Answer:
500
Step-by-step explanation:
she can build 5 in 6 minutes. 6 × 10 is 1 hour
so you would do 5 × 10 = 50
then multiply 50 × 10 hours = 500 toys
Answer:
Patricia will build 500 toys in 10 hours
Step-by-step explanation:
5 toys ? toys
--------- = ----------
6 minutes 10 hours
so we would turn the hours into minutes which would be
600 minutes.
5 toys ? toys
--------- = ----------
6 minutes 600 mins
Then we would cross multiply and that will give us how many toys she can build in 10 hours, which is 500 toys.

Answer:
The answer is A
Step-by-step explanation:
y=-0.5x + 225
This is because every month 50 cents which can be written as 0.5 is taken off the account so it would be negative. Since X = the number of months, you would multiply it by 0.5, hence -0.5x. Since 225 is the orginial balance you would add that.

hi guys if i have a bag of skittles and the order i specifically eat them in is red, orange, brown, yellow, green, blue
what will be the colour of the 39th skittle that i eat?
The order of the color of the 39th skittle is: yellow
How to solve order or position based problems?
By adding numbers to the given sequence and examining the repetition, order-based issues in mathematics can be addressed. Once the proper order number has been determined, numbering the other objects will be a breeze.
The answer is a bag of Skittles in the following color order: red, orange, brown, yellow, green, and blue.
The hue of the 39th skittle that they consumed is:
There are six hues in all.
Red is repeated once again after number 6. The order for the red is as follows:
[1, 6,12,18,24,30,36]
39 is yellow, 38 is brown, and 37 is orange.
Consequently, the 39th skittle is colored in the following order: yellow

given t : v ---- w as in exercise 47, and given a subspace z of w , jet u be the set of all x in v such that t (x) is in z . show that u is a subspace of v
The proof that "u" is a subspace of "v" is given below.
Suppose that t:v->w is a linear transformation where "v" and "w" are vector spaces.
Let "z" be the subspace of "w".
Since "t" is a linear transformation, the zero vector of "w" is in "z".
Let x, y ∈ U.
Then t(x), t(y) ∈ z.
Since, "z" is a subspace of "w".
So, "z" is closed under vector addition.
Thus, t(x) + t(y) ∈ z.
Now, t(x) + t(y) = t(x + y), since, t is a linear transformation.
Therefore, t(x + y) ∈ z.
Thus, x + y ∈ u.
Therefore, "u" is closed under vector addition.
Hence proved.

Which statement is true?
There is a weak positive association between the variables.
There is a weak negative association between the variables.
There is strong positive association between the variables.
There is a strong negative association between the variables.
There is strong positive association between the variables.
What is meant correlation coefficient between two variables?The strength of the linear link between two variables is assessed using correlation coefficients. A correlation coefficient with a value over zero denotes a positive link, whereas one with a value below zero denotes a negative relationship. A statistical indicator of how strongly two variables are linearly related is the correlation coefficient. From -1 to 1, its values are possible. A correlation coefficient of -1 indicates a perfect negative, or inverse, correlation, in which the values in one series rise as the values in the other fall, and the other way around. A value of 1 indicates a direct link that is 100 percent positive. There is no linear link when the correlation coefficient is zero.

The plane that contains the rays contains the angles created by two rays.Depending on the measurement, there are various angles in geometry.

1) Find the table
To find the numbers on the table, just substitute the number for x
If x = 0
y=-4x+3
y=-4(0) + 3
y= 0 + 3
y= 3
If x = 1
y=-4x+3
y=-4(1)+3
y= -4 + 3
y= -1
You can see a pattern, each x makes it go down by 4.
So the following will be...
if x = 2 -> -5
if x = 3 -> -9
2) Now fill in the table with the points

For students who earned a score of 21 or higher on the quiz
The cumulative frequency = 16
The relative frequency = 32%
The number of times a specific value appears in the data is its frequency (f). A variable's distribution is its frequency pattern, or the collection of all conceivable values and the frequencies corresponding to those values.
To get relative frequency, we will take this cumulative number and divide by the total number of students. number of 21 or more / total number of students = 16 / 50 = 0.32 or 32%.
The cumulative frequency of students who earned a score of 21 or higher on the quiz is =16.
