lilavasa [31]

Answer:

575.8 cubic cm

Step-by-step explanation:

V(cone) = 1/3· π · r² · h

V = 1/3 · π · 25 · 12

V = 4(25)π or 100π = 314

V(half-sphere) = (4/3 · π r³)/2

V = (4/3π · 125) = 261.8

The statement third, “This is voluntary response bias. The result overestimates true support for firing the coach” is correct.

<h3>What is a survey?</h3>

A survey is a means of gathering information from a sample of people using pertinent questions with the goal of understanding populations as a whole.

We have:

A local baseball team is struggling this season, and many fans of the team believe it may be time to replace the head coach.

Number of votes V(n) = 2367

After the value of V(n) 79% of those who responded felt the coach should be fired.

Based on the data given, we can say this is referred to as voluntary response bias. The outcome exaggerates the level of support for firing the coach.

Thus, the statement third “This is voluntary response bias. The result overestimates true support for firing the coach” is correct.

Explain weather or not the two triangles below could lie on the same line. Be sure to use the slope of each triangle in your jus
KonstantinChe [14]

Answer:

No, these triangles cannot lie on the same line.

Step-by-step explanation:

For two triangles to lie on the same line they must have the same slope.

The slope of the bigger triangle is

m=\frac{rise}{run} =-\frac{18}{10} =-1.8

and the slope of the smaller triangle is

m=\frac{rise}{run} =-\frac{2}{3} =-0.67

slopes are negative because the triangles are leaning to the left.

We see that the slopes of the two triangles are not the same; therefore, they cannot lie on the same line.
