Answer:

Playing violin causes students to get better grades.  

is a reasonable conclusion

Step-by-step explanation:

Given that the correlation coefficient for practicing violin and getting better grades in a group of people is 0.8.

If practicing violin time is taken as x and getting better grades is taken as y then we are given that x and y are positive strong correlated.  Strong because correlation coefficient is >0.5

Hence the given conclusion is reasonable.

Playing violin causes students to get better grades.

I think the correct answer from the choices listed above is the second option. The conclusion saying playing violin causes students to get better grades is a reasonable conclusion. This is because the correlation coefficient is above 0.5, so that implies causation. Hope this answers the question.

What is the length of an arc cut off by an angle of 1.5 radians on a circle of radius 8 inches?
Natali [406]

To solve this problem, we should first recall that the circumference is the measure of the total arc enclosing the circle. The formula for circumference is:

Circumference = 2 π r

where r is the radius of the circle

 

Now since we are only looking for a fraction of the arc, not the total arc, therefore this simply means we are finding for a portion of the circumference. Now we use the formula:

Arc length = (θ / 360) * 2 π r

Where θ/360 represents how much of the fraction is the arc

 

Convert angle to degrees: θ = 1.5 rad (180° / π rad) = (270/π)°

 

Therefore the arc length is:

Arc length = (270/π / 360) * 2 π (8 inches)

Arc length = 12 inches

Now, 50 + 4 = 54!

Hope so now i get it correct!

The Pick 4 games in many state lotteries announce a four‑digit winning number each day. Each of the 10,000 possible numbers 0000
Finger [1]

Answer:

Step-by-step explanation:

Given that the Pick 4 games in many state lotteries announce a four‑digit winning number each day. Each of the 10,000 possible numbers 0000 to 9999 has the same chance of winning. You win if your choice matches the winning digits. Suppose your chosen number is 3079 .

a) The probability that the winning number matches your number exactly

= 1 out of 10000 = 0.0001

b) the probability that the winning number has the same digits as your number in any order

This includes 0379, 0397, 0739, 0793, 0937, 0397 i.e. starting from 0 there are 6 = 3! ways

Or 3079 can be arranged in 4! ways = 24

Favorable outcomes = 24

Prob of winning = 24/10000 = 0.00024

=0.0002
