Answer:

  48°

Step-by-step explanation:

In triangle CYZ, angles Y and C are complementary, so ...

  (5x +22) + (12x) = 90

  17x +22 = 90

  17x = 68

  x = 4

The angle of interest is 12x° , so has measure

  12·4° = 48°

Answer:

The 95% confidence interval   81.852  <  \mu <  280.098

Step-by-step explanation:

From the question we are told that

   The  sample mean is  \= x  =  180.975

   The standard deviation is  \sigma  =  143.042

   The sample size is n = 8

Given that the confidence level is  95%  then the level of significance is  

    \alpha =( 100- 95) \%

=>  \alpha =0.05    

Generally from the normal distribution table the critical value  of  \frac{\alpha }{2} is  

   Z_{\frac{\alpha }{2} } =  1.96

Generally the margin of error is mathematically represented as  

      E = Z_{\frac{\alpha }{2} } *  \frac{\sigma }{\sqrt{n} }

=>  E = 1.96 *  \frac{ 143.042 }{\sqrt{8} }

=>  E = 99.123

Generally 95% confidence interval is mathematically represented as  

      \= x -E <  \mu <  \=x  +E

=>    180.975 -99.123 <  p <  180.975 +99.123

=>    81.852  <  \mu <  280.098

A triangle has side lengths 7 and 4. How long is the third side, c?
jok3333 [9.3K]

Answer:

5,7, or 9

Step-by-step explanation:

a,b and c are the sides of a triangle if it satisfies:

a<b+c  , b<a+c and c<b+a

Here, a=4 and b=7

We have to find c

i.e. all those c which satisfies:

4<7+c , 7<4+c and c<4+7=11
