Answer:

Q'(7,1)

Step-by-step explanation:

The translation

(x,y) >>> (x+7,y-5)

means

"add 7 to x coordinate" and "subtract 5 from y coordinate"

Basically this is a translation of 7 units in x direction (right), and

translation of 5 units in y direction (down)

So Q(0,6) will become Q'(0+7,6-5) = Q'(7,1)

John made a triangle with all three sides the same length, 1 \frac{2}{3} ft. What is the perimeter of the triangle?

UNO [17]

Answer:

5 ft

Step-by-step explanation:

If all sides are of the same length, we can multiply the value of one side by 3, because a triangle has three sides (and the perimeter is all sides added together), to find the perimeter.

$1\frac{2}{3}$ × 3

$1\frac{2}{3}$ can be rewritten as $\frac{5}{3}$ , so:

$\frac{5}{3}$ × $\frac{3}{1}$

$= \frac{15}{3}$

The numerator & denominator share a common factor of 3, so:

5 ft is the final answer/perimeter.

hope this helps!

In preparation for an earnings report, a large retailer wants to estimate p= the proportion of annual sales

mr Goodwill [35]

Using the z-distribution, it is found that the 95% confidence interval for the proportion of sales that occured in December is (0.1648, 0.2948).

<h3>What is a confidence interval of proportions?</h3>

A confidence interval of proportions is given by:

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

In which:

$\pi$ is the sample proportion.

z is the critical value.

n is the sample size.

In this problem, we have a 95% confidence level, hence $\alpha = 0.95$ , z is the value of Z that has a p-value of $\frac{1+0.95}{2} = 0.975$ , so the critical value is z = 1.96.
