Answer:

Tisco shop

Step-by-step explanation:

The computation is shown below;

For tisco,

= 20 ÷ 4 × £1.04

= £5.2

For Azda,

= 20 ÷ 5 × £1.35

= £5.4

As if we can see that the tisco cost is lower than the azda cost so here the best value represent the tisco shop

Answer:

Step-by-step explanation:

x-2y=2

2y=x-2

y=(x-2)/2

so the slope is 1/2

for lines to be perpendicular m1m2=-1 so the line must have a slope satisfying the condition

(1/2)m=-1

m=-2

the only line with a slope of -2 is

y=-2x+5

The equation represents a line that is perpendicular to the line x – 2y = 2 would have a slope of -2. The equation would be y = -2x + 5.

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

The given equation of line is

x-2y=2

2y = x - 2

y = (x - 2)/2

so, the slope of the equation is 1/2.

For the perpendicular lines

[tex]m_1m_2=-1[/tex]

So the line must have a slope that satisfies the condition.

(1/2) m = -1

m = -2

Hence, the only line with a slope of -2 is y = -2x + 5.

move the constant to the right change its sign

n= -16 - 4

calculate the difference

N= - 20

Answer:

[tex]n=-20[/tex]

Step-by-step explanation:

1) Subtract 2 from both sides.

[tex]\frac{n}{2} =-8-2[/tex]

2) Simplify −8−2  to −10.

[tex]\frac{n}{2} =-10[/tex]

3) Multiply both sides by 2.

[tex]n=-10*2[/tex]

4) Simplify 10 * 2 to 20.

Step-by-step explanation:

Answer:

95% Confidence Interval is; (  -5.344 to 11.344 )

Option b) -5.344 to 11.344 is the correct answer

Step-by-step explanation:

Given the data in the question;

Sample 1                 Sample 2

x"₁ = 45                   x"₂ = 42

S₁² = 85                  S₂² = 90

n₁ = 10                    n₂ = 12

df = [ S₁²/n₁ +  S₂²/n₂ ]² / [ ((S₁²/n₁)²/n₁-1) +  ((S₂²/n₂)²/n₂-1)) ]

we substitute

df = [ 10/10 +  90/12 ]² / [ ((85/10)²/10-1) +  ((90/12)²/12-1)) ] = 19.64 ≈ 20

df = 20

with 95% confidence interval

∝ = 1 - 0.95 = 0.05

∝/2 = 0.05/2 = 0.025

now, [tex]t_{\alpha /2,df} = t_{0.025, 20} = 2.086[/tex]    { from table }

95% confidence interval for N1 - N2

⇒ (x"₁ - x"₂) ± [tex]t_{\alpha /2,df}[/tex] × √( S₁²/n₁ +  S₂²/n₂ )

⇒ (45 - 42) ± 2.086 × √( 85/10 +  90/12 )

⇒ 3 ± 2.086 × 4

⇒ 3 ± 8.344

so;

Lower Limit = 3 - 8.344 = -5.344

Upper Limit = 3 + 8.344 = 11.344

Therefore, 95% Confidence Interval is; (  -5.344 to 11.344 )

Option b) -5.344 to 11.344 is the correct answer
