What is the value of x?

Mathematics
1 answer:
givi [52]3 years ago
5 0

Answer:

x = 12

Step-by-step explanation:

The 2 given angles form a straight angle and are supplementary, thus

10x - 20 + 6x + 8 = 180

16x - 12 = 180 ( add 12 to both sides )

16x = 192 ( divide both sides by 16 )

x = 12

Assume that the average healthy body temperature is 98.249 degrees and the standard deviation is 0.733 degrees. How many standar
Leno4ka [110]

The standard deviation is 1.43 below the mean

<h3>How to determine the number of standard deviation?</h3>

The given parameters are:

Mean = 98.249

Standard deviation = 0.733

x = 97.2

To calculate the number of standard deviation below the mean, we use

x = \bar x - n\sigma

So, we have:

97.2 = 98.249 - n * 0.7333

Evaluate the like terms

-1.049  =- n * 0.7333

Divide both sides by -0.733

n =1.43

Hence, the standard deviation is 1.43 below the mean

9. Find the length of TR if TL = 24 and TR:RV:VL is 3:4:5
Sladkaya [172]

Answer:

length TR = 6

Step-by-step explanation:

Length TL = 24

scale ratio = 3:4:5

T-------R--------V----------L

find: TR

24 / (3+4+5) = 2

length TR at 3 x 2 = 6  

length RV at 4 x 2 = 8

length VL at 5 x 2 = 10

a total of 6 + 8 + 10 = 24

therefore,

length TR = 6
