Can any math genius help me with this

vovangra [49]

Here's my working for 1) You need to find the exterior angle, then divide by 360 to find the number of sides:

Applying these steps : 

180 (Interior Angles) - 162 = 18 (Exterior angle)

360 ÷ 18 is 20 sides 

For 2)

Its the same method, so apply the steps:

180 - 175 = 5

360 ÷ 5 = 72 sides 

Hope it helps! :)

A normal distribution has a mean of 85.3 and a standard deviation of 4.85. Find the data value corresponding to the value of z g

Mazyrski [523]

Answer: 87.9675

Step-by-step explanation:

Formula for z:

$z=\dfrac{x-\mu}{\sigma}$ , where x= data value corresponding to z, $\mu$ = mean, $\sigma$ = standrad deviation.

Given: $\mu$ =85.3, $\sigma$ =4.85, z=0.55

To find : x

$0.55=\dfrac{x-85.3}{4.85}\\\\\Rightarrow\ 0.55\times4.85=x-85.3\\\\\Rightarrow\ 2.6675=x-85.3\\\\\Rightarrow\ x=85.3+2.6675\\\\\Rightarrow\ x=87.9675$

Hence, The required data value= 87.9675
