Jayne's GPA is 3.6.

To solve, add the number of grade points for each letter grade and divide by the total number of letter grades.

AP English ⇒ 4 points
AP Government ⇒ 6 points
Algebra II ⇒ 3 points
Spanish ⇒ 1 point
Physics ⇒ 4 points
4 + 6 + 3 + 1 + 4 = 18
18 / 5 = 3.6

Write the equation of the sphere in standard form. x2 + y2 + z2 + 8x − 6y + 4z + 20 = 0
Nuetrik [128]

Answer:

(x+4)^2 + (y-3)^2 + (z+2)^2 - 3^2 = 0


Step-by-step explanation:

You have to find a, b, c, r so that the polynomial expands to match the given equation.

(x-a)^2 + (y-b)^2 + (z-c)^2 - r^2 =\\x^2-2ax+a^2+\\y^2-2by+b^2+\\z^2-2cz+c^2-r^2 =\\ x^2 + y^2 + z^2 + 8x - 6y + 4z + 20

(a^2+b^2+c^2-r^2-20)+\\x(-8-2a)+y(6-2b)+z(-4-2c)=0

-8-2a=0, 6-2b=0, -4-2c=0\\a=-4, b=3, c=-2

(-4)^2+3^2+(-2)^2-r^2-20 = 0

16+9+4-20=r^2

r^2=9

r=3

(x+4)^2 + (y-3)^2 + (z+2)^2 - 3^2 = 0

Why do non STEM majors detest taking algebraic courses at the collegiate level?
yKpoI14uk [10]

Answer:

Because they find it hard to pass in the past.

Step-by-step explanation:

Non-STEM majors detest taking algebraic courses at the collegiate level because based on their past experiences in high school, whereby they probably do not excel in algebra, numbers, or mathematical subjects in general, the thought of going through advanced numbers and equations can be overwhelming.

Nobody wants to have or at least start college with poor grades. Hence, because non-STEM students find algebraic courses hard to pass in the past, they detest taking the course that has to do with it at the college level.

What are the zeros of f(x) = x2 - 12x + 36?
topjm [15]

Answer:

c. x = 6 only

Step-by-step explanation:

In order to calculate the zeros of f(x), we need to set it equal to zero and find the corresponding values of x.

x^{2}-12x+36=0

Using the midterm breaking, we can split -12x into two such terms whose sum will be -12x and product will be 36x². These two terms are -6x and -6x

So, the above expression can be written as:

x^2-6x-6x+36=0\\\\ x(x-6)-6(x-6)=0\\\\ (x-6)(x-6)=0\\\\ (x-6)^{2}=0\\\\ x-6=0\\\\ x=6

This means, the zero of f(x) occurs at x = 6 only.

If the null hypothesis of an experiment is “The true mean weight of the geese is greater than 40 pounds” what is the alternate h
Naddika [18.5K]

Answer:

<em>The true average weight of geese is less than or equal to 40 pounds</em>

Step-by-step explanation:

The null hypothesis and the alternative hypothesis are two mutually exclusive statements or hypotheses that are made about a population. The purpose is to find out if, through a study of the data, sufficient evidence is obtained to reject one and accept another

The null hypothesis is denoted as H_0 and the alternative hypothesis as H_1

As they are two mutually exclusive statements then if

H_0: <em>"The true average weight of the geese is greater than 40 pounds"</em>

the alternative hypothesis must be the opposite of the null hypothesis

H_1: <em>"The true average weight of geese is less than or equal to 40 pounds"</em>
