The greatest number of rows Silvia can plant as per given number of plants and condition is equal to 10.
As given in the question,
Silvia is going to plant 20 tomato plants and 30 bean plants.
Total tomato plants = 20
Total bean plants = 30
If Silvia would like to plant, the plants in rows where each row has the same number of tomato plants and each row has the same number of bean plants.
Then, the greatest number of rows Silvia can plant is equal to greatest common factor of 20 and 30.
20 = 2×2×5
30 = 2×3×5
Greatest common factor of 20 and 30 = 2×5 = 10
Therefore, the greatest number of rows Silvia can plant as per given number of plants and condition is equal to 10.

A jet ski rental charges a flat rate of $75, plus an additional $10 per hour. You only have $200 to spend. How many hours can you rent the jet ski?
PLS HELP ME
Answer:
12.5 hours
Step-by-step explanation:
The flat rate is the base, in which no matter how long you rent it for, they'll still charge you that much. You have 200 dollars, and negative 75 is 125 dollars, which you can spend on the hours. Assuming you can rent the jet ski for half an hour, you can divide 125 by 10 for the amount of hours, and the answer is 12.5 hours. However, if you can't rent the jet skis for half an hour, the answer is 12 hours.

The average speed of this particle over the interval 2 ≤ t ≤ 10 is 25 , the correct option is (b)25 .
In the question ,
it is given that
the position of the particle that travels along the x-axis at time t is given by the function
x(t)=2t²+t
the average speed of the particle can be calculated by using the formula
average speed = (change is distance)/(change in time)
particle position at t=2
x(2) = 2(2)²+2 = 2*4+2 = 10
particle position at t=10
x(10) = 2(10)²+(10)
= 2*100+10
= 200+10
= 210
So, change in distance = 210-10= 200
change in time = 10-2 = 8
Putting the values in the average speed formula we get
average speed = 200/8
= 100/4
=25
Therefore , the average speed of this particle over the interval 2 ≤ t ≤ 10 is 25 , the correct option is (b)25 .

If (1 - a) is decreased, the width of a confidence interval isA. Decreased B. Same C. Increased D. Constant
We have to find how the interval (1-α) affects the width of the confidence interval.
The interval (1-α) represents the confidence required for the interval.
The greater the confidence required, the wider will be the interval.
This means also that when we decrease the confidence required, the interval width decrease too, as we are less strict with the number of sample means that have to fall within that interval.
Then, when (1-α) decreases, the width of the confidence interval also decreases.

The coordinates of the point on the directed line segment are (-4, 4).
What is partitions of the segment?
Finding a position that is an equal distance from A and b equal distance from B is necessary for partitioning a line segment, AB, into a ratio of a/b.
Trying to find the coordinates of point that splits the line between (-7, -2) to (-2, 8) at a ratio of 3:2.
Since the ratio is 3:2 we are going o find the point that is 3/5 of the distance from (-7, -2) to (-2, 8).
For the x coordinate, find the distance between x coordinates (-2-(-7)) = 5.
Take 3/5 of 5 equals to 3 and add that to the first x coordinate (-7) to get the x - coordinate of interest -4.
For the y - coordinate, find the distance between y coordinates (8-(-2)) = 10.
Take 3/5 of 10 equals to 6 and add that to to the first y coordinate (-2) to get the y coordinate of interest 4.

Determinant of the matrix:
Determinant of the matrix is defined as a scalar value which is associated with the square matrix.
Given,
Here we have the matrix show in the question.
Now, we need to find the determinant of the matrix.
To find the determinant of the matrix we have to do the following steps:
1) First we have to pick any row or column in the matrix. It does not matter which row or which column you use, the answer will be the same for any row or column.
2) After the selection you have to multiply every element in that row or column by its cofactor and add. The result is the determinant.
This process can be elaborated in the following steps:
[tex]=(b+c)^2 \times ((a+c)^2 \times (a+b)^2 - b^2 \times c^2) -a^2 \times (b^2 \times (a+b)^2 - b^2 \times c^2) +a^2 \times (b^2 \times c^2 - (a+c)^2 \times c^2)[/tex]
When we expand the equation then we get,
[tex]=(b+c)^2 \times (a^4+2a^3b+2a^3c+a^2b^2+4a^2cb+c^2a^2+2c^2ab+c^2b^2+2acb^2 -b^2c^2) -a^2 \times(b^4+2b^3a+b^2a^2 -b^2c^2) +a^2 \times(b^2c^2 -c^4-2c^3a-c^2a^2)[/tex]
Group the similar terms and arrange them in order,
[tex]=(b+c)^2 \times (a^4+2a^3b+2a^3c+a^2b^2+4a^2cb+c^2a^2+2c^2ab+2acb^2) -a^2 \times (b^4+2b^3a+b^2a^2-b^2c^2) +a^2 \times (-c^4-2c^3a+b^2c^2-c^2a^2)[/tex]
Again we have to expand it and then we get,
[tex]= a^4b^2+2a^4bc+a^4c^2+c^4a^2+2c^4ab+2a^3b^3+6a^3b^2c+6a^3bc^2+2a^3c^3+6c^3ab^2+a^2b^4+6a^2b^3c+10a^2b^2c^2+6a^2c^3b+6c^2ab^3+2acb^4 -b^4a^2-2b^3a^3-b^2a^4+b^2c^2a^2 -c^4a^2-2c^3a^3+b^2c^2a^2-c^2a^4[/tex]
After the simplification, the resulting determinant is
[tex]=2a^4bc+2c^4ab+6a^3b^2c+6a^3bc^2+6c^3ab^2+6a^2b^3c+12a^2b^2c^2+6a^2c^3b+6c^2ab^3+2acb^4[/tex]
