

QR ≈ 9.1

Step-by-step explanation:

using the cosine ratio in the right triangle

cos49° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{PR}{QR}[/tex] = [tex]\frac{6}{QR}[/tex] ( multiply both sides by QR )

QR × cos49° = 6 ( divide both sides by cos49° )

QR = [tex]\frac{6}{cos49}[/tex] ≈ 9.1 ( to the nearest tenth )

Answer:

  (d)  240/289

Step-by-step explanation:

The trig identity for the sine of a double angle can be used to find the desired value.

  sin(2θ) = 2sin(θ)cos(θ)

__

The cosine of this 3rd-quadrant angle is negative:

  cos(θ) = -√(1 -(-8/17)²) = -(√(289 -64))/17 = -15/17

Then the desired sine value is ...

  sin(2θ) = 2(-8/17)(-15/17) = 240/289

_____

Additional comment

The attached calculator result comes from the principal value of the arcsine function resulting in a 4th-quadrant angle for negative sine values. Double that angle will still be a 4th-quadrant angle. When the translation is made to the appropriate quadrant, the desired double angle will be a 1st-quadrant angle with a positive sine.

The statement (p and (p => q)) => q) is not a contingency because of it evaluating to only true while a contingency statement includes both true values and some false values.

Contingency is a statement in which there are some true and some false values for every value of its propositional variables.

The statement given is (p and (p => q)) => q), or in more symbolic way, it is: ((p ∧ (p → q)) → q)

Now, let we evaluate it for p = False, and q = False.

Then we get:

(p → q) = T (as False implied False)

Now, (p ∧ (p → q))  is F and T which is F

Then, ((p ∧ (p → q)) → q)  is F  → F which is True, or T.

Thus, p = F,and q = F makes  ((p ∧ (p → q)) → q)  = T

Similarly, the truth table for the statement (p and (p => q)) => q) or simply  ((p ∧ (p → q)) → q) is:

p q ((p ∧ (p → q)) → q)

F F T

F T T

T F T

T T T

Since all the values are true, thus, this isn't a contingency.

Thus, the statement (p and (p => q)) => q) is not a contingency because of it evaluating to only true while a contingency statement includes both true  values and some false values.

Answer:

x + (5x-9)

Step-by-step explanation:

x stands for the number of coins Nancy has

Kevin has 9 less than 5 times what Nancy has, so his part of the expression is 5x-9

To find the total number of coins they have, you have to add Nancy's number of coins x plus Kevin's number of coins 5x-9

x + (5x-9)

But you have to put parentheses around Kevin's 5x-9 so that part of the expression is calculated first, as per order of operations

i just did the question

The correct set notation for the domain of the function is {x | x ∈ R, x ≠ 3}. Option {x | x ∈ R, x ≠ 3} is the correct answer.

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

In this case, the given function is:

F(x) = (x - 4)/(x - 3)

The function is defined for all real numbers (x ∈ R) except when the denominator (x - 3) becomes zero, as division by zero is undefined.

Therefore, we need to find the value of x that makes the denominator zero and exclude that value from the domain.

The denominator becomes zero when:

x - 3 = 0

x = 3

So, the domain of the function is {x | x ∈ R, x ≠ 3}. This set notation means that the function is defined for all real numbers except x = 3. Thus, the correct set notation for the domain of the function is {x | x ∈ R, x ≠ 3}. Option {x | x ∈ R, x ≠ 3} is the correct answer.
