900 is the correct answer
Answer:
E. When the sample size increases, because the standard deviation of the distribution of sample means better estimates the population standard deviation for larger sample sizes.
Step-by-step explanation:
- T distribution is similar to the normal distribution and is seen when the estimates of the variance are based on the degree of freedom and has a relatively more score in its tail and has a greater change of extreme values.
sin(43) × hypotenuse of 19 gives you oppo
= 13
20
This is because
2x+(6x+20)=180
8x+20=180
8x=160
8x/8=160/8
X=20
