Answer:
white 1: black 3
white 2: black 1
white 3: black 2
Step-by-step explanation:
white 1: the denominator for the x values so it becomes 1-2=-1 which becomes -1/3x +1/4
White 2: same case as the first so we add 1+2=3 3/3=1 so that makes it x+1/4
white 3: there is only one x values that has 4 as the denominator therefore that makes the answer 3/4x+1/3
For the second question, the answer is $2060, 5%=0.05, 2,000*0.05=60, 2,000+60=2060. The third question, the answer is $3,307.5, year 1 0.05*3000=150, 3000+150=3150. 3150*0.05=157.5, 3150+157.5=3,307
I can't help you with the first question
Answer: The probability that a randomly selected catfish will weigh between 3 and 5.4 pounds is 0.596
Step-by-step explanation:
Since the weights of catfish are assumed to be normally distributed,
we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = weights of catfish.
µ = mean weight
σ = standard deviation
From the information given,
µ = 3.2 pounds
σ = 0.8 pound
The probability that a randomly selected catfish will weigh between 3 and 5.4 pounds is is expressed as
P(x ≤ 3 ≤ 5.4)
For x = 3
z = (3 - 3.2)/0.8 = - 0.25
Looking at the normal distribution table, the probability corresponding to the z score is 0.401
For x = 5.4
z = (5.4 - 3.2)/0.8 = 2.75
Looking at the normal distribution table, the probability corresponding to the z score is 0.997
Therefore,.
P(x ≤ 3 ≤ 5.4) = 0.997 - 0.401 = 0.596
Yes, BUt where's the fraction
