5000+300+70 expanded form
5370 number form
Answer:
B. 6:00
Step-by-step explanation:
There are 60 minutes in one hour.
To calculate 40 minutes after 4:40, separate 40 minutes into two lots of 20 minutes.
⇒ 4:40 + 20 minutes = 5:00
⇒ 5:00 + 20 minutes = 5:20
Therefore, 40 minutes after 4:40 is 5:20
To calculate the time that 5:20 is 40 minutes before, add 40 minutes to 5:20
⇒ 5:20 + 40 minutes = 6:00
Therefore, the solution is option B. 6:00

Answer:
The greater the sample size the better is the estimation. A large sample leads to a more accurate result.
Step-by-step explanation:
Consider the table representing the number of heads and tails for all the number of tosses:
Number of tosses n (HEADS) n (TAILS) Ratio
10 3 7 3 : 7
30 14 16 7 : 8
100 60 40 3 : 2
Compute probability of heads for the tosses as follows:

The probability of heads in case of 10 tosses of a coin is -0.20 away from 50/50.

The probability of heads in case of 30 tosses of a coin is -0.033 away from 50/50.

The probability of heads in case of 100 tosses of a coin is 0.10 away from 50/50.
As it can be seen from the above explanation, that as the sample size is increasing the distance between the expected and observed proportion is decreasing.
This happens because, the greater the sample size the better is the estimation. A large sample leads to a more accurate result.
The solutions of the equations for x are given as follows:
a. x = 36.
b. x = 15.
<h3>What is the solution for item a?</h3>
The equation for item a is given by:
x/3 - 5 = 7
Isolating x, we have that:
x/3 = 12
x = 3 x 12
x = 36.
<h3>What is the solution for item b?</h3>
The equation for item b is given by:
x/2 - 5 = 2.5
Isolating x, we have that:
x/2 = 7.5
x = 7.5 x 2
x = 15.
Hence the solutions are:
a. x = 36.
b. x = 15.
