Answer:
x=20
Step-by-step explanation:
bc 25 divided by 10 is 2.5 so you just multiply 8 by 2.5
Answer: X= 20
If solving for x
Step-by-step explanation:
x/25= 8/10
1= reduce the fraction to x/25= 4/5
2= cross multiply 5x=100
3= divide both sides X=20

A bag contains 5 red marbles, 8 blue marbles and 4 green marbles. If three marbles are drawn out of the bag, what is the probability, to the nearest 10th of a percent, that all three marbles drawn will be red?
Without replacement, the probability that all three marbles drawn will be red is 0.01.
What is the probability?Probabiliy is used to determine the likelihood of an event happening. The probability that the event would occur lies between 0 and 1.
Probability of drawing three red marbles = (number of red marbles / total number of marbles) x (number of red marbles / total number of marbles - 1) x (number of red marbles / total number of marbles - 1)
5/17 x 4/16 x 3/15 = 0.01
The probability, to the nearest 10th of a percent, that all three marbles drawn will be red; 1.5%
How to calculate probability?
We are given;
Number of red marbles = 5
Number of blue marbles = 8
Number of Green marbles = 4
Total number of marbles = 5 + 8 + 4
Total number of marbles = 17
Probability of first being red = 5/17
Probability of second being red = 4/16
Probability of third being red = 3/15
Thus;
P(all three marbles drawn are red) = (5/17) * (4/16) * (3/15)
P(all three marbles drawn are red) = 0.0147
Approximating to nearest tenth of a percent = 0.015 = 1.5%

The graph shows a volume of ice cubes versus temperature in degrees celsius. Which of the statements is false?
A. The correlation coefficient is close to zero.
B. Temperature is strongly correlated to the volume of ice cubes.
C. Temperature is the explanatory variable.
D. The data show a negative linear relationship.
The statements which is false about the volume of ice cubes versus temperature graph is the correlation coefficient is close to zero.
What is the correlation coefficient?Correlation coefficient is used to calculate how strong the relationship is between the two variables.
When there is a statistical relationship between two or more variables, then they are said to be in correlation.
Types of correlation-
Positive correlation coefficient- When the value of correlation coefficient is positive, then the value of one variable increases with increase in other variable.Negative correlation coefficient- When the value of correlation coefficient is negative, then the value of one variable decreases with increase in other variable.
The graph shows a volume of ice cubes versus temperature in degrees Celsius.
For a perfect correlation, -1 or +1 values is ideal. Here, some relation can be seen in a negative straight line, which suggest that the correlation coefficient is not close to zero.
Both volume and temperature has strong correlation for linear line where, temperature is the explanatory variable.
Thus, the statements which is false about the volume of ice cubes versus temperature graph is the correlation coefficient is close to zero.

Is the equation y=3x in slope-intercept form? Explain. The equation y=3x in slope-intercept form. Question 2 The slope is and the y-intercept is a .
Given:
The given equation is
[tex]y=3x[/tex]
To find:
Whether the given equation is in the slope intercept form or not, then find the slope and y-intercept.
Solution:
Slope intercept form of a linear function is
[tex]y=mx+b[/tex] ...(i)
Where, m is the slope and b is the y-intercept.
We have,
[tex]y=3x[/tex]
It can be written as
[tex]y=3x+0[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]m=3,b=0[/tex]
Therefore, the given equations is in slope intercept form. The slope of the line is 3 and the y-intercept is 0.

for $1.25 each and 6 doughnuts. The total
cost was $6.90. Write an equation to
determine the cost of a doughnut.
Answer:
x = (1.25 * 3 - 6.90) divided by 6
Step-by-step explanation:
this will get the price of all the milk, then take it out of the total price, then divide it by 6 because there are 6 donuts, this will give you the price of 1 donut

What is the simplest form of 15/60
Answer:
1/4
Step-by-step explanation:
Answer:
15/60 simplified equals:
1/4
Step-by-step explanation:
In the fraction 15/60, 15 is the numerator and 60 is the denominator.
When you ask "What is 15/60 simplified?", we assume you want to know how to simplify the numerator and denominator to their smallest values, while still keeping the same value of the fraction.
We do this by first finding the greatest common factor of 15 and 60, which is 15.
Then, we divide both 15 and 60 by the greatest common factor to get the following simplified fraction:
1/4
which products result in difference of squares
(x-y)(y-x)
(6-y)(6-y)
(3+xz)(-3+xz)
(y^2-xy)(y^2+xy)
Answer:
[tex](3+xz)(-3+xz)[/tex]
[tex](y^2-xy)(y^2+xy)[/tex]
Step-by-step explanation:
The Difference of Squares
Any difference of two squared monomial results in a factored form like shown below:
[tex]a^2-b^2=(a-b)(a+b)[/tex]
Similarly:
[tex](a-b)(a+b)=a^2-b^2[/tex]
For a product of binomials to be a difference of squares, they must be in the described form.
------------------------
(x-y)(y-x) can be rewritten as:
-(x-y)(x-y)
Since both binomials are identicals, the product will not result in a difference of squares.
-----------------------
(6-y)(6-Y)
Since both binomials are identicals, the product will not result in a difference of squares.
-----------------------
(3+xz)(-3+xz) can be rewritten as:
(xz+3)(xz-3). This product is a sum multiplied by a difference of the very same terms, thus the result is a difference of squares:
[tex](3+xz)(-3+xz)=(xz)^2-9[/tex]
-----------------------
[tex](y^2-xy)(y^2+xy)[/tex]. This product is a sum multiplied by a difference of the very same terms, thus the result is a difference of squares:
[tex](y^2-xy)(y^2+xy)=y^4-(xy)^2[/tex]
-----------------------
Summarizing:
(3+xz)(-3+xz)
[tex](y^2-xy)(y^2+xy)[/tex]
