Answer:

Y^= 1.767 + 0.6294X when rounded give s Y^= 1.77 +0.63X

b= 0.6294 rounded to 0.63

a= 1.77

The predicted lines are for each X and Y

3.340,3.96, 4.914, 5.228, and 5.543

Step-by-step explanation:

The data given is

Length (m)    Speed (m/s)              Predicted Line  

2.5                  3                                    3.340  

3.5                 4.5                                  3.96

5                   4.8                                  4.914

5.5                5.2                                 5.228

6                   5.5                                 5.543

The calculations are

                 Xsquare    XY   Y     X

                 6.25    7.5  3      2.5

                 12.25 15.75 4.5      3.5

                    25 24         4.8      5

                  30.25 28.6 5.2      5.5

                   36 33           5.5      6

Total       109.75 108.85   23         22.5

The estimated regression line of Y on X is

Y^ = a +bX

and two normal equations are

∑Y = na + b∑X

∑XY= a∑X + b∑X²

Now X`= ∑X/ n= 22.5/5=4.5

Y`= ∑Y/ n= 23/5= 4.6

b= n∑XY- (∑X)(∑Y) / n∑X²- (∑X²)

Putting the values

b= 5(108.85) - (23)(22.5)/ 5(109.75)- (22.5)²

b= 544.25-517.5/ 548.75-506.25

b= 26.75 /42.5

b= 0.6294

and

a= Y`- bX~= 4.6- 0.6294(4.5)= 4.6-2.823= 1.767

Hence the

desired estimated regression line of Y on X is

Y^= 1.767 + 0.6294X

Y^= 1.77 +0.63X

The estimated regression co efficient b= 0.6294 indicates that the values of Y increase by 0.6294 units for a unit increase in X.

Answer:

None of the above

Step-by-step explanation:

Measure of one base angle: 52°

Measure of the other base angle: 52°

Measure of the third angle: x

Sum of the measures of the three angles: 180°

Equation:

x + 52 + 52 = 180

x + 104 = 180

Answer: None of the above

Answer:

2 1/6 ft = 26 in

3 3/4 ft = 1 1/4 yrd

2 1/2 c = 1 1/4 p

3 2/3 yrs = 44 months

Step-by-step explanation:

Conversion:

ft to in = ft x 12

ft to yards = ft / 3

c to pints = c/2

yrs to months =  y x 12

If my answer is incorrect, pls correct me!

-Chetan K

Answer:

26 in, 1 1/4 yd, 1 1/4 pt, 44 months

Step-by-step explanation:

1ft=12in

12• 2 1/6=26in

3ft=1yd

3 3/4 ÷3= 1 1/4yd

2c=1pt

2 1/2 ÷ 2=1 1/4 pt

12months =1 year

3 2/3 • 12 = 44 months

Step-by-step explanation:

0900 to1030 is 1.5 h

Take 27/1.5

Then you will get the answer

Answer:

Half of 6 is 3(new radius)

3^3 = 9

9 x 3.14 = 28.26(area of circle)

Now we multiply by height

28.26 x 5 = 141.3

Now we divide by 3 since its part for the formula of finding the cone's volume:

141.3 x 1/3(basically just dividing by 3) = 47.1

Now let's find the volume of the cylinder:

3^3 = 9, 9 x 3.14 = 28.26

28.26 x 14 = 395.64

Now let's add the given volumes:

395.64  + 47.1 = 442.74 cm^3 is your answer.

We have to basically multiply:

11/17 x 475

And simplifying that we get

307.35

And since there can't be .35 person

So out final answer is 307

pls pls brainlist

Answer:1 / 15 of the pitcher

Step-by-step explanation:

The pitcher is 1/3 full and 5 people want to equally share it.

