Answer:
2.700 × 10-7
Step-by-step explanation:
Answer: 2.7*10^-4
step by step explanation:
1. Make the number a new number between 1 and 10
More Icon
Move the decimal point to make 0.00027 a new number between 1 and 10. Because our original number is less than one, we move the decimal point to the right. Drop any zeroes in front of the number. Keep track of how many times we move the decimal point.
0.00027 -> 2.7
Our new number is 2.7. We moved the decimal point 4 times.
2. Define the power of 10
More Icon
Because our original number was less than one, the exponent defining the power of 10 is negative. Remember, we moved the decimal point 4 times, so the exponent is negative 4
10^(-4)
3. Final result
2.7*10^(-4)
b) What is the minimum and maximum number of people that are on neither of these teams?
Let x = number of individuals both in basketball and football
c) Draw a Venn diagram to illustrate this
Answer:
a) min: 0; max: 21
b) min: 34; max: 55
Step-by-step explanation:
In the attached Venn diagrams (part c), the overlap of the two circles represents the number on both teams.
a) In the top diagram, there is no overlap, so the number on both teams is 0.
In the bottom diagram, there is complete overlap between the teams, so the maximum number that play both sports is 21 (the minimum team size of the two teams).
both teams minimum: 0; maximum: 21
__
b) The number on neither team is the number outside both circles. The minimum number will correspond to the case where there is no overlap between teams. In that case, there are 66 team players, so 34 people who are on neither team.
The maximum case is that where the teams completely overlap, so the number not on either team will be those not on the football team: 55 people.
neither team minimum: 34; maximum: 55
Answer:
41101.750 to 43898.250
Step-by-step explanation:
Using this formula X ± Z (s/√n)
Where
X = 42500 --------------------------Mean
S = 6800----------------------------- Standard Deviation
n = 64 ----------------------------------Number of observation
Z = 1.645 ------------------------------The chosen Z-value from the confidence table below
Confidence Interval Z
80%. 1.282
85% 1.440
90%. 1.645
95%. 1.960
99%. 2.576
99.5%. 2.807
99.9%. 3.291
Substituting these values in the formula
Confidence Interval (CI) = 42500 ± 1.645(6800/√64)
CI = 42500 ± 1.645(6800/8)
CI = 42500 ± 1.645(850)
CI = 42500 ± 1398.25
CI = 42500+1398.25 ~. 42500-1398.25
CI = 43898.25 ~ 41101.75
In other words the confidence interval is from 41101.750 to 43898.250
To find a 90% confidence interval for the mean starting salary, use the formula CI = sample mean ± (Z * sample standard deviation / √n).
To find a 90% confidence interval for the mean starting salary, we will use the formula:
CI = sample mean ± (Z * sample standard deviation / √n)
Given that the sample mean is $42,500, the sample standard deviation is $6,800, and the number of college graduates is 64, we can substitute these values into the formula to calculate the confidence interval. The lower-bound is $41,101.87 and the upper-bound is $43,898.13.
