The ratio of flower seeds to the total amount of seeds is 2/7 = 0.2857.
What is meant by GCF?The greatest common divisor of two or more numbers that are not all equal to zero is the largest positive integer that divides each of the integers. This term is used in mathematics. The symbol represents the two integers x and y's greatest common factor. The GCF of two or more numbers is the greatest number among all the common factors of the given numbers.
Given that,
The local stores have donated 30 packets of flower seeds and 105 packets of vegetable seeds.
30/105
We have to find the GCF of 30 and 105=15
30/15=2
105/15=7
So, the answer is 2/7
The ratio of flower seeds to the total amount of seeds is 2/7.

a sample survey interviews an srs of 209 college women. suppose that 69% of all college women have been on a diet within the last 12 months. what is the probability that 72% or more of the women in the sample have been on a diet? report your answer using 4 decimal places.
The probability that 72% or more of the women in the sample have been on a diet is, 0.1736.
What is probability?
Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is.
As given a sample survey interviews an SRS of 209 college women. suppose that 69% of all college women have been on a diet within the last 12 months.
p = 0.69
1 - p = 0.31
n = 209
μp = p = 0.69
σp = √(p(1-p))/n = √(0.69*0.31)/209 = 0.03199
= 1 - p(p < 0.72)
= 1 - p((p - μp) / σp < (0.72 - 0.69) / 0.03199)
= 1 - p(z < 0.94)
= 1 - 0.8264
= 0.1736
Hence, the probability is 0.1736.

Answer:
1. 30 years old
2. 7 years old
3. 5 hours
Step-by-step explanation:
We can solve all of these problems using algebraic equations.
1. In this question, we will use variable x to represent the age of Mrs. Olsen's daughter.
In 10 years, x - 20 = 2x. That means that in 10 years, Mrs. Olsen will be 40 years old. That means she is 30 right now.
2. In this question, we will use variable x to represent the age of Alyssa.
If, in 30 years, their total age is 88, their current total is 28. Tyler is 3 times as old as Alyssa, so Tyler is 21 and Alyssa is 7.
3. Ryan leaves home at 50 mph. That means, in an hour Ryan will be 50 miles away from home. At that point, Jacob leaves home at a speed of 60 mph, so the gap between them closes by 10 miles each hour. That means that Jacob will take 5 hours to catch up, counting from when he left (how far is this workplace jeez?!?!?!?).
We could also represent this with a graph.
Hour 1: R = 50, J = 0 (Jacob leaves after this hour so it doesn't count for the answer)
Hour 2: R = 100, J = 60
Hour 3: R = 150, J = 120
Hour 4: R = 200, J = 180
Hour 5: R = 250, J = 240
Hour 6: R = 300, J = 300

3, –5 + 2i, –5 – 2i
–3, 5 + 2i, 5 – 2i
–3, –5 + 2i, –5 – 2i
The solutions to the expression x³ + 87 = 7x² + x are given as follows:
–3, 5 + 2i, 5 – 2i.
How to obtain the solutions to the equation?The equation is defined as follows:
x³ + 87 = 7x² + x.
In standard format, it is given by:
x³ - 7x² - x + 87 = 0.
It has one negative solution, hence from the options it is:
x = -3.
The verification is:
(-3)³ - 7(3)² - (-3) + 87 = 0.
Considering the linear factor (x + 3), the function can be written as follows:
x³ - 7x² - x + 87 = (x + 3)(ax² + bx + c).
As the product of a linear function and a quadratic function results in a cubic function.
Expanding the right side of the equality, we have that:
ax³ + (b + 3a)x² + (3b + c)x + 3c = x³ - 7x² - x + 87.
Hence the coefficients of the quadratic equation are given as follows:
a = 1.b + 3a = -7 -> b = -10.c = 87/3 = 29.Hence the equation is:
x² - 10x + 29 = 0.
And the solutions, using a quadratic equation calculator, are given as follows:
x = 5 + 2i.x = 5 - 2i.Which means that the third option is correct.

Find the component form of the vector that translates (3, − 2) to ′(− 1, 4)
The vector that translates P to P' is (-4 , 6)
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x).
The points are given;
[tex]{P = (3, -2)}\\{P' = (-1, 4)}[/tex]
The translation rule is calculated as:
{(x,y) = P' - P}
So, we have:

5,10,20 Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form.
The given sequence is geometric sequence not arithmetic.
What is arithmetic sequence?An arithmetic sequence is a sequence in which the difference between every two consecutive terms is constant
What is the geometric sequence?A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value. It is found by taking any term in the sequence and dividing it by its preceding term.
Difference between arithmetic and geometric sequence:
An arithmetic sequence has a constant difference between each consecutive pair of terms
while
A geometric sequence has a constant ratio between each pair of consecutive terms.
Here, we have a sequence 5,10,20.
So a₁ = 5, a₂ = 10, a₃ = 20
Difference = a₃- a₂ = 20 - 0 = 10
a₂ - a₁ = 10 - 5 = 5
Since the difference is not constant, therefore the given sequence is not arithmetic.
Now ratio a₃/a₂ = 20/10 =2 and a₂/a₁ = 10/5 =2 which is same which shows the sequence is geometric.
Therefore, the sequence is geometric sequence.

