Do you av options, Because i need to see the folding method
Answer:
6.5%
Step-by-step explanation:
I = prt
5616 = 7200 × r × 12
r = 5616/(7200 × 12)
r = 0.065
r = 6.5%
The 68-95-99.7 rule tells us 68% of the probability is between -1 standard deviation and +1 standard deviation from the mean. So we expect 75% corresponds to slightly more than 1 standard deviation.
Usually the unit normal tables don't report the area between -σ and σ but instead a cumulative probability, the area between -∞ and σ. 75% corresponds to 37.5% in each half so a cumulative probability of 50%+37.5%=87.5%. We look that up in the normal table and get σ=1.15.
So we expect 75% of normally distributed data to fall within μ-1.15σ and μ+1.15σ
That's 288.6 - 1.15(21.2) to 288.6 + 1.15(21.2)
Answer: 264.22 to 312.98
hi
here is the method :
you take Value 1 and Value 2
And you do : ( Value 2 - Value 1) / (Value 1 ) * 100
Here we have : Value 1 = 352 000
Value 2 = 337 920
So now we apply :
( 337 920 - 352 000 ) / ( 352 000) * 100 = -4
Population decreased by by 4 %
You can also make :
352 000 * X = 337 920
X = 337 920 / 352 000
X = 0.96
if the multiplier is 0.96 , it's mean that we lost 1 -0.96 = 0.04
which mean - 4%
₇P₅ is a permutation. you can find this setting in the statistics menu of your scientific calculator (i think).
If you don't have a scientific calculator, you can use the following formula:
nPr = 
₇P₅ = 
= 
= 
= 7 * 6 * 5 * 4 * 3
= 2520
