Answer:

The equation of the line is [tex]y = -\frac{1}{3}x - 8[/tex]

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

[tex]y = mx + b[/tex]

In which m is the slope and b is the y-intercept.

Slope of - 1/3

This means that [tex]m = -\frac{1}{3}[/tex]

So

[tex]y = -\frac{1}{3}x + b[/tex]

Through the point (-6, -6)

This means that when [tex]x = -6, y = -6[/tex]. So

[tex]y = -\frac{1}{3}x + b[/tex]

[tex]-6 = -\frac{1}{3}(-6) + b[/tex]

[tex]b + 2 = -6[/tex]

[tex]b = -8[/tex]

The equation of the line is [tex]y = -\frac{1}{3}x - 8[/tex]

Answer: 9e

Step-by-step explanation:

Answer: 75% of the rate lies in 47 per month and 55 per month.

Step-by-step explanation:

The mean rate for a satellite television from a sample of households was $51.00 per month,  with a standard deviation of $2.00 per month.

According to the Chebychev's Theorem, atleast [tex](1-\dfrac{1}{k^2})[/tex]  % of the data lies within k standard deviation from the mean.

For k=2

[tex]1-\dfrac1{2^2}=1-\dfrac14=\dfrac34=0.75\ or \ 75\%[/tex]

Alteast 75% of data lies within 2 standard deviation from mean.

i.e. 51-2(2) per month and 51+2(2) per month

i.e. 47 per month and 55 per month

Hence, 75% of the rate lies in 47 per month and 55 per month.

X= 18/3

X= 6

Answer:

13.5 = 9.5 + x

x=4

Step-by-step explanation:

In this problem, the price of the baseball cap, which is $9.50, and a baseball, whose price is unknown (and therefore must be the variable), total $13.50. So, to set up the equation add the two prices and set them equal to the total, 9.5+x=13.5.

Then, using the subtraction property of equality subtract 9.5 from both sides. This means x=4, so the baseball cost 4 dollars.

Answer:

it covered 54 and ran 6 per 9 second

Step-by-step explanation:

step 1. 78-24 = 54

step 2. 54/9 = 6

Answer:

B . 10.50

Why ? Because 8.50+3.50=12 , Then 12 × 5 = 60 , 2.50×3=7.5 , 60-7.5= 52.5 . divide 52.5 by 5 = 10.50 . So each friend paid 10.50

Answer:

d) 1.25 g

Step-by-step explanation:

If it has a half life of 40 days, there will be 5 half-lives in that span of time so if you divide 40 by 2, 5 times or just [tex]\frac{40}{2^{5} }[/tex], it will equal 1.25.

[tex]\frac{40}{2}=20\\[/tex]

[tex]\frac{20}{2} =10[/tex]

[tex]\frac{10}{2} =5[/tex]

[tex]\frac{5}{2} =2.5\\[/tex]

[tex]\frac{2.5}{2} =1.25[/tex]

Answer:

The slope is -7 . The y  intercept is (0 , 3)

Answer:

x= -1/7y+3/7

Step-by-step explanation:

step 1: −7x+3=y

Step 2: Add -3 to both sides.

−7x+3+−3=y+−3

−7x=y−3

Step 3: Divide both sides by -7.

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:

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

The total distance of Kite from the ground is 16.38 meters and this can be determined by using the trigonometric function.

Given :

The following steps can be used in order to determine the total distance of Kite from the ground:

Step 1 - The trigonometric functions can be used in order to determine the total distance of Kite from the ground.

Step 2 - The sine function is used to measure the distance. The mathematical expression of the sine function is:

[tex]\rm sin\theta = \dfrac{P}{H}[/tex]

where P is the perpendicular and H is the hypotenuse.

Step 3 - Now, substitute the values of the known terms in the above expression.

[tex]\rm sin55 = \dfrac{Distance}{20}[/tex]

Step 4 - Simplify the above expression.

Distance = 16.38 meters
