Answer:
B
Step-by-step explanation:
A rational number is one that can be written in the form p/q, where p and q are whole numbers. However, cannot be simplified further. It is impossible to write it in the form of p/q, so it's not A.
An irrational number is just the opposite of a rational one: it can't be written in the form p/q. Since isn't rational, it's irrational, so B is correct.
An integer is a number without any decimal values. is approximately 17.889. Clearly, this is a decimal, so it's not C.
D is wrong because we know is irrational.
Hope this helps!
Answer:
0.4967<p<0.6033
Not effective
Step-by-step explanation:
given that a clinical trial tests a method designed to increase the probability of conceiving a girl.
In the study 580 babies were born, and 319 of them were girls
Sample proportion p=
Standard error of proportion p =
Margin of error for 99%= Z critical * std error=
(Since sample size is large Z value is used)
Confidence interval 99%
=
0.4967<p<0.6033
This method appears to be not effective as the confidence interval 99% contains 0.50 indicating probability for girls is still 0.50
Answer:
Step-by-step explanation:
One
The input is the top line. B is the output when multiplied by 4
B = 4A
Input A 12 15 47 34
Output B 48 60 188 136
Rule: 12 * 4 = 48; 15*4 = 60
Check the other two.
Two
B = A/2
Input A 44 56 18 26 20
Output B 22 28 9 13 10
Rule: 44/2 = 22; 56/2 = 28
Check the others.
