(-1,8) and (8,5). this is a coordinate distance wuestion that i rly need help on
Inga [223]

Answer:

3\sqrt{10} ≈ 9.45

Step-by-step explanation:

calculate the distance d between the points using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = (- 1, 8 ) and (x₂, y₂ ) = (8, 5 )

d = \sqrt{(8-(-1))^2+(5-8)^2}

   = \sqrt{(8+1)^2+(-3)^2}

   = \sqrt{9^2+9}

   = \sqrt{81+9}

   = \sqrt{90}

   = \sqrt{9(10)}

   = \sqrt{9} × \sqrt{10}

   = 3\sqrt{10} ← exact value

   ≈ 9.49 ( to 2 dec. places )

PLEASE HELP WILL MARK BRAINLIEST
zalisa [80]

Answer:

The probability of being older than 25 years and having a hemoglobin level above 11 is 19.58%. Since the question is referring to persons older than 25 years, we'll include all the data above 25 years.

So under 25-35 years old is 44 and under 35 years old is 40.

  44 + 40 = 84

  84 / 429 = 0.1958 or 19.58%

The probability of having a hemoglobin level above 11 is 35.66%. We would just get the ratio of 153 people who have hemoglobin level above 11 over the population of 429. 153 / 429 = 0.356643 or 35.66%

Being older than 25 years and having a hemoglobin level above 11 is not dependent on each other. Since the data is inversely proportional. The older the person gets, the lesser the number of people having hemoglobin level above 11 (A) 19.58%.

I hope this helps!

You purchased concentrated cleaner that must be diluted (watered down)
abruzzese [7]

Answer:

The volume of the concentrated 80 gallons mixture is 20 gallons

The volume of water in the 80 gallons mixture is 60 gallons

Step-by-step explanation:

The given parameters are;

The content of Container A = The cleaner

The concentration of the cleaner = 20% solution

The content of Container B = Pure water

The concentration of the desired solution = 5%

The volume of the required solution = 80 gallons

Let x represent the volume of the concentrated solution and y represent the volume of water in the 80 gallons mixture

Therefore, we have;

20/100 × x + y×0 = 5/100×80

x + y = 80

y = 80 - x

20/100 × x + (80 - x)×0 = 5/100×80

0.2·x = 4

x = 4/0.2 = 20

x = 20 gallons

y = 80 - x = 80 - 20 = 60

y = 60 gallons

The volume of the concentrated solution (80 gallons mixture) = x = 20 gallons

The volume of water in the 80 gallons mixture = y = 60 gallons.
