Answers
Answer:
the value of q = -3
Step-by-step explanation:
The computation of the equation is shown below:
Given that
q^2 + 6q + 9 = 0
q^2 + 3q+ 3q + 9
q(q + 3) + 3(q + 3)
(q+3) (q+3)
q = -3
Hence, after solving it the value of q = -3
What is the period of 1-sin 2πx/3? Please explain.
Answers
Answer:
Notice, period of function sin(kx) is 2π/k where k is constant (coefficient of x ) since coefficient of x in sin(2πx/3) is k=2π/3 hence the period of sin(2πx/3) is 2π/(2π/3)=3

The population of a city has been increasing by 2% annually. In 2000, the population was 315,000. Predict the population of the city in 2020. Round your answer to the nearest thousand.
Answers
Answer:
In 2020 there will be 468,073 people.
Step-by-step explanation:
Giving the following information:
Growth rate (g)= 2% = 0.02
Population 2,000= 315,000
Number of periods (n)= 20 years
To calculate the population in 2020, we need to use the following formula:
FV= PV*(1+g)^n
FV= 315,000*(1.02^20)
FV= 468,073
In 2020 there will be 468,073 people.

Find the area of this figure around your answer to the nearest 100. use 3.14 to approximate 3.14 as pi
Answers
Answer:
Area = 49.12 ft²
Step-by-step explanation:
The area of the figure = area of triangle + area of half of a circle
= ½*bh + ½(πr²)
b = 6 ft
h = 8 ft
r = ½ of 8 ft = 4 ft
π = 3.14
Plug in the values
Area of the figure = ½*6*8 + ½(3.14*4²)
Area = 24 + 25.12
Area = 49.12 ft²
Answer:
49.12

American League baseball teams play their games with the designated hitter rule, meaning that pitchers do not bat. The league believes that replacing the pitcher, traditionally a weak hitter, with another player in the batting order produces more runs and generates more interest among fans. Below are the average numbers of runs score in American League and National League stadiums for the first half of the 2001 season. **American:** 11.1, 10.8, 10.8, 10.3, 10.3, 10.1,10.0, 9.5, 9.4, 9.3, 9.2, 9.2, 9.0, 8.3 **National:** 14.0, 11.6, 10.4, 10.3, 10.2, 9.5, 9.5, 9.5, 9.5, 9.1, 8.8, 8.4, 8.3, 8.2, 8.1, 7.9 (a) Create two box plots to display this data and comment on what you see. (b) Estimate the mean number of runs scored in American League games with a 95% CI. What concerns do you have about making a similar CI for National League games
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given the data:
**American:**
11.1, 10.8, 10.8, 10.3, 10.3, 10.1,10.0, 9.5, 9.4, 9.3, 9.2, 9.2, 9.0, 8.3
**National:**
14.0, 11.6, 10.4, 10.3, 10.2, 9.5, 9.5, 9.5, 9.5, 9.1, 8.8, 8.4, 8.3, 8.2, 8.1, 7.9
Kindly view attached picture for boxplot :
Using the relation :
Mean ± Zcritical * s/sqrt(n)
Zcritical at 95% = 1.96
National league :
Mean = 9.58125
Standard deviation = 1.5
9.58125 - 1.96 * 1.5/4 = 8.84625
9.58125 + 1.96 * 1.5/4 = 10.31625
(8.84625 ; 10.31625)
American League :
Mean = 9.807
Standard deviation = 0.805
9.807 - 1.96 * 0.805/sqrt(14)= 9.3853152
9.807 + 1.96 * 0.805/sqrt(14) = 10.228684
(8.84625 ; 10.31625)
