Which equation best represents a trend line for the scatter plot? These are fractions BTW.
y=−7/6x+55/6
y=−6/7x+62/7
y=7/6x+41/6
y=6/7x+50/7
The equation that best represents a trend line for the scatter plot is y=−7/6 x+55/6
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
where (x₁, y₁) and (x₂, y₂) are the two points that you are trying to find the slope between.
We are given the points (1, 8) and (7,1) on the scatter plot.
Therefore, the slope = (8-1)/(1-7) = -7/6
Now, the equation of line;
y = mx + b
b = y - mx
b = 8 - (-7/6)(1)
b = 8 + 7/6
b = 55/6
The equation becomes;
y = -7/6(x) + 55/6
The answer is y=−7/6 x+55/6

A cathedral has a large,circular stained glass window. A visitor measures the window and calculates that it has a circumference of 12.56 yards. What is the windows area
The area of the stained glass window is approximately 12.56 square yards. We obtained this by first calculating the radius (2 yards) using the given circumference, then substituting the radius into the formula for the area (πr²).
Explanation:The area of a circle can be found using the formula A = πr². where A represents the area, r is the radius, and π is a mathematical constant approximately equal to 3.14. First, we should find the radius of the window. The circumference of a circle is given by the formula C = 2πr. If the circumference is known to be 12.56 yards, we can solve for the radius as follows:
Setting the two formulas equal to each other, we get 12.56 = 2πrDividing both sides by 2π, we get r = 12.56/2π = 2 yards.Next, we substitute the radius into the area formula: A = π(2)² = 4π = 12.56 square yards.

The value of an autographed baseball card increased from $39 to $65. What is the percent increase in value of the baseball card? Round to the nearest hundredth of a percent
Answer:
The percent increase in value of the baseball card is 66.667%
Step-by-step explanation:
You must first determine the amount of money increased by the value of an autographed baseball card. For this you must subtract the price with the applied increase and the original price of the card: $65-$39=$26
This will be the amount of increase. Then, one way to calculate the percentage increase in the value of the baseball card is through a direct rule of three.
The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three. Remember that proportionality is a constant relationship or ratio between different magnitudes.
If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (Or when one magnitude decreases, so does the other), the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:
a ⇒ b
c ⇒ x
Then
[tex]x=\frac{c*b}{a}[/tex]
In this case, the rule of three applies as follows: If the original price ($ 39) represents 100%, what is the value of the percentage in the value of the baseball card when its value increases $ 26?
[tex]percentage=\frac{26*100}{39}[/tex]
percentage=66.667%
Another way of thinking about it is considering that:
change from the original price = percentage of change*original price
In this case: $26=percentage of change*$39
So, isolating the percentage of change you get:
[tex]percentage of change=\frac{26}{39} =0.66667[/tex]
This value is expressed in decimal, and for it to be expressed in fraction you must multiply it by 100 (100%). Then you get:
percentage of change=0.66667*100%
percentage of change=66.667%
Note that the value obtained is the same as in the previous case, so both ways of thinking the solution to this problem is correct
Finally, the percent increase in value of the baseball card is 66.667%

Molly invested $12,000 in an account with an interest rate of 6%. What is the amount in Molly's account after 6 years if the interest was compounded annually? A) $5,022.23 B) $17,022.23 C) $22,044.46 D) $170,222.26
The formula for compound interest is given by:
[tex] A = P (1+\frac{r}{n})^{nt} [/tex]
where ,
A= Amount,
P=Principal
r=rate of interest
n= number of times interest is compounded per year
t = time ( in years)
Plugging the values ,
P = $12,000
r=0.06
t=6 years
n=1(annually compounded)
Plugging these in the formula,
[tex] A = 12000 (1+\frac{0.06}{1})^{1*6} [/tex]
A =$17022.229 which is approximately 17022.23

What simplified ratio correctly compares 10,000 centimeters to 1000 meters? Drag and drop the appropriate numbers into the boxes
For this case, the first thing we must do is to have the same units for both measures.
We have then that by definition:
[tex]1m = 100cm[/tex]
Therefore we have:
[tex]10,000cm * (\frac {1m} {100cm}) = 100m[/tex]
Then, we look for the relationship between both measures:
[tex](\frac {100m} {1000m})[/tex]
Simplifying we have:
[tex](\frac {1m} {10m})[/tex]
Answer:
The simplified ratio that correctly compares 10,000 centimeters to 1000 meters is:
[tex](\frac {1m} {10m})[/tex]
a taxi service charges an initial fee plus $1.80 per mile. how far can you travel for $12
To travel for $12 in a taxi service with an initial fee plus $1.80 per mile, you can travel up to 3 miles.
Explanation:To determine how far you can travel for $12, you need to consider the initial fee charged by the taxi service and the cost per mile. Let's assume the initial fee is $5. Therefore, you have $12 - $5 = $7 left to spend on miles. Since the cost per mile is $1.80, you can travel $7/$1.80 = 3.89 miles. However, since you cannot travel a fraction of a mile, you can travel up to 3 miles for $12.

a boy flies a kite with 100 foot long string. the angle of elevation of the string is 48. how high is the kite from the ground.
The height of the kite from the ground is approximately 74.2 feet, calculated using the trigonometric concept of sine. Sine of an angle in a right triangle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.
Explanation:The subject of the question is the height of a kite, a topic in Trigonometry.Trigonometry deals with the relationships between the sides and angles of triangles. In this case, we're given that a boy is flying a kite with a 100 foot string at an angle of 48 degrees. We can use the concept of sine in Trigonometry, where sine of an angle in a right triangle is the length of the opposite side divided by the length of the hypotenuse.
In this case, the height of the kite from the ground forms the opposite side, the 100 foot string forms the hypotenuse, and the angle of elevation given is 48 degrees. We have the equation:
sin(48) = height / 100
Therefore, the height = sin(48) * 100.
Using a calculator to find the sine of 48 degrees, and then multiplying the result by 100, we get the height of the kite from the ground to be approximately 74.2 feet.
