On a coordinate grid, an island is located at (1,6). Another island is located at (4,9). What is the distance between the islands if the distance between consecutive grid lines represent 2 miles?

The mean and mean absolute deviation of this set of data will be 312. 9 and 0.19 respectively. The mean absolute deviation represents the average distance between each data value and the mean.

The average distance between each data point and the mean is the mean absolute deviation of a dataset. It offers us an indication of how variable a dataset.

Mean = 312. 9

absolute deviation = 0.19

Hence,the mean and mean absolute deviation of this set of data will be 312. 9 and 0.19 respectively. The mean absolute deviation represents. Average distance between each data value and the mean.

Step-by-step explanation:

Using point slope form ,

=> ( x - (-5) ) m = ( y - 4)

=> x + 5 = -3/5 ( y - 4)

=> 5x + 25 = -3y + 12

=> 5x + 3y + 13 = 0

Answer:

73.5 in^2

Step-by-step explanation:

Given data

Dimension of square= 3.5 inches

Area= 3.5^2

Area= 12.25 in^2

Number of square= 6

Hence the total area is

=12.25*6

=73.5 in^2

Answer:

Option B is correct

Step-by-step explanation:

Given

Distance from Alison's house to the mailbox  = [tex]\frac{2}{5}[/tex] miles

Distance from the mailbox to the bus stop [tex]\frac{1}{3}[/tex] miles

The total distance between Alison's house to the bus stop is

[tex]\frac{2}{5} + \frac{1}{3} \\\frac{6+5}{15} \\\frac{11}{15}[/tex]

Hence, option B is correct

Answer:

Step-by-step explanation:

H0 : μ = 46300

H1 : μ > 46300

α = 0.05

df = n - 1 = 45 - 1 = 44

Critical value for a one tailed t-test(since population standard deviation is not given).

Tcritical = 1.30

The test statistic :(xbar - μ) ÷ (s/sqrt(n))

The test statistic, t= (47800-46300) ÷ (5600√45)

t = 1500

t = 1500 / 834.79871

t = 1.797

The decision region :

Reject H0: if t value > critical value

1. 797 > 1.30

Tvalue > critical value ; We reject H0

Hence, there is sufficient evidence to conclude that cost has increased.

Answer:

(-1, 3)

Step-by-step explanation:

to solve using substitution, you have to know the value of either x or y. in this example, they gave you the value of y already: y=x+4.

this means you can substitute the y for (x+4). if we substitute y for (x+4) in the equation y=-5x-2, we get this:

(x+4)=-5x-2

then solve for x

6x=-6

so x=-1

since we know the x value, we can solve for y

y=x+4

y=-1+4

y=3

so the final answer is (-1, 3)

Answer:

(- 1, 3 )

Step-by-step explanation:

Given the 2 equations

y = x + 4 → (1)

y = - 5x - 2 → (2)

Substitute y = x + 4 into (2)

x + 4 = - 5x - 2 ( add 5x to both sides )

6x + 4 = - 2 ( subtract 4 from both sides )

6x = - 6 ( divide both sides by 6 )

x = - 1

Substitute x = - 1 into either of the 2 equations and evaluate for y

Substituting into (1)

y = - 1 + 4 = 3

solution is (- 1, 3 )

Answer:514 grams  of rice is in each of the 10 containers

Step-by-step explanation:

Amount of rice bought  =6 kilograms of rice.

6 kilograms =6000grams

Amount of rice reaming after filling 10 containers =860g

Amount used to fill up the containers ==6000grams-860grams =5140 grams

To get the amount filled inside the 10 containers since same amount is in each, we divide by 10

5140 grams/10=514 grams
