Answer:
biking at a moderate speed of 12 to 13.9 miles per hour will cause a 155-pound person to burn 298 calories in 30 minutes. At a faster rate of 14 to 15.9 miles per hour, a person of the same weight will burn 372 calories.

Answer:
Yes, his collection will be complete by the time his grandfather visits
Step-by-step explanation:
Here, we want to know if his collection would be complete by the time his grandfather visits.
From the question;
he has collected 13 different quarters in 2.25 months
At the same rate, x different quarters will be collected in 9 months
Thus, mathematically;
x * 2.25 = 13 * 9
x = (13 * 9)/2.25 = 52
Thus, at this rate he would have collected 52 quarters in 9 months.
Since he has only 50 to collect, it means his collection would be complete by the time his grandfather visits
Answer:
The correct option is d
Step-by-step explanation:
From the question we are told that
The population size is
The sample size is
The sample mean is
The standard deviation is
Given that the confidence level is 95% then the level of significance can be calculated as
Next we obtain the critical value of from z-table , the value is
The reason we are obtaining critical value of
instead of is because
represents the area under the normal curve where the confidence level interval (
) did not cover which include both the left and right tail while
is just the area of one tail which what we required to calculate the margin of error
.
NOTE: We can also obtain the value using critical value calculator (math dot armstrong dot edu)
Generally the margin of error is mathematically represented as
substituting values
The 95% confidence level interval is mathematically represented as
substituting values
3/50, or 6%. You have 3 chances to win out of 50 numbers, and 3 divided by 50 is .06, which translates to 6%.
