Answer:

x =12

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles

30 + 4x+2 = 8+6x

Combine like terms

32 +4x = 8+6x

Subtract 4x from each side

32+4x-4x = 8+6x-4x

32 = 8+2x

subtract 8 from each side

32-8 = 8-8+2x

24 = 2x

Divide each side by 2

24/2 =2x/2

12 =x

SIZIF [17.4K]

Answer: 0.8137

Step-by-step explanation:

As per given , we have

$\mu= 17.2\ ,\ \sigma=2.5$

Sample size : n= 47

Let $\overline{X}$ be the sample mean o.

Then, the probability that the mean of a sample of 47 families will be between 16.6 and 17.6 pounds will be :

$P(16.6$

$=P(-1.645$

[∵ $z= \dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}$ ]

$=P(z$

$=0.8636793-(1- 0.9500151)$ [By using p-value calculator]

$=0.8636793-0.0499849=0.8136944\approx0.8137$

Hence, the probability that the mean of a sample of 47 families will be between 16.6 and 17.6 pounds= 0.8137
