Answer:
3383 Kg per hectare
Step-by-step explanation:
Given that:
Intercept and slope for a given regression equation is :
Intercept = 473 ; slope = 5
The dependent variable / predicted variable = rice yield (y)
The independent variable / predictor variable = annual Rainfall (x)
The regression model can be written has :
General form of a regression equation / model:
y = mx + c ; m = slope ; c = intercept
y = 5x + 473
predicted rice yield if the annual rainfall is 582 mm
y = 5(582) + 473
y = 2910 + 473
y = 3383 Kg per hectare
M= i + r ; solve for r
Answer:
m - i = r
Step-by-step explanation:
In this question, you are solving for "r".
Solve:
M= i + r
We have to get "r" by itself, so subtract "i" from both sides.
m - i = r
Since we found what "r" is, we can't solve any further.
m - i = r would be your answer.

Answer:
first car : 115 liters
second car: 135 liters
Answer:
car 1 = 173.08 liters
car 2 = 76.92 liters
Step-by-step explanation:
the first step is to find what ratio of car 1 is to car 2
that is 18:8
total ratio is 26
the combination of car 1 and 2 = 26
the total km = 3350
total fuel = 250 liters
car 1 = 18 x 250 liters
26
= 173.08 liters
car 2 = 8 x 250 liters
26
= 76.92 liters
173.08 + 76.92 = 250

The longer leg of a right triangle has a length of 15. One angle in the triangle is 60 degrees. What is the length of the shortest leg?
The shortest side of a right triangle with a hypotenuse of 15 and one angle of 60° is 7.5
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Given that the longer leg of a right triangle has a length of 15, hence hypotenuse = 15. One angle in the triangle is 60°. Let x represent the shortest side.
The shortest side is adjacent to the 60° angle, hence:
cos(60) = x / 15
x = 7.5
The shortest side of a right triangle with a hypotenuse of 15 and one angle of 60° is 7.5

what is 457.894 to 2 deimal places
Answer:
228.947
Step-by-step explanation:
Answer:
457.894
Step-by-step explanation:
"What is 457.894 rounded to 2 decimal places?" is the same as asking, "What is 457.894 rounded to two decimal points?" or "How to round 457.894 to two decimal places."
The main point is that you want to round 457.894 to two digits or places after the decimal point. Thus, we want to eliminate the last digit in 457.894. To eliminate the last digit in 457.894, we use the following Two Decimal Places Rules to get the answer:
Two Decimal Places Rule #1: If the last digit in 457.894 is less than 5, then remove the last digit.
Two Decimal Places Rule #2: If the last digit in 457.894 is 5 or more and the second to the last digit in 457.894 is less than 9, then remove the last digit and add 1 to the second to the last digit.
Two Decimal Places Rule #3: If the last digit in 457.894 is 5 or more and the second to the last digit in 457.894 is 9, and the third to the last digit is less than 9, then remove the last digit, make the second to last digit 0, and add 1 to the number to the third to the last digit.
Two Decimal Places Rule #4: If the last digit in 457.894 is 5 or more and the second to the last digit is 9, and the third to the last digit is 9, then add 1 to the number on the left side of the decimal point and make the right side of the decimal point 00.
When rounding 457.894 to two decimal places we use Two Decimal Places Rule #1. Therefore, the answer to "What is 457.894 rounded to 2 decimal places?" is:

Describe the transformations required to obtain the graph of the function f(x) from the graph of the function g(x).
f(x) = 9 cos x ; g(x) = cos x (3 points)
Answer:
The transformations required to obtain the graph of the function f(x) from the graph of the function g(x) is vertical stretch
Step-by-step explanation:
We need to describe the transformations required to obtain the graph of the function f(x) from the graph of the function g(x).
We have g(x) = cos x
After transformation we get
f(x)= 9 cos x
According to transformation rule:
if f(x) is transformed into a.f(x) then the transformation is vertical stretch or compression.
if a > 1 then transformation is vertical stretchif 0 < a < 1 then transformation is vertical compressionIn our case
g(x)= cos x
f(x) = 9 cos x
a=9 and a>1 so, the transformation is vertical stretch.
So, The transformations required to obtain the graph of the function f(x) from the graph of the function g(x) is vertical stretch

The coach for a basketball team wants to try I buy new shoes for her 12 players.
The same shoes are available on double dribble’s web site for $57.75. A 9% processing fee will be applied to the cost of the shoes, plus a shipping fee of $5.99 for each pair.
What is the difference in the total costs of the 12 pairs of shoes between the two sites?
The difference in the total costs of the 12 pairs of shoes between the two sites is $46.77,
How to find the cost difference and total cost?Total cost is the sum up cost for all the individual process. we can find it by adding the cost for each steps.
In the given ques,
Super Sports is offering a 20% discount.
and shoes were originally priced at $72.50 and that a 6.5% sales tax will be applied.
On Double Dribbles, the same shoes were on for $54.75, and a 9% is added and has an extra $5.99 for shipping.
i.e. we have to find the difference in the total costs..
Now we have to multiply 12 by 72.50. The answer to that is 870. Next, we need to multiply 8 by 870 and divide it by 10. The answer to that is 696. Then, we need to add the price and the tax. The price will be 100%, and the tax will be 6.5%. 100 + 6.5 = 106.5. After that, we need to 106.5 by 100. The answer it that is 1.065. Now do times 1.065 by 696. And the answer to that is $741.24.
Do the same for other store. The answer to it is 788.01.
Thus, making Super Sports a better deal.
As, we need to find the difference. So, 788.01 - 741.24 = $46.77.

use SSS, SAS, ASA, AAS or HL star if the two triangles are congruent, if they are state how you know?
Answer:HL, ASA, SSS, ASA
Step-by-step explanation:
1. HL because the hypotenuse are equal by the reflexive property and the at least one pair of legs are congruent. Also the interior angles are congruent.
2. ASA because the interior angles are both congruent and the included side is congruent by the reflexive property.
3. SSS because the corresponding sides are congruent and the line is congruent by reflexive property so all the sides are congruent.
4. ASA because the interior angles are congruent and the other pair of angles are also congruent because they are verticle angles. The including sides are also congruent so therefore angle-side-angle.
