9. 8x^4 and -3x^4 are both multiplied by x and to the fourth power, so you could combine them and get 5x^4.
10. 3x and 4x are both multiplied by x. you can combine them, and it will leave you with 7x+5.
Hope this helped!

Physicians at a clinic gave what they thought were drugs to 860 patients. Although the doctors later learned that the drugs were

Alexus [3.1K]

Answer:

Z=2.36

P=0.0091

Step-by-step explanation:

The hypothesis is:

π > 0.55 which is the population proportion

The formula to get the test statistic is

Zstat = P-π/√π(1-π)/n

P =507.4/860 = 0.59 (sample proportion )

n =860 (sample size)

π =0.55(population porportion)

Zstat = 0.59-0.55/√0.55(1-0.55)/860

Zstat =2.36

From Z table the probability of Z score of 2.36 is 0.9909

To calculate for P- value will then be

P= 1 - 0.9909

P= 0.0091
