A term is a single number or variable, in this case, the number 2.

The sum in this equation would be 4x + 2.

The product is the result of a multiplication, in this equation, the result of 5(4x + 2).

The factors are the digits that are being multiplied, in this case 5 & 4x + 2

The quotient is the result of a division, in this case, the result of (4x + 2) / 7y.

The coefficient is a number that is being multiplied by a variable, in this case, 4 & y.


Hope it helped,

Find the area of the polygon
Oksana_A [137]

Answer:

Area of a regular polygon formulas

Step-by-step explanation:

area = n * a * ri / 2 , having ri - incircle radius (it's also an apothem - a line segment from the center to the midpoint of one of its sides)

area = perimeter * ri / 2 , given ri and polygon perimeter.

area = n * (ri)² * tan(π/n) , given ri.

Consider the following data to determine whether there is a significant difference between the values of Group 1 and Group 2. Le
cestrela7 [59]

Using the t-distribution, it is found that since the p-value of the test is 0.72 > 0.05, there is not significant difference between the values of each group.

At the null hypothesis, we <u>test if the groups have the same values</u>, that is, the subtraction of their means is 0:

H_0: \mu_2 - \mu_1 = 0

At the alternative hypothesis, we <u>test if the groups have different values</u>, that is, the subtraction of their means is different of 0:

H_1: \mu_2 - \mu_1 \neq 0

First, we have to find the mean and the standard deviation for both samples, hence, using a calculator:

\mu_1 = 18.75, \sigma_1 = 6.2507, \mu_2 = 19.75, \sigma_2 = 4.2678

The standard errors are:

s_1 = \frac{\sigma_1}{\sqrt{n_1}} = \frac{6.2507}{\sqrt{8}} = 2.21

s_2 = \frac{\sigma_2}{\sqrt{n_2}} = \frac{4.2678}{\sqrt{8}} = 1.5089

For the distribution of differences, we have that:

\overline{x} = \mu_2 - \mu_1 = 19.75 - 18.75 = 1

s = \sqrt{s_1^2 + s_2^2} = \sqrt{2.21^2 + 1.5089^2} = 2.676

We have the <u>standard deviation for the samples</u>, hence, the t-distribution is used. The test statistic is given by:

t = \frac{\overline{x} - \mu}{s}

In which \mu is the value tested at the null hypothesis, which is 0 for this problem. Hence, the value of the test statistic is:

t = \frac{\overline{x} - \mu}{s}

t = \frac{1 - 0}{2.676}

t = 0.37

To find the p-value, we have a <u>two-tailed test</u>, as we test if the means are different from a value, with <u>t = 0.37</u> and 8 + 8 - 2 = <u>14 df</u>.

Using a t-distribution calculator, this p-value is of 0.72.

Since the p-value of the test is 0.72 > 0.05, there is not significant difference between the values of each group.

Find the angle marked with the ? mark
Yuri [45]

Answer:

53 degrees

Step-by-step explanation:

Angle N = angle E

because angle made by joining end points of same chord on circumference are always equal.

so angle E = 37

Angle D = 90 ( because angle made by diameter on circumference is 90 degrees)

Now in Triangle DEC. Sum if all the angles of triangle us 180

Angle D + angle E + ? = 180

37 + 90 + ? = 180

127 + ? = 180

? = 180 - 127

? = 53 degrees
