A large can is 12 inches high the radius of the top is 3.5 inches what is the area of a rectangular label that is wrapped around the can
Answer:
the aria is what you need to multiply together
Step-by-step explanation:
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 .
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

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?
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

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.
g (1 point) Find the angle between the diagonal of a cube of side length 8 and the diagonal of one of its faces, so that the two diagonals have a common vertex. The angle should be measured in radians. (Hint: we may assume that the cube is in the first octant, the origin is one of its vertices, and both diagonals start at the origin.)
Answer:
Angle between the diagonal of a cube of side length 8 and the diagonal of one of its faces is equal to [tex]0.6155[/tex] radian
Step-by-step explanation:
Please see the attached image for better understanding
Length of OB is equal to
[tex]\sqrt{19^2 + 19^2 }[/tex]
[tex]19\sqrt{2}[/tex]
Now the length of OE is equal to
[tex]\sqrt{19^2 + 19^2 + 19^2 } = 19 \sqrt{3}[/tex]
Now Angle BOE is equal to
[tex]cos^{-1} (\frac{722}{19\sqrt{2}* 19\sqrt{3} }) = 0.6155[/tex] radians
Angle between the diagonal of a cube of side length 8 and the diagonal of one of its faces is equal to [tex]0.6155[/tex] radian

Summarize the data by filling in the frequency (to the nearest whole number), the relative frequency (3 decimals), and the percent frequency (1 decimal) values below.
Class Frequency Relative Frequency Percent Frequency 12-14 % 15-17 % 18-20 % 21-23 % 24-26 % (Total) %
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]

mr dela cruz uses 18 yards of cloth for making 5 pants how many pants will he make for 72 yards of cloth
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.
Find the measure of the missing angle.
