Answer:

361/900

Step-by-step explanation:

First, multiply 0.6 by (-1/3) to get -0.2 which equals (-1/5).

Now the equation is \((-\frac{1}{6}-0.2+1 )^{2}\)

Next, solve the inside of the parenthesis \(-\frac{1}{6}-\frac{1}{5} +1 = \frac{19}{30}\)

Now the equation is \((\frac{19}{30})^{2}\)

Finally we square this to get the simplified fraction of \(\frac{361}{900}\)

The expression that is equivalent to \(80^{(1/4}\) * x is \(80^{4/x}\)

To determine the equivalent expression to \(80^{1/4}\) * x, let's analyze each option:

\(80/4^{x}\)

This expression simplifies to \(20^{x}\), but it is not equivalent to the original expression.

Applying the power of a power rule, this expression simplifies to \(80^{x/4}\) , which is not equivalent to the original expression.

\(80/x^{4}\)

This expression can be simplified as \(80^{4 x^{4} }\) , which is not equivalent to the original expression.

Therefore, the expression that is option d.

Answer:

11:1

Step-by-step explanation:

For every 11 copies, 1 minute passes. Four minutes passed in this case and thus 11*4 would equal 44 and 1*4 would equal 4.

Step-by-step explanation:

Let x be the amount of tickets sold for $25 and y be the amount of tickets sold for $40, since there are 6000 seats theatre then;

x+y = 6000 .............. 1

If x tickets cost $25 and y tickets are sold for $40 with total revenue of ​$174,000, then;

25x + 40y = ​174,000................ 2

From 1, x = 6000-y ............ 3

Substitute equation 3 into 2:

25x + 40y = ​174,000.

25(6000-y) + 40y = ​174,000

150,000-25y + 40y = 174,000

150,000+15y = 174,000

15y = 174,000-150,000

15y = 24,000

y = 24,000/15

y = 1600

Substitute y = 1600 into equation 3:

x = 6000-y

x = 6000-1600

x = 4400

Hence 4400 $25 tickets and 1600 $40 tickets must be sold to generate a revenue of $174,000

The 95% confidence interval estimate for the mean number of absences for clerical workers during the year is (8.132, 11.268).

It should be noted that the mean of your estimate plus and minus the range of that estimate constitutes a confidence interval. Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within if you repeat the test. In statistics, confidence is another word for probability.

Given a = 0.05, Z(0.025) = 1.96 (from standard normal table).

The 95% confidence interval will be:

xbar +/- Z*s/vn

= 9.7 +/- 1.96*4/✓(25)

= (8.132, 11.268)

Therefore, the 95% confidence interval is (8.132, 11.268).

The solutions of the system of equations are (-2, 1) and (-4, 5). The answer is D) (-4,5) and (-2,1).

What is equation ?

In mathematics, an equation is a statement that two expressions are equal. It typically contains one or more variables, which are unknowns that can take on different values. An equation is written using an equal sign (=) to indicate that the expressions on either side have the same value.

To solve the system of equations y = -\((x+2) ^{2}\) + 1 and y = 2x + 5, we can set the two expressions for y equal to each other and solve for x:

-\((x+2) ^{2}\) + 1 = 2x + 5

Expanding the left side and simplifying, we get:

-x*x - 4x - 4 + 1 = 2x + 5

-x*x - 6x - 8 = 0

Dividing both sides by -1, we get:

x*x+ 6x + 8 = 0

Factoring the left side, we get:

(x+2)(x+4) = 0

So the solutions for x are x = -2 and x = -4.

To find the corresponding y-values for each solution, we can plug in each value of x into either equation and solve for y. Let's use the equation y = -\((x+2) ^{2}\)+ 1:

When x = -2, y = -\((x+2) ^{2}\) + 1 = -(0) + 1 = 1.

When x = -4, y =-\((x+2) ^{2}\)+ 1 = -(-4) + 1 = 5.

Therefore, the solutions of the system of equations are (-2, 1) and (-4, 5).

Answer:

Step-by-step explanation:

Shannon is designing a rectangular flag.

Therefore, all the interior angles of this flag measure 90°.

m∠1 + m∠2 = 90°

Since, ∠2 is 3 times as great as the measure of ∠1.

m∠2 = 3(m∠1)

Therefore, m∠1 + 3(m∠1) = 90°

4(m∠1) = 90°

m∠1 = 22.5°

m∠2 = 3(m∠1)

        = 3(22.5)°

        = 67.5°

m∠3 + m∠4 = 90° [Interior angle of a rectangle]

She thinks ∠3 and ∠4 are equal,

m∠3 = m∠4

m∠3 + m∠3 = 90°

2m∠3 = 90°

m∠3 = 45°

m∠4 = m∠3 = 45°

m∠2 = m∠6 [Opposite angles of a parallelogram are equal]

Therefore, m∠2 = m∠6 = 67.5°  

Finally she wants the measure of ∠6 is half of the measure of ∠5.

m∠6 = \(\frac{1}{2}\)(m∠5)

67.5° = \(\frac{1}{2}\)(m∠5)

m∠5 = 2(67.5)°

        = 135°

Answer: Shannon is designing a rectangular flag.

Therefore, all the interior angles of this flag measure 90°.

m∠1 + m∠2 = 90°

Since, ∠2 is 3 times as great as the measure of ∠1.

Therefore, m∠1 + 3(m∠1) = 90°

4(m∠1) = 90°

m∠1 = 22.5°

m∠2 = 3(m∠1)

       = 3(22.5)°

       = 67.5°

m∠3 + m∠4 = 90° [Interior angle of a rectangle]

She thinks ∠3 and ∠4 are equal,

m∠3 = m∠4

m∠3 + m∠3 = 90°

2m∠3 = 90°

m∠3 = 45°

m∠4 = m∠3 = 45°

m∠2 = m∠6 [Opposite angles of a parallelogram are equal]

Therefore, m∠2 = m∠6 = 67.5°  

Finally she wants the measure of ∠6 is half of the measure of ∠5.

m∠6 = (m∠5)

67.5° = (m∠5)

m∠5 = 2(67.5)°
