Each figure shows a triangle with one of its angle bisectors.

Mathematics

OLga [1]3 years ago

Answer:

m<2 is 17 degrees

Step-by-step explanation:

We can see that the angle at the vertex E was bisected to give two different but equal angles

Thus, we have it that;

2x + 7 = 4x-3

4x-2x = 7+ 3

2x = 10

x = 10/2

x = 5

so m<2 = 4(5) -3 = 20-3 = 17 degrees

Nezavi [6.7K]

According to the hypothesis test, the correct statement of the p-value is mean value is against null hypothesis.

Hypothesis test:

In statistics, hypothesis test means a form of statistical inference that uses data from a sample to draw conclusions about a population parameter or a population probability distribution.

Given,

Here we need to find the correct statement of the p-value for the a hypothesis test for population proportion, you calculated the p-value is 0. 01 for the test statistic.

While we looking into the given question we have identified the value of p value of the test statistic is 0.01.

Then the correct statement of the p-value less than 0.01 will under normal circumstances mean that there is substantial evidence against the null hypothesis.

Bezzdna [24]

Answer:

19 units

Step-by-step explanation:

use distance formula: d = \sqrt{(x_2-x_1)^{2}+(y_2+y_1)^{2}}

x₂ = 10

x₁ = -1

y₂ = 6

y₁ = 6

now plug in

\sqrt{(10-(-9))^{2}+(6-6)^{2}}\\= \sqrt{19^{2}+0^{2}\\}\\= \sqrt{361}\\= 19

A circle has a diameter with endpoints at 15 + 25i and –25 – 17i. Which point is also on the circle? –15 +21i 0 + 0i 15 + 17i 16
Tamiku [17]

Answer:

Option 4 : 16+24i

Step-by-step explanation:

Given a circle has a diameter with end points at(15+25i) and (-25-17i)

Centre would be the mid point of these two points

Centre = (\frac{15-25}{2} ,\frac{25-17}{2} )\\= -5+4i

Out of given four points to find which point lies on the circle

If a point lies on the circle then it would have distance from centre equal to radius.

Radius = distance between two given points/2

=\frac{1}{2} \sqrt{(15+25)^2+(25+17)^2} \\=\frac{58}{2} \\=29

Let us calculate distance form each point.

i)-15+2i:  distance from -5+4i= 10.19

ii) 0+0i : distance from -5+4i = 6.40

iii) 15+17i :  Distance from -5+4i = 23.85

iv) 16+24i: distance from -5+4i= 29

Hence only 4th point lies on the circle
