There are two buildings bisede each ather that are 47feet and 31 feet high. The buildings are 12 feet apart. What is the distanc
Vsevolod [243]
You use Pythagorean theorem...a^2+b^2=c^2
a=12ft
b=47-31.. height of the triangle
c=distance between two roof tops

(12)^2+(16)^2=c^2
144+256=c^2
400=c^2, take square root of both sides
c=20ft

Mila [183]

Answer:

Answer =b. Since the p-value > α, do not reject the null hypothesis.

Step-by-step explanation:

The null hypothesis is to be rejected if the p- value is less than the given significant level. In this case, the p-value is 0.418 and level of significance α=0.05; the p-value is greater than level of significance therefore we do not reject the null hypothesis.

6. A cookie jar contains 315 M&M's. There are only brown and
Romashka [77]

The system of equations representing the problem is

b+g=315\\8b-g=0

and we have 35 brown M&M's and 280 green M&M's in the cookie jar.

<h3>Formulating the equations</h3>

If we let b represent the number of brown M&M's and g the number of green M&M's, then, from the sentence

"...<em>A cookie jar contains 315 M&M's. There are only brown and green M&M's in the jar</em>..."

we can construct the algebraic equation

b+g=315

Also, from the sentence

"...<em>The number of green M&M's is 8 times that of the brown M&M's</em>..."

we can construct the algebraic equation

g=8b\implies 8b-g=0

overall, we have the system of equations with unknowns b and g

b+g=315\\8b-g=0

<h3>Solving the system of equations</h3>

Adding the two equations, we get

(b + 8b) +(g + (-g))=315+0\\9b=315\\\\\dfrac{9b}{9}=\dfrac{315}{9}\\\\b=35

Substituting this value for b into the relationship g=8b

g=8b\\g=8(35)=280

Therefore, we have 35 brown M&M's and 280 green M&M's
