Answer:
2/3
Step-by-step explanation:
If we have 'x' students who like math and 'y' students that like science, we can formulate that:
Half of x likes math and science, and also one third of y likes math and science, so:
(1/2) * x = (1/3) * y
x / y = (1/3) / (1/2)
x / y = (1/3) * 2 = 2/3
So the ratio of the number of students who like math to the number of students who like science is 2/3
Answer:
2/3
Step-by-step Explanation:
1/2 * x = (1/3) * y
x / y = 1/3 / 1/2
x / y = (1/3) * 2 = 2/3
Please help been stuck on this hw question ALLL DAYYYYYY
Answer:
1 5/9
Step-by-step explanation:
9 1/3 can be rewritten as 28/3. The question is asking for you to divide 28/3 by 6. 6 is 6/1, so the expression is 28/3 divided by 6/1. You then do the reciprocal of 6/1 and the expression is [tex]\frac{28}{3} * \frac{1}{6}[/tex]. This gets you 28/18, which is simplified to 14/9 or 1 5/9. Hope this helps!

Given f(x)= 4x^4 find f^-1(x) Then state whether f^-1(x) is a function
Answer:
The inverse is
f^-1(x) = (1/√2)x^¼
And it is a function
Step-by-step explanation:
Given f(x) = 4x^4
Let y = f(x), so that
y = 4x^4
Then dividing both sides by 4
x^4 = y/4
Taking the fourth root of both sides
x = (y/4)^¼
x = (1/√2)y^¼ = f^-1(y)
Put y = x
y = (1/√2)x^¼ = f^-1(x)
This is the inverse.
f^-1(x) is a function.
Evaluate the dot product of (3,-1) and (1,5).
Answer here
Answer:
The dot product is -2
The required dot product of (3,-1) and (1,5) is -2.
Evaluate the dot product of (3,-1) and (1,5).
What is dot product?It is a principle to combine two vectors. It tells about how much two vectors approaching in the same direction.
Now converts the coordinates to vector form.
a = 3i -1j
b = 1i + 5j
Dot product of two vectors a and b,
a.b = 3x1 - 1x5
a.b = 3-5
a.b = 2
Thus, the required dot product of (3,-1) and (1,5) is -2.

A study shows that, over the course of a lifetime, the average salary of college graduates is greater than the average salary of people with only a high school diploma. The results were published claiming that graduating from college ensures you will make more money over the course of your lifetime. What is the problem with reporting results this way?
loaded question
correlation and causality
voluntary response
missing data
Answer:
The problem with reporting this result is:
Missing data.
Step-by-step explanation:
The reason behind this answer is: first of all a loaded question has a bias, the question in our case is arbitrary because it doesn't suggest an inclination of perspective. The correlation between studies and salaries also is not wrong, it is well developed. Therefore, the casualty is well developed. There is no voluntary response because it was not a questionnaire that could have been manipulated. We could have obtained the data from the government database. However, that is what we are lacking. We have no statistics, no source, no institution mentioned, we have missing data.

PLEASE HELP!! Using the SAS Congruence Theorem
Answer:
LAST ONE IS angle JLK congruent to angle LNM, SAS
Step-by-step explanation:
The triangles JLK and LMN are similar by SAS congruence theorem, LJK≅ LNM.
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .
The triangles JLK and LMN are similar triangles.
Which means the sides are proportional and those angles are congruent.
We have to prove that JLK is similar to LMN.
By SAS rule we have "if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar".
So LJK≅ LNM.

The amount of carbon in the trees and in the deer . . .
A) has increased.
B) has decreased.
C) has not changed.
D) is not related to the number of energy storage molecules.
Answer:
a
Step-by-step explanation:
it makes sence for the answer to be a because
Answer:
The amount of carbon in the trees and in the deer . . .
A) has increased.
Explanation:
Carbon is the basis for all living cells, it is responsible for the making and storing of energy. So if the number of energy storage molecules increases, the amount of carbon will increase because carbon is used to make those molecules.
Your question on carbon dioxide and photosynthesis having an effect is valid, but the loss of carbon wouldn't be much compared to the energy storage molecules, so we wouldn't consider that a factor in this case.

ASAP : What is the y-coordinate of the center of the circle for the following circle equation? x2 + y2 - 10y + 18x = 2
Answer:
y = 5
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre ad r is the radius
Given
x² + y² - 10y + 18x = 2 ( Rearrange collecting x and y terms together )
x² + 18x + y² - 10y = 2
Using the method of completing the square
add ( half the coefficient of the x/ y term )² to both sides
x² + 2(9)x + 81 + y² + 2(- 5)y +25 = 2 + 81 + 25
(x + 9)² + (y - 5)² = 108 ← in standard form
with centre = (- 9, 5 )
The y- coordinate of the centre is therefore y = 5
