Answer:
y = 0.762x + 1.72
Step-by-step explanation:
Given the data above , the regression model obtained using a Pearson linear regression calculator is :
y = 0.762x + 1.72
The regression equation cloud be interpreted as follows :
Slope, which is the increase in the value of y per unit increase in x = 0.762
The intercwpt, which is the value of x when y = 0 is 1.72

Several minutes later, Raul decides to measure the water temperature again. He finds that the temperature changed by -0.6°F. What is the temperature of the water now? Show your work.
The current temperature of the water is given as follows:
71.7 ºF.
How to obtain the current temperature of the water?The defining statement from the problem is given as follows:
He finds that the temperature changed by -0.6°F.
The change by the negative amount of -0.6ºF means that the current temperature of the water is obtained subtracting the previous temperature of the water by 0.6 ºF.
The previous temperature of the water is given as follows:
72.3°F.
Hence the current temperature of the water is obtained subtracting 72.3ºF and 0.6ºF, as follows:
72.3 - 0.6 = 71.7 ºF.
Missing InformationThe previous temperature of the water is given as follows:
72.3°F.

Christopher measured a line to be 12.2 inches long. If the actual length of the line is 12.1 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?
If Christopher measured a line to be 12.2 inches long. If the actual length of the line is 12.1 inches, the percent error of the measurement, to the nearest tenth of a percent is: 0.83%.
How to find the percent error?Using this formula to find the percent error
Percent error = Measurement - Actual length / Actual length
Let plug in the formula
Percent error = 12.2 - 12.1 / 12.1
Percent error = 0.1 /12.1
Percent error = 0.0083 or 0.83%
Therefore we can conclude that the percent error is 0.83%.

y is inversely proportional to x
when y = 7, x = 9
a) work out an equation connecting y and x
b) work out the value of y when x = 21
The equation connecting y and x is y = 63/x and the value of y when x =21 is 3
a) work out an equation connecting y and xFrom the question, we have the following parameters that can be used in our computation:
Variation = inverse variation
y = 7, x = 9
An inverse variation is represented as
k = xy
Where k is the constant of proportion
Substitute the known values in the above equation, so, we have the following representation
k = 7 * 9
Evaluate
k = 63
So, we have the following representation
xy = 63
Make y the subject
y = 63/x
b) work out the value of y when x = 21Substitute the known values in the above equation, so, we have the following representation
y = 63/21
Evaluate
y = 3
Hence, the solution is 3

julio has 13 red marbles 4 blue mables and 8 yellow marbles julio draws a marble out of the bag 100 times how many time out of 100 can julio expect a blue marble
Answer:
16 times
Step-by-step explanation:
13 + 4 +8 = 25 total marbles
(4 is total number of blue marbles, 25 is complete total of marbles)
4/25 times = ?/100 times
Because 25 times 4 is equal to 100, you then multiply 4 by 4 to get 16

Answer:
48,213
Step-by-step explanation:
The full answer is 48,212.5367, but because there is a 5 in the tenths place you round the whole number up
9514 1404 393
Answer:
49,000
Step-by-step explanation:
The divisor is 4.084. When it is rounded to the nearest whole number, it is 4.
Then the division problem becomes ...
196,900/4 ≈ 49,000 . . . . . . showing just 2 significant digits for the estimate
__
The point of an estimate is to obtain an approximate answer that is within a few percent of the actual answer. Here, rounding 4.084 to 4.000 gives an error on the order of .084/4 ≈ 2.1%. Because we're using a smaller divisor, the value we obtain for our estimate will be too large by about that amount.
Often, an estimate that has 1 or 2 significant digits is "close enough" for the purpose. Because a change in our estimated value of 1 in the least significant digit is a change of about 2%, we judge this estimate to be "close enough", given the rounding we did to start. Keeping 3 significant digits in our estimate would claim an accuracy that it does not have.

9. Marcus vegetable is drawing a plan for his garden. He graphs one corner at (-7.2, 2). He reflects (-7.2, 2) across the x-axis. Then Marcus reflects the new points across the y-axis. What shape is the vegetable garden?
Answer: To reflect a point across the x-axis, you need to change the sign of the y-coordinate. Therefore, the point (-7.2, 2) reflected across the x-axis becomes (-7.2, -2).
To reflect a point across the y-axis, you need to change the sign of the x-coordinate. Therefore, the point (-7.2, -2) reflected across the y-axis becomes (7.2, -2).
The resulting shape is a rectangle with one corner at (-7.2, 2) and the opposite corner at (7.2, -2).

Every time an insect jump forward the distance covered is half of previous jump. if the insect initially jumped 8.4cm calculate to the nearest two decimal places distance of sixth jump
The distance that he jumped in the sixth jump nearest to two decimal places will be 0.13.
What is a geometric sequence?Let a₁ be the first term and r be the common ratio.
Then the nth term of the geometric sequence is given as,
aₙ = a₁ · (r)ⁿ⁻¹
Every time an insect jump forward, the distance covered is half of the previous jump. If the insect initially jumped 8.4 cm.
The equation is given as,
aₙ = 8.4 · (1/2)ⁿ⁻¹
The distance that he jumped in the sixth jump will be given as,
a₆ = 8.4 · (1/2)⁶⁻¹
a₆ = 8.4 / 64
a₆ = 0.13125
a₆ ≈ 0.13
The distance that he jumped in the sixth jump nearest to two decimal places will be 0.13.

What is the length of AB and the coordinates of its midpoint?
AB= __ units
the midpoint of AB is (_,_)
The length of AB would be = 10 units and the midpoint of segment AB would be (-5, 2).
What are the distance formula and midpoint of a segment?
The distance formula is a mathematical formula that can be used to determine the distance between two points in a coordinate plane. The distance between two points (x1, y1) and (x2, y2) is given by the formula:
[tex]d = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]
The midpoint of a segment is a point that is exactly in the middle of a line segment. Given the endpoints of the line segment, (x1, y1) and (x2, y2) the coordinates of the midpoint, (x, y) can be calculated using the following formulas:
x = (x1 + x2) / 2
y = (y1 + y2) / 2
The given points are (-8, 6) and (-2, -2).
Given two points A(x1, y1) = (-8, 6) and B(x2, y2) = (-2, -2), we can use the distance formula to find the length of the line segment AB. The distance formula is:
[tex]d = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}\\\\d= \sqrt{((-2) - (-8))^2 + ((-2) - (6))^2}\\\\d=\sqrt{36 + 64}\\\\d=\sqrt{100}\\\\d=10[/tex]
The length of AB would be 10.
To find the coordinates of the midpoint of AB, we can use the midpoint formula:
x = (x1 + x2) / 2
y = (y1 + y2) / 2
Plugging in the values for A and B, we get:
x = (-8 + (-2)) / 2 = -5
y = (6 + (-2)) / 2 = 2
The coordinates of the midpoint of AB are (-5, 2).
Hence, the length of AB would be = 10 units and the midpoint of segment AB would be (-5, 2).
