Answer:

12 units²

Step-by-step explanation:

area of a triangle is 1/2 of base times height or A=1/2bh so

A=1/2(4)(6) so

A=24(1/2) so

A=12 so

12 units²

Answer:

A = 12

Step-by-step explanation:

$A = \frac{ab}{2}$

$A = \frac{4*6}{2}$

$A = \frac{24}{2}$

$A = 12$

Im assuming you mean the sides of a triangle which the answer would be no as 1+4 does not equal to 25. (A2+b2=c2) for a right triangle

Assuming the population variances are unknown and equal, you wish to test whether the Group 1 population mean is equal to the Gr

Fantom [35]

Answer:

$n_1+n_2-2$

Step-by-step explanation:

If we had 2 independent samples with population variances unknown and equal and we want to compare the population mean between the both groups, the test statistic will be:

$t=\frac{x_1-x_2}{\sqrt{s_p^2(\frac{1}{n_1}+\frac{1}{n_2}) } }$

Where $s_p^2=\frac{(n_1-1)*s_1^2+(n_2-2)*s_2^2}{n_1+n_2-2}$

So, the t-student has $n_1+n_2-2$ degrees of freedom

Where $x_1$ and $x_2$ are the means of the groups, $n_1$ and $n_2$ are the size of the samples and $s_1^2$ and $s_2^2$ are the sample variances.

Find the degree of the polynomial <br> 5mn^4+7mn^2p^5+15np

user100 [1]

Answer:

The degree of this polynomial is "8"

Step-by-step explanation:

Recall that the degree of a polynomial is given by the degree of its leading term. Recall as well that the degree of a term is the maximum number of variables that appear in it.

So, let's examine each of the terms in the given polynomial, and count the number of variables they contain to find their individual degrees. then pick the one with maximum degree, and that its degree would give the actual degree of the entire polynomial.

1) term $5\,m\,n^4$ contains one variable "m" and four variables "n", so a total of five. Then its degree is: 5

2) term $7\,m\,n^2\,p^5$ contains one variable "m", two variables "n", and five variables "p". that is a total of eight variables. Then its degree is: 8
