Given that the logarithm of 7623 is 3.8821, what is the logarithm for each answer listed below? a. 0.8821 b. 7.8821 c. 1.8821

1 answer:

3 0

Hello :
calculate : x , y , z :
1) logx = 0.8821
2) logy = 7.8821
3) logz = 1.8821
note : loga = b equiv : a= 10^b ... a <span>> 0
so :
x = 10^(0.8821) = 7.62 y = 10^(7.8821) = 76225450.54
z = 10^(1.8821) = 76.22</span>

Answer: 0.0125

Step-by-step explanation:

Given : A survey by the Pew Research Center asked a random sample of 2142 U.S. adults and a random sample of 1055 college presidents how they would "rate the job the higher education system is doing in providing value for the money.

5% the U.S. adults and 17% of the college presidents provided a rating of "Excellent."

i.e. $n_1=2142,\ n_2=1055$

$p_1=0.05$ , $p_2=0.17$

The standard error of the difference in sample proportions :-

$\sqrt{\dfrac{p_1(1-p_1)}{n_1}+\dfrac{p_2(1-p_2)}{n_2}}$

$=\sqrt{\dfrac{0.05(1-0.05)}{2142}+\dfrac{0.17(1-0.17)}{1055}}\\\\=0.0124867775151\approx0.0125$

Hence, the standard error of the difference in sample proportion = 0.0125
