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 .

A line passes through the point (-8, 3) and has a slope of 3/4. Write an equation in slope-intercept form for this line.
agasfer [191]
General formula to make slope-intercept form
y - y₁ = m(x - x₁)

From the question, we know that
m = 3/4
(x₁,y₁) = (-8,3)

Put the number to the formula
y - y₁ = m(x - x₁)
y - 3 = 3/4(x - (-8))
y - 3 = 3/4(x + 8)
y - 3 = (3/4)x + 6
y = (3/4)x + 9
