egoroff_w [7]

Answer:

0.12 -1.96*0.013= 0.094

0.12 +1.96*0.013= 0.146

And the best option would be:

0.094 to 0.146

Step-by-step explanation:

For this case we have the following info given:

\hat p=0.12 represent the proportion estimated

SE = 0.013 represent the standard error

Confidence =0.95 represent the confidence level

The confidence interval for the true proportion is given by:

\hat p \pm z_{\alpha/2} SE

And for 95% of confidence the critical value is z_{\alpha/2}= 1.96 and replacing we got:

0.12 -1.96*0.013= 0.094

0.12 +1.96*0.013= 0.146

And the best option would be:

0.094 to 0.146

Find AC for the quadrilateral
Airida [17]

The quadrilateral ABCD is an isosceles trapezoid, and the length of AC for the quadrilateral is 19 feet

<h3>How to determine the length of AC?</h3>

The quadrilateral ABCD is an isosceles trapezoid

This means that:

  • Opposite sides are equal
  • The diagonals are also equal

From the above highlights, we have:

AC = 7ft + 12ft

Evaluate the sum

AC = 19 ft

Hence, the length of AC for the quadrilateral is 19 feet

If A line has a y -intercept of 10 and a slope of 4 . What is its equation in slope -intercept form
chubhunter [2.5K]

Answer:

<h2>          y = 10x + 4</h2>

Step-by-step explanation:

The equation of a line in slope-intercept form is: y = mx + b, where <em>m</em> is a slope and<em> b</em> is y-intercept.

m = 10

b = 4

So, the equation:  y = 10x + 4
