Find m∠MON<br> I have a hard time with theses
fredd [130]

Answer:

m∠MON = 15°

Step-by-step explanation:

The given parameters are;

m∠LON = 77°

m∠LOM = 9·x + 44°

m∠MON = 6·x + 3°

By angle addition postulate, we have;

m∠LON = m∠LOM + m∠MON

Therefore, by substituting the known values, we have;

∴ 77° = 9·x + 44° + 6·x + 3°

77° = 9·x + 44° + 6·x + 3° = 15·x + 47°

77° = 15·x + 47°

77° - 47° = 15·x

15·x = 77° - 47° = 30°

15·x = 30°

x = 30°/15 = 2°

x = 2°

Given that m∠MON = 6·x + 3° and x = 2°, we have;

m∠MON = 6 × 2° + 3° = 12° + 3° = 15°

m∠MON = 15°.

Dullco Manufacturing claims that its alkaline batteries last at least 40 hours on average in a certain type of portable CD playe
algol13

Answer:

The value is  p- value  = 0.041815

Step-by-step explanation:

From the question we are told that

  The  population mean is \mu  =  40 \ hours

  The  sample size is  n  =  18

    The  sample mean is  \= x =  37.8 \ hours

   The standard deviation is  \sigma  = 5.4\ hours

The null hypothesis is  H_o  :  \mu =  \ge 40

The alternative hypothesis is  H_a  :  \mu < 40 \ hour s

Generally the test statistic is mathematically evaluated as

       t=  \frac{\= x - \mu}{ \frac{\sigma}{ \sqrt{n} } }

      t=  \frac{37.8 - 40}{ \frac{5.4}{ \sqrt{18 } }

      t=  -1.73

From the z - table the p-value is obtained and the value is  

      p- value  =  P(Z <  -1.73)

        p- value  = 0.041815

12494a-194879=1928777

          +194879= +194879

         12494a  =    2123656

       ÷ 12494     =  ÷     12494

                     a  =  169.974068
