The measure of two vertical angles are 6x - 22 and 4x + 2. Find x.
maks197457 [2]
Vertical angles are congruent...they are equal....so set them equal to each other and solve for x

6x - 22 = 4x + 2
6x - 4x = 2 + 22
2x = 24
x = 24/2
x = 12 <==

Nina [5.8K]

Answer:

There are 28 dolls, 32 balls,  20 cars   for 80 total toys

Step-by-step explanation:

dolls : balls: cars: total

7           8          5    (7+8+5)

7           8           5        20

We have a total of  80  

80/20 = 4

We need to multiply each number by 4

dolls : balls: cars: total

7*4     8*4     5*4      20*4

28       32      20       80


There are 28 dolls, 32 balls,  20 cars   for 80 total toys

fiasKO [112]

Answer:

The standard deviation of the sample mean is  \sigma _ {\=  x } = 2.711

Step-by-step explanation:

From the question we are told that

   The mean is  \= x  =  60

    The standard deviation is  \sigma  =  21

     The sample size is n  =  60

Generally the standard deviation of the sample mean is mathematically represented as  

               \sigma _ {\=  x } =  \frac{\sigma  }{\sqrt{n} }

substituting values

               \sigma _ {\=  x } =  \frac{ 21 }{\sqrt{60} }

               \sigma _ {\=  x } = 2.711
