The value of the missing angle x will be equal to 31°.

<h3>What is the supplementary angle?</h3>

Supplementary angles are those that total 180 degrees. Angles 130° and 50°, for example, are supplementary angles because the sum of 130° and 50° equals 180°.

The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.

Given that the two angles of the triangle are 111 and 38. The value of the missing angle will be calculated as,

x + 111 + 38 = 180

x = 180 - 111 - 38

x = 31

Therefore, the value of the missing angle x will be equal to 31°.

TEA [102]

Answer:

The correct answer will be "0.3043".

Step-by-step explanation:

The given values are:

$\mu = 15$

$n=41$

$\sigma^2=25$

then,

$\sigma=5$

If researchers know representative sample n > 30 and default deviation those who use z-test

∴ $P(x>15.4)$

⇒ $1-P(x$

⇒ $1-P(\frac{x-\mu}{\frac{\sigma}{\sqrt{n} } }$

⇒ $1-P(Z$

⇒ $1-0.695762$

⇒ $0.3043$

There is a 96% customer retention rate for the third quarter.

Given

Jenny owns a salon.

She had 150 customers at the end of the third quarter, 151 customers at the beginning of the third quarter, and five new customers in the third quarter.

<h3>Customer retention rate;</h3>

It determines the percentage of customers that the company has retained over a given period.

The customer retention rate is determined by;

$\rm Customer\ retention\ rate=\dfrac{Given \ period - New \ customers}{Initial \ number}\times 100$

Substitute all the values in the formula;

$\rm Customer\ retention\ rate=\dfrac{Given \ period - New \ customers}{Initial \ number}\times 100\\\\\rm Customer\ retention\ rate=\dfrac{150-5}{151}\times 100\\\\\rm Customer\ retention\ rate=\dfrac{145}{151}\times 100\\\\\rm Customer\ retention\ rate=0.96 times 100\\\\\rm Customer\ retention\ rate=96 \ percent$

Hence, there is a 96% customer retention rate for the third quarter.
