<span>y = 2x + 20. The answer is A. Explanation: Vlad spends a known amount of time on his history homework (20). On top of it, he also spends an unknown amount of time on solving a number of math problems (x). Each problem takes two minutes to solve, so the amount of time that he spends solving math problems is 2*x or 2x. In total (y), Vlad spends 20 + 2x amount of time on his homework. So y = 2x + 20, where y is clearly greater or equal to 20 and x is greater or equal to 0.</span>
To compute for the probability value of P-value, we need to see first as to how is 3 years from the given mean value.
So, for this case we have (3 - 4) = 1 below the standard deviation of 0.8. Thus, the z -score for this would me z < -1/0.8 = -1.25.
Given a z-score of z < -1.25. Using the table chart for the P-values, we have P(z < -1.25) = 0.1056. Meaning there is a 10.56% chance that a CD will last for less than 3 years.
Thus, probability is 10.56%<span>.</span>
Answer:
The answer to your question is 8 h
Step-by-step explanation:
Data
length of the ladder = 200 cm
distance between each rung = 20 cm
rate = 10 cm/h
fifth rung = ?
Process
1.- Calculate the total distance the tide must rise
distance = 20 cm x 4
= 80 cm because the first rung touches the water
2.- Calculate the time
rate = distance / time
-Solve for time
time = distance / rate
-Substitution
time = 80 cm / 10cm/h
-result
time = 8 h
