Answer:

Step-by-step explanation:

Answer:

3 ways

Step-by-step explanation:

2×3=6. That is how you do it

Answer:

Let Musa's mark be = m

Emmanuel's mark be = e

Faith's mark be = f

m = e + 7

e = 25

m = 25 + 7 = 32

f = 1/4 m + e

f = (1/4 × 32) + 25

f = 8 + 25

f = 33

The residuals of the linear regression equation are -1.36, 0.32, 0.01, 0.62, 0.17, -0.24, 0.89, 0.09, 0.18 and -0.7

The regression equation is given as:

y = 0.141x + 0.842

Next, we calculate the predicted values (y) at the corresponding x values.

So, we have:

y = 0.141 * 13.8 + 0.842 = 2.78

y = 0.141 * 18 + 0.842 = 3.38

y = 0.141 * 16.7 + 0.842 = 3.20

y = 0.141 * 18 + 0.842 = 3.38

y = 0.141 * 0.7 + 0.842 = 0.94

y = 0.141 * 21.9 + 0.842 = 3.93

y = 0.141 * 15.5 + 0.842 = 3.03

y = 0.141 * 9.2 + 0.842 = 2.14

y = 0.141 * 19.5 + 0.842 = 3.59

y = 0.141 * 16.7 + 0.842 = 3.20

The residuals are then calculated using:

Residual = Actual value - Predicted value

So, we have:

Residual = 1.42 - 2.78 = -1.36

Residual = 3.7 - 3.38 = 0.32

Residual = 3.21 - 3.20 = 0.01

Residual = 4 - 3.38 = 0.62

Residual = 1.11 - 0.94 = 0.17

Residual = 3.69 - 3.93 = -0.24

Residual = 3.92 - 3.03 = 0.89

Residual = 2.23 - 2.14 = 0.09

Residual = 3.77 - 3.59 = 0.18

Residual = 2.5 - 3.20 = -0.7

Hence, the residuals of the linear regression equation are -1.36, 0.32, 0.01, 0.62, 0.17, -0.24, 0.89, 0.09, 0.18 and -0.7

The approximation of the circumference of the ride is 138 feet to the nearest foot

The given parameters are:

The radius is calculated using:

[tex]r = \sqrt{(x - a)^2 + (y -b)^2}[/tex]

So, we have:

[tex]r = \sqrt{(16 - 0)^2 + (15.1 -0)^2}[/tex]

Evaluate

r = √484.01

Evaluate the square root

r = 22.0

The circumference is calculated using

C = 2πr

So, we have:

C = 2π * 22.0

Evaluate

C = 138

Hence, the approximation of the circumference of the ride to the nearest foot is 138 feet

Answer:

y = 6l + 43

Step-by-step explanation:

y=mx + b

y = y coordinate

m = slope

x = x coordinate

b = y intercept

The y intercept is when x = 0, so the initial cost before buying the laces, which was the cost of the sneakers

b = 43

The slope is you purchase one pair of laces, it increases by 6 each time

m = 6

The y coordinate will represent the total cost spent

y

The x coordinate will represent the total number of laces purchase and we are told that the variable is l

x = l

combine:

y = 6l + 43

Answer:

-8

Step-by-step explanation:

Solving for r means that we need to isolate r from the expression.

[tex] \frac{ - 8}{r + 6} = 4[/tex]

Multiply both sides by (r +6) to 'get rid' of the fraction:

-8= 4(r +6)

Expand:

-8= 4r +4(6)

-8= 4r +24

Minus 24 on both sides:

4r= -8 -24

4r= -32

Divide both sides by 4:

r= -32 ÷4

r= -8

Additional:

For a similar question on solving for a variable:

Answer:

r = -8

Step-by-step explanation:

-8/(r + 6) = 4
          -8 = 4(r + 6)
          -8 = 4r + 24
        -32 = 4r
          -8 = r

The number of customers served in the ice cream shop in June, July and August are 125, 25 and 250 customers respectively

let

Total = June + July + August

400 = x + (x- 100) + 2x

400 = x + x - 100 + 2x

400 = 4x - 100

400 + 100 = 4x

500 = 4x

x = 500/4

x = 125

So,

June = x

= 125 customers

July = x - 100

125 - 100

= 25 customers

August = 2x

= 2(125)

= 250 customers

Answer:

£ 2121.8

Step-by-step explanation:

The formula to find the compound interest is :

[tex]A=P(1+\frac{R}{100} )^n[/tex]

Here,

A = Amount ⇒ ?

P ⇒ Principal ⇒ £2000

R ⇒ Interest rate ⇒ 3%

n ⇒ Time  ⇒ 2 years

Let us find now.

[tex]A=P(1+\frac{R}{100} )^n[/tex]

[tex]A=2000(1+\frac{3}{100} )^2[/tex]

[tex]A=2000(1+0.03 )^2[/tex]

[tex]A=2000(1.03 )^2[/tex]

[tex]A=2000*1.0609[/tex]

[tex]A=2121.8[/tex]

Therefore, there will be £ 2121.8 in the bank account after 2 years.

The year, where the number of cars sold exceed 46,000 is 13496

The equation of the function is given as:

y = 4x + 2

When the sales exceed 46000;

It means that y > 46000

So, we have:

4x + 2 > 46000

Subtract 2 from both sides

4x > 45998

Divide both sides by 4

x > 11499.5

The year is then calculated as:

Year = 1996 + x

So, we have:

Year > 1996 + 11499.5

Evaluate

Year > 13495.5

Approximate

y > 13496

Hence; the year, where the number of cars sold exceed 46,000 is 13496
