Which of the following correlation coefficients would represent the weakest correlation?

Dima020 [189]

<h3>Answer: C) 0.02</h3>

====================================================

Explanation:

Any r values close to -1 or +1 represent strong correlation. Specifically, anything close to r = -1 is strong negative correlation, while anything close to r = 1 is strong positive correlation.

As you move closer to r = 0, the correlation weakens. The value r = 0.02 in choice C is the closest to r = 0, so this correlation is the weakest among the group of other r values.

In the given the figure above, m∠BAC = 64° and m∠CBA = 56°. Part I: Find the m∠DEC. Part II: Explain the steps you took to arriv

Doss [256]

Answer:

56, see step-by-step.

Step-by-step explanation:

1. AB is parallel to CD. 1. Given

BC is parallel to DE.

m<BAC=64 and m<CBA =56

2. m<BAC + m<CBA + m<BCA =180 2. The angles in a triangle add up to 180

3. 64+ 56+ m<BCA=180 3. Substitution property of equality.

4. 120 + m<BCA=180 4. Addition property of equality.

5. m<BCA=60 5. Subtraction property of equality.

6. BC is a transversal that cuts through parallel lines AB and CD.

6. Def. of transversal.

7. m<CBA = m<BCD 7. If two parallel lines are cut by a transversal, then alternate interior angles are congruent.

8. m<BCA+m>BCD+m<DCE= 180. 8. Angle addition postulate

9. 60+56+m<DCE=180. 9.substitution.

10. 116 + m<DCE =180 10. Addition property of equality.

11. M<DCE =64 11. Subtraction property of equality.

12. DC is a transversal that cuts through parallel line BC and DE.

12. Def of transversal.

13. m<EDC= m<BCD 13. If two parallel lines are cut by a transversal, then alternate interior angles are congruent.

14. m<EDC= 60. 14. Substitution property of equality.

15. m<EDC+m<DCE+m<Dec=180. 15. Angle addition postulate

16. 56+64+m<dec = 180.16 Substitution property of equality.

17. 120+ m<dec = 180. Addition property of equality.

18. m<dec = 60 18. Subtraction property of equality.

For each function below, determine whether or not the function is injective and whether or not the function is surjective. Be su

olga55 [171]

Answer:

The function is neither injective nor surjective

Step-by-step explanation:

f: P({1,2,3}) -> N is given by f(A) = |A|

where P(S) denotes the power set of a set S and |A| the number of elements of A

$P(\left \{ 1,2,3 \right \})=\left \{ \varnothing ,\left \{ 1 \right \},\left \{ 2 \right \},\left \{ 3 \right \},\left \{ 1,2 \right \},\left \{ 1,3 \right \},\left \{ 2,3 \right \},\left \{ 1,2,3 \right \} \right \}$

$f(\varnothing )=0$

$f(\left \{ 1 \right \})=f(\left \{ 2 \right \})=f(\left \{ 3 \right \})=1$

$f(\left \{ 1,2 \right \})=f(\left \{ 1,3 \right \})=f(\left \{ 2,3 \right \})=2$

$f(\left \{ 1,2,3 \right \})=3$

The function is not injective, for

$P(\left \{ 1 \right \})=P(\left \{ 2 \right \})$

but

$\left \{ 1 \right \}\neq \left \{ 2 \right \}$

The function is not surjective either, because 5 is a natural number which is not the image of any element A under f, i.e., there is no element in A in P({1,2,3}) such that f(A)=5

We don't really know because we don't know how many people who don't like baseball play. Let's assume none of them.

Of the 500 people, (48/120) × 500 people like baseball, and 3/5 of those play.

(3/5)(48/120)(500)=120 play baseball.

Answer: 120
