Answer:
Each of those dashes are 5 minute for the small hand
and each of those dashes are 1 minutes for the long hand
Formula for finding the axis of symmetry: x = -b/2a
x^2 - 2x - 15
a = 1; b = -2 (plug these into the formula above)
-(-2)/2(1) = 2/2 = 1
Answer:
The y, in the equation, represents the total distance, in feet, from an ant t minutes after starting out from a location near its home. The 6 represents the the distance of the location where the ant starts traveling. The 3 represents the amount of feet covered in one minute. That's why when you increase the minute by one (experiment!!), the distance away from home increases by three, and that means that the ant is traveling at 3 ft/minute. (lol crazy)
3 = the ant's speed in ft/minute
Answer:
1 and 2
Step-by-step explanation:
square root of 3 is around 1.73
numbers between 1.73 are 2 and 1.
Answer:
99.1 is the 90th percentile of these scores.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 85
Standard Deviation, σ = 11
We are given that the distribution of score is a bell shaped distribution that is a normal distribution.
Formula:
We have to find the value of x such that the probability is 0.90
Calculation the value from standard normal z table, we have,
Putting values, we get,
Thus, 99.1 is the 90th percentile of these scores.
