Answer:

x = 3, x = 15, x = 12, x = 1

Hope this helps :)

Step-by-step explanation:

1.) 4x - 1 = 2x + 5

+1 +1

4x = 2x + 6

-2x -2x

2x = 6

x = 3

2.) 3x - 5 = 2x + 10

+5 +5

3x = 2x + 15

-2x -2x

x = 15

3.) 4x + 2 + 30 = 8 + 6x

4x + 32 = 8 + 6x

-8 -8

4x + 24 = 6x

-4x -4x

24 = 2x

x = 12

4.) 4( x - 1) + 5 = 2x + 3

4x -4 + 5 = 2x + 3

4x + 1 = 2x + 3

-1 -1

4x = 2x + 2

-2x -2x

2x = 2

x = 1

The town of Hayward (CA) has about 50,000 registered voters. A political research firm takes a simple random sample of 500 of th

timama [110]

Answer: (0.076, 0.140)

Step-by-step explanation:

Confidence interval for population proportion (p) is given by :-

$\hat{p}\pm z_{\alpha/2}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

, where $\hat{p}$ = sample proportion.

n= sample size.

$\alpha$ = significance level .

$z_{\alpha/2}$ = critical z-value (Two tailed)

As per given , we have

sample size : n= 500

The number of Independents.: x= 54

Sample proportion of Independents $\hat{p}=\dfrac{x}{n}=\dfrac{54}{500}=0.108$

Significance level 98% confidence level : $\alpha=1-0.98=0.02$

By using z-table , Critical value : $z_{\alpha/2}=z_{0.01}=2.33$

The 98% confidence interval for the true percentage of Independents among Haywards 50,000 registered voters will be :-

$0.108\pm (2.33)\sqrt{\dfrac{0.108(1-0.108)}{500}}\\\\=0.108\pm2.33\times0.013880634\\\\=0.108\pm0.03234187722\\\\\approx0.108\pm0.032=(0.108-0.032,\ 0.108+0.032)=(0.076,\ 0.140)$

Hence, the 98% confidence interval for the true percentage of Independents among Haywards 50,000 registered voters.= (0.076, 0.140)
