the survey results for a group of students who were asked how many honors classes they have taken and how many elective classes: A scatter plot is shown with the title class choices. The x-axis is labeled a number of honors classes and the y-axis is labeled a number of electives. Data points are located at 1 and 8, 3 and 6, 3 and 9, 5 and 3, 6 and 6, 6 and 9, 8 and 6. A line of best fit crosses the y-axis at 9 and passes through the point 6 and 6. How many elective classes would a student likely have taken if he or she has taken 12 honors classes? (4 points)

Answer:

3 electives

Step-by-step explanation:

two points on line of best fit are: (6,6) and (0,9)

gradietn of line= (9-6)/(0-6)=-1/2

y-intercept=9

so equation of line of best fit is,

y= -x/2+9

For number of honors classes equal to 12 that is x=12,

y= -12/2 + 9

y=3

Number of electives =3

1.) Y= one half x + one
2.) 3 because Y= negative one half x +9

What is the answer for # 24?<br><br>A B C or D
Rainbow [258]

The volume of the space not filled by the sphere is the difference between the volume of a cube with edge length 6 inches and the volume of a sphere with radius 3 inches.

<h3><u>Cube</u></h3>

The volume of a cube of edge length s is

... V = s³

When the edge length is 6 in, the volume is

... V = (6 in)³ = 216 in³

<h3><u>Sphere</u></h3>

The volume of a sphere with radius r is

... V = (4/3)π·r³

When the radius is 3 in, the volume is

... V = (4/3)π·(3 in)³ = 36π in³

<h3><u>Space</u></h3>

Then the volume of the space between the cube and the sphere is

... Vcube - Vsphere = 216 in³ - 36π in³ ≈ 102.9 in³ . . . . corresponding to choice C

marusya05 [52]

A plane has fees for 420 passengers 15% of the seats are empty how many passengers are on the plane​
serious [3.7K]

Answer:

357 passengers

Step-by-step explanation:

\frac{x}{420}=\frac{85}{100} (The \frac{85}{100} is 85% of the 100% people because 15% is missing)

When you cross-simplify you get: \frac{x}{21}=\frac{85}{5} which is \frac{x}{21}=17

Finally, multiply 17 by 21 to get x.

Therefore, x=357
