Answer:

Step-by-step explanation:

Standardizing a normal distribution is to convert a normal distribution to the standard normal distribution.

The equation x2 − xy + y2 = 3 represents a "rotated ellipse," that is, an ellipse whose axes are not parallel to the coordinate
Setler [38]

Answer:

the points where the ellipse crosses the x- axis are (1.73, 0) and (-1.73, 0)

Step-by-step explanation:

To find the points at which a graphic crosses the x-axis we need to find the values for x where y = 0.

Therefore, in the equation x²- xy + y² = 3 we are going to make y = 0 and solve for x

x² - xy + y² = 3

x²- x(0) + (0)² = 3

x² = 3

x = ±√3

x₁ = 1.73 and x₂ = -1.73

Therefore, the points where the ellipse crosses the x- axis are (1.73, 0) and (-1.73, 0)

There are 42 students on a large bus and the rest are on a smaller bus. If 40% of the students are on the smaller bus how many t
Liono4ka [1.6K]

Answer:

<u>There are 70 students on the two buses, 42 on the large and 28 on the smaller.</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Number of students on the large bus = 42

Number of students on the small bus = 40% of the students

2. How many total students are on the two buses?

For answering the question, we will use the Rule of Three Simple, this way:

42 students are 60% of total students, how much students are the 100%?

Total students = 42 * 100/60

Total students = 4,200/60 = 70

<u>There are 70 students on the two buses, 42 on the large and 28 on the smaller.</u>

2p+6a=$14
3p+9a=$21

3p+9a=21
Subtract 9a
3p=21-9a
divide all by 3
p=7-3a
plug it into start equations

2p+6a=14
2(7-3a)+6a=14
14-6a....+6a=14

this zeroes out...
