Divide each term by 3.5 to get x=4.
Answer:
<h2><em><u>ᎪꪀsωꫀᏒ</u></em></h2>
➪x= 3
Step-by-step explanation:
4x-(8-x)-2=9x-20+x-5
=> 4x-8+x-2 = 9x+x-5
=> 5x-10 = 9x-20+x-5
=> -10+5 = 10x-20-5x
=> -5+20 = 5x
=> 15 =5 x
=> 15/5 = x
=> 3 = x
Answer:
157.1
Step-by-step explanation:
We plug in what v is.
12.3(6)=73.8
Then we plug in what w is
11.9(7)=83.3
Lastly, we add the two numbers together to get 157.1
Hope it helped :)
We are given
<span>μ > 1180
</span><span>α = 0.02
</span><span>σ = 201.71
x = </span><span>1198.79
n = 200
The null hypothesis is </span>μ ≤ 1180 while the alternative hypothesis is μ > 1180
The test statistic is 1.32 which means that the confidence internval is 98%. Getting the z-score
z = (x - μ) / σ
z = (1198.79 - 1180) / 201.71
z = 0.093
For a normally distributed population, the z-score of 0.093 has a p-value of
p = 0.46
