You would pull out a 4 then 2 “x’s” and then 2 “a’s” because that is all they have in common making the answer 4x^2a^2
A. 10 hours, fro, 6 to noon it’s 6 hours and after 1 p.m. she world 4 more so 10
Answer:
B
Step-by-step explanation:
Distribute 6 to 5/8u and 1 and you get 15/4u + 6. Distribute -6 to -7/4u and -5 and you get 21/2u and 30. The equation will be 15/4u + 6 + 21/2u + 30 and then combine like terms to get 57/4u + 36.
Answer:
98% confidence interval estimate of the proportion of Mississippi mortgages that are delinquent lie between ( 0.0529 , 0.1731 ) or 5.29% to 17.31%
Step-by-step explanation:
Given -
A random sample of 150 mortgages in the state of Mississippi was randomly selected. From this sample, 17 were found to be delinquent on their current payment.
Sample size n = 150
Let x be the no of people delinquent on their current payment
Proportion of sucess
=
=
= 0.113
confidence interval = 99%
= .02
=
= 2.326
98% confidence interval estimate of the proportion of Mississippi mortgages that are delinquent = ![\widehat{p}\pm z_{\frac{\alpha }{2}}\frac{\sqrt{\widehat{p} (1 - \widehat{p})}}{n}](https://tex.z-dn.net/?f=%5Cwidehat%7Bp%7D%5Cpm%20z_%7B%5Cfrac%7B%5Calpha%20%7D%7B2%7D%7D%5Cfrac%7B%5Csqrt%7B%5Cwidehat%7Bp%7D%20%281%20-%20%5Cwidehat%7Bp%7D%29%7D%7D%7Bn%7D)
= ![0.113\pm z_{\frac{.02 }{2}}\frac{\sqrt{0.113 (1 - 0.113)}}{150}](https://tex.z-dn.net/?f=0.113%5Cpm%20z_%7B%5Cfrac%7B.02%20%7D%7B2%7D%7D%5Cfrac%7B%5Csqrt%7B0.113%20%281%20-%200.113%29%7D%7D%7B150%7D)
= ![0.113\pm 2.326\times.02584](https://tex.z-dn.net/?f=0.113%5Cpm%202.326%5Ctimes.02584)
= ![0.113\pm .06010](https://tex.z-dn.net/?f=0.113%5Cpm%20.06010)
= ![(0.113 - .06010) , (0.113 + .06010)](https://tex.z-dn.net/?f=%280.113%20-%20.06010%29%20%2C%20%280.113%20%2B%20.06010%29)
= ( 0.0529 , 0.1731 )
Answer:
17.18400
Step-by-step explanation:
When rounded to the nearest whole number, it's 17.
