AleksAgata [21]

Answer:

The right solution is "-8.25".

Step-by-step explanation:

The given values are:

Sampled people,

n = 150

Null and alternative hypotheses will be:

$H_0:p=0.53$

$Ha:p\neq 0.53$

The z-statistics will be:

⇒ $z=\frac{\bar{p}-p_0}{\sqrt{\frac{p_0(1-p_0)}{n} } }$

On substituting the values, we get

⇒ $=\frac{0.2-0.53}{\sqrt{\frac{0.53(1-0.53)}{150} } }$

⇒ $=\frac{-0.33}{\sqrt{\frac{0.24}{150}} }$

⇒ $=\frac{-0.33}{0.04}$

⇒ $=-8.25$

The graph of a linear function intersects with the x axis at a point with an abscissa of 4 and with the y axis at a point with a

Leni [432]

We know that

points are
x intercept
A (4,0)

y intercept
B (0,11)

step 1
find the equation of a line
m=(y2-y1)/(x2-x1)--------> m=(11-0)/(0-4)------> m=-11/4

with m and the point B (0,11)
y-y1=m*(x-x1)
y-11=(-11/4)*(x-0)---------> y=-(11/4)x+11

the answer is
<span>the formula of the function is
</span>y=-(11/4)x+11

Tell which line contains each point for triangle ABC.

gavmur [86]

5. The line that contains the circumcenter in ΔABC is: <em>line k.</em>

6. The line that contains the orthocenter in ΔABC is: <em>line m.</em>

7. The line that contains the centroid in ΔABC is: <em>line l.</em>

8. The line that contains the centroid in ΔABC is: <em>line n.</em>

<h3>What is the Circumcenter of Triangle?</h3>

Circumcenter is the point where all three perpendicular bisectors of the three sides of a triangle meet and they are of equal distance from the three vertices of the triangle.

The line that contains the circumcenter in ΔABC is: <em>line k.</em>

<h3>What is the Orthocenter of a Triangle?</h3>

Orthocenter is the point in a triangle where the three altitudes that are perpendicular to the opposite sides and connect with the vertices of the triangle intersect.

The line that contains the orthocenter in ΔABC is: <em>line m.</em>

<h3>What is the Centroid of a Triangle?</h3>

The centroid of a triangle is a the point of intersection where all three medians of a triangle. Medians of a triangle connects the vertices to the midpoints of the opposite sides of a triangle.

The line that contains the centroid in ΔABC is: <em>line l.</em>

<h3>What is the Incenter of a Triangle?</h3>

The incenter of a triangle is the point in a triangle where all three angle bisectors of the vertices of a triangle.

The line that contains the centroid in ΔABC is: <em>line n.</em>
