Answer:
Step-by-step explanation: I think you skip count by 50s or something like that. So, it has to be 64.
Answer:
Step-by-step explanation:
Let x be the random variable. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = standard deviation
From the information given,
µ = 474
σ = 32
x = 514
The probability of being below 514 is expressed as P(x < 514)
For x = 514,
z = (514 - 474)/32 = 1.25
Looking at the normal distribution table, the probability value corresponding to area below the z score is 0.89
Therefore,
P(x < 514) = 0.89
Answer:
6.88
Step-by-step explanation:
sin60=p/h
sq.root3/2=x/8
0.86*8=x
x=6.88
6+5+10= 22 (ignore this i have to have 20 characters to submit this answer )
