Answer:
r= -1.8
Step-by-step explanation:
Distribute
-3-18r=14-7
Combine like terms
-3-18r=7
add 3 to both sides
-18r=10
divide by -18
r=-1.8
Answer:
10\pi[/tex]
Step-by-step explanation:
Circunferencia de un círculo = Pi veces diámetro
como el diámetro es igual a la mitad del radio, sabemos que si multiplicamos el radio por dos obtendremos el diámetro del círculo. Por lo tanto, 5 veces 2 = 10. Ahora hacemos 10 veces pi. El cual es 10 pi o 31.4159
Circumference of a circle = Pi times diameter
since the diameter is equal to half the radius, we know that if we multiply the radius by two we will obtain the diameter of the circle. Therefore, 5 times 2 = 10. Now we do 10 times pi. Which is 10 pi or 31.4159
Answer:
C) 3.03
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given sample size 'n' = 50
The Mean of the population (μ) = 62
