Answers
Answer:
[tex]\begin{array}{cccc}{Class} & {Frequency} & {Relative Frequency} &{Percent\ Frequency}\ \\ {12-14} & {2} & {0.05} & {5\%}& {15-17} & {8} & {0.200}&{20\%}& {18-20} & {11} & {0.275} & {27.5\%}& {21-23} & {10} & {0.250} &{25\%}& {24-26} & {9} & {0.225}&{22.5\%} & {Total} & {40} & {1} & {100\%}\ \end{array}[/tex]
Step-by-step explanation:
Required
Complete the table.
First, group the data according to the class.
So, we have:
12-14:- 14 12 --- Frequency is 2
15 - 17:- 16 16 16 16 16 17 16 15 --- Frequency is 8
18 - 20:- 19 19 19 18 19 18 20 20 19 20 20 --- Frequency is 11
21 - 23:- 21 23 21 22 21 23 23 22 22 22 --- Frequency is 10
24 - 26:- 25 24 24 25 25 24 26 24 24 --- Frequency is 9
Next, fill the class frequency column
[tex]\begin{array}{cc}{Class} & {Frequency} \ \\ {12-14} & {2} & {15-17} & {8} & {18-20} & {11} & {21-23} & {10} & {24-26} & {9}\ \end{array}[/tex]
Relative frequency is calculated by dividing each frequency by the total frequency (40).
So, we have:
[tex]\begin{array}{ccc}{Class} & {Frequency} & {Relative Frequency}\ \\ {12-14} & {2} & {0.05} & {15-17} & {8} & {0.200}& {18-20} & {11} & {0.275} & {21-23} & {10} & {0.250} & {24-26} & {9} & {0.225}\ \end{array}[/tex]
The percent frequency is calculated by multiplying the relative frequency by 100%.
So, we have:
[tex]\begin{array}{cccc}{Class} & {Frequency} & {Relative Frequency} &{Percent\ Frequency}\ \\ {12-14} & {2} & {0.05} & {5\%}& {15-17} & {8} & {0.200}&{20\%}& {18-20} & {11} & {0.275} & {27.5\%}& {21-23} & {10} & {0.250} &{25\%}& {24-26} & {9} & {0.225}&{22.5\%} & {Total} & {40} & {1} & {100\%}\ \end{array}[/tex]

Intrigued by a 2013 study at the University of Nebraska that suggested marijuana smokers may be thinner than other adults, a group of students did a project to explore the relationship between body mass index (BMI) and amount of time spent under the influence of marijuana (measured in hours per week). Based on a random sample of 33 students at their university, they used BMI as the response variable. The equation of the least-squares regression line is: hours per month under influence = 49.2−1.15 BMI. Also, r2=0.134 .
Answers
this question is incomplete, the complete question is:
1. is this model effective
2. what is the correlation coefficient for this data.
3. for a student with a bmi of 25, what is the predicted number of hours under the influence.
Step-by-step explanation:
1. first of all this model is not effective because we have r² as 0.134. this tells us that only 13.4 percent of the of the variations that exist in this data has been explained by the model
1. we get the correlation coefficient by
[tex]+-\sqrt{r^{2} }[/tex]
the regression slope coefficient has a negative sign. this is what we would use in calculating the correlation coefficient.
[tex]-\sqrt{r^{2} }[/tex]
= -√0.134
= -0.366
therefore the correlation coefficient is -0.366
2. to get the number of hours under the influence with a bmi of 25
the equation is
49.2-1.15bmi
= 49.2-1.15(25)
= 49.2-28.75
= 20.45

Answer:
5) The third side must be more than 4 and less than 14.
6) The third side must be more than 3 and less than 13.
Step-by-step explanation:
The third side must be more than the difference and less than the sum of the two numbers.
5) 9-5=4
9+5=14
So the third side must be more than 4 and less than 14.
6) 8-5=3
8+5=13
So the third side must be more than 3 and less than 13.

Roy weighs 120 pounds and plans to gain 2.5 pounds a week. Luis weighs 1 point
220 pounds and plans to lose 3.5 pounds a week. Which equation shows
when Roy and Luis will weigh the same?
Answers
Answer:
2.5x + 120 = -3.5x +220; after about 16.6 weeks Roy and Luis will weigh the same amount in pounds
Step-by-step explanation:
Roy's: y = 2.5x + 120
Luis': y = -3.5x + 220
x is representing the number of weeks and y is representing the total number of pounds each will weight after x weeks.
1) set the two equations equal to each other because you want them to weigh the same amount (this might be your equation if they don't want you to solve for the number of weeks)
2.5x + 120 = -3.5x +220
2) Solve for x to find after how many weeks they will weigh the same
2.5x = -3.5x +100
6x = 100
x = 16.6667 weeks

Answers
Answer:
18÷5= 3.6
3.6 = 4 yards
72 yards of cloth ÷ 4 yards of cloth = 18 pants
Step-by-step explanation:
3.6 yards rounded to the nearest is 4. So it takes 4 yards of cloth to make 1 pants. Since it takes 4 yards of cloth to make 1 pants, we simply divide 4 yards into 72 yards which equals to 18 pants.