The equal amount is found by dividing 1/3 by 5:

= 1/3 ÷ 5

= 1/3 * 1/5

= 1/15 of the pitcher

Each person gets 1/5 of the pitcher

Answer:

x=37

Step-by-step explanation:

Complementary angles are a set of 2 angles that when added together, add up to 90. In order to solve for x, both angles have to be added and set to be equal to 90... but Jackie only used one of the angles, not both. The correct equation is: x+16+x=90

Answer:

Jackie forgot to add variable X

Step-by-step explanation:

Jackie Did

X +16= 90

equation :

x+x+16= 90

Answer:

Number of 1/8 cups of sugar needed = 2

Number of 1/8 cups of whole wheat flour needed = 6

Number of 1/8 cups of all purpose flour needed = 4

Step-by-step explanation:

Recipes Kelly needs:

Sugar = 1/4 cups

Whole wheat flour = 3/4 cups

All purpose flour = 1/2 cups

She could only find her ⅛ cup measuring cup.

How many ⅛ cups will she need for each ingredient?

Number of 1/8 cups of sugar needed = cups of Sugar needed / 1/8 cups

= 1/4 ÷ 1/8

= 1/4 × 8/1

= 8/4

= 2

Number of 1/8 cups of sugar needed = 2

Number of 1/8 cups of whole wheat flour needed = cups of whole wheat flour needed / 1/8 cups

= 3/4 ÷ 1/8

= 3/4 × 8/1

= 24/4

= 6

Number of 1/8 cups of whole wheat flour needed = 6

Number of 1/8 cups of all purpose flour needed = cups of all purpose flour needed ÷ 1/8 cups

= 1/2 ÷ 1/8

= 1/2 × 8/1

= 8/2

= 4

Number of 1/8 cups of all purpose flour needed = 4

Answer:

Katherine would have $109.54 more than Stella.

Step-by-step explanation:

Giving the following information:

Stella:

Initial investment (PV)= $6,100

Interest rate (i)= 0.065/12= 0.0054 per month

Number of periods (n)= 7*12= 84

Katherine:

Initial investment (PV)= $6,100

Interest rate (i)= 0.06625/4= 0.0167

Number of periods (n)= 7*4= 28

To calculate the future value, we need to use the following formula:

FV= PV*(1 + i)^n

Stella:

FV= 6,100*(1.0054^84)

FV= $9,589.5

Katherine:

FV= 6,100*(1.0167^28)

FV= $9,699.04

Difference= $109.54

Katherine would have $109.54 more than Stella.

Answer:

[tex]x=\frac{9}{25}[/tex]

x = 0.36

Step-by-step explanation:

5x/3 + 2/5 = 1

5x/3 + 2/5 - 2/5 = 1 - 2/5

[tex]\frac{5x}{3} = 0.6[/tex]

5x/3 × 3 = 0.6 × 3

5x = 1.8

5x ÷ 5 = 1.8 ÷ 5

[tex]x=\frac{9}{25}[/tex]

x = 0.36

Sorry if I am wrong. :) but it should be correct.

Answer:

A = 3 + 9/10

B = -(3 + 3/10)

Step-by-step explanation:

We have two numbers, A and B, such that:

A + B = 3/5

A - B = 7 + 1/5

To solve this, we first need to isolate one of the variables in one of the equations, I will isolate A in the first equation:

A = 3/5 - B

Now we can replace this in the other equation:

A - B = 7 + 1/5

(3/5 - B) - B = 7 + 1/5

3/5 - 2*B = 7 + 1/5

-2*B = 7 + 1/5 - 3/5

-2*B = 7 - 2/5 = 35/5 - 2/5 = 33/5

B = -(33/5)/2 = -33/10 = - 30/10 - 3/10 = -3 - 3/10 = -(3 + 3/10)

Now that we know the value of B, we can use the equation

A = 3/5 - B

To find the value of A:

A = 3/5 - ( -(3 + 3/10))

A = 3/5 + (3 + 3/10)  = 6/10 + 3 + 3/10 = 3 + 9/10

The numbers are:

A = 3 + 9/10

B = -(3 + 3/10)

Answer:

Since a fraction represents a division, we should do that division to know what the value of a fraction is. The larger numerator, the larger the value of the fraction will be; and the larger denominator, the smaller the fraction will be. ...

Answer:

it is approximately 12.57meters

Answer:

12.56 meters

Step-by-step explanation:

The area of a circle is πr², where r is the radius of the circle.

First we square the radius, which is 2. 2²=4.

Now our area is 4π.

Using 3.14 for π, we can say the area is 4 × 3.14, which is equal to 12.56
