Okay i need help finding y x 6 for y = 2/3 please help

1 answer:

4 0

First, you need to substitute y for 2/3:

2/3 • 6

Next, change 6 into a fraction and multiply straight across:

2/3 • 6/1
12/3

Finally, simplify it to its simplest form:

4
Your answer should be 4.
Hopefully that helped!

Answer:

A. 72cm

Step-by-step explanation:

Figure a is a convex pentagon, a convex pentagon is a pentagon that does not have an internal angle greater than

${180}^{0}$

An easier thing to remember is that it does not have an angle pointing inwards like b, none of its angles/edges point toward the shape/inside

A study done by researchers at a university concluded that 70 70% of all student athletes in this country have been subjected t

Alecsey [184]

Answer:

The margin of error is 0.0206 = 2.06 percentage points.

The 95% confidence interval for the proportion of all student athletes in this country have been subjected to some form of hazing is (0.6794, 0.7206).

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:

$n = 1900, \pi = 0.7$

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 margin of error is:

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

$M = 1.96\sqrt{\frac{0.7*0.3}{1900}} = 0.0206$

The margin of error is 0.0206 = 2.06 percentage points.

The lower limit of this interval is:

$\pi - M = 0.7 - 0.0206 = 0.6794$

The upper limit of this interval is:

$\pi + M = 0.7 + 0.0206 = 0.7206$

The 95% confidence interval for the proportion of all student athletes in this country have been subjected to some form of hazing is (0.6794, 0.7206).

1 1/5 - 1/2 in simplest form

Thepotemich [5.8K]

$1 \frac{1}{5} - \frac{1}{2}$ =
$\frac{6}{5} - \frac{1}{2}$ =
$\frac{6 x 2}{5 x 2} = \frac{12}{10}$
$\frac{1x5}{2x5} = \frac{5}{10}$
$\frac{12}{10} - \frac{5}{10}$
$\frac{7}{10}$
