Let the number of tie-dyed T-shirts = x
The man sold 4 times as many tie-dyed T-shirts as silk-screened shirts.
So, the number of silk-screened shirts = 4x
He sold 180 shirts altogether
So,
So, the number of tie-dyed shirts = 36
Answer: the probability that a randomly selected tire will have a life of exactly 47,500 miles is 0.067
Step-by-step explanation:
Since the life expectancy of a particular brand of tire is normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = life expectancy of the brand of tire in miles.
µ = mean
σ = standard deviation
From the information given,
µ = 40000 miles
σ = 5000 miles
The probability that a randomly selected tire will have a life of exactly 47,500 miles
P(x = 47500)
For x = 47500,
z = (40000 - 47500)/5000 = - 1.5
Looking at the normal distribution table, the probability corresponding to the z score is 0.067
I know that one is obtuse and acute
So in long numbers or any number the positon determines its in the ones, tenths, hundredths
e.g
658
6 is in the hundredths as it is technically 600
5 is in the tenths as it is 50
8 is the ones as its just 8
Answer:
a. 5
Step-by-step explanation:
arrange
1 2 3 5 5 6 6 6 8 9 9 10 10 11 12 13
median=6+8/2=7
range=13-1=12
difference=12-7=5
