2 to 60 is 58 -48 is 10
so you have think what sort of maths skills are used like it could n+58 -48 then square or something ,but check what the differences are between the numbers.
hope it helped.
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
Answer:
30 short cakes
Step-by-step explanation:
25ml = 10ml + 10ml +5ml
each 10ml of milk can make us 12 short cakes
we can two 10ml of milk (20ml) which can make us 24 short cakes.
but we have 25 ml of milk so how much does 5ml of milk give us if 10ml of milk gives us 12 short cakes ?
5ml makes us 6 short cakes. 24 short cakes plus 6 short cakes =30 shortcakes.
25ml of milk =10ml(12shortcakes)+ 10ml(12 shortcakes)+5ml(6 shortcakes)
The mean is the average.
Let A = mean
A = (18 + 14 + 9 + 6 + 3)/5
A = 50/5
A = 10
