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.

mr dela cruz uses 18 yards of cloth for making 5 pants how many pants will he make for 72 yards of cloth

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.

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

The equation 120+2.5x=220-3.5x

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

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.)

Answers

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

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:

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
