Scatter plot is missing, so i have attached it.
Answer:
C : zero correlation
Step-by-step explanation:
A correlation is said to be negative between two variables when they are related in such a manner that when one variable increases, the other variable decreases and vice versa.
However, a correlation is said to be Positive when one variable increases as the other increases as well and vice versa which means they both move in the same direction.
However, in the image of the scatter plot attached, we see that it is neither positive or negative correlation as there is no clear visible relationship between the variables on the x and y axis.
Thus, we can say there is zero correlation.

Hakeem went shopping for a new pair of sneakers because of a sale. The store was offering a 40% discount. What number should he multiply the prices on the tags by to find the price he would have to pay, before tax, in one step?
Answer: 60% or 0.6
Step-by-step explanation:
A discount simply means the amount that is deducted from the normal cost of a good or service.
In the question above, the store was offering 40% as discount, this means that he'll only pay 60% of the price of the good. Note that (100% - 40% = 60%).
Therefore, the number that he should multiply the prices on the tags by to find the price he would have to pay will be 60% = 0.6.
A plane takes off and climbs at a 10º angle. After flying over 12 miles of ground, what will the plane's altitude, h, be? Round to the nearest tenth of a mile.
=========================================================
Explanation:
A diagram is optional, but I find it helps sometimes. The diagram is shown below.
Opposite the 10 degree angle is h. So we consider h the opposite side.
The hypotenuse is 12. The hypotenuse is always opposite the 90 degree angle.
Apply the sine ratio to solve for h
sin(angle) = opposite/hypotenuse
sin(10) = h/12
12*sin(10) = h
h = 12*sin(10)
h = 2.08377813200317 which is approximate
h = 2.1 miles is the plane's altitude which is also approximate
Side note: 2.1 miles is equal to 11,088 feet (multiply by 5280 to convert from miles to feet).
Can someone answer my question please
Answer:
Step-by-step explanation:
Arc length=∅/360×2πr (can't find the symbol of theta, use ∅ instead LOL)
[tex]\frac{\theta }{360}\cdot 2\pi \left(11\right)=16[/tex]
[tex]\frac{\theta }{360}=\frac{16}{22\pi }[/tex]
[tex]\theta \:=\frac{16}{22\pi \:}\cdot 360[/tex]
[tex]{\theta}=83.34[/tex]
Answer:
≈ 1.5 radians
Step-by-step explanation:
The arc length is calculated as
arc = circumference of circle × fraction of circle
Here arc = 16 , then
2πr × [tex]\frac{0}{2\pi }[/tex] = 16 ← cancel the 2π on numerator/denominator
11 ×θ = 16 ( divide both sides by 11 )
θ ≈ 1.5 radians ( to the nearest tenth )
for a cube with side length 4cm, calculate the surface area
Answer: I believe that’s 96 squared cm

A line has a slope of 3/5. It passes through the points (1, 2) and ( k, 8). What is the value of k?
A. 7
B. 11
C. 8
D. 15
Answer:
B. 11
Step-by-step explanation:
Delta y over delta x
(8-2)/(k-1) = 3/5
6/(k-1) =3/5
6 = 3/5k - 3/5
6 3/5 = 3/5k
K = 11

paz and her scout troop makes 325 granola bars for a fundraiser. four granola bars are put in each bag. paz says that there will not be any left over. find and correct her mistake.
Answer:
Her mistake was in how many bags would be able to equally hold 4 bars.
325/4 is 81.25, which would mean there needs to be 82 bags, in which you wouldnt be able to hold 4 each equally.
A better option for Paz is to put 5 bars in each bag as 325 is an even multiple of 5. As such would result in the bag count being brought down to 65 bags to evenly hold all of the bars.
Hope this helped!
evaluate functions from their graph g(7)
Answer:
Evaluate functions from their graph g(7)= 4
Step-by-step explanation:
If the point (a,b)(a,b)left parenthesis, a, comma, b, right parenthesis is on the graph, then g(a)=bg(a)=bg, left parenthesis, a, right parenthesis, equals, b.
We should look for the point on the graph whose x-coordinate is 7.
The point on the graph whose xxx-coordinate is 7 is the point (7,4)
Therefore, g(7)=4.
please help me i will give you brainlyest(or however you spell it) ANSWER SERIOUSLY
x=11 should be the answer lmk if so
Answer:
x = 18
Step-by-step explanation:
m∠1 & m∠3 are vertical angles. By definition of vertical angles, their measurements will be the same.
It is given that:
m∠1 = 4x - 14
m∠3 = 58°
Set the two angles equal to each other:
4x - 14 = 58
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 14 to both sides of the equation:
4x - 14 (+14) = 58 (+14)
4x = 72
Next, divide 4 from both sides of the equation:
(4x)/4 = (72)/4
x = 72/4 = 18
18 is your answer for x.

five books cost¢21. what is the price cost of seven similar books
Answer:
Your answer should be $29.40
Step-by-step explanation:
If you divide 21 by 5 you get 4.2, so each book costs $4.20.
4.2 x 7 = 29.4
Therefore, your total cost for 7 books will be $29.40
I hope this helps!

Vlad spent 20 minutes on his history homework and then completely solved x math problems that each took 2 minutes to complete. What is the equation that can be used to find the value of y, the total time that Vlad spent on his homework, and what are the constraints on the values of x and y?
y=2x+20; x is any integer greater than or equal to 0, and y is an integer greater than or equal to 20.
y=2x+20; x is any real number greater than or equal to 0, and y is any real number greater than or equal to 20.
y=20x+2; x is any integer greater than or equal to 0, and y is an integer greater than or equal to 20.
y=20x +2; x is any real number greater than or equal to 0, and y is any real number greater than or equal to 20.
Answer:
The answer is A. y = 2x + 20; x is any integer greater than or equal to, 0 and y is any integer greater than or equal to 20

Here , we are going to use Trigonometric ratios.
In given right angled ∆ ;
[tex]{:\implies \quad \sf \dfrac{x}{18}=\sin (60^{\circ}) \quad \bigg\{ \because \sin (\theta)=\dfrac{P}{H}\bigg\}}[/tex]
[tex]{:\implies \quad \sf x=\dfrac{18\sqrt{3}}{2} \quad \bigg\{\because \sin (60^{\circ})=\dfrac{\sqrt{3}}{2}\bigg\}}[/tex]
[tex]{:\implies \quad \bf \therefore \quad x=9\sqrt{3} \: units}[/tex]
Also;
[tex]{:\implies \quad \sf \dfrac{y}{18}=\cos (60^{\circ}) \quad \bigg\{ \because \cos (\theta)=\dfrac{B}{H}\bigg\}}[/tex]
[tex]{:\implies \quad \sf x=\dfrac{18}{2} \quad \bigg\{\because \cos (60^{\circ})=\dfrac{1}{2}\bigg\}}[/tex]
