Answer:
The Third choice- Δpqr is an equilateral triangle
Explanation:
If you put it on the graph and make the triangle on the graph. You get your answer.
Answer:
the solution to the inequality is 10511
Explanation:
Explanation:
5x=3
x=<u>3</u>
<u> </u><u> </u><u> </u><u> </u>5
3y=<u>5</u>
<u> </u>y=<u>5</u><u> </u>
<u> </u><u> </u><u> </u><u> </u><u> </u>3
now,
=x/y
=3/5÷5/3
=<u> </u><u>9</u>
<u> </u><u> </u><u> </u>5

Using the t-distribution, as we have the standard deviation for the sample, it is found that the 95% confidence interval for the number of units students in their college are enrolled in is (11.7, 12.7).
<h3>What is a t-distribution confidence interval?</h3>
The confidence interval is:

In which:
is the sample mean.
- s is the standard deviation for the sample.
The critical value, using a t-distribution calculator, for a two-tailed <em>95% confidence interval</em>, with 49 - 1 = <em>48 df</em>, is t = 2.0106.
Hence:


The 95% confidence interval for the number of units students in their college are enrolled in is (11.7, 12.7).
