Got it!
There are 2π radians in a complete circle.
Now, let's calculate the circumference.
5/2π = 60/circumference.
Next, solve for the circumference.
By multiplying both sides by 2π, we have: 5 * circumference = 120π.
Now divide both sides by 5, and we find: circumference = 24π.
Using the formula c = 2πr,
we set 24π = 2πr.
Dividing both sides by 2π gives us r = 12. Thus, the radius measures 12cm.
90kg of sand was divided into 3 bags, constituting a total of 2+3+7=12 sections.
90kg/12=7.5kg
The smaller bag comprises 2 sections, hence it weighs 7.5kg*2=15kg
The medium-sized bag consists of 3 sections, leading to a total weight of 7.5kg*3=22.5kg
The larger bag encompasses 7 sections, resulting in a weight of 7.5kg*7=52.5kg
Thus, the ratio 2:3:7 translates to 15kg:22.5kg:52.5kg
Verifying, 15kg+22.5kg+52.5kg equals 90kg
Respuesta: 1.8 bolsas
Explicación paso a paso:
A partir de la pregunta, considerando que Robby tiene 4 4/9 bolsas de comida para mascotas, 2/5 eran comida para perros.
2/5 de 4 4/9 = comida para perros.
Convierte 4 4/9 a fracción impropia= 40/9.
2/5 de 40/9 implica 2/5 × 40/9.
= 16/9.
= 1.78 o 1.8.

Answer:
(A) Approximately normal with a mean of $206,274 and a standard deviation of $3,788.
Step-by-step explanation:
The Central Limit Theorem asserts that for a random variable X that follows a normal distribution with a mean of
and a standard deviation of
, the sampling distribution of sample means, when drawn with size n, can be estimated as a normal distribution with a mean of
and a standard deviation of
.
Even if the variable is skewed, as long as n is no less than 30, the Central Limit Theorem still holds.
Population:
Right skewed
Mean $206,274
Standard deviation $37,881.
Sample:
<pbased on="" the="" central="" limit="" theorem="" it="" can="" be="" approximated="" to="" normal.="">
Mean $206,274
Standard deviation 
So the correct answer is:
(A) Approximately normal with a mean of $206,274 and a standard deviation of $3,788.
