Answer:

The angle bisector is construct.

Step-by-step explanation:

We used the geogebra.org site. We first constructed a large triangle with acute angles. Then from point A we made a semicircular section to its sides. At the intersection of the sides and the semicircular section, we construct two circles so that they intersect. Then from the point A we draw a line through the intersection of the circles and thus we obtain the bisector of the angle.

We repeat the same procedure for point B and for point C. In this way, we obtain a bisector for all angles of a triangle.

Answer:

D

Step-by-step explanation:

A)

3(2) + 4(-2) = -2 2(2)-4(-2) = -8

6 - 8 = -2 4 + 8 = -8

Correct Incorrect

B)

3(6) + 4(-5) = -2 2(6) - 4(-5) = -8

18 - 20 = -2 12 + 20 = -8

Correct incorrect

C)

3(4) + 4(4) = -2

12 + 8 = -2

incorrect

D)

3(-2) + 4(1) =-2 2(-2) - 4(1) = -8

-6 + 4 = -2 -4 - 4 = -8

Correct Correct

(a) Find a 90% confidence interval for the population mean price (per 100 pounds) that farmers in this region get for their wate

Anon25 [30]

Answer:

The margin of error (E) $=0.49$

Step-by-step explanation:

Given,

mean $\bar{x}=6.88$

standard deviation $\sigma=1.90$

sample size $n=41$

$90\% \quad \text{confidence interval}$

Critical value $=\frac{z_\alpha}{2}\quad \quad\quad[\because\;\alpha=1-\text{confidence interval}]$

$=1-0.90$

$\Rightarrow \alpha=0.1$

Critical value $=\frac{z_{0.1}}{2}$

$=z_{0.05}$

$=1.645$

The margin of error (E) $=\frac{z_\alpha}{2} \times\frac{\sigma}{\sqrt{n} }$

$=1.645\times\frac{1.90}{\sqrt{41} }$

$=0.49$

Hence, The margin of error (E) $=0.49$
