a.) b = -71
b.) b = -80
c.) b = -83
d.) b = -74

Answer:

60°

Step-by-step explanation:

The sum of the angles in any quadrilateral is 360°. In a parallelogram the sum of neighboring angles is 180°. Therefore:

2x + x = 180°

3x = 180°

x = 60°

The  value of x is 60.

Given:

Angles x, x, 2x, 2x.

Using the property of parallelogram, the adjacent angles of parallelogram sum to 180.

x+ 2x= 180

3x= 180

x= 180/3

x= 60

Hence, the value of x is 60.

It's incorrect. There are 6 moles of NaBr produced for every 3 moles of Na₂S among the reactants (as well as 2 moles of FeBr₃), so the mole ratio of NaBr to Na₂S should be 2 : 1, not 1 : 1.

Answer:

After solving we get [tex]\mathbf{i^3=-i}[/tex]

Option D is correct.

Step-by-step explanation:

We are given:

If  [tex]i=\sqrt{-1}[/tex] we need to find the value of [tex]i^3[/tex]

Solving:

[tex]i=\sqrt{-1}[/tex]

Taking cube on both sides

[tex]i^3=(\sqrt{-1})^3\\[/tex]

We can write [tex]a^3= a^2.a^1[/tex] Using this for solving:

[tex]i^3=(\sqrt{-1})^2.(\sqrt{-1})\\We \ know \ (\sqrt{-1})^2 =- 1 \ and \ \sqrt{-1}=1 \\i^3=-1(i)\\i^3=-i[/tex]

So, after solving we get [tex]\mathbf{i^3=-i}[/tex]

Option D is correct.

Answer:

we can not reject any value

Step-by-step explanation: From data we can test the highest and the lowest value to evaluate if one of these values are out of certain confidence Interval

If we established CI = 95 % then  α = 5 % and  α/2 = 0,025

From data we find the mean of the values

μ₀  = 12,03   and σ = 0,07

From z table we find z score for 0,025 is  z(c) = ± 1,96

So limits of our CI are:

12,03 + 1,96 =  13,99

12,03 - 1,96 = 10,07

And all our values are within  ( 10,07 , 13,99)

So we can not reject any value

A subtraction expression to determine the original value of Amy's paycheck is x-10=65.

Given that, Amy had a $10 monthly fee for music streaming due when she received her paycheck.

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

Let the original value of Amy's paycheck be x

According to the question, x-10=65

⇒ x=$75

Therefore, a subtraction expression to determine the original value of Amy's paycheck is x-10=65.

The point-slope equation for a line is:

[tex]y-\left(-1\right)=\frac{1}{5}\left(x-5\right)[/tex]

Step-by-step explanation:

Given

We know that the point-slope form is

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line

substituting the values m = 1/5 and the point (5, -1)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-\left(-1\right)=\frac{1}{5}\left(x-5\right)[/tex]

Thus, the point-slope equation for a line is:

[tex]y-\left(-1\right)=\frac{1}{5}\left(x-5\right)[/tex]
