Answer:

y=2x+3

Step-by-step explanation:

the equation of a line in slope intercept form is

y=mx+b where m is the slope and b is the y intercept

the graph crosses the y axis at 3, so the y intercept is 3

the line goes up 2 over 1, up 2 over 1, etc so the slope is

$m = \frac{2}{1} = 2$

thus we get y = 2x + 3

In 2015 as part of the General Social Survey, 1289 randomly selected American adults responded to this question:

Radda [10]

Answer:

B (0.312, 0.364)

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 interval $1-\alpha$ , 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:

1289 randomly selected American adults responded to this question. This means that $n = 1289$ .

Of the respondents, 436 replied that America is doing about the right amount. This means that $\pi = \frac{436}{1289} = 0.3382$ .

Determine a 95% confidence interval for the proportion of all the registered voters who will vote for the Republican Party. 

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:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3382 - 1.96\sqrt{\frac{0.3382*0.6618}{1289}} = 0.312$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3382 + 1.96\sqrt{\frac{0.3382*0.6618}{1289}} = 0.364$

The 95% confidence interval is:

B (0.312, 0.364)

Help plz I’ll give brainliest and I’m struggling with this problem

hodyreva [135]

The line is starting from right side and goes thorough left .

Means

Its starts from 1st Quadrant and goes to 3rd Quadrant.(+ve to -ve)
Y is infinite

Hence

The solution is

$\\ \sf\longmapsto (0,\infty]$

Find the GCF of 4g^4 and 34g^3.

USPshnik [31]

Yes, find the prime factors.

4 can be written as 2*2.
g^4 can be written as g*g*g*g.

That is the prime factorization of the first expression.
4g^4 can be written as 2*2*g*g*g*g.

34 can be written as 2*17.
And again we can split up the g business: g^3 is g*g*g.
34g^3 can be written as 2*17*g*g*g.

What do these expressions have in common?
They have a 2 in common,
and three of the g's in common, ya?

Therefore the GCF(4g^4, 34g^3) = 2g^3.
