Answer:
7.15 hours or 7 hours 9 minutes.
Step-by-step explanation:
Time = distance / average speed.
= 715 / 100
= 7.15 hours.
Answer:
The percent of the pairs that last longer than six months—that is, 180 days is 95.637%
Step-by-step explanation:
Mean = xbar = 208 days
Standard deviation = σ = 14
The standardized score for 180 days is the value minus the mean then divided by the standard deviation.
z = (x - xbar)/σ = (180 - 208)/14 = - 1.71
To determine the percent of boots that last longer than 180 days, we need this probability, P(x > 180) = P(z > (-1.71))
We'll use data from the normal probability table for these probabilities
P(x > 180) = P(z > (-1.71)) = 1 - P(z ≤ (-1.71)) = 1 - 0.04363 = 0.95637 = 95.637%
Answer:
Equation: x=2
Solution = 2
Step-by-step explanation:
add like terms so regular numbers like -5 and -3. Add positive 5 to 3 to get 2
And next the variables -2x+3x= x
Answer: 20
Step-by-step explanation:
Assuming your question is:
Z² - X² - XY X = -2, Y = 3, Z = -4
Substitute values
(-4)² - (-2)² - {(-2)(3)}
{(-4)(-4)} - {(-2)(-2)} - (-6)
(16) - (4) + 6
16 - 4 + 6
20
Answer:
1+5*2 or simplified, 1+10= 11
