PLEASE HELP THANK YOU SO MUCH Consider the statement.

Mathematics
1 answer:
Sliva [168]4 years ago
7 0

Answer: False.

Step-by-step explanation:

The statement is:

"The sum of two irrational numbers is always an irrational number."

We know that √2 is an irrational number.

Then the opposite number, (-1)*√2 is also an irrational number.

Then we can sum two irrational numbers like:

√2 + (-√2) = 0

and 0 is a rational number.

Then we have found a counter-example, which means that the statement is false.

Write these lengths in order of size, starting with the smallest. 0.043 km 433cm 4340mm 4.3m
Ahat [919]

The order of length measurement starting with the smallest is 4.3 m, 433 cm, 4340 mm, and 0.043 km.

To compare the given measurements of length, they should have similar units. In this case, we can convert each length measurement to meter. The following conversion of different units to meter is listed below:

  • 1 km = 1000 m
  • 1 cm = 0.01 m or 100 cm = 1 m
  • 1 mm = 0.001 m or 1000 mm = 1 m

Conversion of units to m:

  • 0.043 km * (1000 m/km)= 43 m
  • 433 cm * (0.01 m/cm) = 4.33 m
  • 4340 mm * (0.001 m/mm)= 4.34 m
  • 4.3 m

Lengths in order of size starting with the smallest:

  1. 4..3 m
  2. 433 cm or 4.33 m
  3. 4340 mm or 4.34 m
  4. 0.043 km or 43 m

Since an instant replay system for tennis was introduced a a major tournament, men challenged 1390 referee calls, with the resul
alexandr402 [8]

Answer:

H0: μm − μw = 0

against the claim

Ha: μm − μw ≠ 0

Since the calculated value of z= 0.6177 does not lie in the critical region the null hypothesis is accepted that men and women have equal success in challenging calls.

Step-by-step explanation:

1) Let the null and alternate hypothesis be

H0: μm − μw = 0

against the claim

Ha: μm − μw ≠ 0

2) The significance level is set at 0.05

3) The critical region is z > + 1.96 and z< -1.96

4) The test statistic

Z= p1-p2/ sqrt [pcqc( 1/n1+ 1/n2)]

Here p1= 411/ 1390= 0.2956     and    p2= 213/753=0.2829

pc = 411+ 213/1390+753

pc=624/2143

pc= 0.2912

qc= 1-pc= 1-0.2912=0.7088

5) Calculations

Z= p1-p2/ sqrt [pcqc( 1/n1+ 1/n2)]

z= 0.2956-0.2829/√ 0.2912*0.7088( 1/1390+ 1/753)

z= 0.0127/ √0.2064 (0.00204)

z= 0.0127/0.02056

z= 0.6177

6) Conclusion

Since the calculated value of z= 0.6177 does not lie in the critical region the null hypothesis is accepted that men and women have equal success in challenging calls.
