Answer:

34 scoops

Step-by-step explanation:

If I were you I would find how many cups nathan can scoop in a minute because not only its the easiest way it's the fastest so what you can do to find that is divide 8.5 by 2 which is 4.25.

since you know how many he can scoop in a minute you can do 8 times 4.25 because their is 8 minutes and 8 times 4.25 is 34

Big chickens: According to a poultry industry news website, the weights of broilers (commercially raised chickens) are approxima

PtichkaEL [24]

Answer: Yes , it is unusual for a boiler to weigh more than 1550 grams .

Step-by-step explanation:

Given : Big chickens: According to a poultry industry news website, the weights of broilers (commercially raised chickens) are approximately normally distributed with mean $(\mu)$ 1358 grams and standard deviation $(\sigma)$ 161 grams.

When the probability that broiler weigh more than 1550 grams < 0.5 , then is unusual otherwise not.

Let x denotes the weight of broiler, then the probability that broiler weigh more than 1550 grams :-

$P(x>1550)=1-P(x\leq1550)\\\\=1-P(\dfrac{x-\mu}{\sigma}\leq\dfrac{1550-1358}{161})\\\\\approx 1-P(z\leq1.19)\ \ [\because\ z=\dfrac{x-\mu}{\sigma}]\\\\=\\\\=1-0.8830\ \ [\text{By using z-table}]\\\\=0.117$

Since 0.117<0.5

Therefore, it is unusual for a boiler to weigh more than 1550 grams .
