Hello,

Let's assume a,b,c the 3 sides of the triangle.

a=9
b=10
c=24-a-b=5

p= \dfrac{a+b+c}{2} =12\\

S= \sqrt{p(p-a)(p-b)(p-c)} = \sqrt{12*3*2*7} = \sqrt{504} =22,4499...\approx{22}

HELP PLS WITH PYTHAGOREAN THEOREM
Darina [25.2K]

Answer:

100 ft

Step-by-step explanation:

We need to find the diagonal ( or hypotenuse)

We can use the Pythagorean theorem

a^2+b^2 = c^2  where a and b are the legs and c is the hypotenuse

80^2 + 60^2 = c^2

6400+3600 = c^2

10000 = c^2

Taking the square root of each side

sqrt(10000) = sqrt(c^2)

100 = c

what are the hypotheseses for the global test of the multiple regression model with three independent variables
harkovskaia [24]

Answer:

Step-by-step explanation:

For a multiple regression model with 3 independent variables,

Y = A0 + A1X1 + A2X2 + A3X3

The hypotheses for the global test of a multiple regression model are:

Null hypothesis H0: there is no relationship between the slopes - A1, A2, A3 - and the outcome. A1, A2, A3 = 0; R^2 = 0

Alternative hypothesis H1: there is a relationship between at least one of the slopes and the outcome. One of A1, A2, A3 is not equal to zero. R^2 is not equal to zero.