Today, Austin's age
is 1/4 of Stephanie's
age. In 4 years,
Austin's age will be
2/5 of Stephanie's age.
How old is Stephanie
today?
Answer: Steph is 16 today
Step-by-step explanation:
Austin age today = x
Austin in 4 years = x+4
Steph age today = 4x (because Austin is 1/4 her age today)
Steph age in 4 years is 4x + 4
In 4 years Austin's age is 2/5 of Steph's, so:
2/5 (x+4) = 4x + 4
Now solve for x!
x+4 = (8/5)x + 8/5
12/5 = (3/5)x
Therefore Austin is 4 years old today (x=4) and...
Steph age today = 4x = 4x4 = 16

children attended.
Using simplification, if the total ticket sales was $1316, then 70 children, 78 students and 35 students attended.
From the given question,
We know that the capacity of movie theater is 183.
The theater charges $5.00 for children, $7.00 for students and $12.00 of adults.
There are half as many adults as there are children.
If the total ticket sales was $1316, then we have to find how many children, students, and adults attended.
Let the number of children that attended = x
Since, there are half as many adults as children.
Therefore number of adults = 1/2x =0.5x
We know there are total of 183 tickets
Therefore number of students = 183 - x - 0.5x
number of students = 183 - 1.5x
Each children ticket costs = $5
Then the price of children tickets = 5x
Similarly for adults each ticket costs = $12
So total cost of adult ticket = 12×0.5x = $6x
Now the cost of student tickets = 7(183 - 1.5x)
As given that
Total cost of all tickets = $1316
So the expression should be
5x + 6x + 7(183 -1.5x) = 1316
Simplifying
11x + 1281 - 10.5x = 1316
Subtract 1281 on both side
11x + 1281 - 10.5x-1281 = 1316-1281
Simplifying
0.5x = 35
Divide by 0.5 on both side we get
x = 70 children
Now finding the number of adults
= 0.5x
= 0.5×70
= 35 adults
Now finding the number of students
= 183 - 1.5x
= 183 - 1.5×70
= 183 - 105
= 78 students
Hence, If the total ticket sales was $1316, then 70 children, 78 students and 35 students attended.

Answer:
Step-by-step explanation:
this slope of a line question is such a common question. I feel like math teachers all over don't understand how to teach this subject. Just so you know, I answer a question like this about 10 times a day when I am on here. It's like one of the most common questions.
Here is my copy and paste answer for this...
point P1 (-3,7.2) in the form (x1,y1)
point P2(2,-2.3) in the form (x2,y2)
slope = m
m = (y2-y1) / (x2-x1)
m = (-2.3-7.2) / (2-(-3))
notice all the minus signs and how i'm being very careful to keep close track of them. Also, who ever has written this question is intentionally trying to trip you up by putting in all the minus signs, there is no need for so many minus signs to teach this well. Anyway...
m = -8.5 / 5
m = - 1.7
the problem question ends there , but there is a common place this question is supposed to take you. to the point slope formula. but for another question.
The slope of (-3, 7.2) and (2, -2.3) is -1.9.
Consider,
(x1, y1) = (-3, 7.2)
(x2, y2) = (2, -2.3)
slope = (y2 - y1)/(x2-x1)
slope = ((-2.3) - (7.2))/((2) - (-3))
slope = (-9.5)/(5)
slope = -1.9
Therefore, the slope of the given points (-3, 7.2) and (2, -2.3) is -1.9.

The perimeter of a rectangle is 150 inches. The width is 12 inches. Find the length.
Answer:
63 inches
Step-by-step explanation:
The perimeter of a rectangle is found by adding all of the side lengths. Since both pairs of opposite sides have the same length, an equation for the perimeter can be written like this:
[tex]P=2w+2l[/tex]
Where w and l represent the width and length.
Since we are asked to find the length, rewrite the equation in terms of l:
[tex]l=\frac{P-2w}{2}[/tex]
We know the values for P and w, so plug those in:
[tex]l=\frac{150-2(12)}{2}[/tex]
Now simplify!
[tex]l=\frac{126}{2}=63[/tex]
Answer:
l = 63 in
Step-by-step explanation: If the P=150 in W=12 in so .... using the formula P=2 (l + w) you get L= P/2 - W = 150/2 - 12 = 63 in. I hope this helps!
What is an equation of the line that passes through the point (3,-1)(3,−1) and is parallel to the line 5x+3y=6
Answer: y=-5/3x+4
Step-by-step explanation:
Since the line is parrallel that means that the gradient is the same
We can reorder 5x+3y=6 into 3y=-5x+6 but in order to find the gradient the number infront of y must be 1 so...
3y=-5x+6
y=-5/3x+2
Now we know that the gradient is -5/3
To find th y-intercept we just subsitute the points it passes through (3, -1) into the equation
y=-5/3x+c
-1=-5/3(3)+c
-1=-5+c
