No, in order for this to be correct, you'd have to move BOTH decimals in the same direction the same amount of places.<span />

17.43/100=0.1743
174.3/0.01=17430

Divide by 100 equals move 2 decimal place to the left.

Divide by 0.01 equals move 2 decimal place to the right.

Which expression is equivalent to 6(3+0.05)?
Gnesinka [82]

\huge{\boxed{6(3)+6(0.05)}}

The distributive property shows that you need to multiply the 6 separately by each term in the parentheses. This means you multiply 6*3 and 6*0.05, then add them together to get 6*3+6*0.05, or in the terms of your answer choices, \boxed{6(3)+6(0.05)}.

Y = 3x +1; domain = {-1, 0, 1}<br> HELP PLEASE
ser-zykov [4K]

We have to put values of domain to find range

\\ \ast\sf\longmapsto y=3x+1

\\ \ast\sf\longmapsto D_R=[-1,0,1]

\\ \ast\sf\longmapsto y=3(-1)+1=-3+1=-2

\\ \ast\sf\longmapsto y=3(0)+1=0+1=1

\\ \ast\sf\longmapsto y=3(4)+1=12+1=13

Now

\\ \ast\sf\longmapsto R_R=[-2,1,13]

Is the environment a major issue with Americans? To answer that question, a researcher conducts a survey of 1255 randomly select
Furkat [3]

Answer:

The point estimate of this proportion is \pi = 0.5857

The 95% confidence interval to estimate the proportion of Americans who feel that the environment is a major issue with them is (0.5584, 0.6130).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

For this problem, we have that:

n = 1255, \pi = \frac{735}{1255} = 0.5857

The point estimate of this proportion is \pi = 0.5857

95% confidence level

So \alpha = 0.05, z is the value of Z that has a pvalue of 1 - \frac{0.05}{2} = 0.975, so Z = 1.96.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.5857 - 1.96\sqrt{\frac{0.5857*0.4143}{1255}} = 0.5584

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.5857 + 1.96\sqrt{\frac{0.5857*0.4143}{1255}} = 0.6130

The 95% confidence interval to estimate the proportion of Americans who feel that the environment is a major issue with them is (0.5584, 0.6130).
