Dino finds the line-of-best fit for the data set shown. What is the equation of Dino's line-of-best fit?
Answer:
y = 2.0x + 0.6
Step-by-step explanation:
Dino's data:
X _____ Y
1 ______ 1
2 ______5
3 ______6
4 _____ 10
5 _____ 13
6 _____ 13
7 _____ 14
8 _____ 16
9 _____ 18
10 _____21
Using the linear regression calculator, the line of best fit for the data is :
y = 2.0X + 0.6
Where ;
Slope = 2 ; intercept = 0.6
Write an equation of the line that passes through (1,2) and is parallel to the line y = -5x+4
Answer:
y =-5x + 7
Step-by-step explanation:
y = -5x + 4
Slope = -5
Parallel lines have same slope
Slope of the parallel line to this line = -5
(1 , 2)
y -y1 =m(x - x1)
y - 2 = -5(x - 1)
y -2 = -5x + 5
y = -5x + 5 + 2
y = -5x + 7

9/2 : 1/6 =
9/2 x 6/1 =
(9x6) / (2x1) =
54/2 = 27
a line is perpendicular to y=-2x+5 and intersects the point (-4,2). what is the equation of this perpendicular line?
Answer:
y = 1/2x + 4
Step-by-step explanation:
If the line is perpendicular to y = -2x + 5 then the new line has a slope of 1/2.
So solve for b: using y = mx + b
2 = 1/2(-4) + b
2 = -2 + b
4 = b
Put it all together
y = 1/2x + 4
Danny has at least $15 more than his big brother. Danny's brother has 72. How much money does Danny have?
Answer:
d >= $87
Step-by-step explanation:
Since we are not given the exact difference between the amount of money that Danny has in comparison to his brother, then this would ultimately be an inequality question. We are told that Danny has atleast $15 more than his brother, meaning that the minimum that Danny can have is $15 more than his brother. Danny's brother has $72 so we need to add these two values together.
$72 + $15 = $87
Therefore Danny would have a minimum of $87 but at the same time can have more than that. Therefore, we can use the following inequality to represent Danny's money (d)
d >= $87

Mrs. Zahid bought 6 bouquets at $ m each, and 8 packs of chocolates at $ ‘n’ each. She had $(2m + 5n) left. Find the amount of money she had at first.
Answer:
$(8m + 13n)
Step-by-step explanation:
Given that :
Total Cost of 6 bouquet = 6m
Total cost of 8 chocolate = 8n
Total amount spent = $(6m + 8n)
Total amount left = $(2m + 5n)
Hence, amount had at first :
Total amount. Spent + total amount. Left
(6m + 8n) + (2m + 5n)
(6m + 2m + 8n + 5n)
$(8m + 13n)
hello please help thank you!
Answer:
BC ≈ 5.44 m
Step-by-step explanation:
Using the cosine ratio in the right triangle
cosθ = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] , that is
cos27° = [tex]\frac{BC}{6.1}[/tex] ( multiply both sides by 6.1 )
6.1 × cos27° = BC , then
BC ≈ 5.44 m ( to 3 significant figures )

Write the equation for an exponential function that triples ever year, x, when the original amount is 4.
Answer:
y = 4(3)^x
Step-by-step explanation:
Here, we want to write the exponential equation
From the question, we have the equation tripling in x value every year and the original amount is 4
The exponential equation is of the form;
y = a(b)^n
In this case;
a = 4 , b = 3 and n = x
So we have the equation as;
y = 4(3)^x

$73 is what percent of $125
Answer: The question $73 out of 125 is 58.40%
Step-by-step explanation:
$73 out of 125 is what percent Answer: The question $73 out of 125 is 58.40%, which is the same as 73/125 as a percent. This can be solved using this calculator above
The $73 is approximately 58.4% of $125.
To find what percent $73 is of $125, we can use the following formula:
Percent = (Part / Whole) * 100
In this case, $73 is the part and $125 is the whole.
Substituting these values into the formula:
Percent = (73 / 125) * 100
Dividing 73 by 125:
Percent = 0.584 * 100
Multiplying 0.584 by 100:
Percent = 58.4
Therefore, $73 is approximately 58.4% of $125.
