determina la medida de cada uno de los angulos del triángulo ABC si se conoce que (3x+1)° (3x+4)° y (2x-1)°​
Triss [41]

Answer:

∠A=67°

∠B=70°

∠C=43°

Step-by-step explanation:

<u><em>The correct question in English is</em></u>

Determines the measurement of each of the angles of the triangle ABC if it is known that A=(3x+1)°,B=(3x+4)° and C=(2x-1)°.

we know that

The measure of the interior angles in a triangle must be equal to 180 degrees

so

∠A+∠B+∠C=180°

substitute the given values

(3x+1)\°+(3x+4)\°+(2x-1)\°=180\°

solve for x

(8x+4)\°=180\°

8x=180-4

x=22

Find the measure of each angle

∠A=(3(22)+1)=67°

∠B=(3(22)+4)=70°

∠C=(2(22)-1)=43°

Suppose that 950 couples each have a baby find the mean and standard deviation for the number of boys in the 950 babies
nydimaria [60]

The mean and standard deviation for the number of boys in the 950 babies are 475 and 15.41, respectively

<h3>How to determine the mean and the standard deviation?</h3>

From the complete question, we have:

P(boy)= 0.5

Sample size = 950

The mean is then calculated as:

\bar x = np

This gives

\bar x = 950 * 0.5

Evaluate

\bar x = 475

The standard deviation is calculated as:

\sigma = \sqrt{np(1 - p)

This gives

\sigma = \sqrt{950 * 0.5(1 - 0.5)

Evaluate

\sigma = 15.41

Hence, the mean and standard deviation for the number of boys in the 950 babies are 475 and 15.41, respectively
