The best describes the relationship between x and y will be;
⇒ Strong negative correlation.
What is linear expression?A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
The results of a linear regression are shown below,
⇒ y = ax + b
⇒ a = -1.15785
⇒ b = 139.3171772
⇒ r = -0.896557832
⇒ r₂ = 0.8038159461
Now,
With the value of r we have both the information about the sign of the relationship and the strength of this relationship.
⇒ As the value of r is negative, we can conclude that the correlation between x and y is negative.
Also, as the absolute value of r is close to 1, we can conclude that this relationship is strong.
And, The strength can also be seen in the value of r2, which is also close to 1, but this value does not give information about the sign.
Thus, The value of the slope a, being negative, can also tell us that the relation between x and y is a negative correlation.

Tasha is packing gift bags that include
the same items. She has 72 glow sticks,
36 markers, and 24 bottles of bubbles.
Tasha believes that she can pack no
more than 6 bags using all of her
supplies. Do you agree with Tasha? Explain.
Answer:
No, I do not.
She can pack up to 12 bags
Step-by-step explanation:
Given
[tex]Glow\ sticks = 72[/tex]
[tex]Markers = 36[/tex]
[tex]Bubbles = 24[/tex]
Required
Is Tasha correct?
The maximum number of bags she can pack is determined by the greatest common factors (GCF) of the items.
i.e. GCF of 72, 36 and 24.
This is calculated as:
[tex]24 = 2*2*2*3[/tex]
[tex]36 = 2 * 2 *3*3[/tex]
[tex]72 = 2 * 2 * 2 *3*3[/tex]
Multiply all common factors:
[tex]GCF = 2 * 2 * 3[/tex]
[tex]GCF = 12[/tex]
The GCF is 12.
This implies that she can pack up to 12 bags

The price of oil decreased from $52 per barrel to $48 per barrel. What is the percentage decrease in the price of oil? Round your answer to the nearest tenth of a percent.
Answer:
7.7%
Step-by-step explanation:
Given that,
The price of oil decreased from $52 per barrel to $48 per barrel.
We need to find the percentage decrease in the price of oil. It can be calculated as follows :
[tex]\%=\dfrac{52-48}{52}\times 100\\\\=7.69\%[/tex]
or
= 7.7%
So, the percentage decrease in the price of oil is 7.7%.

It has been estimated that a certain stream can support 85,000 fish if it is pollution-free. It has further been estimated that for each ton of pollutants in the stream, 1700 fewer fish can be supported. Assuming the relationship is linear, write the equation that gives the population of fish p in terms of the tons of pollutants x.
Answer:
[tex]p = 85000 - 1700x[/tex]
Step-by-step explanation:
Given
[tex]Initial\ Fish = 85000[/tex]
[tex]Rate = 1700[/tex]
Required
Determine the equation
For 1 ton, there is a reduction of 1700 fishes
This implies that:
For x tons, there will be a reduction of 1700x fishes
So, the function is:
[tex]p = Initial\ Fishes - Rate * x[/tex]
We used minus because the number of fishes reduced.
So, we have:
[tex]p = 85000 - 1700*x[/tex]
[tex]p = 85000 - 1700x[/tex]
Hence, the function is: [tex]p = 85000 - 1700x[/tex]

Suppose the half-life of a certain radioactive substance is 20 days and there are 50g present initially.
a)
Write an equation that models this situation.
b)
How much radioactive substance is remaining after 12 days?
c)
Find the time when there will be 1g of the substance remaining.
Answer:
a) 10(5g + 2r) weight loss over time
b) 20/12 = 1.66667 = 50 / 1.67 = 29.999 gm = 5(6g -1/50) or 5(5 + g) = 30g
c) 30g = 12 days = 3/5 therefore 5/5 -3/5 = 2/5 = 2/5 x 50 (g) = 20g in 8 days lost
8/20 = 0.4 loss each day 50g - 0.8g = 20-2 = 18 days.

Write the coordinates of the vertices after a rotation of 90 degrees counterclockwise around the origin.
Answer:
U(2, 7) → U'(-7, 2)
V(10, 7) → V'(-7, 10)
W(2, 3) → W'(-3, 2)
Step-by-step explanation:
From the picture attached,
Coordinates of the vertices of the given triangle,
U → (2, 7)
V → (10. 7)
W → (2, 3)
Since rule for the coordinates of a point P(x, y) after a rotation of 90° counterclockwise about the origin is,
P(x, y) → P'(-y, x)
Here point P is the preimage and P' is the image point after rotation.
By this rule,
U(2, 7) → U'(-7, 2)
V(10, 7) → V'(-7, 10)
W(2, 3) → W'(-3, 2)
