3:00 p.m.

Answers

If you would like to know what will the time be 3 hours and 15 minutes later, you can calculate this using the following steps:

11:45 a.m. + 3 hours and 15 minutes = 12:00 p.m. + 3 hours = 15:00 p.m. = 3:00 p.m.

The correct result would be 3:00 p.m.

Answer:

300 pm

Solve by the multiplication of equality 5/49*x = 20/7

Answers

5/49(x) = 20/7 
5x/49 = 20/7
5x/49 × 49  = 20/7 × 49
5x  = 140
5x / 5  = 140 / 5
x = 28

Newton's second law says force (f) is equal to mass (m) times acceration (a). A scientist wants to calculate the force of an object where the acceleration of gravity (g) is 9.8 m/s2. Use the function to calculate the force for an object with a mass (m) of 0.29 kilograms.

Answers

Force = mass x accerelation
= 0.29 x 9.8
= 2.842 N

Answer:

2.842 N


Step-by-step explanation:

Newton's second law is given by the equation  F=ma

Where,

  • F is the force in Newtons
  • m is the mass in kilograms (kg)
  • a is acceleration given in meters per second squared

Given in the problem,

m = 0.29 kg, and

a = 9.8 meters per second squared


Substituting into the formula gives us F:

F=ma\nF=(0.29)(9.8)\nF=2.842  Newtons (N)

Weston completed a hypothesis test and found that he could not reject the null hypothesis. Which of the following is a valid reason for his conclusion? A.The z-statistic is less than 0.

B.The z-statistic lies in the critical region.

C.The z-statistic is greater than 0.

D.The z-statistic lies outside the critical region.

Answers

The answer to the statistical question presented above would be letter B. The z-statistic lies in the critical region. If Weston completed a hypothesis test and found that he could not reject the null hypothesis, then it is valid to say that the z-statistic lies in the critical region.

Answer:

The z-statistic lies in the critical region.
