Answer: the probability that John’s drive to work will take between 36 and 40 minutes is 0.32
Step-by-step explanation:
Since the distribution of driving times is approximately normal, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = driving times.
µ = mean time
σ = standard deviation
From the information given,
µ = 38 minutes
σ = 5 minutes
The probability that John’s drive to work will take between 36 and 40 minutes is expressed as
P(36 ≤ x ≤ 40)
For x = 36,
z = (36 - 38)/5 = - 0.4
Looking at the normal distribution table, the probability corresponding to the z score is 0.34
For x = 40,
z = (40 - 38)/5 = 0.4
Looking at the normal distribution table, the probability corresponding to the z score is 0.66
Therefore,
P(36 ≤ x ≤ 40) = 0.66 - 0.34 = 0.32
Answer:
645 m 86 cm
Step-by-step explanation:
Since 49 cm is greater than 35 cm, we must borrow 100 cm from 800 m, obtaining 799 m 135 cm. Subtracting 154 m 49 cm from that, we get:
645 m 86 cm
No, u cant. Because they are not like terms
Examples :
1 + 2v....cannot add or subtract because they are not like terms
2v + 4v = 6v...u can if they have exactly the same variable
3x^2 + 2x...cant
x^2 + 4x^2...can...= 5x^2
3 + 3 ....can
2 + 5x...cant
now u can multiply and divide one...u just cant add or subtract them
It’s 1.54
Just divide 85/55
Answer:
it would be measured using millimeters
