30/2 = 15
15 x 5 = 75
The number is 75.
26. 5x^2+3x-2
The leading coefficient is 5.
28. -5c^2-3c+4
The leading coefficient is -5.
30. t^5+2t+11t-3
The leading coefficient is 1.
Answer:
this mah not be right but i believe it is 7.6
Step-by-step explanation:
if i did it correctly where you just divide 38 by 5 it should be 7.6
Answer:
For this case if we want to conclude that the sample does not come from a normally distributed population we need to satisfy the condition that the sample size would be large enough in order to use the central limit theoream and approximate the sample mean with the following distribution:
![\bar X \sim (\mu, \frac{\sigma}{\sqrt{n}})](https://tex.z-dn.net/?f=%20%5Cbar%20X%20%5Csim%20%28%5Cmu%2C%20%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%29)
For this case the condition required in order to consider a sample size large is that n>30, then the best solution would be:
n>= 30
