Answer:
=21+11x
Step-by-step explanation:
<u>Ans(a):</u>
Given that total distance = 1158 km
Estimated time of drive = 12
now question says to distance that can be driven in 1 hour.
Indirectly it is asking for his speed.
So we can use formula of speed
km per hour.
Hence he will drive approx 96.5 km in 1 hour.
<u>Ans(b):</u>
Actual driven distance = 484 km
Actual time taken = 5 hours
Then actual speed
km per hour
Comparing speeds in both parts, we see that actual speed 96.8 km/hour is more than the expected speed 96.5 km/hour.
Hence he will reach at his destination on schedule or before the expected time.
Answer:
16% of the individuals from this population will have LDL levels are 1 or more standard deviations above the mean.
Step-by-step explanation:
The 68-95-99.7 rule states that:
68% of the measures of a normally distributed sample are within 1 standard deviation of the mean. 34% of them above, 34% of them below.
What percentage of individuals from this population will have LDL levels 1 or more standard deviations above the mean?
Of the 50% of the measures that are above the mean, 34% are within 1 standard deviation. So 50-34 = 16% are 1 or more standard deviations above the mean.
