Which statement is true? 5 6 8 27 을 ll < - 3 8 4 8 6 6

Neko [114]

Fractions

We are going to be checking each statement in order to find which of them are correct:

We can see that in the drawing 3/8 is smaller than 5/6. Then this statement is false.

We can see that in the drawing 5/8 is smaller than 4/6. Then this statement is false.

<h2>2/6 = 3/8 - 2/6 is equal to 3/8</h2>

We can see that in the drawing 3/8 is bigger than 2/6. Then this statement is false.

<h2>3/6 = 4/8 - 3/6 is equal to 4/8</h2>

We can see that in the drawing 4/8 is equal to 3/6. Then this statement is true.

<h2>Answer: 3/6 = 4/8</h2>

Partition segment MR into a 2:1 ratio with point L. What are the coordinates of L?

lisabon 2012 [21]

Answer:

<em>The coordinates of L are (4,5)</em>

Step-by-step explanation:

<u>Partition</u>

Given the points M(-2,-3) R(7,9), we must find a point L(x,y) such that the distance from M to L is double the distance from L to R. This means:

$\overline{ML}=2.\overline{LR}$

We'll apply that relation on both axes separately:

$x_M-x=2(x-x_R)$

$-2-x=2(x-7)$

Operating:

$-2-x=2x-14$

Joining like terms:

$3x=12$

Solving:

$x= 12/3=4$

Now for the y-axis:

$y_M-y=2(y-y_R)$

$-3-y=2(y-9)$

Operating

$-3-y=2y-18$

Joining like terms:

$3y=15$

Solving

$y=15/3=5$

Thus the coordinates of L are (4,5)

estimate the number of first-year students at an assembly meeting. He surveys 60 students and finds that 24 of them are first-ye

bogdanovich [222]

Answer:

The values needed to calculate a confidence interval at the 95% confidence level are $z = 1.96, n = 60, \pi = \frac{24}{60} = 0.4$

The 95% confidence interval for the proportion of first-year students at an assembly meeting is (0.276, 0.524).

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:

$n = 60, \pi = \frac{24}{60} = 0.4$

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 values needed to calculate a confidence interval at the 95% confidence level are $z = 1.96, n = 60, \pi = \frac{24}{60} = 0.4$

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.4 - 1.96\sqrt{\frac{0.4*0.6}{60}} = 0.276$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.4 + 1.96\sqrt{\frac{0.4*0.6}{60}} = 0.524$

The 95% confidence interval for the proportion of first-year students at an assembly meeting is (0.276, 0.524).
