Answer:
Weak positive
Step-by-step explanation:
From. Visual inspection of the scatter plot, the line of best fit will have a positive slope has values of x tends to increase with a corresponding increase in the value of y.
However, the points are scattered across the plotting area meaning that most of the points will be a bit farther away from the regression line. This means a weak correlation between the x and y variables will be obtained. Since the slope is positive, theb the relationship between the variables based on the scatterplot interpretation is a weak positive correlation.

8 cm
Step-by-step explanation:
The area of the shaded portion is:
[tex]a = \pi \times (( {r1)}^{2} - {(r2}^{2})) [/tex]
A=39π cm^2
r1 is the radius of the large circle
r2=5 cm

You would burn about 200 calories by walking for 1 hour. About how many calories would you burn if you walk for 15 minutes? PLS HELP ME!!!
Answers
Answer:
50
Step-by-step explanation:
So first just sort the times, and the number of calories:
200 calories -> 1hr
x -> 15 mins

Answer: Hope This Helps!
Step-by-step explanation:
Probability that a student is a senior = 0.20. Therefore, the probability that a randomly selected student plays a sport, given that the student is a senior will be 0.25 and option A is the correct choice.
The probability that a student is a senior is equal to 0.20.
We have given that,
At a high school, the probability that a student is a senior is 0.20. The
probability that a student plays a sport is 0.15. The probability that a student IS a senior and plays a sport is 0.05.
What is the probability?
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
Therefore, the probability that a randomly selected student plays a sport, given that the student is a senior will be 0.25, and option A is the correct choice.

Hello! answer: x = 94
Step-by-step explanation:
Triangles add up to 180 degrees so we just add up the two measures we do have so 48 + 38 = 86
Now we subtract that from 180 to find x so
180 - 86 = 94 So 94 is x Hope that helps!

The circumference of a circle is about 33.912 inches. The circle's radius is __ inches.
Use 3.14 for π.
Answers
Answer:
5.4
Step-by-step explanation:
Circumference = 2 x 3.14 x radius
To find this information, you must first divide:
33.912 ÷ 2 = 16.956
Then, divide:
16.956 ÷ 3.14 = 5.4
So then your answer is:
Radius = 5.4

What is the area of a circle that has the diameter of 4?
Answers
Answer:
Hello! answer: 12.56
Step-by-step explanation:
Area for circles is found be doing
radius × radius × pi since we arent given radius we have to figure it out. But what we do know it diameter is just 2 times the radius so to undo that to find our radius we just do 4 ÷ 2 and 4 ÷ 2 = 2 so 2 is our radius now we will square it which is just fancy for multiply is by itself so 2 × 2 = 4
4 × 3.14 = 12.56 So 12.56 is our area! Hope this helps you!

Which statement best describes the association between variable X and variable Y?
Answers
Answer:
weak, negative association
Step-by-step explanation:
If variables have a strong association, the points will form a clear line/curve. Since the graph's points are scattered and fairly chaotic, we can say the association is weak.
Positive associations trend upwards and negative associations tend downwards. This graph seems to overall tend downwards, so we can say the association is negative.
