Answer: 4) 157
Step-by-step explanation:
We know that there is no association between the grade level and the andedness, then we should find that the ratio between left handeds and right handed is the same for both grades.
In 7-th grade we have:
Left handed : 11
Right handed: 72
The ratio is 11/72 = 0.14
Then, the ratio for the 8-th graders must be about the same:
Left handed: 24
Right handed: X
Ratio: 24/X
Let's start with the bigger option, X = 157.
24/157 = 0.15
Ok, we now see that with the bigger option we obtained almost the same ratio (if we use the smaller values for X, we will get a ratio bigger than 0.15, so 0.15 is the better aproximation that we can find to the 0.14 of the 7-th graders)
Then the correct option is 4) 157
The appropriate unit would be pounds/lbs.
Answer:
3
Step-by-step explanation:
3^1=3 divided by 8 will give a remainder of 3
3^2=9 divided by 8 will give a remainder of 1
3^3=27 divided by 8 will give a remainder of 3
3^4=81 divided by 8 will give a remainder of 1
3^5=243 divided by 8 will give a remainder of 3
You will notice that 3^n will give 3 when n is odd number and 1 when n is even number
Since n=99 and 99 is an odd number,
Then the remainder is 3
Respuesta: Uno
La suma de la probabilidad de todos los resultados posibles de un experimento aleatorio debe ser igual a uno.
Porque algunos resultados más ocurren en cada sendero y la suma de todas las probabilidades es 100% o uno.
Espero haber ayudado, buena suerte! :)
