Given that m < 1 = 5x, and m <2 = 9x, and that they are complementary angles with a sum of 90°:

We can establish the following formula:

m < 1 + m < 2 = 90°

Substitute the given values into the formula:

5x + 9x = 90°
Add like terms:

14x = 90°

Divide both sides by 14:
14x / 14 = 90° / 14

x = 6.42857

Substitute the value of x into m < 1:

m < 1 = 5x = 5(6.42857)
m < 1 = 32.1°

To verify whether we have the correct value for x, let’s substitute its value into the original equation:

m < 1 + m < 2 = 90°
5x + 9x = 90°
32.1 + 9(6.42857) = 90°
32.1 + 57.9 = 90°
90° = 90° (True statement. Therefore, we derived the correct value for x).

Therefore, the correct answer is: m < 1 = 32.1°

Step-by-step explanation:

We know,

Angle 1 and Angle 2 are complementary.

That is they have a measure of 90°.

And the question says

Angle 1 = 5x

Angle 2 = 9x

So ,

<h3>According to the question</h3>

5x + 9x = 90

=  > 14x = 90

=  > x =  \frac{90}{14}

=  > x = 6.4(rounding \: to \: the \: nearest \: tenths \: )

So,

As Angle 1 = 5x and the value of x is 6.4

The measure of angle 1 will be

5x

=  > 5(6.4)

=  > 32

So the measure will be 32° ( rounding to the nearest tenths )

Hope it helps you!!

Evaluate the expression. simplify your answer. 2/3 x 1/4 / 4/5
Arturiano [62]

Answer:

The answer is 5/24.

Step-by-step explanation:

2/3 multiplied by 1/4 is 2/12 which simplifies to 1/6. CCF (copy, change, flip) is applied to 4/5 and modifies the equation to become 1/6*5/4 for a final answer of 5/24.

What are the dimensions of the matrix?
DerKrebs [107]

Answer:

  • The dimensions of a matrix are the number of rows × the number of columns of the matrix.
  • For the example below, the the matrix is 3 × 4.

Explanation:

<em>The dimensions of a matrix</em> is the number of rows × the number of columns of the matrix.

Your matrix is garbled. Thus, to help you I will work with an hypothetical matrix.

Assume the matrix:

        \left[\begin{array}{cccc}1&0&0&0\\2&4&0&3\\0&0&0&9\end{array}\right]

That matrix has four colums and 3 rows.

For instance, the first colum is:

            \left[\begin{array}{c}1\\2\\0\end{array}\right]        Thus, it has 4 columns.

And the second row is:

          \left[\begin{array}{cccc}2&4&0&3\end{array}\right]         Thus, it has 3 rows.

Hence,  the matrix is 3 × 4.

The first number is the number of rows and the second number is the number of columnns.

Stels [109]

Answer: 90% confidence interval is; ( - 0.0516, 0.3752 )

 

Step-by-step explanation:

Given the data in the question;  

n1 = 72, n2 = 17

P1 = 54 / 72 = 0.75

P2 = 10 / 17 = 0.5882

so

P_good = 0.75

P_bad = 0.5882

standard ERRROR will be;

SE = √[(0.75×(1-0.75)/72) + (0.5882×(1-0.5882)/17)]

SE = √( 0.002604 + 0.01424)

SE = 0.12978

given confidence interval = 90%

significance level a = (1 - 90/100) = 0.1, |Z( 0.1/2=0.05)| = 1.645   { from standard normal table}

so

93% CI is;

(0.75 - 0.5882) - 1.645×0.12978 <P_good - P_bad<  (0.75 - 0.5882) + 1.645×0.12978

⇒0.1618 - 0.2134 <P_good - P_bad<  0.1618 + 0.2134

⇒ - 0.0516  <P_good - P_bad< 0.3752

Therefore 90% confidence interval is; ( - 0.0516, 0.3752 )
