Answer: p = 0.73
Step-by-step explanation:
Given that,
73% of the audience was under 20 years old :
so, probability (p) = 0.73
n = 146
Mean of the distribution of sample proportion = ?
According to central limit theorem,
np(1-p) ≥ 10
146 × 0.73(0.27) ≥ 10
28.77 ≥ 10
∴ Central limit theorem assumes that the sample distribution of the sample proportion is normally distributed.
Hence, the mean of the distribution of sample proportion:
μ = p = 0.73
Answer:
Amount of peanut butter each student get = 533.34 gram (Approx.)
Step-by-step explanation:
Given:
Amount of peanut butter Mr black has = 32 kg
Total number of students = 60 students
Find:
Amount of peanut butter each student get
Computation:
Amount of peanut butter Mr black has = 32 kg
Amount of peanut butter Mr black has = 32 x 1,000 gram
Amount of peanut butter Mr black has = 32,000 gram
Amount of peanut butter each student get = Amount of peanut butter Mr black has / Total number of students
Amount of peanut butter each student get = 32,000 / 60
Amount of peanut butter each student get = 533.33
Amount of peanut butter each student get = 533.34 gram (Approx.)
Answer:
The car would be worth 1200.
Step-by-step explanation:
Okay, the way to solve this type of question is quite simple,
you would start with the amount is lost per year being $325 a year, then multiply that by the 4 years grandpa waited and then subtract the overall amount lost in worth of the car from the original price and you got your answer.
The math: 2500-(325*4)=1200
So, water decreases by 12 gallons EVERY minute.
<u>How much water will decrease in 60 minutes?</u>
gallons
So, the volume changes by 720 gallons in 60 minutes.
ANSWER: Volume decreases 720 gallons in 60 minutes.
